I think it is a good idea, although it could demand quite a bit of power.
As a possible refinement, might high frequency or pulses work better than
DC? It would be fun to try this, pleasantly dangerous. Any
electrically-minded people on the Sanet?

I turned up these papers on Agricola, but they didn't have abstracts.
