That's really neat all right!

I especially like the use of the dollar store materials. Even neater would be to get rid of the commercial capacitor and run it on a simple Leyden jar made from a plastic bottle and some foil. The magnetic bearing is a nice touch. I've used needles and small glass test tubes in much the same way.

Even neater than that would be to get rid of the power supply and charge the Leyden jar with an electrostatic generator of some kind, like a small VanDeGraaff machine, also made from dollar store bits and pieces like steel bowls, rubber bands and so on.

The fact that you don't need wires, magnets or precise machining means that devices like these _could_ have been made and used a long long time ago, even perhaps "prehistorically". There are people who think that the Ark of the Covenant could have been an electrostatic capacitor, and the pillars of the Temple of Solomon, electrostatic generators.

There are some easy enhancements that could make LidMotor's esmotor run even better.

A little VanDeGraaf machine powering another kind of "cyclotron" free-ball motor, showing some interesting effects:

The ping-pong balls are coated with a conductive paint containing nickel, that can be found in electronic supply stores. The VanDeGraaff machine uses a little motor from a tape deck, running on a 12 volt battery, and an ordinary rubber band as a belt, with rollers made of teflon or Delrin at one end, and brass or aluminum at the other. Steel bowls are from the Chinese restaurant supply store. I found that the bead chain makes excellent "wiring" because it is large-diameter so doesn't blow off charge like a thin wire would, yet it is conductive and flexible enough for the very high voltages you get. What's a few ohms when you have 50 kV to play with...



If anyone still has CRT monitors, you can get enough power to run motors like LidMotor's by using some foil tape to attach a conductor to the screen. Oleg Jefimenko shows how to make electret "slot" motors that can be powered from an antenna lofted by a balloon.

Electrostatics are great fun... and yes, you can get zapped from the storage devices like capacitors. Commercial caps can store a heavy charge for a long time, too....

(All of it )

Yes, he started with a soft ball of sorts and a franklin bell a few videos ago.


And a bug zapper tesla coil...


I actually have a van de graff now; it's a hand crank... but, was able to put it across a spark gap with a secondary coil .. and have a bad tesla coil   Interestingly while it wasn't sparking but was charging the neon would continue to spark... so there was a lot of leakage.  Really need different stuff than stranded wire to use static electricty well.... like if I attach a meter probe with a pointy end on the ground and charge the ball at all, it glows no the top from 4 feet away



Then I read more about tesla's obsession with short sparks; so there is a flowing fluid dense/viscous? dielectric (oil) so it cuts the spark extra short....


TO the point that any back EMF from the field collapsing from the coil can't return...
