It seems so benign. (I recall a plot device where evil/amoral aliens sold earthlings a teleportation technology -- great stuff! -- until the planet started getting shredded by seismic events triggered by this tech's scavanging from earth's rotational energy. | |

| Dec 3, 2016 at 14:48 | comment | added | John Dvorak | The tides' energy comes mostly from Earth's rotational energy. No perpetual motion - check. Free energy for a decent amount of time - check. The Earth is pretty massive and won't stop anytime soon. | |
