[SpaceProgram] Seasteading crossover options

A surface/ground system could be partially closed at lower cost than a submersible or space system
good way to do some testing.
the submersible would provide stricter testing parameters with bigger failure costs (eg death) similar to space

Now an amphibious RV... hmmm

wasnt there some TV show way back in 70/80s about a bunch of space types (or Armageddon survivors or both) driving around in an RV-type setup?

Not only would it be quite cheap to put together from the ground up, but it could be moved around easily for collaborative and experimental purposes ... There is lots of crossover here with various sustainable living research areas, so it could be a very useful and low overhead way to get something hackerish going ...
