In the Klostermann video, there is a pretty strong reaction that drives the projectile while using air. Since Russ has shown that air does not work as well as Hydrogen or He, the question is why is Russ's reaction less potent than the one in the video? What is Klostermann doing better? I think that is the tract that needs to be investigated to see if it is just air expansion or something liberation of extra energy. He does state that he used 600 joules and 500 V. That is a large amount of power to be pulsed rapidly for an engine, which he doesn't do here. Getting a powerful reaction using a low joule input is the real issue.
Its difficult to tell here but he might be getting magnetic repulsion. Normally, I would say this should not happen in a solid aluminum piston because it would short a circular current but if the pulse was fast, a current might circle around the outside edge of the piston due to skin effect. In HF transformer design, litz or multi filar magnet wire is used because of this.
I think his high energy input gives induction in the aluminum and that drives his piston out of the cylinder.
I'm not impressed by Klosterman, it seems he can not make an engine and begs for the linear free piston thing of others. If he really knew the papp secret, he would use less input energy.
Accounting for the Papp vacuum
Contrary to the beliefs of many, I consider it probable that the force that moves the piston in the Papp cylinder is produced by electromagnetic forces and not by an increase in pressure in the gas within the cylinder.
If this opinion is true, this electromagnetic force not only produces energy when it moves the piston upward, it also produces energy by creating a vacuum in the cylinder as the piston moves upward.
If this vacuum production is happening, then how do we add in this energy in the production of the vacuum when we determine total energy output applied to the upward movement of the piston?
It seems to me that the easiest thing to do in this situation is to remove vacuum production from the energy measurement.
By placing an inflated flexible gas reservoir on the spark side of the spark discharge cylinder volume, no vacuum will be produced.
As the piston rises, gas will flow into the cylinder from the reservoir and no vacuum will form.
A gas filled balloon connected to the cylinder volume where spark discharge takes place will do this vacuum removal function nicely.
Bob Rohner may be underestimating the energy produced in his popper because he does not account for the production of suction from a vacuum generated inside his cylinder.
The energy of this vacuum is only recovered on the backstroke of the reciprocation cycle.
A weight based kinetic energy assessment on the upward movement of the piston does not account for the production of this vacuum energy.
But when he is making an engine, he uses the vacuumforce if he wants it or not.
Your thoughts that the force is of an electromagnetic nature, should be testable in some way. Maybe by using a plastic piston? Also it seems that when the pressure meter is left on at poppingtests, it blows the thing up. Bob says somewhere that it costs him already some meters.
Maybe your favor for a magnetic impuls reaction should be tested in a separate simple setup. Also concider the possibillity that both forces are acting at the same time..?
If you put the gasreservoir there, then during the reaction the gas of the reservoir should be sucked into the chamber.
Then again i think it strange that a pressuregadge blows up when left open to the proces, or can it blow up by vacuumforce also?
