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

I think Steorn is making it look like that orientation can vary. Because indeed it would seem like the demo floor units have "standing" toroids:

while the video demo unit has "laying" toroids:

One may or may not have an advantage over the other.

Hi Broli,

I have seen photos both ways as you show.  I think from a torque and canceling effect the best way is how JLN did it, FACE on the toroid.  My motor while demonstrating the effect is horrifically inefficient and about ready for the parts box.  I will be building a much more robust motor over the next 2 or three weeks because IF it is a ou device it must be able to run for months on end.  I want to build a HI rpm motor and drive a low rpm generator reducing the motor by a factor of 4-6 to further amplify torque.  I am truly happy to see other people building and thinking.  Great things will come from this!!

I'll be discussing my Steorn experiments & stuff in the tech thread -->

Hi Ben,

How did you put the magnets? All North, all South or alternating?

Stephan:

Well,you only need to use a higher voltage for the power supply,
then you reach the current level for saturation already at 1/5t of tau Ontime.

Maybe you need to use then 200 Volts as the supply voltage.

Then you would only need maybe 1 Watts of input power,
would get 0.9 Watts out via the BackEMF recycling circuit and
would get 3 Watts mechanical power output due to the rotation of the rotor
driving a mechanical load.

This all sounds nice but I don't see that working out in real life.  For example, if you are implying that you only reach saturation at the end of the 1/5 tau, then your "saturation duty cycle" is very low and the motor may or may not work.  Also, the amount of time the core is saturated may not be long enough based on the speed of the rotor.  That would imply that you need a setup where by 1/5 tau the core will have been fully saturated for 4/5 of the 1/5 tau time.  That means that you have to supply an excess of current and "over-saturate" just so you can keep the core mostly saturated.  In addition, you may have to do several 1/5 tau cycles, one after the other, just to keep the core mostly saturated for a long enough time for the magnet fly-by.

You can mix and match the excitation voltage, maximum current at the end of 1/5 tau, the number of windings around the toroid core, and the number of times you have to do the 1/5 tau pulses to keep the core mostly saturated for a long enough time.  I don't smell any victory at the end of this process.  You can compare how much energy you expended to keep the core partially saturated to how much energy you recovered from the BEMF collection capacitor and we know that the energy that you expended will be greater than the energy collected in the capacitor.

When you compare the above with just a normal energizing of the toroidal coil like we see in K4zep and Steorn's clips, it would not surprise me if the total net energy expended for the "complex" setup described above as compared to the simple straightforward setup would be the same.  There is a good chance that the total net energy expended for the complex setup would be even more than the energy expended for the simple setup.  Also, don't forget that the simple setup keeps the core 100% saturated for almost all of the time, while the complex setup would look like some variation of a sawtooth waveform for the current, where the core is not 100% saturated for almost all of the time.

I smell a no-win situation here and I have seen similar cases where people try all sorts of complex solutions to their problems and in the end the simple straightforward solution is the best solution.

Here's the video footage of the temperature dropping. It goes far below ambient temperature. Please read the youtube video description for further details,

Paul,

Do you have a current flowing in you coil?  It appears that you have demonstrated a new way to get Magnetic cooling in a common substance.  I suspect that RPM would effect the cooling.  A basic schematic of what you are doing would also be helpful!!!  Might have to start a new thread on the really excellent discovery!!!!!  See, great things, Ideas are coming out of the wall and growing right before our eyes!!!
