  1. Today, exploding demand for power-intensive AI applications provides enough of an upside to justify producing components in space, providing the economic engine necessary to justify and fund the trillions of dollars necessary to build and sustain space factories.

  2. Starship can lift orbital power generation to about 100 GW with perhaps 10,000 launches per year, or about one per hour.

  4. The only highly populated industrial country unable to trivially meet its electricity and synthetic fuel needs with solar alone is the United Kingdom, due primarily to a high population density and high latitude. The Nordic and Baltic countries are tiny by comparison. Among other problems, the UK needs to decide if it wants the future where energy is cheap and it is rich, or the future where energy is expensive and it is poor. If the former, it is time to get serious about large scale deployment of wind power, using home-grown vertically integrated technology at prices as low as $10/MWh.

  11. I would never like hold up a flag saying I'm really good at building highspeed trains. Like that is just a sign that you're really bad at capital allocation.

  12. They're focused on the chips, right? Because they understand like the key bottleneck is the chips, not the solar power, right?

  13. you're going to have to build your own power plant for them, which is how it used to work. Like if you if you had an aluminum plant back in the day, you would be building your own power plant for it as well.

  14. It is not only the case that solar adoption, production, price decreases are continuing. They're accelerating. And the rate that they're accelerating is still accelerating.

  15. actually it turns out that you can significantly decrease power consumption with a very small reduction in overall compute. So if you if you've got like three really bad days in a row or something, you can actually just like you can dial back your power usage quite a lot without compromising your inference or or um or training.

  16. You can revisit a bunch of legacy industrial processes that are have been optimized for efficiency and say, well, what if we just like use twice as much power and we just want to do them faster and cheaper, right? Like less capex, less lead time, more power, right?

  21. A battery that’s discharging every day gets great utilization, but one that’s only there in case the sun doesn’t come up for two days in a row, barely gets used.

  25. Yet solar development is hopelessly snarled by dozens of different development regulations which begin with the assumption that it will permanently and severely harm the environment unless proven otherwise, at exhaustive length.

  27. Per doubling of production, costs have fallen a consistent 30-40% since 1970, but it’s only in the last few years that this price has become competitive with legacy electricity generation

  28. we will see batteries aggressively displace transmission as the most cost-effective way to ensure continuity of electricity supply, leading to an eventual pruning of the grid and drastic reduction in the average distance that power travels between production and consumption, even as the average time that power is stored increases.

  29. The default climate discourse in recent years has been congruent to an acceptance that curtailing CO2 emissions would require the regrettable but ultimately impersonal de-industrialization and re-impoverishment of most of the world, which is both morally repugnant and politically impossible to achieve without first use of nuclear weapons.

  30. Following current trends to second order, >95% of humanity’s energy needs will be downstream of solar panels by 2042, just 19 years away, and alongside enormous expansion in direct use of electricity, fuel consumption will grow to more than $25T/year in equivalent dollars.
