Air-powered car?
Rave Racer (and you guys were giving me shit about not using my real name
10 years ago) is correct here though, using easily accessable "free"
energy like Solar, this motor could be quite efficient. Biggest
maintainance item I could see would be the air dyers needed so the tank in
the car wouldn't rot. Someone like me that lives in a very dry climate,
and very sunny, could have a very simple closed system with solar panels
on my garage, and never have to pay for gas again (bonus, you could run
your air tools for "free" as well).
I wonder, couldn't a smaller version of his engine be run in reverse as a
compressor? Piston comressors are very inefficient and require a decent
amout of electricity to run.
Hell, you could even design a "hybrid" style system with a small comressor
reclaiming lost energy from coasting and braking.
Regardless, if done properly, this is a MUCH safer, and *possibly* more
efficient system than hydrogen (fuel cell or piston engine).
Ok enough rambling, lets just say its something interesting, and I'd like
to know what kind of real power he is getting out of these motors, at what
PSI and CFM.
