  • Is a Van de Graaff Generator no more dangerous than rubbing your feet on the carpet and touching a door nob, or can it cause serious damage?

  • @blanknot It's certainly possible to build one that would be dangerous.

  • I wonder how this would work in low gravity or vacuum, or both.

  • @AnubisEye009 Low gravity won't change anything and it should work better in vacuum.

  • the belt whch u hve used iz of whch material.?

    wot else cn v use.?

  • @MegaTeenprincess I believe that the belt is latex. The materials you can use depends on what you choose for the rollers. Check the triboelectric series.

    Imagine how difficult that would have been to understand if I hadn't actually used all the letters in the words...

  • Woow thats awsome

  • @JeffersonLab It wouldn't work under vacuum due to the lack of a medium for coronal discharge. For optimum results one would place a VDG or better yet a Pelletron in anhydrous pressurized SF6.

  • @MegaTeenprincess The tube is just a tube. Don't think it has an official name. Stand-off tube, maybe? Isolation tube? It's job is to insulate the charged dome from the ground. It doesn't need to be transparent. Regular old PVC pipe would be just fine. I think ours is acrylic. As long as it insulates, it's fine.
