This is how I have it as well.. Tesla also did some very important work in
radio. He also never used a napkin more that once (and ate with a heap of
them next to his plate), and also ate alone whenever possible.. I still have
a Tesla transformer on my cupboard, which generates sparks of approx 30 mm
that don't shock you even when you allow it to jump straight onto your
finger. That was Tesla's comeback to Edison's comments about AC.. The tesla
transformer generates a very high frequency alternating current at a few
million volts. The high frequency causes the current to stay on the skin, so
avoiding electric shock.  Of course this counter argument was as silly as
Edison's original argument against AC.  All in all Tesla was right though
and AC wins out by far because it allows easy use of high voltages for
distribution, and since copper losses go up with the square of the current,
the effect of lowering the current in power lines by increasing voltage is
dramatic..
