[Electric Boats] Re: Displacment



Just for a little fun, Absolutely. LOL

For water to change from potential energy to kinetic energy it must flow downhill. Fortunately there is a space in your boat that is below the water line, the bilge. So, the water must flow in through a below water thru-hull, into your turbine and then out of the turbine and into the bilge.

You might think that once the bilge fills up you can extract no more energy, but we are once again in luck. The water line will have raised on the hull and the bilge is even lower and water will still flow. However, once the waterline reaches the deck, this technique will cease to work.

Remember, no perpetual motion, no free lunch.
