Proud to have made history with the team at @RainmakerCorp. This spring at @DiscipulusVent, I met @jared_western. Spent two hours at a party with him going deep on waste-to-energy. By the end of the week I knew I was leaving SLC. Since high school I've been obsessed with one question: why can't we turn our waste into cheap fuel? This summer I get to answer it — building the physical intelligence layer at Western Chemicals in El Segundo. Western deploys duckweed to wastewater plants and converts the output into fuel cheaper than trad petrochem processes. Looking for housing in the LA area, ideally close to the refinery. DM if you have leads.

@tsungxu @packyM Another unlock here in the future is when micro reactors become the norm how many remote locations are also unlocked. So much space available here on earth that’s hard to get to and provide power, but when those things change, so much can happen.




Overheard in Silicon Valley: "Rebranding to 'forward deployed engineer' from 'consultant' one of the great all time recruiting whammies."

GLP-1 drugs are one of the fastest-growing pharmaceutical markets ever. This startup is building the autonomous factory to produce them at scale. Founded by @RoMcLocko and @RodrigoCorEst, part of the @DiscipulusVent Spring Cohort.

Rainmaker’s @ADoricko says 10x’ing cloud seeding operations in Utah could accelerate refilling the Great Salt Lake, and he’s aiming to bring the Colorado River back to 1920 levels by 2031: "We have operations for the Bear River, which is the primary tributary into the Great Salt Lake right now. If we were to 10x our operations, we could radically accelerate the timeline for reversing the eradication of, and refilling, the lake." "We might get to see some participation at the federal level in cloud seeding because it's the only way to produce net-new water for the lake. That's an interesting project not just because the lake is a piece of national American heritage, not just because it's something that the ski industry in Utah depends on, not just because if the lake aridifies you end up with toxic arsenic getting kicked up like in the Salton Sea, but also it's the training wheels for what an interstate weather modification project would look like for the Colorado River." "Rainmaker's goal, to call a shot publicly, is to get the Colorado River back to its 1920 supply levels by 2031. That will mean about 8 million more acre-feet of water down. A lot of that will come from cloud seeding, and some of it will come from other technologies we're looking at right now."

It's unambiguous. For civilization to advance, we must scale three pillars in abundance: water, energy, and housing. The framework for producing homes and electrons has long been feasible, limited only by permitting and labor. But there has been no technology to produce water at scale in the interior of our country… until now. Rainmaker is the first company to operationalize cloud seeding and decentralize water infrastructure in America. Through unambiguous evidence of augmented snowfall, we have proven the path to scaling one of America's most scarce and necessary resources: water. We have not eased drought. We have not produced water in mass. We have not brought abundance to the West… yet. The job's not finished. But our team's relentless effort has produced a clear roadmap to achieve that vision, a clear roadmap to abundance. Thank y'all for supporting our team and our mission.
