Lightship Co-Founder and CEO Toby Kraus
One in ten American families own a Recreational Vehicle, and yet, the RV industry hasn’t seen meaningful innovation in decades, due in part to extreme consolidation and lack of competition. Despite this, 300-500,000 RVs are sold in the US every year, 90% of which are towable. Towing an RV can seriously affect the fuel economy of your car. Drivers can expect their gas mileage to decrease about 1-2% for every 100 pounds they tow. The average weight of a large travel trailer is about 6,700 pounds, which means a driver can expect between a 49-74% decrease in gas mileage. This means more stops, more money spent on gas, and more emissions.On top of that, most RVs use propane to fuel generators, which in turn power appliances or amenities, making what should be a peaceful experience outdoors noisier, and the cost of an RV trip even higher, both for a family’s wallet, and for the planet. If you drive an electric car, towing a RV means an extreme reduction in range and therefore an increase in charging stops, which is a challenge for people adventuring in areas without charging infrastructure. As the US races towards electrification, more and more people are opting to buy hybrid or electric vehicles. But, for the one in 10 American families that own an RV and may be looking for a better, or even electric, RV experience, they are in serious need of options. So, in order to electrify the RV industry, and bring automotive electrification to a new segment, we need a solution that is lightweight, super aerodynamic, and above all, fun. And that is exactly what Toby Kraus, and the team at Lightship, are building.

Heirloom Co-Founder and CEO Shashank Samala
Even if all emissions stopped tomorrow, the excess carbon currently in the atmosphere would take thousands of years to naturally dissipate through processes like photosynthesis, oceanic absorption, or mineralization. In addition to forests, soils, and the ocean, naturally occurring minerals are one of our planet’s most important carbon sinks. Over the span of hundreds or thousands of years, carbon dioxide in air and water binds to minerals, and eventually turns to stone, thus removing the carbon from the atmosphere. This process is called mineralization. One of the most abundant types of rocks on the planet is limestone, and it’s one of the unsung superstars of this carbon mineralization process. Meanwhile, one of the most exciting advances in the carbon removal industry that has received a lot of attention - and scrutiny - is Direct Air Capture, often referred to as “DAC.” DAC is the process of separating carbon dioxide from ambient air. The Inflation Reduction Act and Bipartisan Infrastructure Law specified funding for the deployment of DAC projects in the US, and DAC is getting more interest from companies looking to remove their carbon emissions. But, DAC technologies are typically expensive, energy and land intensive, and use materials that can be difficult to source. In order to remove billions of tons of carbon from the atmosphere, we need a DAC solution that is scalable, inexpensive, and designed to leverage natural processes like mineralization via limestone, which has millennia of carbon removal capabilities embedded in its chemistry. And that is exactly what Shashank Samala, Co-Founder and CEO of Heirloom, is building.

Odyssey Energy Solutions Co-Founder and CEO Emily McAteer
According to the World Economic Forum, if we want to reach a carbon-neutral future, the world will depend on emerging markets to build energy systems that rely on clean energy instead of fossil fuels. However, only one fifth of global clean energy investments are being channeled into emerging markets. Financing the development of distributed renewable energy projects has been slow and challenging for interested investors and project developers. In order to facilitate the growth of distributed renewable energy in emerging markets, and connect financiers, equipment providers, and project developers who see the immense opportunity in decarbonizing growth in emerging markets, we need a platform where all stakeholders get what they need to finance, build, and track the performance of these projects. That’s exactly what this month’s Watt It Takes guest, Emily McAteer, co-founder and CEO of Odyssey Energy Solutions, is building. At Odyssey, Emily and her team are building a new kind of platform to make it possible for distributed renewable energy projects to launch in emerging markets, by connecting financiers, equipment providers, and project developers, and providing the remote monitoring and control needed to assess performance.Emily joined the podcast to speak about her journey from Concord, Massachusetts, to working on Wall Street, to the lecture that would change her life, to founding Odyssey and building a platform that’s responsible for the deployment of ~ 2.5 million standalone solar systems and positively impacting the lives of 15 million people.

Commonwealth Fusion Systems Co-Founder and CEO Bob Mumgaard
According to researchers around the world, fusion could be a nearly waste-free, carbon-free, and all-geography answer to creating enough dispatchable power to get us through the energy transition. To achieve this, all components of a fusion power plant need to be built so that when fusion energy becomes a reality, we have the industry, infrastructure, and processes in place to distribute the power, and it has to be cost competitive. This is exactly what Bob Mumgaard, Co-Founder and CEO of Commonwealth Fusion Systems (CFS), is building. Today, CFS has more than 600 employees, has raised $2B, and is executing on their plan to make the “holy grail” of fusion energy possible. Guest host Lara Pierpoint sat down with Bob to learn more about his journey, the CFS story, and the work being advanced by his team.Sponsors Watt It Takes is brought to you by Shell Ventures and SPAN.Shell Ventures specializes in unlocking deployment opportunities to help their portfolio companies scale, access customers and commercialize their solutions.

Petra Co-Founder and CEO Kim Abrams
Climate change-fuelled natural disasters and vulnerable transmission infrastructure have defined some of the worst natural disasters of the past decade, including the 2020 wildfires in California. It’s clearer than ever that in high-risk areas, above-ground transmission lines need to be dug underground to protect communities from fires and to ensure their access to electricity in the face of increasing natural disasters. And that’s exactly why this month’s Watt It Takes guest, Kim Abrams, founder and CEO of Petra, is building a trenchless digging platform to make undergrounding utilities easier and more cost-effective. Today, Petra has 72 employees across multiple continents, has raised $45M, and is winning contracts to underground transmission in the US and Colombia.Guest host Lara Pierpoint sat down with Kim to learn how they're enabling utility undergrounding, more about their trenchless technology making it all possible, and the story behind how she founded Petra.Watt It Takes is brought to you by SPAN.SPAN are the makers of the award-winning SPAN Panel—a smart electrical panel that enhances how homeowners interact with their energy.

Lunar Energy Founder and CEO Kunal Girotra
From induction cooktops and heat pumps to the rooftop solar needed to power it all and the batteries to store excess energy for use during blackouts, we’ve had incredible success building the tools we need to decarbonize our homes. But to the regular consumer, the universe of electrified solutions can be overwhelming. What we need is a home battery system and an integrated ecosystem of all electric products to make it easier than ever for homes to switch from gas to electricity, alongside software solutions to help manage residential energy production, storage, and usage. And that’s exactly what this month’s Watt It Takes guest, Kunal Girotra, Founder and CEO of Lunar Energy, is building.Lunar emerged from stealth last year with $300M in funding from SK Group and Sunrun, now has 250 employees, and publicly unveiled their integrated residential energy product last week.Emily sat down with Kunal to learn about how they're building the future of residential electrification, his journey from growing up in India to leading energy at Tesla, and the story behind the growth of Lunar Energy.Watt It Takes is brought to you by Shell Ventures and SPAN.Shell Ventures specializes in unlocking deployment opportunities to help their portfolio companies scale, access customers and commercialize their solutions.
