Project Apollo was a feat of human achievement akin to, and arguably greater than, the discovery of the New World. From 1962 to 1972, NASA conducted 17 crewed missions, six of which placed men on the surface of the moon. Since the Nixon administration put an end to Project Apollo, our extraterrestrial ambitions seem to have stalled along with our sense of national optimism. But is the American spirit of adventure, heroism, and willingness to take extraordinary risk a thing of the pastToday on the podcast, I talk with Charles Murray about what made Apollo extraordinary and whether we in the 21st century have the will to do extraordinary things. Murray is the co-author with Catherine Bly Cox of Apollo: The Race to the Moon, first published in 1989 and republished in 2004. He is also my colleague here at AEI.In This Episode* Going to the moon (1:35)* Support for the program (7:40)* Gene Kranz (9:31)* An Apollo 12 story (12:06)* An Apollo 11 story (17:58)* Apollo in the media (21:36)* Perspectives on space flight (24:50)Below is a lightly edited transcript of our conversationGoing to the moon (1:35)Pethokoukis: When I look at the delays with the new NASA go-to-the-moon rocket, and even if you look at the history of SpaceX and their current Starship project, these are not easy machines for mankind to build. And it seems to me that, going back to the 1960s, Apollo must have been at absolutely the far frontier of what humanity was capable of back then, and sometimes I cannot almost believe it worked. Were the Apollo people—the engineers—were they surprised it worked?Murray: There were a lot of people who, they first heard the Kennedy speech saying, “We want to go to the moon and bring a man safely back by the end of the decade,” they were aghast. I mean, come on! In 1961, when Kennedy made that speech, we had a grand total of 15 minutes of manned space flight under our belt with a red stone rocket with 78,000 pounds of thrust. Eight years and eight weeks later, about the same amount of time since Donald Trump was elected to now, we had landed on the moon with a rocket that had 7.6 million pounds of thrust, compared to the 78,000, and using technology that had had to be invented essentially from scratch, all in eight years. All of Cape Canaveral, those huge buildings down there, all that goes up during that time.Well, I'm not going to go through the whole list of things, but if you want to realize how incredibly hard to believe it is now that we did it, consider the computer system that we used to go to the moon. Jerry Bostick, who was one of the flight dynamics officers, was telling me a few months ago about how excited they were just before the first landing when they got an upgrade to their computer system for the whole Houston Center. It had one megabyte of memory, and this was, to them, all the memory they could ever possibly want. One megabyte.We'll never use it all! We'll never use all this, it’s a luxury!So Jim, I guess I'm saying a couple of things. One is, to the young’ins out there today, you have no idea what we used to be able to do. We used to be able to work miracles, and it was those guys who did it.Was the Kennedy speech, was it at Rice University?No, “go to the moon” was before Congress.He gave another speech at Rice where he was started to list all the things that they needed to do to get to the moon. And it wasn't just, “We have these rockets and we need to make a bigger one,” but there was so many technologies that needed to be developed over the course of the decade, I can't help but think a president today saying, “We're going to do this and we have a laundry list of things we don't know how to do, but we're going to figure them out…” It would've been called pie-in-the-sky, or something like that.By the way, in order to do this, we did things which today would be unthinkable. You would have contracts for important equipment; the whole cycle for the contract acquisition process would be a matter of weeks. The request for proposals would go out; six weeks later, they would've gotten the proposals in, they would've made a decision, and they'd be spending the money on what they were going to do. That kind of thing doesn't get done.But I'll tell you though, the ballsiest thing that happened in the program, among the people on the ground — I mean the ballsiest thing of all was getting on top of that rocket and being blasted into space — but on the ground it was called the “all up” decision. “All up” refers to the testing of the Saturn V, the launch vehicle, this monstrous thing, which basically is standing a Navy destroyer on end and blasting it into space. And usually, historically, when you test those things, you test Stage One, and if that works, then you add the second stage and then you add the third stage. And the man who was running the Apollo program at that time, a guy named Miller, made the decision they were going to do All Up on the first test. They were going to have all three stages, and they were going to go with it, and it worked, which nobody believed was possible. And then after only a few more launches, they put a man on that thing and it went. Decisions were made during that program that were like wartime decisions in terms of the risk that people were willing to take.One thing that surprises me is just how much that Kennedy timeline seemed to drive things. Apollo seven, I think it was October ’68, and that was the first manned flight? And then like two months later, Apollo 8, we are whipping those guys around the moon! That seems like a rather accelerated timeline to me!The decision to go to the moon on Apollo 8 was very scary to the people who first heard about it. And, by the way, if they'd had the same problem on Apollo 8 that they'd had on Apollo 13, the astronauts would've died, because on Apollo 8 you did not have the lunar module with them, which is how they got back. So they pulled it off, but it was genuinely, authentically risky. But, on the other hand, if they wanted to get to the moon by the end of 1969, that's the kind of chance you had to take.Support for the Program (7:40)How enthusiastic was the public that the program could have withstood another accident? Another accident before 11 that would've cost lives, or even been as scary as Apollo 13 — would we have said, let's not do it, or we're rushing this too much? I think about that a lot now because we talk about this new space age, I'm wondering how people today would react.In January, 1967, three astronauts were killed on the pad at Cape Canaveral when the spacecraft burned up on the ground. And the support for the program continued. But what's astonishing there is that they were flying again with manned vehicles in September 1967. . . No, it was a year and 10 months, basically, between this fire, this devastating fire, a complete redesign of the spacecraft, and they got up again.I think that it's fair to say that, through Apollo 11, the public was enthusiastic about the program. It's amazingly how quickly the interest fell off after the successful landing; so that by the time Apollo 13 was launched, the news programs were no longer covering it very carefully, until the accident occurred. And by the time of Apollo 16, 17, everybody was bored with the program.Speaking of Apollo 13, to what extent did that play a role in Nixon's decision to basically end the Apollo program, to cut its budget, to treat it like it was another program, ultimately, which led to its end? Did that affect Nixon's decision making, that close call, do you think?No. The public support for the program had waned, political support had waned. The Apollo 13 story energized people for a while in terms of interest, but it didn't play a role. Gene Kranz (9:31)500 years after Columbus discovering the New World, we talk about Columbus. And I would think that 500 years from now, we'll talk about Neil Armstrong. But will we also talk about Gene Kranz? Who is Gene Kranz and why should we talk about him 500 years from now?Gene Kranz, also known as General Savage within NASA, was a flight director and he was the man who was on the flight director's console when the accident on 13 occurred, by the way. But his main claim to fame is that he was one of — well, he was also on the flight director's desk when we landed. And what you have to understand, Jim, is the astronauts did not run these missions. I'm not dissing the astronauts, but all of the decisions . . . they couldn't make those decisions because they didn't have the information to make the decisions. These life-and-death decisions had to be made on the ground, and the flight director was the autocrat of the mission control, and not just the autocrat in terms of his power, he was also the guy who was going to get stuck with all the responsibility if there was a mistake. If they made a mistake that killed the astronauts, that flight director could count on testifying before Congressional committees and going down in history as an idiot.Somebody like Gene Kranz, and the other flight director, Glynn Lunney during that era, who was also on the controls during the Apollo 13 problems, they were in their mid-thirties, and they were running the show for one of the historic events in human civilization. They deserve to be remembered, and they have a chance to be, because I have written one thing in my life that people will still be reading 500 years from now — not very many people, but some will — and that's the book about Apollo that Catherine, my wife, and I wrote. And the reason I'm absolutely confident that they're going to be reading about it is because — historians, anyway, historians will — because of what you just said. There are wars that get forgotten, there are all sorts of events that get forgotten, but we remember the Trojan War, we remember Hastings, we remember Columbus discovering America. . . We will remember for a thousand years to come, let alone 500, the century in which we first left Earth. An Apollo 12 story (12:06)If you just give me a story or two that you'd like to tell about Apollo that maybe the average person may have never heard of, but you find . . . I'm sure there's a hundred of these. Is there one or two that you think the audience might find interesting?The only thing is it gets a little bit nerdy, but a lot about Apollo gets nerdy. On Apollo 12, the second mission, the launch vehicle lifts off and into the launch phase, about a minute in, it gets hit by lightning — twice. Huge bolts of lightning run through the entire spacecraft. This is not something it was designed for. And so they get up to orbit. All of the alarms are going off at once inside the cabin of the spacecraft. Nobody has the least idea what's happened because they don't know that they got hit by lightning, all they know is nothing is working.A man named John Aaron is sitting in the control room at the EECOM’s desk, which is the acronym for the systems guide who monitored all the systems, including electrical systems, and he's looking at his console and he's seeing a weird pattern of numbers that makes no sense at all, and then he remembers 15 months earlier, he'd just been watching the monitor during a test at Cape Canaveral, he wasn't even supposed to be following this launch test, he was just doing it to keep his hand in, and so forth, and something happened whereby there was a strange pattern of numbers that appeared on John Aaron's screen then. And so he called Cape Canaveral and said, what happened? Because I've never seen that before. And finally the Cape admitted that somebody had accidentally turned a switch called the SCE switch off.Okay, so here is John Aaron. Apollo 12 has gone completely haywire. The spacecraft is not under the control of the astronauts, they don't know what's happened. Everybody's trying to figure out what to do.John Aaron remembers . . . I'm starting to get choked up just because that he could do that at a moment of such incredible stress. And he just says to the flight director, “Try turning SCE to auxiliary.” And the flight director had never even heard of SCE, but he just . . . Trust made that whole system run. He passes that on to the crew. The crew turns that switch, and, all at once, they get interpretable data back again.That's the first part of the story. That was an absolutely heroic call of extraordinary ability for him to do that. The second thing that happens at that point is they have completely lost their guidance platform, so they have to get that backup from scratch, and they've also had this gigantic volts of electricity that's run through every system in the spacecraft and they have three orbits of the earth before they have to have what was called trans lunar injection: go onto the moon. That's a couple of hours’ worth.Well, what is the safe thing to do? The safe thing to do is: “This is not the right time to go to the moon with a spacecraft that's been damaged this way.” These guys at mission control run through a whole series of checks that they're sort of making up on the fly because they've never encountered this situation before, and everything seems to check out. And so, at the end of a couple of orbits, they just say, “We're going to go to the moon.” And the flight director can make that decision. Catherine and I spent a lot of time trying to track down the anguished calls going back and forth from Washington to Houston, and by the higher ups, “Should we do this?” There were none. The flight director said, “We're going,” and they went. To me, that is an example of a kind of spirit of adventure, for lack of a better word, that was extraordinary. Decisions made by guys in their thirties that were just accepted as, “This is what we're going to do.”By the way, Gene Kranz, I was interviewing him for the book, and I was raising this story with him. (This will conclude my monologue.) I was raising this story with him and I was saying, “Just extraordinary that you could make that decision.” And he said, “No, not really. We checked it out. The spacecraft looked like it was good.” This was only a year or two after the Challenger disaster that I was conducting this interview. And I said to Gene, “Gene, if we had a similar kind of thing happen today, would NASA ever permit that decision to be made?” And Gene glared at me. And believe me, when Gene Kranz glares at you, you quail at your seat. And then he broke into laughter because there was not a chance in hell that the NASA of 1988 would do what the NASA of 1969 did.An Apollo 11 story (17:58)If all you know about Apollo 11 is what you learned in high school, or maybe you saw a documentary somewhere, and — just because I've heard you speak before, and I've heard Gene Kranz speak—what don't people know about Apollo 11? There were — I imagine with all these flights — a lot of decisions that needed to be made probably with not a lot of time, encountering new situations — after all, no one had done this before. Whereas, I think if you just watch a news report, you think that once the rocket's up in the air, the next thing that happens is Neil Armstrong lands it on the moon and everyone's just kind of on cruise control for the next couple of days, and boy, it certainly doesn't seem like that.For those of us who were listening to the landing, and I'm old enough to have done that, there was a little thing called—because you could listen to the last few minutes, you could listen to what was going on between the spacecraft and mission control, and you hear Buzz Aldrin say, “Program Alarm 1301 . . .  Program Alarm 1301 . . .” and you can't…   well, you can reconstruct it later, and there's about a seven-second delay between him saying that and a voice saying, “We're a go on that.” That seven seconds, you had a person in the back room that was supporting, who then informed this 26-year-old flight controller that they had looked at that possibility and they could still land despite it. The 26-year-old had to trust the guy in the back room because the 26-year-old didn't know, himself, that that was the case. He trusts him, he tells the flight director Gene Kranz, and they say, “Go.” Again: Decision made in seven seconds. Life and death. Taking a risk instead of taking the safe way out.Sometimes I think that that risk-taking ethos didn't end with Apollo, but maybe, in some ways, it hasn't been as strong since. Is there a scenario where we fly those canceled Apollo flights that we never flew, and then, I know there were other plans of what to do after Apollo, which we didn't do. Is there a scenario where the space race doesn't end, we keep racing? Even if we're only really racing against ourselves.I mean we've got . . . it's Artemis, right? That's the new launch vehicle that we're going to go back to the moon in, and there are these plans that somehow seem to never get done at the time they're supposed to get done, but I imagine we will have some similar kind of flights going on. It's very hard to see a sustained effort at this point. It's very hard to see grandiose effort at this point. The argument of, “Why are we spending all this money on manned space flight?” in one sense, I sympathize with because it is true that most of the things we do could be done by instruments, could be done by drones, we don't actually have to be there. On the other hand, unless we're willing to spread our wings and raise our aspirations again, we're just going to be stuck for a long time without making much more progress. So I guess what I'm edging around to is, in this era, in this ethos, I don't see much happening done by the government. The Elon Musks of the world may get us to places that the government wouldn't ever go. That's my most realistic hope.Apollo in the Media (21:36)If I could just give you a couple of films about the space program and you just… thought you liked it, you thought it captured something, or you thought it was way off, just let just shoot a couple at you. The obvious one is The Right Stuff—based on the Tom Wolfe book, of course.The Right Stuff was very accurate about the astronauts’ mentality. It was very inaccurate about the relationship between the engineers and the astronauts. It presents the engineers as constantly getting the astronauts way, and being kind of doofuses. That was unfair. But if you want to understand how the astronauts worked, great movieApollo 13, perhaps the most well-known.Extremely accurate. Extremely accurate portrayal of the events. There are certain things I wish they could include, but it's just a movie, so they couldn't include everything. The only real inaccuracy that bothered me was it showed the consoles of the flight controllers with colored graphics on them. They didn't have colored graphics during Apollo! They had columns of white numbers on a black background that were just kind of scrolling through and changing all the time, and that's all. But apparently, when their technical advisor pointed that out to Ron Howard, Ron said, “There are some things that an audience just won't accept, but they would not accept.”That was the leap! First Man with Ryan Gosling portraying Neil Armstrong.I'll tell you: First place, good movie—Excellent, I think.Yeah, and the people who knew Armstrong say to me, it's pretty good at capturing Armstrong, who himself was a very impressive guy. This conceit in the movie that he has this little trinket he drops on the moon, that was completely made up and it's not true to life. But I'll tell you what they tell me was true to life that surprised me was how violently they were shaken up during the launch phase. And I said, “Is that the way it was, routinely?” And they said, yeah, it was a very rough ride that those guys had. And the movie does an excellent job of conveying something that somebody who'd spent a lot of time studying the Apollo program didn't know.I don't know if you've seen the Apple series For All Mankind by Ronald D. Moore, which is based on the premise I raised earlier that Apollo didn’t end, we just kept up the Space Race and we kept advancing off to building moon colonies and off to Mars. Have you seen that? And what do you think about it if you have? I don't know that you have.I did not watch it. I have a problem with a lot of these things because I have my own image of the Apollo Program, and it drives me nuts if somebody does something that is egregiously wrong. I went to see Apollo 13 and I'm glad I did it because it was so accurate, but I probably should look at For All Mankind.Very reverential. A very pro-space show, to be sure. Have you seen the Apollo 11 documentary that's come out in the past five years? It was on the big screen, it was at theaters, it was a lot of footage they had people had not seen before, they found some old canisters somewhere of film. I don’t know if you've seen this. I think it's just called Apollo 11.No, I haven't seen that. That sounds like something that I ought to look at.Perspectives on space flight (24:50)My listeners love when I read . . . Because you mentioned the idea of: Why do we go to space? If it's merely about exploration, I suppose we could just send robots and maybe eventually the robots will get better. So I want to just briefly read two different views of why we go to space.Why should human beings explore space? Because space offers transcendence from which only human beings can benefit. The James Webb Space Telescope cannot articulate awe. A robot cannot go into the deep and come back with soulful renewal. To fully appreciate space, we need people to go there and embrace it for what it fully is. Space is not merely for humans, nor is space merely for space. Space is for divine communion.That’s one view.The second one is from Ayn Rand, who attended the Apollo 11 moon launch. This is what Ayn Rand wrote in 1969:The next four days were torn out of the world’s usual context, like a breathing spell with a sweep of clean air piercing mankind’s lethargic suffocation. For thirty years or longer, the newspapers had featured nothing but disasters, catastrophes, betrayals, the shrinking stature of man, the sordid mess of a collapsing civilization; their voice had become a long, sustained whine, the megaphone a failure, like the sound of the Oriental bazaar where leprous beggars, of spirit or matter, compete for attention by displaying their sores. Now, for once, the newspapers were announcing a human achievement, were reporting on a human triumph, were reminding us that man still exists and functions as a man. Those four days conveyed the sense that we were watching a magnificent work of art—a play dramatizing a single theme: the efficacy of man’s mind.Is the answer for why we go to space, can it be found in either of those readings?They're going to be found in both. I am a sucker for heroism, whether it's in war or in any other arena, and space offers a kind of celebration of the human spirit that is only found in endeavors that involve both great effort and also great risk. And the other aspect of transcendence, I'm also a sucker for saying the world is not only more complicated than we know, but more complicated than we can imagine. The universe is more complicated than we can imagine. And I resonate to the sentiment in the first quote.Faster, Please! is a reader-supported publication.

As private and government interest in nuclear fusion technology grows, an array of startups have arisen to take on the challenge, each with their own unique approach. Among them: LaserFusionX. Today on Faster, Please!—The Podcast, I talk with CEO Stephen Obenschain about the viability of fusion energy, and what sets his approach apart.Obenschain is the president of LaserFusionX. He was formerly head of the Plasma Physics Division branch at the U.S. Naval Research Laboratory.In This Episode* Viability of commercial fusion (0:58)* The LaserFusionX approach (7:54)* Funding the project (10:28)* The vision (12:52)Below is a lightly edited transcript of our conversationViability of commercial fusion (0:58)Pethokoukis: Steve, welcome to the podcast.Obenschain: Okay, I'm glad to talk with you. I understand you're very interested in high-tech future power sources, not so high tech right now are windmills…Well, I guess they're trying to make those more high tech, as well. I recall that when the Energy Department, the National Ignition Laboratory [NIF], they had the—I guess that's over about maybe 15 months ago—and they said they had achieved a net gain nuclear fusion, using lasers, and the energy secretary made an announcement and it was a big deal because we had never done that before by any means. But I remember very specifically people were saying, “Listen, it's a great achievement that we've done this, but using lasers is not a path to creating a commercial nuclear reactor.” I remember that seemed to be on the news all the time. But yet you are running a company that wants to use lasers to create a commercial fusion reactor. One, did I get that right, and what are you doing to get lasers to be able to do that?I don't know why people would come to that conclusion. I think we are competitive with the other approaches, which is magnetic fusion, where you use magnetic fields to confine a plasma and get to fusion temperatures. The federal government has supported laser fusion since about 1972, starting with the AEC [Atomic Energy Commission]. Originally it was an energy program, but it has migrated to being in support stockpiled stewardship because, with laser fusion, you can reach physics parameters similar to what occur in thermonuclear weapons.Yeah. So that facility is about nuclear weapons testing research, not creating a reactor—a fusion reactor.Yeah. All that being said, it does advance the physics of laser fusion energy, and what the National Ignition Facility did is got so-called ignition, where the fuel started a self-sustaining reaction where it was heating itself and increasing the amount of fusion energy. However, the gain was about three, and one of the reasons for that is they use so-called indirect drive, where the laser comes in, heats a small gold can, and the X-rays from that then that drive the pellet implosion, which means you lose about a factor of five in the efficiency. So it's limited gain you get that way.Your way is different. It sort of cuts out the middleman.Okay. The better way to go—which, we're not the only ones to do this—is direct drive, where the laser uniformly illuminates the target at the time that Livermore got started with indirect drive, we didn't have the technologies to uniformly illuminate a pellet. First at NRL [Naval Research Laboratories], and then later at University of Rochester in Japan, they developed techniques to uniformly illuminate the pellets. The second thing we're doing is using the argon fluoride laser. The argon fluoride laser has been used in lithography for many years because it's deep UV.The unique thing we have been trying to do—this was when I was supervising the program at the Naval Research Laboratory—was to take it up to high energy. We started years ago with a similar Krypton fluoride laser, built the largest operating target shooter with that technology, demonstrated the high repetition rate operation that you need for energy and NIF will shoot a few times a day—you need five to 10 shots per second to do a power plant—demonstrated that on a krypton fluoride laser, and, more recently, we switched to the focus to argon fluoride, which is deeper UV and more efficient than the Krypton  fluoride. And that basically—at NRL when I was supervising it—reached the energy record for that technology. But we've got a long ways to go to get it to the high energy needed for a power plant.Now, what the immediate goal of my company is to get the funds and to build a beam line of argon fluoride that would have the energy and performance needed for a power plant. One of the advantages to laser fusion: you want have a situation where I'm building more than one of something, so for an implosion facility, you have many beam lines, so you build one and then you have the advantage of building more, and a learning curve as you go toward a power plant. We developed a phase program where first we build the beamline, then we build a NIF-like implosion facility only operating with the argon fluoride, demonstrate the high gain—which is a hundred plus for a power plant—and then, after doing that, do the physics in parallel, develop the other technology you need, like low-cost targets. (They can't be expensive. The NIF targets are probably tens of thousands. We can't spend that.) We're going 10 shots per second. All the technologies required for a pilot power plant build a pilot power plant, which, in my view could be maybe 400 megawatts electricity. However, its main function would be to develop the procedures, test the components, and so forth for the follow-on, mass-produced power plants. So one, when you build a pilot power plant, you want to operate it for a few years to get the kinks out before going to mass production. The vision is to go from the beginning of that to the end in about 16 years.So the challenges are you have to generate enough heat, and you have to be able to do this over, and over, and over again.Right. That's right. It has to be high reliability. For an implosion facility, a hundred-thousand-shot reliability is okay. For a power plant, it's got to be in the billion-shot class.And at this point, the reason you think this is doable is what?I think we have confidence in the pellet designs. I have a lot, and I have colleagues that have a lot of experience with building large excimer systems: KrF [Krypton Fluoride Excimer Laser], ArF [Argon Fluoride Excimer Laser]…Those are lasers?Yes. And we have credible conceptual designs for the facility.There’s a lot of companies right now, and startups, with different approaches. I would assume you think this is the most viable approach, or has some other advantages over some of the other things we're seeing with Commonwealth Fusion Systems, which gets mentioned a lot, which is using a different approach. So is the advantage you think it's easier to get to a reactor? What are the advantages of this path?The LaserFusionX approach (7:54)Well, for one, it's different. It's different challenges from the Commonwealth Fusion Systems. There is overlap, and there should be collaboration. For example, you have to, theirs is also deuterium-tritium. However, the physics challenges are different. I think we're farther along in laser fusion to be able—it's a simpler situation than you have. It's very complex interactions in tokamak, and you also have things… have you ever heard of a disruption? Basically it's where all of the magnetic energy all of a sudden goes to the wall, and if you have something like what Commonwealth Fusion Systems—they’ve got to be careful they don't get that. If they do, it would blow a hole in the wall. We don't have that problem with laser fusion. I think we're further along in understanding the physics. Actually, the National Ignition Facility is ahead of the highest fusion gains they've gotten in facilities. I think that they're somewhere just below one or so with the jet. They're up at one and a half. To what extent are the challenges of physics and science, and to what extent are the challenges engineering?Well, the physics has to guide the precision you have on the laser. And I won't say we're 100 percent done in the physics, but we're far enough along to say, okay. That's one reason where I envision building an implosion facility before the pilot power plant so we can test the codes and get all the kinks out of that. Nothing's easy. You have to get the cost of the targets down. The laser, okay, we've demonstrated, for example, at NRL—And NRL is…?Naval Research Laboratory.Naval Research Lab, right.A hundred-shot operation of the KrF laser. We use spark gap for that. We need to go to solid state pulse power, got up to 10 million shots. We need to get from there to a billion shots. And some of that is just simply improving the components. It's straightforward, but you've got to put time into it. I think you need really smart people doing this, that are creative—not too creative, but where you need to be creative, you are creative, and I think if, basically, if you can get the support, for example, to build (a beam line is somewhere around a hundred million dollars). To build the implosion facility and pilot power plant, you're getting into the billion shot, billion dollar class and you have to get those resources and be sure enough that, okay, if the investors put this money in, they're going to get a return on it.Funding the project (10:28)I think people who are investing in this sector, I would assume they may be more familiar with some of the other approaches, so what is the level of investor interest and what is the level of Department of Energy interest?Well, one of the challenges is that, historically, the Department of Energy has put money into two pots. One, laser fusion for stockpile stewardship, and magnetic fusion for energy. That's starting to change, but they don't have a lot of money involved yet, to put money into laser fusion or inertial fusion energy. And one of my challenges is not that the companies are aware of magnetic fusion, they don't understand the challenges of that, or laser fusion, or what's a good idea and a bad idea. And like Commonwealth Fusion systems I think has a good technical basis. If you go the next one down to Helion Energy, they're claiming they can burn helium three made from deuterium interactions, which violates textbook physics, so I'm very… I wonder about that.Would it surprise you, at the end of the day, that there are multiple paths to a commercial fusion reactor?Oh no. I think there are multiple paths to getting to where I get fusion burn, and maybe I make electricity. I think ultimately the real challenge for us is: Can we go reasonably fast? At 16 years, I'm considered somewhat slower than others. The ones that are saying five years I think are delusional. The ones that are saying 50 years, or say never, I don't think understand that yeah, we're pretty far along in this.How big, or rather, how small, theoretically, could one of these reactors be? I know there's been talk about using nuclear fusion as a way to provide power for these new data centers that gobble up so much power that they're using AI for. Would this be the kind of reactor that would power a city power, a big factory power, a data center, all of the above?I think you can get down, at least with our approach, to a couple hundred megawatts. However, my own vision is you're probably better off having power stations for some of the nuclear—with these, the big nuclear plants have multiple reactors at one place, and you'd get the advantage, for example, in our case, to just simply have one target factory and so forth. I don't think we're going to be able to compete. I don't know how small modular reactors go—a hundred megawatts or so, I would guess, and probably can't get down there, but one of my own goals is to get the size down as much as possible, but I think we're talking about hundreds of megawatts. The vision (12:52)What's the big vision? Why are you doing this?Why am I doing it?Yeah, what's the vision? What drives you and where do you think this goes over the next two decades?I may have the best route to get there. If I thought one of these other ones were going to get there, no problem… but all of us have challenges, and I think we can get there. I think from a standing start. As far as getting investment, I've just had pre-seed money, I don't have the big bucks yet. I’ve brought on people that are more experienced than me at extracting money from VCs and investors. (I was told you know a few billionaires.) Basically, for me, I need a few tens of millions to get started—like I'd say, about a hundred million to build the beamline. And then after that… actually I have a conference call on Friday with a representative of the investment bank industry that is very dubious about fusion.I mean, you can understand the skepticism, as a technology. What do they say? “It's the future of energy and always will be.”But the really good thing, I think, about the private investment is that the public investment has been too much focus on big machines which will give you physics, but have pretty much zero chance of being a direct path to fusion energy. You know, $25 billion and I make 500 megawatts thermal, occasionally, and we show that to a power plant executive, they're going to say, “You're kidding me.” We hope to get down cost for the power plants in the few-billion-dollar range.Faster, Please! is a reader-supported publication.

Readers and listeners of Faster, Please! know how incredible the untapped potential of nuclear power truly is. As our society (hopefully) begins to warm to the idea of nuclear as an abundant, sustainable, and safe source of energy, a new generation of engineers and entrepreneurs is developing a whole new model of nuclear power: the microreactor.Here on this episode of Faster, Please! — The Podcast, I talk with James Walker, a nuclear physicist and CEO of NANO Nuclear Energy about the countless applications of his company’s under-development, mobile, and easily-deployable nuclear reactors.In This Episode* Why the microreactor? (1:14)* The NANO design plan (7:11)* The industry environment (11:42)* The future of the microreactor (13:45Below is a lightly edited transcript of our conversationWhy the microreactor? (1:14)Pethokoukis : James, welcome to the podcast.Walker: I would say the way NANO got going is probably of interest, then. When we first entered the nuclear space, and my background is a nuclear physicist, nuclear engineer, so I knew that there's a very high bar to entry in nuclear and there's a lot of well-established players in the space. But, really, when we actually took a look at the whole landscape, most of the development was in the SMR space, the Kairos, the Terra Powers, the NuScales, and we could see what they were doing: They were aiming for a much more manufactural reactor that could deploy a lot faster. It was going to be a lot smaller, fewer mechanical components, smaller operating staff to bring down costs. So that all made a lot of sense, but what I think was missing in the market—and there are a few companies involved in this—was that the microreactor space looked to be the larger potential market. And I say that because microreactors are more readily deployable to places like remote mining sites, remote habitation, disaster relief areas, military bases, island communities… you put them on maritime vessels to replace bunk fuel, charging stations for EV vehicles... Essentially hundreds of thousands of potential locations competing against diesel generators, which, up until now, up until microreactors, had no competition. So the big transformative change here is—obviously SMRs are going to contribute that, but—micro reactors can completely reshape the energy landscape and that's why it's exciting. That's the big change.You gave some examples, so I want you to give me a couple more examples, but I'll say that I was thinking the other day about the expansion, partially due to AI, of these big data centers around the country. Is that the kind of thing—and you can give me other examples, as well—of where a much smaller microreactor might be a good fit for it, and also tell me, just how big are these reactors?AI centers and data centers are particularly a big focus of tech at the moment. Microsoft even have people deliberately going out and speaking to nuclear companies about being able to charge these new stations because they want these things to be green, but they also want them in locations which aren't readily accessible to the grid. And a lot of the time, some of the power requirements of these things might be bigger than the town next to them where they've got these things. So their own microreactor or SMR system is actually a really good way of solving this where it's zero carbon-emitting energy, you can put it anywhere, and it is the most consistent form of energy. Now you can out-compete diesel in that front, it can go outcompete, wind or solar. It really has no competitors. So they are leaning in that direction and a lot of the big drive in nuclear at the moment is coming from industry. So that's the big change, I think. It's not strictly now a government-pushed initiative.What's the difference between these and the SMR reactors, which my listeners and readers might be a little bit more familiar with?SMRs, the small modular reactors, obviously if you think of a large conventional nuclear power station, you're thinking dozens and dozens of acres of land being occupied by essentially a big facility. An SMR brings that down by an order of magnitude. You still need to probably have an area about 10 city blocks, but the reactor itself is much, much smaller, occupied by a much smaller footprint than that.Microreactors are much smaller, again, so if you take our design as an example, the whole system, the core and the turbine that produces the electricity, all fits within an ISO container. If you think of the standard shipping container you see on the back of a ship or you see on the back of a truck or a train, that's where you're really looking at. And the reason for that is that we're trying to make it as deployable and as mobile as possible. So conventional transportation—infrastructure, trucks, trains, ships—get these things anywhere in the world. Helicopter them in, if you really want. And once they're down there you've got 10, 15, 20 years of power consistently without that constant need to import fuel like you would with the diesel generator. That's the real big advantage of these things. Obviously SMRs don't have that ability, but they are more powerful machines. So you're powering cities, or bit towns, and that kind of thing. They are catering to different markets. They're not exactly competitors, they're very complimentary.But even for big grid systems, micro reactors could play a big part because they could be intermittently placed within a grid system so that you have backup power systems all the time that's not reliant on one major area to produce power for the entire grid system. It can always draw power from wherever it needs. And there's a big advantage to micro correctors there.Other examples of where microreactors could be used: We know that the military is very interested because they have an obligation to be able to self-power for at least two weeks. And obviously micros can take you well beyond that for, like, 50 years, so that easily meets their requirements. They're looking to get rid of diesel and replace them with microreactors and they're putting money in that space.I would say a big market is going to be things like island communities that predominantly run on diesel at the moment, and that means it's expensive and it's polluting, and they're constantly bringing in diesel on a daily basis.  Countries like the Philippines, Indonesia, where they have the majority of their population on these island communities that all run on diesel, you would essentially be taking hundreds of millions of people off diesel generator and putting them onto nuclear if you could bring in that technology to these areas.And the US actually has an enormous population on island communities that run on diesel, too, that could be replaced with microreactors, and you could then have a zero carbon-emitting solution to energy requirements and less energy insecurity.  The NANO design plan (7:11)Would they need to be refueled and how many people would it take? How many technical people would you need to operate one of them?The idea here with our reactors is that we don't want to refuel at-site. What we would likely do is just decommission that reactor and remove it and we would just bring in a replacement. It's this less messy, there's no refueling process, it's easier to license that way. The interesting part about this is that we actually would probably only need a couple people on site while the reactor is running, and the reason for that is because obviously we need someone for physical security and maybe a mechanic on site who can just do some sort of physical intervention to modify the mechanical equipment.The way these will likely work is that you'll have a central location where it monitors the behavior of dozens of reactors that are deployed at any one time. And you have all your nuclear engineers and your operators in that space and they monitor everything.So you don't need a nuclear engineer at each site. And that way these things are very deployable and, to be honest, everybody who's going to work on these things are going to be quite bored. There's not going to be a lot to do because reactors are mostly self-regulating systems, and the intervention that's needed on a daily basis is very minimal. So even for the hub, it's mostly just an observation exercise to check on transient behavior as it's operating and then maybe some tweaks here and there, and that's essentially all that would need to be done for these things. And then you can bring down your OpEx costs very considerably.So just a bit about the technology itself: You're working on two different reactors? Can you explain the differences in reactors and where they are in the development-deployment stage?We have two expert technical teams working on two different reactor designs, and that's partly so we can de-risk our own operations. So we know that even if one meets critical problems, the other one will be able to go on, so we're just doubling our chances of success. The MO we gave to both of them was the same: It has to be modular, it needs to be passively cooling, it needs to be able to be shipped anywhere in the world, so it needs to be fit within an ISO container. And we gave both teams that MO. They both came up with very innovative and novel solutions to that problem.So the Zeus reactor, which draws from the scientists and engineers down in California, their solution was just completely remove the coolants and use a thermal conduction. And if you do that, you can remove all the mechanical systems in the reactor. You reduce the size, you reduce the pumps, and then you have something that's very, very simple and size shrinks right down and you can get it in that ISO container system. That's very innovative, that's the Zeus reactor.The Odin team, their solution was, “Well if you could introduce some initial heat into the system for a salt-based system and the uranium is providing that natural heat, and you create a natural circulation so you can remove pumps and you can remove circulatory systems and that way, again, you can shrink the reactor right down.”So two very different solutions to the same problem, and that's how they differ. Odin does have a coolant that has a natural circulation that moves it around and Zeus has removed the coolant completely, which is more novel, I would say, and relies on a thermal conduction mechanism where the uranium just gets hot and it conducts through a solid core to the periphery where heat just gets removed by a naturally circulated air just going around.Is there a difference with how much power each kind could potentially generate from a shipping container sized unit?There was, originally, but I think the constraints of having to confine it to a shipping container almost got them into the same ballpark. So they're now both about, well, I'd say Zeus is maybe four megawatt thermal, Odin, it might be five megawatt thermal, but the power of the electric, once the conversion goes through, it brings them out to that one, one-and-a-half megawatt electric power output.And what can that power?A thousand homes for 20 years, mine sites, oil and gas sites for bringing the oil to the surface, remote communities, military bases…Plenty of power for that kind of thing.Plenty of power for that kind of thing. And also a big upside would be places where there's communities that completely are removed from the grid, desalination plans, medical facilities. Suddenly that all becomes very possible. You can unlock an enormous amount of wealth from landlocked resources, which just aren't economic because of fuel requirements to mine those things. So you can unlock trillions of dollars of value in resources just by having microreactors come into these remote locations. The industry environment (11:42)Whenever I talk with an expert about this topic, we eventually get to these two questions: One question is sort of, what is this technology’s timeline? So there’s that technology question. And then the second issue: What’s the regulatory environment like for you folks?You're going to see SMRs come online first. They're going to get licensed first. They've got a bit of a head start. Microreactors, at the moment, all of the main contenders, including us, are basically at the same point. We're going into physical and test work that's looking at about a two-year process to collect all the data and licensing. Licensing is actually the longest-lead item that's about just under four years. That takes us all out to about 2030 where, before you have a commercial deployment of a microreactor, you're able to go anywhere we want.I would imagine SMRs, it's going to be several years before that. But then once microreactors can deploy, you'll see many more of them being deployed than SMRs.Would they be regulated by the Nuclear Regulatory Commission (NRC)? Is that who the chief regulator is?Yeah, the NRC deals with all commercial ventures. So if it's defense or public, then you obviously would be DOE or DOD. NRC manages commercial ventures, so they're going to be in charge of the licensing for all micro and SMRs. I would say to your comment about the regulatory environment, I assume there are going to be adjustments made to the way these things are licensed because they are a very different product to a big conventional civil power plant, which is gigawatts or multiple gigawatts down to one megawatt. It's a very different device, very different operating system. I anticipate there will be changes. If there are not, that might complicate the deployment of microreactors.We do know they are aware of the need to modify the regulatory framework around these new systems. So we're hoping obviously in time for when we go to licensing process, and all the other microreactors are probably hoping the same, that that framework is in place so we can be assessed on their own criteria.The future of the microreactor (13:45)Are you viewing this as primarily initially as an American market or as a European market, as an Asian market? What do you see as the potential market for this? Once we're up and running,The first market will be the American market, and that's going to hit things like mining sites, military bases, data centers, AI centers, things removed off from the grid; but then you can expand very quickly in this state to something like charging stations for your EV vehicles in the middle of nowhere. If you bring diesel generators in to power those things, it defeats the point. And you can't just put wind and solar farms wherever you want because they're very locationally dependent on weather systems. But microreactors actually mean you can suddenly electrify the entire country. So you can periodically cite charging stations or EV vehicles throughout the whole country, and that'll be tens of thousands of potential essentially recharging stations that you can then drive your EV vehicle across the country because there could be periodic charging stations for all these vehicles. So it'll begin with that way.And we'll see a similar thing in continents like Europe that have more sophisticated grid systems. But then as this expands into places like Southeast Asia and Indonesia, the Phillippines, Thailand, big island community countries where microreactors are replacing diesel generators and making them more green. And then in places like Africa, large swathes of population cut off from grid completely, and then you'll see them deploying into those areas for desalination, medical facilities, and then ultimately mining projects.Big picture then, what’s the dream? What does the technology and the company look like in 2035 or 2040?So I would say 2035, what we want to do is we want to be really deploying thousands of these things across the world. Not just the States and North America, but internationally. There's essentially an unlimited market for these. We won't sell the reactors, but we will sell the power. So we'll be an operator for all these companies, industry partners, mining companies. We hope to be putting these things on ships and replacing bunker fuel and maritime vessels.We won't be hitting the main grid systems, exactly. I think SMRs will pick up a lot of slack there, but for the first time, we'll be in a position to really start taking our microreactors, and the cost of these things by 2035 will have fallen to such a point that they will be more economic than diesel generators in the middle of nowhere that rely on a constant importation of diesel and the associated costs with that, it could be very transformative. It could create an enormous amount of wealth, it could improve the health of the planet across the board, for locations that are cut off, cut off. And for NANO, I already believe we'll be a massive company anyway, but there'll be a lot of blue-sky potential for expanding into other industries.You're designing, you're developing, would you be the manufacturer, ultimately, of these reactors?Yes, we'll be the manufacturer of these things. As I mentioned though, we won't sell them because people won't be interested in a big upfront capital cost with the associated operating liability. So we will just sell power. You need 10 megawatts for 20 years? We’ll supply that. You need 16 megawatts for five years? We'll supply that, too. And that'll be the business model.Faster, Please! is a reader-supported publication. To receive new posts and support my work, consider becoming a free or paid subscriber. This is a public episode.
