Life gets infinitely more difficult and infinitely more rewarding when you come to be a respecter of outcomes.

Who do I need to talk to help build racks for these?
Elon has unveiled the names of @SpaceX’s two new supercomputer clusters that are coming soon, which will bring online an additional ~$35+ billion of GPUs:
• Gun Range: Late November
• Spam: December
That’s ~420,000 Nvidia GB300s GPUs between them. SpaceX is absolutely COOKIN’ with how quickly they’re putting up these new clusters.

Pumped storage stations use up to 30% more electricity lifting water than the water gives back on the way down.
Bath County, Virginia, exists to move power across the day all the same. Pumps lift water to the upper reservoir at 12.7 million gallons a minute when demand is low. It comes back through six turbine generators at 13.5 million a minute when demand rises. That drops the upper reservoir by as much as 105 feet.
Bath County entered service in December 1985 and its 3,003 MW make it the largest pumped storage plant in North America.

ALT Cross-section diagram of the Bath County pumped storage station in Virginia, not to scale. An upper reservoir of 265 acres, behind a dam 460 feet high, connects through tunnels to a powerhouse with six turbine generators and a lower reservoir of 555 acres. 12.7 million gallons a minute are pumped up when demand is low, usually overnight (blue). 13.5 million gallons a minute fall when demand rises (red). The upper level moves as much as 105 feet and the lower 60 feet. Footer: 3,003 MW generating capacity, 750,000 homes it can supply, in service since 1985. Source: Dominion Energy.

In a world trending towards automation and AI everything, IRL experiences and relationships will matter more than ever.
I’ve learned that when you authentically do things that aren’t scalable, it can lead to great outcomes.

Robots Made in America
@sdianahu
Robot foundation models are starting to transfer skills from one machine to another, which means the bottleneck is shifting to hardware.
The U.S. still imports much of its robots and their critical components. We want to see founders rebuild that supply chain here, from magnets, motors, gears, and sensors to chips, batteries, and the machines that make them.

Three major announcements today:
1/ our first supersonic turbine core is complete and shipping to test
2/ our 2GW Superpower Superfactory in south Denver is already making parts
3/ we are building our own advanced all-digital foundry to make single crystal turbine blades

Lots of new followers, so I should probably explain what we're doing at @ValstadShip:
We're decomposing the common operations required to build ships, and building autonomous systems to carry out those operations at least 10x faster.
Let's make America competitive again.
