Some inventions are good inventions, others are bad inventions.
We all know what the good inventions are, the bad ones are guns, atomic bombs, poison gases, germ warfare, etc. A good invention is intrinsically good, waxed paper, buttons, phonograph records, tape cassettes, and so on. A free energy machine falls into this category, it produces energy without consuming it, creates no pollution, and liberates Mankind from centralised control of his freedom. It could eventually liberate him from money. There are other free energy machines, but these are only lesser manifestations of the same principle, the extraction of electrical energy directly from space.
