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

Have you seen the latest article on Barrett's replication of Milkovic Ideas!

He has achieved the rotation of a bycicle wheel at around 100 RPMs with a power sustaining impulse (for the pendulum) of 2 watts. As the video shows the wheel with a lot of magnets attached, I bet the next step is puting some coil around and generate power output, let's hope he achieves self sustaining, it looks really promising!!!

Lol, I was just trying to post the same thing. Looks like you beat me to it. Yep it's looking pretty good. I'm not sure what he's using to drive the spinning weel on the last rig, but it looks like he's only transfering power on either the down or up stroke. This progect really needs specifically engineered parts, including a concave and convex rack and pinion to transfer torque to a double ratcheted flywheel on both the up and down strokes. This would help maintain the momentup to extract useful power.

cheers,
Steve.

hi all,

Regarding ratchets and things, i feel it would be most efficient to use industrial one way clutches as these have almost no lost movement, also with two clutches and two gears you could utilze both up and down motion...


have fun

Hi all, this is my first post but I'm here long time ago.

I have made a power study and here you are the results. All is done by simulation on wm2d.

I have simulated the hand giving a impulse to the pendulum by a motor and I have reads of power in each impulse.

Because we can have reads of springs power I have used a spring as our generator in the 2nd stage oscillator.

I compared power in and power out.

Test to put air resistance 0.1

Judge by yourselves.

I made another setup much more intuitive.

Now the hand stroke is simulated in another way.

Have fun!
