#218 Building THE Global Climate Collaboration Community & Lessons from the 00's Tech Boom | Duncan Logan (9Zero)
This is a free preview of a paid episode. To hear more, visit cleantechies.substack.comToday we are joined by Duncan Logan, CEO & Co-Founder of 9Zero. A community platform to bring climate professionals together in person and online so we can work together to solve the climate crisis. Duncan previously founded RocketSpace where he saw many tech startups that would go on to become unicorns. Companies like Uber, FlexPort, and Spotify. Having this experience made him realize the importance of creating a hub for people to collaborate and bump into each other. They are extending this even further by building these hubs in all major climate cities because unlike the 2000’s tech boom, there is no one silicon valley for climate. We need to connect NY, DC, Boston, Houston, London, Berlin, SF, Seattle, and beyond. Duncan brings a lot of experience and some great stories (like the time he met Elon). Check out the episode today.

#215 Decarbonizing Mining, Microbes x Metals, National Security x Climate, & the Microbe Mafia | Liz Dennett (Endolith)
This is a free preview of a paid episode. To hear more, visit cleantechies.substack.comToday we have the opportunity to interview one of the most energetic and inspiring people in climate tech. Liz Dennett, the CEO and Founder of Endolith. If you recognize the name Endolith, it may be because we had Moji Karimi of Cemvita on for episode 200. Endolith recently spun out of Cemvita to form its own independent company. They are solving a huge problem in the electrification puzzle — copper extraction. By 2050 we will need more copper than in the history of mankind due to the electrification of industry and developing countries. If we don’t solve this, it could lead to geopolitical conflicts. Endolith’s technology uses microbes to eat crushed rocks and poop out copper (I mean, I did say explain it to me like I’m 5). They add this to existing mining operations to increase output by ~10%. Solving this problem will help us get closer to meeting the rising copper demand. And this is a good thing for many reasons. Not the least of which is, as countries gain reliable access to electricity, women and children are the primary beneficiaries. That’s a world I want to work for. In today’s conversation, we’ll cover:* The role of copper in electrification* Her journey to CEO of Endolith* Why copper could be the thing wars are fought over (not water)* The innovation behind microbial mining* The balance between generating hype and focusing on scientific advancementsLet’s dive in.
