It is the time to activate the sailboat to reduce the dependencies to fossil energy. Unfortunately no one until I wrote this implemented this strategy. To move the ship is need very high of energy, more ship that using fossil fuel consume very big or a lot of fuel. With sail, the wind are move the ship, the ship only need to power the arrangement of the sail.
With the same principle, a heat pump water heater are created, to save energy. Go Green with sailboat !
