Re: [TCML] Off grid, medium size, 12V battery powered TC

Jonathan,

A small battery powered 12v DRSSTC will easily give 2' arcs.
I have a (hand held) battery powered DRSSTC that runs from 10 x AA (MIMH) cells that will give 1' arcs. At full power it draws approximately 3-4A
The Coil has a small inverter that takes the 12v up to around 350V, from there on the coil is a standard DRSSTC.
Assuming scaling up the design will not incur any losses, roughly 12-16A at 12V should give you 2' arcs. Admittedly at a slower repetition rate than you would get from a classic design.
To me that is much easier that the mechanical voltage multiplication method described, but I'm biased being an ex-electronics engineer.
