>Hilmar, in one breath you are saying that "You don't need energy simply to maintain a force" which is over unity, then in the next breath you saying it is not possible, please get your facts straight.

Probably the best example I can give is running a low speed diesel main engine for prolonged periods (more than 1 minute) within one of it's critical speeds, the resulting harmonic amplification can result in the total failure of the engine i.e. the shearing of a 36" Diameter 100 Ton steel Crankshaft Journal.

Without having read all of this thread, it looks like there's some commingling of the concepts of force and energy happening. Shearing of a shaft requires force. Forces within the engine are the result of its extracting energy from supplied fuel. Harmonic multiplication of such forces is a well-understood phenomenon, and, as you've pointed out, can result in spectacular failures.

My understanding is that propellor cavitation damage is caused by sonoluminescence, the effects of which have been understood for some time now: http://en.wikipedia.org/wiki/Sonoluminescence . Fundamentally, this is another example of harmonics/resonance.
