He is pulling your leg :)
Unless St thinks that the world is flat (and if it is, where are you
then?) then he is seeing how long it would take for you to cotton on.

Opps! Scratch the last post to Gail. :)
Sorry!

Think of it this way. If you have 2 pans of water, same volume, one's just
above freezing point (0C) and one at boiling point (100C). Can you use the
pan of boiling water to bring the second pan up to boiling point?
Similar thing, just with heat, instead of springs

Heat's just the loss of energy from the system. Even if you have a
frictionless material, you cannot create energy. Say we have found a
frictionless material (or one with such low friction it's barely noticable)
Say a fully wound spring as an amount of energy in it (X joules). You use
that to increase the speed of a vehicle, (using Y joules where X<Y), then
all you have left to rewind the second spring is the left over (X-Y)
Energy can never be created or destroyed. It can only be converted from one
form to another - 1st law of thermodynamics

Oh! That's a good anology Gail! No, of course that couldn't happen, and I
can see no way around it to make it happen other than making use of other
materials to do it. For example, (and this is off the top of my head): Steam
from said hot water soaks a towel above it. Towel gets heavy and falls onto
lever, switching gas on under cold water pan to heat it up
But there are those other outside influences again. I see the problem now.

Maxwell's demon could :)

Doesn't that mean the universe will suffer when Entropy increases?
Thus proving the end of society as St first pointed out.
You've just proved his point. And if he was right about that then
maybe the Perpetual Motion Machine is possible after all!

Btw, literally just found this - the author is either psychic, or he knows
what he's taliking about. Note the date. It's a good read.
