Electrostatic motor

[PiCéd]

Before today, I did not know that, the Schinger limit is very interesting.

I see that when I clic on the number of the dielectric strength of the vacuum here:
http://en.wikipedia.org/wiki/Dielectric_strength

For a low vacuum it is at least a litle more than 150 MV/M

Here a link to know one of the values of the electrostatic:

Mh, the result of his calcul is false it is 29.47 microamps...
imax = 3.14 x (0.13² - 0.09²) x 40 x 26.55 = 29.47

His wimshurst turn very well when he remove his hand (between 1:22 and 1:31):

If we compare with a simple electromagnetic motor the wimshurst is very efficient, for exemple I have a portable lamp with a crank and when I turn the crank with a good force and when I remove my hand the crank stop to turn lesser than one seconde.
In the video, if we do the calcul of a cap who is:
E=0.5xCxU²
If the space is approxymately 10 centimeters and we have a good day:
100 (millimeters)x3000 (or 3600 volts)
If the layden jars have aproximately 50 or 100 pico farads, whe have:
E=0.5x0.0000000001x300000²=4.5 watts
4.5 watts in 6 or 7 seconds, start to 1:11 finish to 1:17

That sounds reasonable. It might be in fact more efficient theoretically, but unless these watts can be transformed into watts useable by our tools, it's unfortunate. I mean the Wimshurst doesn't even achieve a glimmer on a 80 milliwatt bulb, which a simple bicycle dynamo does easily.

On the other hand, a Wimshurst or Bonetti or VanDeGraaff can light up neons and gutted CFLs easily, where the simple bike dynamo doesn't produce even a glimmer. Apples and oranges.
