I nearly came up with a contraption capable of perpetual motion, once...can't remember quite how it worked...but I think that I deduced that without frictionless bearings (which haven't been invented yet), ultimate perpetual motion couldn't be acheived.

But it was so close..

Doing away with money, for instance...easily acheivable, if but for one crucial element...namely, human's inate greed.

'Tangential thinking'...you can't beat it!
