Re: Hand cranked Tesla Coil?

Hi Matt

brief trawls through the vast InterNet, source of all that is
fully-referenced and indisputably true, suggest sustained human power
outputs in the range of about 150-200W, for average mostly-in-shape cyclists
and so on.  Peak outputs (like in an explosive vertical jump), or
non-sustained (e.g. sprint until you're completely exhausted) are obviously
higher.

On the assumption that you'd like to run your coil and then still have some
energy left to stand up and pack your gear away again afterwards, 200W gives
you 1.6A at 120V (also assuming your old bike is frictionless and your
dynamo converts all of your pedalling energy into useful coil-running
electricity and so on)

Hand-cranking output is suggested to be lower again, more like 50W.  That's
only 0.4A at 120V.

Looks like you could definitely get _something_ powered, but probably not
all that impressively.  Probably enough for a little 4kV NST coil though?

cheers

Mike
