Where have the electrons gone? |

Why with 100W brought by gears and 1000W in wind, I can't get 300W in propulsion? --- End quote --- You have two choices a) Use the entire 1000W from wind as propulsion directly best case if what you want is to accelerate the vehicle. b) Take 100W at the wheels so 1000W - 100W = 900W of wind propulsion plus the 100W * 0.7 = 70W from propeller total 970W worth of propulsion. The b) assumes a 70% efficient propeller and assumes non compressible fluid. |

Also how can anyone understand any part of physics if it ignores the law of conservation of energy. For the stored energy (in a capacitor) to do any work it requires a conductor to connect the two regions with different charge (the two plates). The electrons can get there faster or slower depending on the conductor resistance so low power for longer time or high power for a shorter period dissipated in the conductor as electromagnetic radiation as charged particles (electrons) interact with the conductor lattice. Since conductor has thermal mass (another form of energy storage) the energy will not be radiated as electromagnetic waves immediately by the surface of the conductor but it will take some time after. This radiated electromagnetic energy by the conductor is in the form of infrared photons. Unless the temperature of the conductor gets high enough to radiate photons in the visible spectrum or even UV. |
