Because the sign does not matter. 8) You must have asserted this 500 times without any proof, but it's still wrong. --- End quote --- Sorry I need to give up on you. Not sure how you can get rid of your wrong understanding of physics and be able to start from scratch. It will be a waste of my time to continue to argue with you when you get fundamental things wrong. Unless you understand those there is nothing I can do for you. Sure you can rotate the wind turbine to face the other direction when wind direction relative to vehicle changes and yes you will be able to generate 300 or 400W for 30 or 40% efficient turbine but your vehicle will be slowed down by at least the equivalent of 300 or 400W so your vehicle will slow down. The direct downwind faster than wind blackbird is a very different vehicle. You need to stop and modify the vehicle you can not use the same vehicle for downwind or upwind. But say you take the upwind version the one where propeller is used as a generator and push that to above wind speed directly downwind it will just not work the way you think and it will slow down as soon as you stop pushing. I was thinking electricity is more of your field so how come you did not went with the 200W 20V 10A CC-CV lab power supply analogy. Show me how you can get 30V or 15A without using energy storage. Or how you can get any negative voltage without energy storage. |

But sure. The only thing you have is the wind power, which you don't know how to interpret, and wrongly believe that ground kinetic energy is 0 in the car reference frame. You also don't know how to apply any principle of thermodynamics. --- Quote from: electrodacus on July 12, 2022, 12:51:41 am ---I was thinking electricity is more of your field so how come you did not went with the 200W 20V 10A CC-CV lab power supply analogy.

One long wire is at 20V (it's the wind), another is at 0V (ground). Make a device which goes fast, say 10 times faster than electron drift speed. |

If you use a resistor divider you can provide me with any voltage output between 0V and 20V but nothing below or above that same as you can get a direct downwind, wind powered vehicle at any speed between 0 and wind speed but not above or below unless you use energy storage. And I will really love to see how you can get more than 100% power output after that circuit. |

You did not changed anything other than the way you interpret the data. I will have a voltmeter at the output of the power supply and one after your circuit with both having the negative probe connected to GND So both voltmeter will measure the same -20V no inversion done by your circuit. |
