Errr..obviously the fine details have to be worked out, but
with some kind of Fresnel-ish device (or possibly just a
triangular prism) it should be possible to make perpetual
motion device.
The basic concept is that in Brownian Motion all the
particles move in a random direction and so all
the force is
counter balanced.
So, what is needed is some way to make the particles
going the wrong direction (from our point of view) go more
in the right-ish direction. One tricky version would be a
scanning laser, which would give a glancing blow sufficient
to alter its course, and subsequent blow to get it going in
the correct direction.
I'm thinking something like a fresnel lens,or the laser, or
maybe even a big lightbulb?
To speed up the "does this thing actually work?" period I
suggest large particles, (like smoke) and zapping the whole
lot with microwaves to bump up the energy in each
particle.
Gosh, that was tiring. I await the ritual humiliation of
when someone points out the childish flaw in my logic.
Anyway, back to writing that steampunk Sherlock Holmes
wossername story.
That's nineteen zero's, and I'm assuming "useful lifetime" is meant, so I didn't make it 40 to 10^10^76 depending on whether you believe in proton decay

You are inputting energy into the molecules, via the lens.
That sort of thing is not allowed, when trying to build a
perpetual motion machine. |

Err..I'm just doing that to speed up the test, as I'm
not a patient person. |

This is not even not even wrong. |

We need somebody to monitor the expansion of the
universe, to make sure it doesn't stop. This will be a long
term project. Who can we assign? |
|
| |
I'm going to be around for at least 24 hours, or within a bare
maximum of .00000000000000000001% of the lifetime of
the
universe's time as compared to anyone else alive today.
How much does the job pay? |

Shirley a more pressing need is to move any furniture
and ornaments before the expanding universe knocks
them over? |
|
| |
This (the idea) is what Maxwell's Demon does during his tea break, isn't it? |
|

Far too quantum-ish. Why not just go all the way to
popping out of existence here and popping into existence
there, but, randomly and all at once in every location
and in every reality and when you realize you have
conveniently popped-in at your destination, you simply
turn the thingy off and stay a while? |
|
| |
Ta...popping off to go get a pint, now. Lovely idea,
though. Can't imagine all the fantasy places I should like
to visit,though. Perhaps into other times and joys. |

OH, yes. One should be advised never to use the device
while inebriated or in need of finding a loo. |

//Not really, everything else expands as well. |
