Perpetual motion machines (hypothetical )

May 26, 2012 - These are jokes

May 26, 2012 - The second law of thermodynamics is clear, but there's a force applied constantly to every machine that let them move: gravity. No true perpetual motion, just something that looks like perpetual motion.

May 26, 2012 - if these were truly perpetual wudnt you just leave them running the entire time to demonstrate their perpetuality? :/

May 26, 2012 - the wheels are running to smooth to not be connected to an engine....

McAsymptote Says:

May 26, 2012 - It would be impossible to watch an infinite video.

StarStuff82 Says:

May 26, 2012 - theoretically, in a frictionless environment they would contine forever, but as a closed system, nothing in and certainly nothing out. if you paid attention, then you would see that they dont just start moving on their own so the laws of motion and thermodynamics are still intact. they are able to maintain the initial energy input. so to answer your simple question...as long as it takes friction to dissipate the initial energy input.

May 26, 2012 - Can someone explain to me why the first one wouldn't work? I understand that perpetual motion is physically impossible, but it seems like there would be no way for the water to stop flowing.

DaAlexboiii Says:

May 26, 2012 - @McAsymptote not quite was i was gettin at :9 i meant if they go on forever why wud he need to start them? wouldnt it be easier to just leave them there?

The liquid in the tube would never rise above the liquid in the cup. simple.cone moving uphill:the tracks are slanted, so it moves downwards according to the curve of the cone. simple.cylinder on two rollers:lol... the rollers just hold them there via leverage against the cylinder, the cylinder isn't overbalanced. Balls in compartments&Hs in cresents&classic overbalanced wheel:There's more weights on the other side so it counters the torque

May 26, 2012 - I think the first one is the only one that could be modified with clever thinking so that it would generate some harvestable energy. Using something that lets in the ocassional air bubble to push extra water up periodically. That would not violate laws since we'd be using air's natural tendency to go up. Combine that with one of those water things they use on farms to use gravity to twist a gear and dump it down into the bottom. That could make enough electricity to make a bubble + a little more

latinocheech Says:

May 26, 2012 - I'm gonna build one and see what I can do with small time parts. The other thing I could do is make the cone pressurize the water a bit more by messing with angles to see if it has an effect or not. In an outdoor scenario water could simply be replaced by rain as it evaporates if it rained enough. There has to be a way just as we use levers and gears for leverage, to leverage natural laws and properties of meterials to partially aquire their energy during processes.

JesExaVid Says:

May 26, 2012 - and where does the heat come from ?

JesExaVid Says:

May 27, 2012 - gravity ?The force created by a falling object is equal than the force it took to lift it in the air in the first place.

May 27, 2012 - Next time you fill a beer bong watch the beer in the hose.... It's called hydrostatic pressure. You'll never have the self filling flask scenario. That's an illusion. If it worked people would have them in their house on a large scale with a water wheel on magnetic frictionless bearings making their own power. People should quit wasting their time trying to build something that defies these laws because their brilliance could be put to better use on present technology.

latinocheech Says:

May 27, 2012 - I agree that alone won't work, but in combination other things you could change energy exchanges to keep things going. In programming at a glance some things seem impossible, but eventually you learn to make complex things from lots of basic things. This can't be that hard. The unlimited energy is constant gravity, there must be a way to exploit it.

latinocheech Says:

May 27, 2012 - Think of an atom bomb. Never would anyone think an atom could expel that much energy. So there must be lesser reactions as well.

toamaori Says:

May 27, 2012 - what they are trying to say in their replies is... "I don't know" I would be interested to see how long they run before stopping.

Domagoj176 Says:

May 27, 2012 - ok the first one can be used like elektrical powerplant, but it needs to be in bigger much bigger scale, and thats good idea for cooling systems like cpu wattercolled system

jconsarnaus Says:

May 27, 2012 - 2nd law of thermodynamics prohibits perpetual generation of work not motion. for example if the self flowing flask had no friction and was sealed it could very possibly be perpetual or as close to perpetual as you can get.

Assassin8erated Says:

May 27, 2012 - how about if you had a whole heap of these "perpetual" (i know what perpetual means, just that these machines are most likely not perpetual) machines powered a small generator, the this is connected to a motor which can kick start one of the machines if it stops.
