I have been considering a variety of ways to experimentally verify the operation of a gravitational field power generator by coming up with different ways to destroy or break the device.
Let's assume that we use mechanical force to squeeze together the similar poles of two bar magnets, and then we leave the device to sit in this uncomfortable position. Stress should build up, and eventually the arms on the device should either shatter or bend. However people would insist that the energy used here was the result of the mechanical energy input at the beginning.
Therefore I have concluded that it might be best to design the device with rugged materials, that will not break, and then to make sure it doesn't break, ease up a little on the pressure. The device could then be used to heat water. Perhaps after the device has warmed water for about six months people might start to wonder about where it was getting the energy it was using to heat water. It could not have been the mechanical energy involved in the beginning, when the arms were forced together, because the arms have remained forced together, so that energy is still locked up in the system. This test is so low tech that some guy could do it in his garage.
Let's suppose that we were to call in reinforcements (quantum forces) in the form of extremely heavy suspended weights being held aloft by the force field generated by the two similar poles of a powerful magnetostatic field (such as powerful bar magnets). I prefer to think of using bar magnets because then there is no other power source involved in generating the field and the source of the energy generated becomes more readily apparent, although it would also be true that if the energy generated was greater than the energy input to maintain a generated magnetostatic field, then obviously energy was being generated by the device. The bar magnet is just a more dramatic demonstration of the concept.
In the field between the two heavy weights we have our generator, which might turn out to be some kind of electromagnetic turbine. If we were to suck all the energy out of the field would it not be the case that the massive suspended weight above would crash down and destroy the device (it is for this reason that we begin to consider the addition of hydraulic suspension).
However, if we were to suck out only a percentage of that energy would it not be the case that the force field would become weaker, and the distance between the two heavy weights would only decrease, while at the same time the heavy weights would remain suspended?
If we were to suspend weights using bar magnets of different strength, while keeping the weights constant, would it not be true that the distance between the suspended weights would be different and dependant upon the strength of the bar magnets? This then leads us to wonder where the source of the power is that the bar magnet is employing so as to suspend these weights and hold them aloft in an anti- gravitational field, because it would be apparent that a constant replenishment of energy would be required by the bar magnet to compensate for the constant downward momentum being generated by g-forces.
This leads me to draw the conclusion that if energy was drained from a magnetostatic field the magnetostatic field would be required to replenish this lost energy resulting in a constant cycle of energy transfer.
