Is it possible to create a device that can generate power which in turn generate more power and on and on ...

Question

The Device I have in mind should be portable and it should be a sort of perpetual power machine.

Answer 1

No. A device like this would violate the laws of thermodynamics. The First Law of Thermodynamics states that energy is conserved. This means that energy can neither be created, nor destroyed; but rather can only be changed from one form to another.
The way a generator (or any device that "generates" energy) works is by taking potential energy that is stored by some source (gas, oil, ethanol, etc.) and converting that energy to a useful form of energy, such as kinetic energy (motion), light, heat, or sound.
The second law of thermodynamics tells us that there cannot be an engine with %100 efficiency. In everyday words, this means that the energy input into the machine (the potential energy) is always greater than the useful energy output of the machine. Some energy is always lost to outside sources.
An example of this would by the hood of a car getting hot. The heat is excess energy given off by the engine. If you could build a car with a perfect engine, it would give off no heat because all that heat energy would go toward the kinetic energy that moves the car.
Your device, however, would either require %100 efficiency, which is impossible, or would require a way to create energy, which is also impossible. Thus, assuming the laws of thermodynamics hold, we can't have a perpetual power machine.
(If we could we'd never have to worry about oil/energy prices)

Answer 2

Within any given transfer of energy, certain parts of the energy will be lost due to various sources. For example a bowling ball, polished, thrown down an endless alleyway which has been waxed, will eventually stop because there is a small amount of friction present which slowly reduces it's speed and thusly the kinetic energy acting upon. Certain transfer of energy is much more effective than others from different amounts of matter. Burning coal, the amount of energy that can be produced per kilo is dwarfed by the same amount from a Nuclear power source, which is again dwarfed by the amount of energy which could theoretically be made via Nuclear Fusion. What we could best hope for would be something that could take a source of energy and utilise it to such an extent that it could store not only a large amount of energy, but also make sure that no energy loss occurs, and that the energy produced is carefully regulated. You can also use other natural sources of energy which are plentiful, for example Solar or Wind energy.

But the concept of a machine that just keeps producing energy indefinately is beyond the realms of our reality, at least for the time being. After all, you can't change the laws of physics.

Answer 3

Give u a simple answer for u. It doesn't make any sense ti hook a generator to a motor etc. every time the energy goes from one state to the outher u will loose 30% to 40%. of the energy so u will always have less power than u started with.

Answer 4

Actually, we cannot (yet) create or destroy matter or energy. But we can transfer from one to another, like heating water to make steam to drive anything. We can change from one to the other, but so far we haven't found anyway to multiply either without spending something else in the process.
Maybe you'll find a way? Somebody worked out the inclined plane, after all, without previous models.

Answer 5

Technically speaking, most likely.

Say for instance that you have a small electric motor, 1.5 volts (1 AA battery's worth...) and a small electric generator, 1.5 volts. If you connected the shaft from both of those together and the wires alike, all you'd (metaphorically speaking) have to do is spin the shaft, and it should keep itself propelled. Not forever, because the parts would corrode, etc., but it should work along those lines.

Answer 6

If we lay a pipe out,east to west, for 24 miles,18 ft in diameter,leaving both ends open the air in the pipe will begin to flow to the west because of the rotation of the earth, and that wind will cease when the earth quits rotating.

Answer 7

Nope,
That would violate the first law of thermodynamics.

Answer 8

they already did this via the nulcear bomb....released enormous expanding energy, sourced from small initial reaction.

Answer 9

no...power is energy...energy is never created or destroyed just transferred...im sorry

Answer 10

Not in THIS universe.
