In the Superconductivity chapter there is the following quote
The part that I question is the to part highlighted in bold. Is this not exactly what scientists today are trying to do with Fusion Reactors? They are trying to get more energy out than what they put in. To my knowledge they have not yet been able to break-even but when they do (and I believe they will) would this not constitute as an "over-unity device" ?If you're thinking this appears to be a form of perpetual motion, you're correct! Contrary to popular belief, there is no law of physics prohibiting perpetual motion; rather, the prohibition stands against any machine or system generating more energy than it consumes (what would be referred to as an over-unity device).
