The basic design of this induction-type electrostatic generator came from a small book on this topic that I read many years ago. I designed and machined all of the wood, plastic, and metal components myself but it took one of my brothers, who is a top notch electrical engineer, to figure out how to make it work and fine tune it. The biggest spark it has ever made for me was 3/8” long which equates to about 5,000 volts. That’s really not much as sparks go but its enough to do some fun experiments, like light up neon bulbs without any wires or making insects feign death. Making it work is just a matter of turning the shaft so the brass spokes (36 of them) pass between the brass plates. It takes only 30 to 120 RPM to do the job, which can be done easily by hand, but it is possible to mount a motor to it if desired. Incidentally, spinning the shaft faster doesn’t make it generate bigger sparks, it just generates them faster. Also, we’re talking here of static electrical charges, not the same thing as AC or DC electricity.
The price listed is two thirds its actual price. I must list it this way to foil unwanted inquiries.
This generator is 18” long, 11” wide, and 20” tall as assembled. It is actually in inoperable condition due to its age and thus no longer for sale but I am making identical copies of it as well as a "new and improved" version which should be available for purchase in a few weeks.
