Aether Diamonds: Ryan Shearman
“I like to say we’re not a mission driven company. We’re not a company with a mission. We’re a mission with a company.” -Ryan Shearman, Co-founder and CEO of Aether Diamonds@RyanShearmanNYC, Co-founder and CEO of @AetherDiamonds, a startup creating the world’s first positive-impact diamonds. Ryan Shearman is a mechanical engineer turned entrepreneur. Early in his career, Ryan joined David Yurman as one of the first hires on their new Men's team, where he was responsible for overseeing the development of some of the brand's most iconic and commercially successful collections at the time, shipping over $80M worth of product in under three years. In 2013 Ryan founded his first startup, Fusar, a direct-to-consumer brand that developed tech-enabled safety products for the motorcycle market. Ryan currently serves as the founder and CEO of Aether, where he combines his passions for technology and jewelry with his personal mission to help solve the climate crisis. In his free time, Ryan can be found riding his motorcycle, teaching his dog new tricks, and spending time with his family.

Visit https://www.patreon.com/ctc1Enjoy the show!🤝 This episode is brought to you by ☀️Yotta Energy ! We all know energy storage is key to deploying renewables at scale. I’ve seen many energy storage solutions for commercial buildings over my years in climate tech, but none as impressive as Yotta’s. Yotta Energy’s unique "PV-Coupled" ecosystem of solar+storage solutions simply integrates within the standard solar installation process. Even better, their integrated storage technology can enable up to 60% more solar to be deployed on commercial buildings. With commercial buildings consuming 35% of US electricity that means Yotta is making a serious dent in CO2 emissions. With the electrification of everything revolution underway, Yotta Energy is poised to meet the growing demands of electrification by sizing solar+storage resources to recharge electric vehicles as they future proof buildings into distributed energy sites powering the grid of the future.

Dandelion Energy: Kathy Hannun
“How is everyone not working on climate change?...In my understanding of the science, I would say it will define the lives of people in my generation.” -Kathy Hannun, Founder and President of Dandelion Energy@KathyHannun, Founder and President of @DandelionEnergy, the largest residential geothermal company in the United States. Before founding Dandelion, Hannun was a Rapid Evaluator at X, Alphabet’s innovation lab, where she focused on finding “Moonshots”. Kathy initiated Dandelion as an X project and then launched it into an independent startup company in May 2017. Dandelion has since raised millions in funding from top VCs, set a new standard for geothermal quality and cost-effectiveness, and empowered homeowners to avoid over 100 million pounds of carbon emissions and counting. In February 2021, Dandelion raised a $30MM Series B funding round led by Breakthrough Energy Ventures.

Gradient: Vince Romanin
“If the next 4 billion ACs are all heat pumps, they can also decarbonize heating while we’re expanding access to AC. If they have low carbon refrigerants we can solve the refrigerant problem. Lastly, if we make sure they’re all smart and WiFi connected we can help modernize the grid at the same time and have more solar and wind on the grid.” -Vince Romanin, Co-founder and CEO of Gradient. Vince Romanin is the CEO of Gradient (@GradientComfort), which is on a mission to cool the world sustainably. Gradient plans to achieve this by increasing the efficiency of heating and cooling systems, removing harmful refrigerants, and electrifying the heating sector, all of which combined can offset about 2 GtCO2/year, or 7% of our total emissions today. Gradient’s first product is an easier-to-install and easier-to-use heat pump that is quiet and gives you your window back.As always, HUGE shout out to Climate Tech Cocktails official sponsors ☀️Yotta Energy and 💎Aether DiamondsAlso a BIG shout out to Climate Tech Cocktails’ first official SUPER Climate Warrior patron supporter, Extreme Tech Challenge! 👀 Want to learn more and be listed here?!?

ClearFlame Engines: BJ Johnson
“Globally we’re emitting about 5 Gigatons of CO2 from Diesel engines every year...so you’re looking at about 15% total emissions coming from that fuel in particular.” -BJ Johnson, Co-founder and CEO of ClearFlame Engines.

Wild Earth: Ryan Bethencourt
“The more I looked into it, the more broken the pet food industry was.

MicroByre: Sarah Richardson
“We need to make poop the new gold. We need to give new ways for poop to become the input, and for antibiotics to become the output...or for polymers or for bioplastics to become the output. That just means cozying up with bacteria, because they can do it.” -Sarah Richardson, Co-founder and CEO, MicroByreSarah is a computationally inclined microbiologist and science communicator: she speaks charmingly to computers, bacteria, and people. Sarah grew up in West Baltimore, and after completing a PhD in human genetics and molecular biology at the Johns Hopkins School of Medicine and a Postdoctoral fellowship at Lawrence Berkeley National Laboratory, Sarah founded the biotech startup MicroByre (@MicroByre), where she leads a skilled and diverse team in the construction of genomic toolkits for non‐model prokaryotes.

Air Protein: Lisa Dyson
“Right now the process is so inefficient to make a steak. It takes two years to make a steak and the greenhouse gases from a cow is equivalent to a car. So it’s hugely more inefficient than it needs to be. It’s way past time to be redone, for us to figure out new ways to do it. We’re focused at Air Protein on making meat in a matter of hours and not days. Making it using the most sustainable processes on the planet. Making it highly nutritious and of course still delivering the flavors that my husband, a meat eater, wants to experience when biting into a juicy steak. ” -Lisa Dyson, Founder and CEO, Air ProteinLisa Dyson is Founder and CEO of Air Protein (@AirProtein). Air Protein is a Bay Area based company that is working to reverse climate change and address food scarcity by making meat from elements of the air. Using a technology inspired by NASA, Air Protein makes the world's first air-based meat - using less land, water and other natural resources for the most sustainable meat on the planet. Lisa has a PhD in Physics from MIT, and was a Fulbright Scholar at the University of London, where she received an MS in Physics with an emphasis in Quantum Fields and Fundamental Forces, and has degrees in Mathematics and Physics from Brandeis University.

Aionics: Austin Sendek
“Spotify tells you the music you’re gonna like, Amazon tells you stuff you’re gonna buy, Netflix tells you which movies you’re gonna watch. All this is doing is saying ‘Hey, scientist, you tried these things and they didn’t work, you tried these things and they did work, here’s something you probably never would’ve thought of, but we think it’s gonna work.” -Austin Sendek, Founder and CEO, AionicsAustin Sendek (@BatteryCowboy) is the Founder and CEO of Aionics (@AionicsInc), a Silicon Valley startup that is leveraging the power of A.I. to accelerate the development of new materials for a zero carbon future. Austin is widely credited with leading the first successful demonstration of A.I. outperforming humans in the design of new battery materials, which he led while he was a doctoral student in Applied Physics at Stanford University. His research publications have been cited over 1,200 times, and he was included in Forbes Magazine's 30 Under 30 in Energy list in 2019.
