perpetum: for ever
mobile: moves:
according the latin ethimology of the concept a drinking bird will move forever if placed for example in a well
according physics a perpetuum mobil of the second kind is that one that not only moves as the perpetuum mobile of the first kind( as the solar system orbiting) but that if there was no friction would move faster and faster and with friction will keep moving
so in this century with been witness of the discovery of the holy grail of science a perpetum movile
but the universities sponsored by petrochenmicals have gone fast to brainwashed us into that yes it moves forever but is not a perpetum movil cause is not magic just evaporation
what about 1 km big 1000 tons drinking birds to solve energy problems?
