BCCs: FYI Note: If you look at nothing else - look at the picture at http://www.coe.ufrj.br/~acmq/graetz17.jpg - water in, "Lightning" out. 500+ links to hundreds of electrostatic machines (mainly generators) of every conceivable type and many inconceivable types. Friction / tribolectric type, influence type, other (probably) ... Many examples of machines built by page owner * http://www.coe.ufrj.br/~acmq/electrostatic.html * *List of 122 related papers.* With & without links * http://www.coe.ufrj.br/~acmq/epapers.html * *______________________________* One of my favourites since I met it with due astonishment 'some tears ago' is "Lord Kelvin's Water Machine" Look through the machine and papers for an ideaa of what it is and how it works. The ONLY parts are falling water droplets and some metalwork interconnected electrically in arcane manner. Water falls, without touching metal. 'Lightning' jhappens. One of these days I must build one - tin (or Al) cans and random copper wire would suffice. Kelvin: http://www.coe.ufrj.br/~acmq/graetz17.jpg Same principle - arguably not as much fun as Kelvin's toy: Sand can be used :-) On a Modified Water-dropping Influence-machine By Professor WILVANUS P.
