Every now and then I look at my latest model of a terraformed Mars. One of these days I'll get around to completing the enhancement down to 6 m resolution. In this thread I'll drop a few screenshots of my favorite places.

Water 💧 I always found this unbelievable, but there are 4 moons in the solar system with more water than Earth. One of Jupiter’s moons, Ganymede, has 26x more liquid water than Earth. Only 2% of the liquid water that is sloshing around on various worlds in the solar system

Anduril CEO Brian Schimpf: “The US capital market structure isn’t 10% better than anyone else. It’s several thousand times better.” Where else could you finance $200B of data centers with no revenue? If we can aim that financial engine at manufacturing and defense, America wins

It’s hard not to see an abundant future. A Cambrian explosion of nuclear energy. AGI. Autonomous transportation. Starlink. Cheap space launch. If you’re pessimistic, you will almost surely be wrong.

Electricity Demand - The Big Three The world currently uses about 27,000 TWh of electricity per year. There are 3 technological forces that are big drivers of growth for electricity demand. 1). EVs, electrification of all transport (cars & trucks) is going to require an extra

🚀 How to build a 12,000ft Ram Accelerator 🚀 Wouldn’t it be cool if you could launch stuff into space using liquid rocket fuel, but without having to lift the fuel along with the rocket? Well you can. (and no, not the spinny thing or the train track thing) You can totally

I present to you USAMACHINESHOPS.COM The fruits of my vibe coding labor. The impetus was receiving lots of recent requests for lists of machine shops. It's hard to overstate the value of a nearby machine shop partner you can trust. Many are difficult to find online and the

who’s going to make the motors, gears, bearings, shafts, machined parts, sheet metal parts, tube frames, molded parts, cast parts, printed parts, composite parts, springs, stampings, power transmission components, pcbs, electronic assemblies, wire harnesses, battery packs,

People of Twitter: If you're a propulsion/design engineer from SpaceX, Blue, or elsewhere who wants to work on advanced airbreathing jet engines, please DM me We need NX wizards who can own variable nozzle design, flameholders, and other fun mechanisms and subsystems

We have gone from 0 to 1 for thermodynamic computing. Now it is time to scale the paradigm. Excited for what the future holds.

Today, Valar Atomics became the first startup in history to split the atom. Announcing Project Nova, a series of zero power critical tests on Valar Atomics' Nova Core in collaboration with Los Alamos NCERC and NNSS. Nova went critical for the first time this morning at 11:45am.

Researchers at Tokamak Energy have captured for the first time a real-time, high-speed video of plasma behaviour inside their ST40 spherical tokamak, tracking visible green and red light emissions as the fusion process occurs. This visual insight comes via a camera operating

Side note, these are the exact same losers who lectured everyone after every SpaceX crash about why SpaceX needed to become more like Boeing and the ULA to succeed. Look how that turned out. They aren't just wrong, they are anti-right.

I will spell it out so everyone gets it: To win the AI race you need the most compute, data, and energy. Everyone is working within the same constraints: there's just one internet, just one GPU provider, same competition over data centers, energy suppliers, etc. Space changes

Rugged individualism is the path of freedom and prosperity, America proved it. Incremental improvements in services and distribution are essential to avoid catastrophic income inequality, absolutely. But you don’t kill the goose because not everyone gets the same number of eggs.

We're at this weird moment where the tools are way ahead of the security models. The capabilities are genuinely transformative. But we're basically winging it on the safety side. Don't use it carelessly. Run it on a dedicated machine. A cheap VPS, an old Mac Mini, whatever.

This is a great opportunity to point out what Classical Liberal Democracy really means, and how neither political party in the US today upholds its values. To start, Philosophical Liberalism is the broad moral and political philosophy that places individual liberty as paramount

I’ve been saying this for 10+ years: The reflex to brand innovation ecosystems as “Silicon [fill-in-the-blank]” (beach, slopes, hill, etc.) is lame, lazy, and dumb. Successful ecosystems are built around the unique combination of resources, talent, and culture that coexist in a

Great piece by Will Manidis , this bit in particular stood out to me: Simulation compresses whatever it can reach. Human effort migrates to whatever it can't. This is how it has always worked. It will be more true after AGI than before. [But…] Simulation has not exhausted
