0II∞ has a website.
Over the late 2000s they sneered at "the odd billionaire", along with governments, having a monopoly on spaaace. Their plan was to raise a balloon and launch roggets thence. A successful test was had in 2017.
Balloon-to-orbit is the only way to retrieve a crew from Venus' 55 km altitude off that hellpit back into orbit and home. So this poast comes a little late in this blog's career. Sadly it remains ahead of any real implementations here over Earth.
0II∞'s Bloostar aimed for 70-100 kg payloads launched with methalox, like what the Raptor drinks. I'd mooted maybe something like spinlaunch for such dumb cargo although spinlaunch is a lot of overhead to "bloon" up to the strato'. A strato-runway might work for jet-to-orbit. To get real counterweight in 22 km, they'd likely need rotors wired to a modular reactor; but that's a problem for later.
It seems they shifted to tourism. For odd millionaires.
Maybe the issue was that they dreamt all this up back when the Merlin engines looked sooty and unworkable. The Merlin remains sooty, but the Falcon 9 works. Cargo-to-orbit is now a lot cheaper than was then envisioned. And the Starship is coming.
