Abstract
Apparatus for harming or killing fouling flora or fauna, for example on boat hulls, comprises two conductors and an AC power source. The first conductor is a conductive coating while the second conductor is a spaced sheet in one embodiment and a grid on a dielectric insulating coating in another embodiment.
Claims60
Apparatus for harming or killing fouling flora or fauna comprising:
- a solid dielectric member;
- a first conductor located on a first side of said solid dielectric member and in contact therewith, said first conductor having a surface to be mounted on a hull of a ship;
- a second conductor located on a second side of said solid dielectric member and in contact therewith;
- and
- an AC power source connected to said first and said second conductors.

Apparatus for harming or killing fouling flora or fauna comprising:
- a first conductor;
- a second conductor;
- and
- an AC power source connected to said first and said second conductors;
- wherein one of said first and said second conductors is bare or has no more than a semi-insulating coating, and the other of said first and said second conductors has on a side thereof to be directed toward water during use an insulating coating to insulate said other electrode from the water during use.
