Finsrud's Perpetuum Mobile

[Omnibus]

Stefan, you write:

?Does he hold the pendulum magnet in his hand or
does he fix the thread holding it onto some kind of stand or
upper rod ?
Did the pendulum really never come to a stillstand when you watched this
experiment ?
How exactly was this setup ?
I think this could be much more important than hos whole machine
he has...?

No, he doesn?t hold the magnet in his hands. It is suspended on the ceiling. As I said, at the end of the first movie you can see Finsrud drilling a hole in the ceiling, preparing for the pendulum experiment.

The pendulum eventually comes to rest but it takes much longer time for it to come to rest when there are magnets, although the starting height is the same.

I don?t think the experiment with the pendulums is more important than the machine itself. There?s a lot more needed in studying just the time and trajectory of the swinging magnet than what I saw to draw serious conclusions. The conclusions from the device are straightforward and are shocking (in saying this I?m excluding fraud for which there is no evidence). Finsrud?s machine is the most shocking and conclusive experiment so far in the area of magnetic motors and of perpetuum mobile in general.

@mickestocks2006, the longest time I understand has been weeks. Exactly how many I don?t know. The device stops by itself, due to slight constructive disparities appearing in the course of its work, wear of the tracks etc., and causing it to get out of synch. This in no way, however, proves that it isn?t a perpetuum mobile.

The fourth pendulum is enclosed inside the supporting column and is somewhat thicker than the rest. At its lower end there is a set of magnets attached facing another set of magnets imbedded in clay at the bottom of the device. These bottom magnets also affect slightly the swinging of the main three pendulums. You can see this in the video in these parts where the bottoms of the pendulums are seen. The displacement of the fourth pendulum or ?pendulum? is very slight and depends on the position of the heavy steel ball (~820g) on the track. As I said these subtle additions to the construction (the fourth pendulum and the magnetic effect on the three external pendulums) ma be helpful for the running of the device since they ensure certain instability of the track. However, the main effect is due to the ingenious solution of the ?sticky spot? problem ? much like the SMOT solves it. Whenever the ball approaches the magnets it retracts so that the ball can overcome the ?sticky spot?.  Once the ball has overcome the sticky spot the gravity returns the magnets in their initial position with maximum attraction. Think about it ? how close to the SMOT this is. However, here, in Finsrud?s device, instead of the ball escaping the magnets, the magnets escape the ball. And all that is self-inflicted, much like in Torbay motor.

@Stefan, back to the magnetic-cooling system. The phenomenon you refer to cannot explain away Finsrud?s perpetuum mobile. Aside for the fact that it is not at all evident that this magnetic-cooling effect is present in Finsrud?s steel ball, even if it is present its effect would be the opposite to those necessary to drive the ball. Think about it, the magnetic-cooling effect in the experiments you gave link to is due to imparting work to the system ? you need to bring the material into a magnetic field and then remove it from there. There are many other principles which use work to produce a refrigerator effect. Your fridge doesn?t cool down spontaneously, you have to plug it to the mains.

Thus, even if there were a cooling effect in Finsrud?s device of the type you describe it would consume rather than produce work. As a matter of fact, the common materials (stainless steel and ceramic magnets) are not known to produce any tangible heat effects due to the introduction in and out of the field which sometimes is very rapid and the fields are very high. The article you cite describes special conditions and very special alloys. And, as I said, even if Finsrud had used such alloys, he would not have been able to have the ball turning for hours with no input energy observing at the same time the cooling effect you describe ? the cooling effect requires spending of energy.

you need to bring the material into a magnetic field and then remove it from there.

Exactly this is happening.
You are bringing the iron ball into the field of the permanent magnet
and then you are removing the permanent magnet again as the ball rolls on.

So there is probably the magneto-caloric effect happening.
Okay, the effect is very small, but it will be enough to convert
environmental heat on a 100 % conversion process into
mechanical energy to overcome the frictional losses
of the ball rolling on the alu rail track.

It is probably only in the range of 1/100th degrees celsius
and the ball having friction on the rail will also heat up on the rail,
so it probably compensates back and forth...

This so is a perpetuum mobile of a second kind,
as it violates the second "law" of thermodynamics,
which is by the way no law, but only an experience
which now has been proven through the Finsrud
device to be no law at all.

We can really easily explain it by violation
of the second "law", no need to violate the first law
of thermodynamics.

But surely it is a great achievement and really very
ground breaking !

2. So how long is the pendulum thread in the 12 magnets experiments ?
about as long  as the room is high ? So he hangs it to the ceiling
and it bounces back and forth over the magnets laying on the floor ?
Did he find a position, where the pendulum magnet never
stopped ? Or did it come to a rest ?
Only much later ?
How long is the time compared to each other ?
Many thanks.

@Stefan, you wrote:

Not exactly. Think about who is doing what. It?s easier to understand it in terms of a SMOT. The net energy when the steel ball travels along a closed loop is zero ? put the ball at the entrance of the ramp, let it go up the ramp, let it fall off the ramp and then bring it back to the beginning of the ramp. In doing so no net energy has been gained in the magnetic field. Magnetic field is a conservative field. Whatever energy has been gained when the ball was attracted by the magnet (heating in your terms) is lost upon the return of the ball to the initial position (equivalent cooling has taken place).

The excess energy we are so much concerned about is produced in the gravitational field ? magnetic field has lifted the ball spontaneously (in the gravitational field) to a height h and gravitational energy mgh has been imparted to the ball at the expense of no energy spent. This is the excess energy (in simplified terms) which is created out of nothing and which, if the device is properly made, makes it self-sustaining.
