12 times more output than input, dual mechanical oscillation system !

Nice thread, people.

I found this device rather interesting too and, having modeled it in wm2d, I found myself in a position that I have been in before when looking at bessler wheels and suchlike: looking at models and thinking "If only there was some way of controlling this part of the cycle we might get energy out". This time I managed to see how that could be possible.

The explaination is at http://DeclarePeace.org.uk/jhula/.  Let me know if it excites you as it excites me.

Thanks for that link, pilatte.  Very interesting.  They are working on a much more complex problem than the one I am proposing; predicting wave motion in order to optimise a hydraulic pendulum pump.  That paper has a number of very useful references. Jhula is much simpler and, I am sure, is much easier to analyse and predict than what they are trying to achieve.  I am suggesting that there may be no need for all that input energy from waves but that merely using the latch/un-latch mechanism ('optimal control' is the area of wave power research) it may be possible to increase the energy in the system for no (or negligable) additional energy input.  I think they (as I did for ages) haven't seen the wood for the trees.

I've begun a new thread for the Jhula discussion (http://www.overunity.com/index.php/topic,2138.0.html) so please reply on that thread with regard to Jhula.

I started over with my design (will post pictures soon) - the first try is mostly just to find out how bad my understanding is.  Lever turned out well with very little friction or bounce and adjustable. Seems to transfer all the energy from one end to the other.

Currently, I'm tring to build a very good pendulum with the parts I have. My goal is something that is a couple pounds and requires milliamps. Having the motor on the lever seems to the way to go because of the verticle motion. An external push/pull would have to be syncronized in two dimensions or waste power.

Thinking about piezo electric effect because the lever needs to be maintained within a range because the oscillation are not limited by the dampening of the lever. Why waste this force through restraint? Instead the piezo material will be under pressure (weight of lever and pendulum) and generating power even when the lever does not appear to move.
