Magnetic Engine

Hat tip awakenedspecies

Magnets generally don't need to be "recharged" in the way a battery does.

This weakening is typically very slow, especially for high-quality permanent magnets like those made from rare earth elements like NdFeB (Neodymium Iron Boron).

For example it is noted that NdFeB magnets can lose less than 1% of their strength over 10 years, which would definitely be a fair trade for the amount of energy they could potentially produce.

The real question is, why aren't we investing in free energy possibilities rather than spending billions and billions on waging wars against humanity?
