I think we are all resigned to that now, but you keep spouting all this wrong stuff and that needs to be corrected or it gets perpetuated as fact (on the basis that no-one disputes it). --- End quote --- I'm not talking about the flywheel effect. I talking about the pressure differential energy storage and that is fairly large. If you agree with the fact that there are more air particles on one side of the propeller than the other side while propeller rotates then you agree that there is a pressure differential and that contains stored energy. You can only argue about the amount of energy stored there but I already showed a few post back that is more than enough to accelerate blackbird to 13m/s (the speed record). You are not offering facts just strong opinions. |

--- Quote ---Say your vehicle was stationary first ball hits one of those sails. What happens to the vehicle and the sail relative to the ground ? What direction do they move relative to ground ? --- End quote --- It would move the sail and thus the vehicle along a little bit, no? |

He specifies that sail moves in opposite direction compared to vehicle in both cases relative to ground. That is only the case for a direct upwind vehicle tho he tries to explain a direct downwind one. |

If the ball hits the sail what is there to stop the vehicle heading in the opposite direction? There are no balls hitting that, so the only force is on the sail. But also doesn't it depend on the gearing? That is, the sub-question is how far the vehicle moves compared to the sail. |

Before any discussion can start we need to decide if we are talking about direct downwind or direct upwind version of the vehicle as you can not use the same vehicle without modifications to do both things. |
