how much is it generating coz the one at school generated 600,000 volts and onlyjumped 7cm so this must be generating a realy high voltage

Polycarbonate then

"Spark tube is a 1 1/4" clear plastic tube"
What thickness and what kind of plastic is it? Nice effect.

For fruitful information about Van De Gruff Generator this video will work.
I just wonder why NASA does not develop
a safe source of energy such as this one here and get rid of all these toxics from our life
It is all described in the
top magnetic generator
search for it in Google

@PlasmaStar9 Thank you for your response. I will change a few things around. Very nice arcs!

hey man you should add a water capacitor to get longer THICKER and LOUDER arcs. Costs10 bucks or less and is suuuuuuppppeeerrrrrr easy to build. I have yet to see anyone do it.

What is your discharge wand made of. It appears to be just a grounded rod with a 1" diameter metal sphere on the end, inside a plastic tube. I tried recreating it with similar materials but did not get anything like your discharges. Could you tell me what I was missing if anything.

Discharge wand was a cabinet knob with a small brass rod screwed into the threaded hole to keep the knob pointed forward. Ground wire clips to back of rod. The tube itself is one of those cheap clear plastic tubes that fit over a fluorescent bulb. The problem is that static electricity is very persnickity. Sometimes it works. Sometimes it doesn't. Could be variations in humidity.The tube tends to build up a charge like a capacitor. Try different knobs, distances from tube to terminal, etc.

Can you comment about what materials were used in the belt & for the pulleys? This looks like a particularly successful Van de Graaff generator, so I'm curious exactly how you did it. Suppliers & part numbers would be greatly appreciated!

bottom pulley is1" dia nylon bar stock. the top pulley is 1" dia teflon bar stock. the belt is 1/16" thk black solid neoprene rubber from an industrial rubber supply company.

From Grainger? I've seen that they carry those materials as bar-stock, but at the moment I haven't got access to a lathe -- the only way I can think of to put a hole through the roller properly. Did you think up a clever way to get a concentric hole through the bar, or did you have a lathe handy?

Don't know about Grainger. Actually bought bar stock from a retail plastics supply co like the kind that sells sheet plexiglass. I do have a lathe which I used to machine the top roller for ball bearings and the bottom one for the motor shaft and to crown the rollers slightly. Yeah, you pretty much have to have good concentricity, because the faster you can run the belt, the higher the output. I mounted the bottom roller directly on an upright vacuum cleaner motor for power and speed.
