Finsrud's Perpetuum Mobile

[Airstriker]

IMHO, it's just an efficient dynamic sculpture. If it was a perpetual machine, it wouldn't stop. He keeps it in the vault, so why would he ever stop it ? Every time he opens the vault, he is not sure, whether it's still working or not. He alse has never stated that it's perpetual. Anyway, it's really a nice scuplture.

I have been thinking that the skulpture is slightly affected by the earth rotation. All four pendulums (including the one inside) directions will change for each cycle, and probably be powered by the rotation of the earth. The explanation I've heard is that the track is slightly twisted along with the ball so the ball allways are rolling "downwards". The delay of this twist which allow the slight offset, might be happening due to the earth rotation and its interference with the pendulums.
If this machine was placed in Australia, it would not work - Finsrud have had to design a "mirrored" version of the machine (?).

Well, this is just my guess.

Maybe a mini-replica of this sculpture, placed on a turntable, would proove the concept...?

I visited Finsruds gallery today. The Perpetuum Mobile machine was not running when I was there. As he said to me, when this machine had ran for 10 years from 1996 to 2006, he became allmost mad about the machine, because he was more and more obsessed by the machine, allways had to go check if it worked or not. So now he have made a small city with trains, people, cars, sounds, mirrors, real fishes in a small pond :-)
Anyways, if no one yet has been told the REAL reason why there is a click noise coming from this machine, the reason is a notch in the inner bicycle rim he have used as track. Now, Finsrud have placed a model, train railtrack on it. The track is made of brass - a non magnetic conductive material. The replacement to new tracks is done due to severe wear out of the original track.
Attached is a picture of the notch I'm talking about.

Later I will post a detailed picture of the while machine, and explain in detail how it works, and why it works (Told to me by Finsrud himself). I have to arrange all the photos into one big photo first. That wil take some time.

Hi All,
I visited with my girlfriend Mr. Finsrud on Monday the 18th of July 2011.

He was very friendly and showed us the perpetual motion machine and also his workshop,
where he tried  many years ago some more gravity wheel designs and also a special
heat to mechanical energy converter sterling machine.

He could not get any other gravity wheel to work, but then he concentrated
on the stopping condition of a magnet pendulum which hangs from the ceiling ( in a 5 Meter height room) and
is deflected from magnets laying on the ground in a chaotic manner.

One pendulum always stopped after a while, but then he used THREE pendulums and coupled them
via springs and then after some tweaking he got a condition, where these 3 pendulums never stop.

Each one of the  pendulums always pulls the other out of the stopping positions.
And this was the secret key to his invention.

In normal physics theory, if you couple 2 pendulums with a spring and let them swing,
each pendulum will transfer its kinetic energy onto the other and then back and force,
so the kinetic energy will be going back and forth from one pendulum to the other
and then back again, until friction will eat up all the motion.

So in coupling 3 pendulums with springs and using the magnetic forces of the chaotic movements
of the magnetic pendulums versus the magnets below the pendulum, he could achive
a constant motion, that never came to a stop.

So he made this into his machine and created from it this perpetual motion machine.

I am just uploading all the videos I took at his place.

As Vidar already wrote, after a few years he got mad about it, checking every day, if it will still work.

Also as the 3 pendulums are just sitting on inverted "V" sharp rail points , these sharp points wear out after some time,
cause the metal there builds crusts and has to be cleaned and also the dust goes onto the
rail and the ball and thus it gets dirty and it will stop after a few days or weeks.

So he normally lets it sit there not working and only will clean and start it , when
some tourist groups will come and want to see it.

Is he working on a bigger machine ?

No, he is mainly an artist and his quest for perpetual motion was done
with this machine.

He said, everybody can build and replicate this machine, if he wants for himself ( but not sell it).

He is currently working on a different art project regarding a model city with special 3D miirror effects
and a very nice model car and train transportation system looking very realistic, but this has nothing to do with
his perpetual motion machine.

He is is also a very talented sculptor and has invented his own sculptor "stone sand" from which he builds
his sculptor figures.

His special material is made out of chromedioxid,silizium and graphite and a binder or something like this
and is very hard.
He said, when in 10.000 years all of our culture will be gone and some archologists will digg up
the grounds at his place, all other things will be vanished, but what they will find are his sculptor figures.
They will last very long time...


So enjoy the videos.

Regards, Stefan.
