Is it possible to create endless electricity?

I attempted this once with a large shop fan and an alternator from a ford truck. I was able to get the alternator to produce power, but not sufficient quantity to keep the fan running, all thou it did run for a short time. ( I used a impact to get the fan spinning in the first place) So the answer would have to be no. Unless you have a completely sealed system that generated no friction, and no heat which is a byproduct of friction.

No, that's what's called perpetual motion and is impossible (or improbable depending on how optimistic you are!). No motor is 100% efficient, or in other words, the energy you put into any existing motor does not equal the energy you get out of the motor. Most of the energy used by a motor is lost as waste heat.

I suggest you strap some buttered toast to the back of a cat and drop it out a window, thus producing perpetual motion as the cat lands on its feet, but the toast lands butter-side down.

no, the motor would produce less energy than it takes to fuel the generator. energy is lost through friction and sound.

I been thinking about that too! I don't reckon though cause there's still forces acting against the system such as friction and gravity...

no. google perpetual motion
