Honored to write for @ASMEdotorg on how the legacy of the steam boiler helped inspire Boiler 2.0 and @AtmosZeroSteam's mission. Thanks to Louise Poirier, @JwintersA for their editorial support & the invitation. ♨️ Link in the following post -


Is decarbonization dead? @JaneAFlegal & I join @ezraklein to talk through how Trump just shredded America's most ambitious climate policy, what survived, and where we go from here. Listen @nytimes or wherever you get your podcasts. 🎁 link below.
Nothing says you believe in energy dominance quite like doing whatever you can to hobble investments in energy infrastructure. via @NYTimes nytimes.com/2025/07/23/cli…

This has long been a bipartisan view, that America can lead the energy industry and its transition to lower and lower emissions through innovation. Glad to see the team at Clearpath continuing to beat the drum.
American energy dominance is a phrase we hear often, one we like, and with the right strategy, it is achievable. The strategy in short: America should innovate, make energy here, and sell it globally. @TheNatlInterest nationalinterest.org/blog/energy-wo…
From a sketch on a whiteboard to an ETL listed product in the field. The leap from “zero to one”—from an idea in your head to a real product in the real world—is one that so few companies manage to make, and I’m so proud of our team for having gotten this far. Full Steam Ahead.


Surprised that the RETVRN conservatives didn’t coalesce in the name of preserving Western Culture and Classical Radio by pushing back against the rescission of funds for public broadcasting a bit more
The next clean industrial revolution could be just around the corner. If you are an ASME member, please check out “Full Steam Ahead.” magazine.asme.org/issues/july-20…
Some folks are still posting compressor test stands and glossy renders. We’re running an ETL-listed product in the field, making real steam for real customers. Call us when your “demo” leaves the lab.♨️ #heatpumps #climatetech #industrialdecarbonization
There has been a longstanding bipartisan consensus that funding basic research is a necessary investment in America’s economic future. This is breaking from that tradition and ceding future technological advances and industry to China.

THIS IS A BIG DEAL. It's many industrial policy financing tools in one transaction: preferred equity purchases, warrants, lending, and a price floor. And a staggering amount of money. But a few initial thoughts. 🧵🧵🧵
So proud 🇺🇸 MP Materials Announces a Transformational Public-Private Partnership with the U.S. Department of Defense – Multibillion-dollar DoD commitment – New “10X” magnet facility to be constructed – 10-year price floor + offtake agreements – DoD positioned to become MP’s…
Fart physics are more complex than contrail physics.
I wouldn't trust Lee Zeldin to answer questions about the physics behind farts let alone "chemtrails" (ie: water condensation)
Hot and sunny. Cold and snowy. Damp and cloudy. Boiler 2.0 doesn’t care. With the widest operating range of any industrial heat pump, it just keeps delivering steam. ♨️ #climatetech #heatpumps #industrialdecarbonization #electrification
Feels like YC is ripe for disruption and is becoming negative signal for founders with generational ambitions.
Surprising that this message is so triggering. Science, technology, and engineering are the greatest drivers of human flourishing. Calling on the most capable minds to build things civilization needs shouldn't be controversial.
It's pretty funny seeing Texans attack cloud seeding as 'playing god' My brother in Christ, this is Texas—we drill holes 2 miles deep below the ground, shatter the earth with explosives, then pump chemicals directly into it. Settle down, cowboy.
