Spark gaps are cheap and effective, just have to do a little math. A common meter wouldn't work.

We're looking at hundreds of microamps being supplied at hundreds of kilovolts. Highest number output voltage I found for a machine like this was a sector less one (a bonetti machine) which was 6 megavolts.

The other thing is that the power may not necessarily be useful in equipment that was designed for high amperage and low voltage.
