Nothing wrong with the basic idea, but it seems to me that for the power required to collect and liquify enough gas to propel an aircraft for a useful period of time, and then heat a pellet bed to the point where you can make a gas rocket work (and KEEP it hot during gas flow), you could probably drive a wheeled rover about a couple of hundred miles.

Might be a solution in search of a problem.

  - A lot of prototypes look less than sophisticated. Not always something you can judge by. - Tom Brosz - 12/1/2004 6:10:25 PM
    - Not quite 13 micron (or whatever their down to now) (n/t) - RobVG - 12/2/2004 3:33:39 AM
