How to make a spinning pendulum?

  1. Mar 29, 2014 #1
    Probably a stupid question...or possibly one with stupidly simple answer...Could this even work? I have this mechanism that generates electricity when you turn the crank (think Faraday's little doodad with copper wire and magnets) and am trying to figure out how to make this thing hands-free basically...

    Any idea would help, I've been trying to figure this one out for months. Lol. I've finally surrendered.

    Or how would I make the most efficient pendulum, rather?

    You don't need a pendulum, you need an engine. A pendulum can only supply a very limited amount of energy to your generator. If you are trying to generate electrical power then you need some other form of input power.

    If you are trying to build a perpetual motion machine then please review the rules of the forum and the rules of nature.
