quoting note1ydw…5euyPower density 10-100x greater but for field propulsion maybe more is needed?
Great idea! sstackmore (npub1xsy…scll)
However I must warn you that working with high voltage is very dangerous. Must not be taken lightly.

The first step would be getting a ultra precision scale.
One of our first goals is finding an easy to reproduce way of producing high voltage at extremely low frequencies.

We've been experimenting with expensive wave generators, but that is not easily reproducible. We need something better (cheaper.) I'd suggest looking into Van de Graaf generators.
And again, take proper precautions, please.
