Prepetual motion has long been a reality come true. something I have been intrested in for years. The factor is "Overcoming Friction". If rotation is involved or some type of wheel there has to be a axel and a shaft, Rotation on the axel causes friction which in time will slow the wheel and eventually stop.
Flux capacitors. Preferably big ones.
Perpetual motion machines do not exist. If they did we would not be paying almost $3.00/gallon for gasoline, as a perpetual motion machine implies free energy. Newton's laws tell us that is not possible. For further explanation read up on Newton's laws of motion and thermodynamics
Lots of people who don't understand thermodynamics very well. (Perpetual motion machines are not possible.)
Neither first or second kind of perpetual motion machines can be constructed, beacuse their existence violates the first law of Thermodynamics
Perpetual motion machines are theoretical only. No one has actually invented one. A perpetual motion machine would have to be able to provide its own source of energy to continue operating.
No one, and no one ever will, since perpetual motion machines are a scientific impossibility.
Perpetual motion machines have, to date, always been a disappointment.
No, perpetual motion is prohibited by the laws of thermodynamics.There are machines that might at first seem to be perpetual motion machines but only because their source of energy may not be readily apparent.add. But in economics, inflation serves the purpose of a perpetual motion machine, in which more currency is created continuously. And which serves to illustrate the reality of economics.
Perpetual motion machines are an impossibility. Energy conversion is never 100% efficient. Even if it were, friction is never zero.
Perpetual motion. This answer is more related to the question "What do all machines DO NOT HAVE.
Perpetual motion machines do not exist. There is no machine that will keep on moving by itself without any added power. Windmills are driven by the wind. When the wind stops blowing, the windmill stops turning.
No. As Homer Simpson once said " In this house, we obey the laws of thermodynamics"
This would be called a "perpetual motion machine", but they don't exist.
