  1. It's being used for some long-distance high-power transmission. Also for transmission between AC networks that are not in synch with each other.

  2. A commenter says the military uses five-phase generators. There was no explanation of toward what purpose.

  3. There are vids on this platform of electric arc furnaces running and the cables to them are dancing.

  4. The vid says that.

  5.  @JuhoJohansson-bz3jb  Those glow materials are "phosphorescent" if they have a slow decay.

  6. Thanks for saying "rotational speed"; some erroneously say "RPM".

  7. FULL BRIDGE RECTIFIER!

  8. Aren't Teslae charged with DC? Or do you mean the input into the (stationary) charger?

  9. Reduce the load resistance.

  10. No, wind-turbine generators use those neodymium permanent magnets. Dependency on rare earths can be a problem in case of lack of international co-operation and trade.

  11.  @davidbrayshaw3529  How would you get current?

  12. If you are going to distribute power that way, how do you step down the voltage for loads that need lower voltage, e. g. almost all loads?

  13. I suppose it gets a significant efficiency improvement as compared to rotary converters.

  14. Wouldn't the two phases be arranged orthogonally to each other?

  15.  @matthiaslipinsky501  I don't refer to any actual use of two phases. I refer to the hypothetical use that you mention.

  16. I'm thinking that if any are steady, it would be because of the electronics used to drive them.

  17. If you take away some of the energy to power the house, the amount remaining in the apparatus is diminished, so it slows down.

  18.  @luciusdouglas5807  , size doesn't change the fundamental argument. Look up "conservation of energy".

  19.  @luciusdouglas5807  Howsoever you may set the variables, it will still be the case that the rotating machine is storing a finite amount of energy (in joules), and you are bleeding away some of it (in joules per second) and so the amount in the store must diminish. And when it reaches zero, it can't go any further.

  20. The relationship is that in the engine and in the motor, rotation is being produced from individual pulls that don't follow the full rotation. The effect of a coil and a magnet is similar to that of a crank and a piston rod, in turning push-and-pull force into rotation.
