hich you
would define conductors and total charge and which would work out charge
distribution for you, this may exist.

How cute, is this what you tried to fly your lifter with?
Of course not.

No, it's just a pin point vaporization and carbonization of skin, the
soldering iron will burn and either leave skin hard, or if hotter it will
make skin slough off so it's quite different.
Obviously if the ma's are too high it is worse and if rectified to DC and
maybe a cap to rectify easily dea

Actually the only thing you feel is a pin point burn and the smell of

If it wasn't for the burn it's not painful though possibly irritating.
Is it like grabbing an electric soldiering iron at the hot end?
I did that when I was 12, believing it ha

Someone posted the idea of powering their lifter with batteries. I'd
like to suggest a MHD generator. It would seem to me that ti would be
lighter, I don't know about the price though.
This is a device several guys on this list could build and test.

Well one could also do what Stephen A. Lawrence suggested earlier.
Put the lifter inside a box and place the box on a
few mA) can be lethal, and hurt a
lot in the very least (feels a bit like having your arm caught in a meat
chopper I was told).
