    I mentioned that in post #2.

    With small surplus components it should not cost a lot to make a good experimental setup.

      Would anyone be willing to draw up a sketch for me?

        nickelec:

        A motor/generator like the following is quite inexpensive, and might be good for experiments. It is a permanent magnet field type. Might require external blower for cooling, especially for low RPM, as do all motors.

          When I made the last post there were 12 motors, now none.

          If you search for treadmill DC motors you will find many. Look for low cost, you don't really need quality. Your experimental service will be very limited. Use one as the motor and a second as a brake load (generator to a resistance, light bulbs).

            There are 4 different treadmills on my local Craiglist today, all in working condition, totally free to whomever comes to haul them away.

            I wonder just how many of those things are bought, used for a week, turned into a clothes rack for a few years, then junked. I'd bet it's 90% or more...

              I bet they'd see much more use if they had to be run to power the television.
