Re: mist maker / electrostatic motor

I forgot to mention the vacuum cleaner VdG I saw built by a "gentleman scientist" in Sta.
Barb. back in the 50's. the "belt" was mica chips recirculated by the wind created by the
vacuum cleaner. Since that was ~45 years ago, I remember no details. It did work "well."

bc

P.s. You all know about painting systems where a charge is applied so the paint will better
cover uneven surfaces, etc.? In the research dept. of the Fredrich Listz school (National
Railway School) in Dresden (DDR regime), one of the engineers showed me the system he was
developing using triboelectricity so an HV P/S was unnecessary.

Wm's system is not "up", so I wasn't able to check if he had a vacuum cleaner VdG.

Here's a question many of you (I presume) know. If I'm correct in assuming that the
charge ferried up is generated by the separation of the belt from the bottom pulley, what
is the purpose of the bottom set of needles?

In the tabletop VDG machines I've seen, the rollers act as the "cake" of
an electrophorus, while the comb acts as the grounded finger. The moving
belt acts both as the metal electrophorus plate, and as the wool which
charges the cake. Once charged, the roller can function continuously
without needing any further charging. The charged roller induces the
combs to spray charge upon the belt. Or from another perspective, the
grounded comb is trying to discharge the plastic roller, but the
insulating belt keeps intercepting the flowing charges.

Here's a diagram:

Note the photo on the above page. I can only perform HALF of the hair-
raising demo nowdays. :) But I've achieved such an advanced state of
enlightenment that under high-field conditions, orange rays shoot out of
my forehead.
