Perpetual motion could be used to provide electrical energy. Should an electromagnetic generator be constructed around
Darwin's grave in the year 2006, it would be able to power approximately 25% of the world's electrical consumption by 2008. The machine would work in the following way: Darwin continually spins in his grave due to the presence of mindless idiots in the human race, of which there are a great number (thus increasing Darwin's rotational speed). All you need to do is electrically charge his body and you have an
infinite power supply (just as human stupidity is infinite). There have been, and always will be, idiots in the world, as provided by teenaged mothers, thus providing
perpetual motion on the part of Darwin's corpse.
