  • Alternator + Electric motor + 1 good push = Never ending loop of energy.

    Problem?

  • @AngusTheCow95 alternator cannot possibly exceed 100% efficiency, neither can the electric motor. energy in (to either) is always less than energy out. therefore, not possible. (although I've had people pitch this idea, and similar ideas to me many, many times)

  • @AngusTheCow95 the problem is that a part of the energy will pass in a form of heat and friction so it cannot be fully efficient

  • Can you still take your AC apart and change the brushes? 

  • @Filmaker25 depends how long your engine runs. If everything else is perfect, your brushes wear out. The alternator is spinning regardless of whether your car is moving or not.

  • nice music in the bg thanks for the vid bro

  • @AngusTheCow95 Troll physics, = the only physics

  • do all alternator comes with a regulator?

  • How many miles should you get from a alternator?
