There are 3 types of perpetual motion machines, depending on which of the 3 Laws of Thermodynamics you break. And you can't break the Laws of Thermodynamics.
Simply put they state;
Law 1 - Nothing is free in this game
Law 2 - You cannot break even in this game
Law 3 - You cannot get out of the game
Source(s):
Einstein said that of all the Laws in the universe, the Laws of Thermodynamics will be the last ones broken. In other words, we'll be able to defy the Law of Gravity and fly before we invent a perpetual motion machine.

No. Perpetual motion does not and will never exist. It violates the laws of thermodynamics.
People have made machines that run for a VERY long time, and produce a small amount of current, but eventually, due to friction, the parts of the machine will wear down, and therefore, the motion is not perpetual (perpetual meaning that it could therotecially run until the end of time).

The simple answer is no. Perpetual motion is only theoretical. As long as there is gravity, and therefor friction between the parts of the machine, then there will be a loss of energy. Theories state that perpetual motion pay be possible if produced in a no-gravity situation, but then the energy would most likely be lost in the transfer from the source to the place it's being used.
No dice buddy, it just can't happen.

Neither potential nor kinetic energy can be created or destroyed - this is a basic premise of physics.
A perpetual motion machine would necessarily have to be creating energy - the only way any mass could do that would be to consume itself in a nuclear reaction by converting its mass to energy.
In spite of this, I'm sure there are many otherwise intelligent people out there still trying.
However, I learned a long time ago to never say never.

One of Newton's laws of motion is that a body in motion will remain in motion unless acted upon by an outside force. But a mechanical device is subject to outside forces (air resistance, gravity, friction, etc.) so while a device that mimimizes those might run for considerable time those forces will eventually bring it to a stop. Even more so if energy is removed from the device (by having it do some work). Even in a weightless vacuum there's still friction to contend with.

Many have deluded themselves into thinking they have, but no.
There is ALWAYS friction and other forces acting on any device, and ALWAYS energy escaping, through heat radiation if nothing else. The only way to avoid heat is to avoid all motion down to the molecular level, so there will always be a drain of energy if you have any moving parts.

Yes. We figured out it defies the laws of the universe. Where were you? This was hundreds of years ago.

well... like it was said before, it's possible, in theory.
For instance, if you can throw an object in a total void, at 0K, then it would go on for ever...
But for any system in th real world, it's not possible.
Look up the laws of thermodynamics.
