Forget about the 'privatization' of NASA. Check out this idea for ways to make space travel cheaper:
The
shift to using private enterprise to economize space travel is of
course a good idea, but so far seems to overlook the central problem
with getting to space cheaply -- rocketry. Using a rocket to get into
space is simply too inefficient to be economical. Something like 2% of a
rocket is actual payload; the rest, fuel and associated hardware for
containing and harnessing the energy in said fuel.
The
trick, as it seems to me -- get the fuel 'off' the space vehicle. At
least for now, until otherwise radically different technologies become
available.
The thing I really like about this guy's
'sales pitch' is that he has a hard and practical goal -- get fuel and
supplies into space at about 90% less cost than presently feasible.
Nothing particularly 'sexy,' just a clear and useful goal that could
make a profit in relatively short order.
And he has a
fair amount of hard evidence and experience to back up the feasibility
his idea, not just theoretical calculations. Interesting.
Looks good to me.
ReplyDeleteSo many promising technologies. Hopefully one or more of them pan out before the next endarkenment.
