Super simple high voltage (try it!)

You're both right; a simple DC-DC converter works with a single inductor, but when you want to get into serious voltages, you need a transformer.

As Turbosuper puts it, not in the case of the boost converter, which makes the boost converter very space efficent - and it's electrical efficiency isn't too appalling either, I've seen them get 80% efficiency on a boost of 12V up to 300V.

Now, this isn't a boost converter, but it does work on the same principle as what the OP has built - just on a tiny scale, for scraping all the charge out of a "dead" battery, and I thought it might be interesting to show you, that is if you've not seen it before:

Does that thing kinda look like a big cat to you?
