This ship, designed by a German, is propelled by the wind blowing against the two strange towers.
These towers are rotated by a motor with the result that, according to the Magnus law, the pressure of the wind becomes greater on one side of each tower than on the other, thus tending to move the ship.
It seems hardly likely, at the time this book goes to press, that this application of a formerly unused physical law will revolutionize the propulsion of ships.
