So, if this downward bias is all about electrostatics, how many volts per kg do I need to make a 1 kg object hover? Are we talking van de Graaff levels, or full-on Skies of Arcadia moonstone-tier Tesla fields? Asking because I don’t have a spare 700 megawatts lying around.

Electrostatics would need ~0.1 C or ~10 MV/m to replace g for a 1 kg mass — impossible in air (it would spark long before).
