Hi Guys,
I remember years ago Kitplanes did a series on the potential for
batterry-powered aircraft. Recently, I watCHED Future Cars on the
Discovery channel and this guy had developed a car that ran on
compressed air. This seems like a more viable fuel for aircraft then
batteries. Has anybody looked into it?
just curious.

You ned either:
1. a very long hose attached to a compressor or

2. a filament-wound balonium/unobtanium air tank filled with air
compressed to 100,000,000 psi.

Otherwise, you just can't carry enough compressed air around to make a
practical vehicle.

The "Future Car" ranks right there along with Moller's "Skycar," in that
it is all vaporware.

Ah yes the "Skycar" Seems he has given up trying to scam people with
that. He is now touting it as a Ground Effect vehicle and still
showing it in operation on the tether only. A long thread is
currently running in rec.aviation.homebuilt.
