Understanding how Tesla did it

[emanresu]

"Lifting the mass requires work (energy * time) to be done. Holding it does not. It is only a force and a piece of wood can replace your muscles. Where then does your energy come from?

Remember energy = force * distance the mass moved, and work = energy used to move the mass * time it took to move the mass.

Our arms are obviously doing work when we hold a weight at a height - you're saying that say a shelf isn't?

Have scientists proven that heat isn't produced in a shelf by a weight applied to it?

Our arms are very inefficient so we shouldn't make a direct comparison between them and a shelf. We should ask how many degrees Celsius can we raise a shelf per second with the energy of a force of 1N? How fast will this heat be dissipated? Have experiments actually been conducted in this area?

It could also be converted to a frequency that we cannot yet measure or officially tap.

As for the work function - it isn't even a model, it's just a rule to determine the energy required to move an object against an opposing force, in this case gravity. Certainly it shouldn't have authority over theories about objects at rest and under the specific phenomenon of gravity. Neither does the fact that gravity is just a force mean that in reality it conveniently turns on and off as it does on paper.
