I think parrfin wax would be better and the wax melting is good for the operation as it behaves like oil, having self healing properties, but when stored, is solid and will not spill if moved or knocked over, and does not make the awful messes that oil does, and when melted can be vacume presivated to getinto the smallest of cracks, i have also seen a lot of wax on old electronics as a poting agent as well..............

On mots i have never found one that wastes less than 120 watts while idle, and i had 40 or more at one time when I was getting microwaves by the pickup truck load, from an applaince shop, was using them to build welders, and wante4d only to use the xformers with the lowest idel current losses, usaly that number was 1.7 amps with the secondary removed............

Mixtures of rosin and waxes make electrets if melts are cooled under electrostatic stress.

Makes an interesting capacitor that recharges itself. Also great for polarizing diaphragm
microphones.

Yeah, have heard of this method.

Apparently it also works if you make a plastic gel with polystyrene, acetone and Shapelock then heat up to about 75C and apply HV while the solvent evaporates.

I've used bee's wax and the "clear-type" hot-melt glue (ratio of 30:70) & it preformed well.

Can the charge difference between the sides on an electret do any work?
