Fresnel-ish lens-ish and Brownian Motion perpetual motion thingy

  [vote for,

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 https://en.wikipedi..._expanding_universe

       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?

       //monitor the expansion of the universe//   

       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.   

       Ahem, see link above.   

       Need I mention "Planet Jupiter: Packed by weight, not volume. Contents may settle in transit".
