good to see you are on the mots.... =) good luck
post some more about it...
One thing I'm doing with my MOT is building a voltage multiplier. This is a simple diode/capacitor circuit which will increase the transformer's output voltage. Here's an example of the circuit:

Here's a typical waveform:

Stan Meyer mentions DC ripple voltage so I'm going to see if this waveform can charge a cell. If it does, it may turn out the be the cheapest approach. With a multiplier, the ripple at a single capacitor can be extracted. Additional circuit elements can then be included.
