Perpetual Motion Machine
I recently saw an article on perpetual motion machines. I spoke to a work colleague about them, and although he is a futuristic type of guy who can make robotic things and is a wizz on 3D printers, he said it was not possible.
The one I saw was based on ball bearings to give the energy for constant rotation.
So are perpetual motion machines a myth or have one of you made one?

Total myth. Even the universe will eventually end up room temperature.

I heard you could make a perpetual machine by strapping a piece of toast, with the butter side up, to the back of a cat.

The problem with perpetual motion is that every body in motion interacts with its environment causing loss of energy.

Perpetual motion is not possible as it would break at least one of the laws of thermodynamics. There are plenty of articles online explaining this in detail, google will find them for you.

If there was no friction between any moving parts of given perpetual motion machine once it was moving it should keep going, but friction is here to stay so nope, there are various means of reducing friction to very low values but it is still there.

I like this topic, its fun to think about. The current understanding of how this universe works does not allow for a "perpetual motion" device as such.....

Elanjacobs that's the definition of room temperature
But thanks for being so literalSteve

I think I might be married to one, a perpetual motion machine I mean.

I haven't finalised the details yet, but imagine a vacuum jar like they had in science labs at school, with two magnets sort of levitating, and a spinning disc. No friction from air, no friction from items touching each other, just a minor problem in working out how to get the disc to spin. Maybe the disc would be one of the magnets?
Oh, and it doesn't matter what the room temperature is!
How much grey matter will be used up thinking about this contraption? Should keep someone awake for a while!
