Sorry, in the case of "sail" boats, I worded it poorly before. Wind turbine-like "sails" could act as a propulsion source when the wind direction is correct, and generate energy and funnel the air into the CO2 -> fuel machine when the direction of wind is non-optimal for propulsion. I agree in all of the cases I mentioned there would always need to be some energy source. |
