STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

I think I can clear up the Omnibus/Milehigh issue.

Milehigh, what I think Omnibus is saying is the situation where say, you have a pulse electrical force that causes the rotor to rotate.  If after the pulse, you measure the kinetic energy in the rotor, plus heat energy given off, if that is greater than the pulse electrical input, you have overunity.

Omnibus, while you are correct in this, you completely failed to understand Milehigh's point.  He is talking about a continuous motor, where once it gets going, the kinetic energy in the rotor is indeed irrelevant.  When the rotor is already spinning, it takes almost zero energy to keep it spinning.  The only friction is bearing and the minimal air resistance.  So if the motor was up for like a month, do you really care about the kinetic energy in the rotor anymore?  No, it's miniscule, a rounding error, when calculating overunity.  The calculation is going to be electrical input over the month's time versus heat energy (bearings, air resistance) given off.

Egostorm??

I have made my motor using high impedance toroid taken from a differential protection sensor, a fan and reed .
With the high resistance I had a supply voltage above 100 V.
No success, the only effect was to squeak the toroid, the resonance remanis also reducing the voltage.
I suggest to don't use the reed it interferes with the magnet for a wide area of rotation, and also generates interaction torque.
the toroid was positioned tangential.
Nex step hall sensor circuit and toroid face to face the magnet.

Enjoying the thread. Just wish some of the people posting would try to remember that this is a research forum, where people come to try and discover a way to make a cheaper source of energy.
Reading on nearly every page that steorn should have used a load to prove his motor works is really annoying.
I mean seriously? You really need to repeat the fact that the product hasn't been proven to work on every single page? And in every thread that you participate in? Isn't the fact that people are experimenting with ways to make it work enough of a statement to that end?
Another poster said that it would be nice if a muting option could be added to this forum and I agree. If you know that it can't be accomplished and believe that a theory you know prevents it from being possible then you only need to state it once in the thread. Continually repeating that something can't work or shouldn't work is not a contribution.

Repeating the fact that over unity is proven by using a viable method of measuring input vs. output is not a contribution either (unless someone posts the fact that they need ideas on how to measure input vs. output). Would be great if stefan made this one sentence a forum rule that resulted in instant banning. It would probably eliminate 10% of the posts on this forum.

Talking about things that might make it work, is a contribution, and god bless those of you that continue to do so inspite of the trolls. K4Zep your level of tolerance is impressive. A few others blew their tops long ago.
Sorry to clutter the thread further.

The english version is up now :

http://jnaudin.free.fr/steorn/indexen.htm

I tried to calculate input power using the scope shot.
A = 18 Amp (10A/div)
V = 8 V (5V/div)
Duty cycle = 25% (2ms on, 6 ms off)
P = 18*8*0.25 = 36 W
Energy spent in a sec = 36 J

As there is no load, all energy gets stored as kinetic energy of a flywheel.
KE of rotor = 0.5*m*r^2*w^2
= 0.5 *0.25 *0.075*0.075*(2*3.14*2520/60)^2
= 49 J (assuming a 250g rotor)
or 35 J (assuming a 180g rotor)

So the rotor must weigh more than 200g for OU. I did a rough calculation and the weight of magnets alone comes out to be 720g !! (which means an output of 140 J and efficiency of 300%, same as claimed by steorn)
Plz correct, if I made any mistakes.

@Omega_0,

Very good. That also answers @eatenbyagrue's point about the kinetic energy of the wheel.
