307200000000 V DC ! sound fun?

those are usually just a little transformer, a transistor and a capacitor

just enough to make a little oscillator that creates maybe 1KV or so - enough to toast some bugs

The name for TV transformers are "flyback" transformers

I made many high power tesla coils when I lived in Canada, and I have to say There is nothing that will insulate that kind of voltage except a large distance between hot and ground. Average distance for 30 million volts is around 150-300ft or more depending on the current. My largest tesla coil put out around 2Mv and ran from a potential transformer 6Kw... 14.4Kv.
Sparks were around 12-15ft at peak. ;D ;D ;D ;D

could you tell me where you got all the parts for the 2mv one.I'm in canada

If you want high voltage for a short period, look at Flyback transformers. (Although you can keep re-triggering them if you set them up right and charge a capacitor for constant voltage.)

If you want constant high voltage, look into microwave oven transformers.

The main problem with the origional idea (Main as in one of many.) is insulation, as one side of the transformer is always connected to 0V and Line voltage, there will be an increasing potential difference between the primary and secondary.

You're right when you say that transformers only work with AC, although you can pulse DC through them at a high frequency.

car ignition coils can be easily used to generate high voltages, though tv flyback transformers are often easier to acquire.
B&W tv xformers are easier to use than color ones btw, which makes them even cheaper and more plentiful for free. I forget the details but the color coils have some sort of (thermal?) feedback circuit and/or multiple primary taps for each electron gun.

microwave transformers should not be toyed with - they only output about 2-3 thousand volts but at half an amp or more! extreme caution should be used if you're going to run a microwave transformer with the original secondary winding in tact. If you want a ton of voltage you should be looking into something like a tesla coil

I second this .. I have played with MOTs as they are called in tesla coiling. They may output 2200-2500VAC but they are POORLY current limited (often limited with a capacitor on the output). I have seen older ones pull 3000W from a single transformer. 2.5Kv @ .650-1.5A is not uncommon THEY ARE HIGHLY DANGEROUS and are to be used with extreme caution. Just like playing with any unregulated transformer (like PIGs)
