Found this very interesting clock in a section of the British Museum - London. To all the people are writing it's not a perpetual motion machine, I KNOW, IT'S NOT. 'Rolling Ball Clock' only wouldn't have attracted over 2800 to watch the video! The video has been done simply because THIS CLOCK IS COOL. From the tag in front of this masterpiece: "Rolling Ball Clock - Santiago James Moore French. Royal Exchange, London about 1820 Santiago James Moore French was one of several clockmakers to follow an original design by Sir William Congreve. The steel ball takes 30 seconds to roll from one end of the table to the other. At each end a catch is released, enabling the spring driven movement to tip the table the other way and start the ball rolling back. The ball travels about 4000 Km a year." Updated on 10th April 2008: Got this email from Mr Oliver at the British Museum: Unfortunately this clock cannot be called a perpetual motion machine. It has a source of energy, a coiled steel spring. The spring is encased in a brass barrel and is part of the movement of the clock, which is located above the rolling ball. Every time the ball hits the lever at the end of the track, the spring powers the movement to raise that end of the platter, thus lifting the ball and causing it to roll back again. I wind the clock every week (which means I put my energy from my breakfast into the spring!), so you can see that this is not perpetual motion. You are correct about friction - if there was no ...

Yahoo Answers For Perpetual Motion Clock

Question Is perpetual motion possible with magnets?
Ok, I know the answer is "No," but I want to understand why. It seems that you could spin a metal-studded wheel with magnets that pull clock-wise, but are somehow shielded against counter-clock-wise pull. The shield might have to move as part of the mechanism, but why should that have to use up all the energy? Once machine is working, would the magnets' force diminish as they get "used up"?

Best Answer In a perpetual motion machine, you'll have moving parts. A moving magnet introduces an electric field. A system in which the magnets follow a repeating pattern introduces a cycle, magnetism, electric field, back to magnetism, and so on. This oscillation will create an electromagnetic oscillation, which will materialize photons. Each photon will leave with a certain amount of energy, draining the energy out of your machine. That's if it operates in a perfect vacuum. If there are any molecules in the way, you'll have resistive/frictional losses, too.

Question if i was to take an old grandfather clock and rig up a solar charger?
and put an electric motor so it would wind itself so that i would never have to wind the clock again could this be a perpetual motion type machine ?

Best Answer Let's keep it simple. No it is not perepetual. Sooner or later one of several things will happen. The clock will have a mechanical break down probably due to bearing failure. The solar panel will fail since they have a finite life The charge or battery system fill fail for the same reason. Finally, the sun is going to go out at some time in the future.

Question Would this be a good idea for perpetual motion?
I got this idea while studying about water clocks -- http://en.wikipedia.org/wiki/Bernard_Gitton --. Basically I want to run a siphon system over a water-wheel: Take an open water tank (Tank A) filled with a reasonable amount of water, then raise an air-tight tank (Tank B) over the other. Tank B should have a spout of some kind to let water flow out, as well as a hose leading into Tank A to allow water to flow in. If the spout on Tank B let water fall into Tank A, then the motion of water would continue forever, right? So if you were to place a water-wheel under the spout, you could use it to power other things. ... If that wouldn't be classified as perpetual motion due to evaporating water, could you substitute something oily instead?

Best Answer No, this would not be an example of perpetual motion due to the counter-effects of gravity. If Tank A is lower than Tank B, it will take more energy to raise the water back into Tank B than you would gain from the motion of the water wheel. Thus, your system is losing energy during the process. You could get it to run for a long time with a large enough tank, but eventual entropy wins and the system will stop. Even if you wanted to dedicate 100% of the energy generated by the water wheel to a pump to push the water back up into Tank B, the amount of energy generated in the water wheel is less than the energy necessary to move the equal volume of liquid back into the elevated tank. Energy would be lost by the friction of the water particles as they fell through the air, the loss of energy to heat as the water droplets impacted the blades of the water wheel, the loss of energy to heat and friction as the water wheel spins on its axel, etc. Unfortunately, a practical perpetual motion machine just isn't possible in an environment where friction and gravity exert an influence. Hope that makes sense!
