Jhula principle - increase speed by applying brakes.

Yup.  Not only that but you can change the weight of the pendulum and it still works.  I will have a play with pendulum length and the bracket length too and see what happens.

What you seem to have done with the spring is to bias the over-centre to one side; just what was needed.  I'll play some more.  Very exciting.

You may not need to...

Scratch that last post... The sim stopped after about 4 minutes.
Add a rotational load though! Good way to simulate power
extraction when your improving on the design.

I hope this works even half as well in real life as it does in this sim.
Free energy via an unbalanced gavity wheel would be pretty neat!
(I really hope this isn't a glitch of some sort...)

Well Dingus, I just shortened the pendulum and increased its weight slightly. Excellent result; it just keeps going.  We already have some load in terms of air resistance.

wm2d starts to look like a prophet of the free energy age, eh?

let's hope nobody closes wm2d company after some of you recover a working free energy device... If gravity is really the same as DC current flowing from ground to sky... Then I believe there should be no problems creating a free energy device... probably if wm2d shows a constant movement..in reality it can turn into acceleration. (just a bit of fantasy, sorry
