The only down side is that you can't reverse the currentThere were some cheap ionizers on ebay a while back, they might be a good start too. For safety I'd aim for low voltage powered HV devices. I'd be very wary of using an NST. In a fault situation or a HV DC discharge from the VDG to the NST output, they could create a high current path to whatever the VDG was connected to, or arcing to at the time. This could easily be lethal.

Oh I forgot to mention, any good suggestions for current limiting here? 30ma is far too much for a VDG am I'm sure most of it's going to be wasted anyway. Do i need a good old variac or some other cheaper alternative? Will a light dimmer really work i this situation? Thank you!

Specifically up to 15KV at 30ma I would assume I need to account for RMS so probably around 20KV. I think I can get away with just one for half wave and maybe a cap for smoothing it a bit, but that would need to be a pretty decent cap to deal with 60HZ at that voltage. I'm using this to build a HV DC fed VDG does anyone have any hints or suggestions? I know I can find both diodes and caps in microwave ovens but its a pain to pull them apart and they are commonly too low voltage. I have found a few online retailers just wondering if there may be an alternate source, or anyone have some for sale etc. Thanks for any help!
