Stinky worked that out yesterday in terms of power. 4GPM requires 21kW. That's well within achievable range at the amplified 3000V and 30 Amps, providing 90kW. My question still remains. Is there a reason this would not work with a signal amplifier? If so, what reason? Too much heat? I think we have some chemical engineers who know how to work that out. Our goal is heat, after all. Seems from that article that 3000V is what a microwave oven is already achieving. That's where the number came from.
