Spring Generator Motor on YT.

Found this vid on YT. I know a lot of fakes are out there, but something is interesting about this...

Notice the direction he spins the wheel. When the crank pushes down on the spring strip, it makes first contact on the far left end, where it would be easier to do so. Then when the crank is on the upward swing, the spring should have more torque to push it up at that point, more torque than it took to push the spring down.

Thats just what Im seeing so far. And the adjustable weight on the spring changes the resonant vibration of the spring?   

Just something to think on.

You are absolutely correct on what you are "seeing so far".
However there is more: much more you are not seeing that is happening and can be done with this. Some early EN-GEN designs I built use somewhat similar concept(s) with "continuously variable fulcrum" levers that did work to do just what you describe.

If you study it you should find it is (in a  sense) a mechanical version of an airfoil in operation.

You can make it better by using "180 degree twin cylinder"  type crank shaft with ball bearings for the rollers on BIG leaf springs or levers with coil springs from car/trucks, or whatever. Attached is a photo of one of several 180 degree cranks I built and tested.

It works but is not "practical" and it is ancient history.

Not exactly the same but the concept is, and it is adjustable.
Can you guess what it does?

Hi Vince,

I cannot resist to answer with this question: Does the flywheel come to a halt soon?

My guess is the flywheel stops fairly quickly.  The big difference I see is the motor in the video has the cam only hitting the spring at the bottom of the revolution.  Maybe for 90 degrees or so.  Yours appears to have the cam in contact with the spring loaded arm for almost all or maybe even all of the rotation of the flywheel.  You need a stop on the arm to limit the amount of time the cam is in contact with the arm.
