Jhula principle - increase speed by applying brakes.

Ok builders, here is a very simple version of Jhula; somewhere to begin.

1. The crank axle is fixed to some solid point: a wall, frame or stand etc.
2. The crank is free to rotate anti-clockwise about its axle.
3. The pendulum axle is fixed to the crank.
4. The pendulum is free to rotate clockwise about its axle.

If you grab the freewheel hub (freehub) from a bike you can use it as the axle.  The chain sprocket is able to turn anti-clockwise with respect to the rest of the hub but not clockwise.  So fix the crank to the sprocket and the hub to a fixed point. Take another freehub. Fix the sprocket to the crank and fix the pendulum to the hub.

What are the appropriate sizes? I don't really know.  I would suggest that you make the crank and pendulum as heavy as you think the hubs will withstand; remembering that they will be rotating so you will have to take into account the centrifugal forces involved and that the crank hub will have to handle the combined forces of the crank and the pendulum.

What lengths? I haven't found an ideal yet.  There is a relationship between the period of the pendulum (how long it takes to swing from one extent to the other) and the distance between the two axles.  Different combinations will behave differently.  The machine will run overunity when the acceleration due to gravity is greater than the decelleration due to friction.
