There are two ways to improve space access: 1. kg to orbit - make it cheap to put more up 2. m3 in orbit - compile matter on top of Earth’s gravity well For the latter, satellites and compute don’t need to be overbuilt to survive a strenuous launch. 10x better mass efficiency.

sci fi monuments to human ingenuity spotted between las vegas and LA. 3 solar thermal towers, 386 MW, built in 2013. 173,000 rotating mirrors concentrating max sunlight on each tower to boil water, the steam rotates a turbine, driving magnets that push a lot of electrons. cool idea. awesome aesthetics. but the tech branch was pruned by plummeting PV costs, outcompeting the unit economics still, love to see a desert cathedral in the form of an artificial mega-sunflower, even if the noble idea didn’t quite win
