Perpetual motion machine ?

Here is a video of a very beautiful Perpetual motion machine built by norwegian artist Reidar Finsrud .
This machine ran for three days with only a tiny fraction of a second loss of speed .

The definition of "perpetual" must have changed since I last looked at it.

Nice machine, but I think a lot of people can invent machines that run down slowly.

Yes I have seen it before, fascinating machine.

Give it a short while and the detractors will be here to tell you it is all impossible.

Won't be long, they seem to hate the thought of perpetual motion.

ETA Crap, one of them beat me to it.

A quick google search shows the inventor himself says its impossible.

Over at overunity.org there's a bunch of experimenters searching for ways to make true perpetual or even overunity machines.

And I quote from a posting there...

I recently visited Finsrud at his art gallery in Norway, and talked for many hours about his machine. Finsrud told me very clearly in Norwegian (I also happen to speak Norwegian):

"the machine will not run more than 14 days, and right now without tuning it will not run more than 2 days. The machine is not made for perpetual motion, but is simple an experiment in Physics."

I am not sure why people are twisting the facts and making this into a perpetual motion, or over-unity machine - when the inventor himself says it is not.

I saw the machine running with my own eyes, and the speed of the ball slows down - just as Mr. Finsrud pointed out, while I was there.

Noted , and added a `?` to the thread title.

And another posting...

I just recently read in the NET-Journal an older article, where Albert Hauser interviewed Mr Finsrud.

It is a very open interview, where Finsrud explains how the machine does work, also with a labeled drawing of the mechanics.

Also there he indicated that the machine will run for about 14 days, at most 3 weeks.

He also states, why he did this machine, and why he called it "Perpetuum Mobile". He did this, to get some free public media attention...

While its certainly not perpetual, it is very efficient and beautiful to watch.

I think he could improve it by sucking the air out of the glass case to produce a vacuum, thereby eliminating air resistance. It looks like has done very well reducing surface resistance of moving parts and heat losses.

Theoretically he could converge on 100% but realistically never hit it, so it may be possible to get 99.999% efficiency and have it run for lifetimes - by our observation that may seem 'perpetual'.

>100% efficiency is a pipe-dream, the energy has gotta be coming from somewhere. Over-unity observations usually involve a badly chosen system boundary or incorrect calculations. Who knows, maybe one day a newly discovered energy will produce the appearance of overunity in devices, but only because we haven't factored that energy into the balance equations.
