So they tested it in a lab and came to the concluision that you need 6kV/cm to sterilize water
. That would be 600kV for a 1 meter boat, or 6MV (6 000 000) volts for a boat of 10 meters. Does the bright spark anti fouling
system come with a nuclear power plant
? That would at least explain the prize.
Well, they actually talked about sterilizing the water
and I imagine that sterilizing and just preventing growth are two different things. To be fair, the deal with the bright spark is supposed to be the copper rods and not really the electricity. I still don't think it works though.
