Ralph,
The ni-cad battery to inverter to HV setup and then a standard
spark gap TC as you describe are the way I would go. I was toying
with the idea of making a small Tesla coil on an aluminum widebrimmed
hardhat that would operate off gel-cell rechargeable batteries in a
belt pack for someone to wear at nite-time festivities. With this
device on your head you would not be considered outside the realm of
normal
at a place like the Dayton Hamfest! Coupling this to a UV lamp on
the same hat would make you *valuable* as a mobile electronic bug
zapper to attend nitetime parties, etc.
