There is the mitigating factor though that the engine is likely to be a lot higher efficiency, running straight off electricity, rather than having to burn fuel to release thermal energy and then using the expansion of gases to drive the piston, so less thermal energy should be wasted, so it may not be quite as high as that if you use the effective energy in 30kg of petrol.
it says that if the engine is allowed to actually accelerate, it consumes energy from the cavityHowever, it talks about hovering
Surely for one to be hovering on the other, it would have to be constantly accelerating to overcome the acceleration due to the force due to gravity? If I'm wrong, please say:). Woo, my first post on Slashdot...

Okay, there should have line breaks there ... didn't realise that they needed to html coded in.
