Yahoo Answers For Perpetual Motion Water Wheel
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!

Question Why are perpetual motion machines impossible?
How can it be impossible? I have an idea that involves a water wheel and it keeps going in a circle. If I had the right equipment, I would build it but I don't so I would like to know HOW it is impossible. How is it impossible to make a machine machine NEVER stops going? I mean, If you use water and do it right, then the machine won't stop, so HOW?
Best Answer If you are thinking about hydro-electric power or the "drinking bird"...both of these may appear to be the perpetual motion machine. However, both of them depend on nature's power cycle to operate, which involves evaporation of water caused by the sun, condensation of water vapor into droplets, and rain. The drinking bird will continue its repeated motion as the water dries off its head. Once fully dry, the bird will take a dunk in the dish and absorb water. When the dish is fully empty, or the background begins to fog (which ever comes first), this will no longer be a perpetual motion machine.

Question Can "free energy" (perpetual motion) be achieved through buoyancy?
The easy answer is "no, because of the law of conservation of energy", but I would still like to scientifically discuss the following idea: Imagine an underwater "ferris wheel" inside a large water tank such that there are upside-down cups on the outside perimeter of the wheel. At the bottom of the water tank, there is a small hole through which air is pumped, so that it fills the cups with air as they pass over it. This results in circular motion of the wheel as the cups are filled as they pass over the hole, and emptied as they reach the water's surface. What I am wondering is how much energy would be required to get air bubbles through a hole in the bottom of the aquarium into the cups, and how much energy could be produced by the rotation of the wheel. I would be interested in seeing actual calculations. I do not have the background in physics necessary to answer those questions, but it seems to me that it would take very little energy to pump the air through. The wheel is connected to some kind of electrical generator, which is used to power the air pump. The real question is whether enough power can be extracted from the wheel's rotation to power the air pump.
Best Answer First of all, this is not free energy. You have to pump air into it. The energy required to pump the air depends, among other things, on the resistance to the air motion. You also have to consider the resistance to the cups when they are moving down. Now if all the cups have air, then you reach a point where the clockwise moments = counter clockwise moments. With the resistance, the ferris wheel will eventually reach a state of zero motion. Even if there is no resistance (purely theoretical), then the wheel will attain some constant angular velocity, and will thus have a certain amount of kinetic energy. That's still fine, UNTIL YOU START EXTRACTING ENERGY FROM THE SYSTEM. If you want to put that energy to some useful purpose, then eventually you'll extract all the kinetic energy it possesses. So it will give you some energy for a short period of time, and you will find that this energy is equal to or less than the energy you put into it via the air. RE: the additional details you posted. Look at it this way. If you input 5 J of energy into a system (via the generator). At best the system will give you 5 J of output. In reality it will be less. So if you take all of this 5 J and re input it to the generator, then you have nothing left to output. And in reality there are losses during energy conversion. These problems work best when the rotation is caused by some natural means e.g. flowing water from a river or waterfall, or wind etc. That way you don't have to provide the input. Nature does that for you. You might be interested in the article below.
