[DOC] [TLE] Perpetual motion - Wikipedia [PAR] Perpetual motion is motion of bodies that continues indefinitely. This is 
impossible because of friction and other energy-dissipating processes. A 
perpetual motion machine is a hypothetical machine that can do work ... This kind

... Just reduce the friction to zero, and all we'd have is a perpetual motion 
machine... [DOC] [TLE] Is perpetual motion impossible? - Bluffton University [PAR] Perpetual motion machines are forbidden by the first two laws of thermodynamics
. ... the type which generates energy from nothing (forbidden by the First Law) 
and ... magnetic tops, minimize energy dissipation -- typically friction -- in some 
way. But none of them do it perfectly and they will all run down eventually; notice 
that... [DOC] [TLE] February | 2010 | Random (Blog) [PAR] Most perpetual motion machines are based on a simple machine, the ... going 
down on the wheel, so that the right side will always have more weight, ... Many 
other types of overbalanced wheel have been tried, such as rolling ... the entire 
thing will show that it will eventually stop due to friction, like all of the other 
machines. [DOC] [TLE] Perpetual Motion - Kilty's [PAR] If this is a perpetual motion machine you need a really low friction, precision ... 
Impossible machines. ... actually run down slowly, so they aren't truly perpetual 
motion machines. .... The first law demands that all machines have a source of 
energy, but, .... This machine will run forever, and is a machine of the zeroth kind. [DOC] [TLE] Perpetual motion - RationalWiki [PAR] Sep 19, 2016 ... An advanced form of a perpetual motion machine is a device with an output ...
