Cooling effects in Steorn eOrbo

[PaulLowrance]

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.

For the record, I am able to log 1.5 kilovolts as read on my ElectroStatics Model 9000 electrostatic meter held one inch from a piece of plastic tape rotating on my dremel tool. The meter reads that the charge is positive(+).

With the tape removed and a sanding disc the same diameter, there is nothing registered on the meter.

I have repeated this several times. The positive charge is being accumulated on the plastic due to air friction. It dies away when I shut the dremel off.

This is consistent with my guess that electrons are ripped off the toroid insulation causing a very low level surface cooling effect as picked up by the IR Temp meter.

I will do some tests with temperature probes to see if the cooling effect can be induced.

Please excuse my interruption, I'm probably way off base, just reporting what I see.

Kind Regards.....V

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.

[Vortex1]

Agreed, however in my tests with a dual thermometer the electrostatic cooling effect is rapid, however air friction seems to shortly override it causing the frictional heat to prevail with a resulting temperature rise after the initial drop.

I made no claims for the temperature of rotating magnets or stationary toroids. No toroids or magnets in my test....yet.

Just trying to demonstrate an initial temperature drop of a stationary object near a source of rotating positive (+) electrostatic field.

Anyone wishing to get a good idea of what can be done with electrostatic cooling should read the attached patent. Extrapolate the numbers downward and form your own conclusions.

Kind regards.....v

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.
