Well I have been podering this whole move to hydrogen for sometime now and the technology is very cool and it is exciting how far we have come recently. Though currently the best way we have to get large amounts of hydrogen is to mine for natural gas as hydrogen is most commonly connected with natural gas. So this is my wild idea using technology I have seen in the news. On this planet we do not seem to have an efficient way of getting hydrogen which just happens to be the most abundant gas in the universe, right? Ahhh the universe that place outside of earth the place where only millionaire's get to travel. Now I am by no means a science guy but I read enough to get some general and creative ideas. More recently
Cosmos 1 was launched into space which, if successful, whould lead to fairly inexpensive space exploration. Well if beyong exploration it was used to tow/transport hydrogen from some gascious cloud to s storage facility where it may be compressed and stored possibly. The facility itself could end up being a joint venture between space agencies around the world and corporate america to get an international space station/hydrogen rig. Now the wild way to get it back to earth so it can be used, let us make use of that
space elevator in this case for space to earth transport. This is just some throughts on using information in the new how all this might be possible. Though a lot of this relies on strong and working developtment of carbon nanotubes which would be used for the cable, possible the sail, and maybe some system thats needed to absorb/get hydrogen. Well there's my crazy theory on that but I think it may be wholey feasible some day. I guess we will have to see what the future holds.
