Electrostatic cooling is well documented and does not take "millions of volts"

e.g.


LASER BEAM REFLECTOR SYSTEM
United States Patent 3703813
An electrically conductive laser beam reflector is cooled by a high voltage electrostatic field created between the reflector and a probe spaced from the surface of the reflector on the same side of the reflector as the impinging laser beam. The cooling effect by the electrostatic field is of essentially the same distribution as the heating effect of the laser beam thus eliminating different and varying temperatures gradients in the reflector and the resulting distortions in the beam.

Your source even says "high voltage."  I am dealing with low voltage.

Also I never said "electrostatic cooling" requires millions of volts. I said it would require millions of volts to cool my device down by means of electrostatic cooling.

The amount of voltage depends how much mass, the desired temperature drop, and thermal  conductivity. In my case the magnets are rotating at ~ 10000 rpms, and thus the effective thermal conductive is very high. There's zero, as in 0.0000000000000 chance this is due to electrostatic cooling.

1.5KV is far from millions of volts. 1.5KV on an insulator is nothing. Even rubbing against a piece of tape can cause more voltage than that, but such low voltage is not going cool it to any measurable temperature here.

Anyhow, as stated I've performed those experiments already. The rotating magnet without the toroid *heats* up, it does not cool down. It heats up because of air friction.

Maybe under the correct conditions where the goal is to achieve good electrostatic cooling one could cool it by a few tens °F, but in my experiment it actually increased by 0.2°F. Humidity probably makes a difference as well. Maybe how much the tape has been handled by hands makes a difference from oil. Regardless, +0.2°F, -0.2°F, either way is far from the 2.5°F that occurred when the toroid was under the magnets. I still don't know for certain what caused it.

Hi plengo,

You Adam's motor sounds interesting. 3°F to 4°F is a significant temperature drop! Has anyone tried to make one self-run? And where could one find the plans to build one of these Adam motors that you built?

Thanks for the links. Lot of good info. I just came across this at rex research,

Seems close to the eOrbo design.

Earlier I did a lot of experiments with no toroid, just the spinning magnets. There are two *measurable* effects here that I can see -->

1. Heating from air friction. The magnets slowly heat up due to air friction.
2. The magnet temperature quickly changes to the ambient temperature.

Ambient temperature is almost always changing due to the outdoor temperature, the Sun, wind, appliances, etc. There's only a short moments that occur twice per day when the outside temperature (over all) does not change, and those are the peak and lowest temperature of the day. Everything in the room has different thermal conductivity, including the dremel motor. More importantly, if the dremel has been running in the past 30 or so minutes it can be a few tens °F above ambient. So, when the dremel is first turned on, it will quickly drop to ambient temperature, but eventually will begin to heat up. Constant temperature fluctuations & gradients of objects in a room of a few tenths is common. Anyone who has an IR gun or temperature probe will see that.

So those are the two measurable effects I see. No doubt there's some electrostatic cooling, but it seems that is so small it's unmeasurable in this case. If my dremel motor & magnets are at the same temperature (less than 0.1°F) as ambient temperature, then the magnet temperature does not drop, it increases. If the dremel has been used in the last 30 or so minutes, it & the magnets can be a few tenths °F above ambient, in which case the magnets will quickly drop in temperature by a few tenths °F, and then begin to slowly increase, reaching ambient, and go above ambient.

Although, the above is nothing new & unexpected. Obviously #1 above, heating from air friction, was occurred in my video, which would only increase the toroid / magnet temperature, but in the full uncut video I use the IR gun to show the ambient temperature at various spots such as the wooden desk, and the ambient temperature was 67.2°F to 67.8°F. Yet the toroid / magnet temperature dropped to 64.6°F!  IMO this seems to be due to an unknown magnetic effect. This effect has been noted in other very similar magnetic machines such as the Adams motor, and is definitely worth investigating!

My IR gun is pretty narrow as it is, 12°. You can think of it as a 1 pixel thermal camera. ;-)

The part of half of yesterday was spent on replicating my video again. This time the IR gun was pointed at the magnets, but it showed 0.°F cooling, which is too close for comfort to say it was cooling.

Just as seen in my full video, I pointed the IR gun at the various locations to get measurements of the ambient temperature. Everything was pretty much the same as the video, except the magnets did not cool 2.9°F.

The next step is to let the magnets and all rest for two weeks and try it again.

The other half of the day was spent on making my interpretation of the Steorn eOrbo replication. That should be up and spinning today.
