    That makes sense, except the collection of the energy can be less than the energy expended, like an automobile or wind turbine. Then it could be a perpetual machine.

    It would be like this:

    Energy in => convert to a gear that makes it way more energy => store energy, repeat.

    I must be missing something.

      The collection will always be less than the energy it takes to generate it. There no magical gear or trick to change that.

      nah, see, a gear is basically just a fancy pully. it can make it easier to pedal up a hill, but only by making you have to pedal many more times to do so. each turn of the crank arms takes less force, but you have to do it many more times. it isn’t actually reducing the energy requirement, and it isn’t multiplying your energy input.

      what you’re describing here would be some kind of magic.
