#1 You can make a perpetual motion engine with magnets

Most of the hydrocarbon fuels in the world are used to run some kind of machines. A machine basically is a mechanism of converting thermal energy from fuel to mechanical energy. Imagine what happens if you get a mechanical energy from some perpetual source, like magnet, which looses its energy very slowly.

However this conspiracy theory alleges that the automobile industries and government are suppressing it since it may damage the existing industries. But some say there’s won’t be any perpetual motion machines, since they defy the laws of physics — there's no such thing as a free lunch! — Which is why no magnet motor patents have ever come good.
