The thing about thermodynamics

Stuff can never actually "stop", because another process is necessary to intervene. That process may simply take the energy out, but then you increase the entropy elsewhere, so system still has or increased the disorder.

If you wanted to reverse a process, you must stop it first because it is going one way. The laws don't change in reverse, but they have continue doing what they do unless you stop them.

The interesting thing about thermodynamics is that thermodynamics has to do with all the changes and differences in heat energy and work. 

It takes a difference in heat to make a heat engine. Hence, according to thermodynamics, there is no way of extracting work from a reservoir(s) with no temperature difference. 

0-point energy is the lowest energy quantifiable or simply the energy remaining after all possible energy is taken away. This stuff means interesting effects when things are very near absolute zero, because they still possess some energy.

This energy is also supposedly in the vacuum.

I think this is interesting because whereas I have not found a device of this kind that has worked properly, the theory is there and it is scientific.
