I don't hold any opinion so strongly that a good argument or better, 
experimental evidence, won't get me to change my mind.

I think something like this would be very cool, not to mention extremely 
useful.

I am not even welded to conservation of energy if anyone figures out how to 
get around it.

But if the device works as you indicate, how does it sense 
velocity?  Obviously you could get a lot more power out of a device going 
like a bat out of hell than one moving slowly.  So for higher velocities 
does it take more power to operate at constant thrust?  And in what 
reference frame?

Best wishes,
