    🚨 SPECIAL EP: #173 Breaking Down GGRF and $20B into ClimateTech w/ Franz Hochstrasser (Raise Green, S2 Strategies)

    🚨 SPECIAL EP: #173 Breaking Down GGRF and $20B into ClimateTech w/ Franz Hochstrasser (Raise Green, S2 Strategies)

    The Greenhouse Gas Reduction Fund (GGRF) is a generational government program deploying $27B into clean energy projects across the US. But what is the bill really?
    Franz Hochstrasser is an expert in financing projects in low-income areas and has a wealth of experience working on climate for the government - both of which are KEY for GGRF. 
    Franz started his career “giving his 20s” to the government, and with that doing some amazing work as the Special Advisor to the Special Envoy for Climate Change, Deputy Associate Director at the Council of Environmental Quality, and at the USDA.
    Since then, Franz founded Raise Green where he democratizes the ability to invest in climate solution projects. Through this, he is an expert in sustainable finance for inclusive growth and financing projects for low-income residents. 
    He joined S2 Strategies to navigate GGRF and other landmark legislative movements. And it was an absolute blast to have him on.

    #172 AI x Production, Learning from Tesla, Transitioning to Iron, Battery Technology & More w/ Vivas Kumar (Mitra Chem)

    Somil chats with Vivas Kumar, CEO of Mitra Chem,  the first lithium-ion battery materials manufacturer focused on shortening the lab-to-production timeline by over 90%, addressing the largest barrier to innovation: R&D and scale-up speed.
    Vivas was a phenomenal orator and if you take a second to learn about Mitra Chem, it’s easy to see why. By combining their knowledge of iron-based cathodes with an AI and data enhanced production capacity, they are able to manufacture quicker and more reliably than many of their competitors. 
    As always, thanks so much for listening and enjoy the episode!

    #171 Regenerative Farming, Carbon Credits, Smallholders, Global Protocols & More w/ Josh Knauer (ReSeed)

    In this episode, Somil chats with Josh Knauer, CEO of ReSeed, bringing carbon credits directly from farmers to the market.
    They focus on the oldest form of carbon capture – vegetation. They support farmers in taking their protective and restorative farming practices, validating them, and then creating the mechanisms to sell those credits to interested parties. 
    We talked about:
    His strategy to differentiate these credits compared to the rest of the market, What works for them, How he’s building an entire protocol around these methods, What he’s learned from engaging with smallholder farmers,Why ag may make the best nature-based solution to carbon capture, As always, thanks so much for listening and enjoy the episode!

    #170 Computer Vision x AgTech, Precision Spraying, Herbicide Usage, & More w/ Tom Gauthier (AgTechLogic)

    #170 Computer Vision x AgTech, Precision Spraying, Herbicide Usage, & More w/ Tom Gauthier (AgTechLogic)

    Each year, about 1 billion pounds of chemicals are sprayed on crops in the US alone - globally, that number is around 5.6 billion.

    Our guest today is AgTechLogic, and they are solving this problem.

    They do this by helping Farmers retrofit their existing machinery with precision sprayers that use computer vision to identify weeds and spray only on the weeds in a concentrated way that kills the weeds and won't overlap with the crops.

    Today, nearly all farmers use broadcast spraying, or spraying everything. By implementing this tech, farmers can save a lot of money and produce healthier produce.

    Let's get into it. 🌱🌎

    #169 Urban Mining, Solar Panel Lifespan, End of Life Engineering, & More w/ Adam Saghei (WeRecycleSolar)

    Are you curious about what happens to solar panels when they are no longer usable? Maybe your crazy uncle's statements from last Thanksgiving about how solar doesn't work are still echoing.

    Well, look no further. Today, we are speaking with Adam Saghei, Founder of WeRecycleSolar, and we are discussing the end of life for solar panels.

    How circular can we make the supply chain? What can OEMs learn about their products' end-of-life? What is the REAL lifespan of a solar panel? How is this reality affecting investor returns? How are solar panels being refurbished and resold? And how are investors getting early upgrades to make a higher return despite the additional capex?

    Let's get into it. 🌱🌎
