“I’m having a problem seeing how that doesn’t consume as much or more power than it “saves”. You know, that whole law of conservation of energy thing.”
It doesn’t save energy. It gets energy from the motion of air molecules.
Thanks for clarifying. So is it the motion of air molecules flowing across the boat because the boat is in motion (air flowing from front to back)? It seems like that would create as much or more drag than it'd recapture. Or are the air molecules in motion from wind coming from the side?
