- As a matter of fact, there is such a natural occurence.
- (For the electrical case only)
-
- It's call the "electron-positron" pair. They are unstable and very short-
- lived. During their life, they orbit each other, but eventually annihilate
- each other.
-
- However, in search for the perpetual motion machine, could not the
- ATOM be considered as such? Since the electrons are in constant motion
- around the nucleus and does not radiate away it's energy -- or does it
- have to be on a macroscopic level to be considered a machine?
