Energy may be created when the "muscle" contracts, but if I read correctly, energy is needed to get the "muscle" to expand.
Supposing that the Law of Energy Conservation, or whichever other law applies, is respected, how can you get more energy out of contraction than you put in to expand ?
Or is this the definitive rebuttal to the everlasting pendulum affair ? Maybe proof of the infamous zero-point energy theory ?
