It is a good software. It show how my idea failed clearly.

Successful mistakes

There is a point between 10 and 15 seconds of your video where the flaps? are swinging to and fro between 6 and 8 o'clock on the wheel. This is enough to add energy to the left side of your virtual wheel, and is why the wheel starts spinning.

No such thing as a mistake, only a lesson learnt

simulator

Here's one I slapped together to show it is indeed the centrifugal force which tips the balance.

Obviously there's heaps of friction issues in this setup. Levers or latches would be better.

The swinging-away energy could be doing something. That would then be centrifugal + swing-away. If the swing-away reduced the centrifugal that would be bad so maybe a way to use the return energy swing. Get the maximum centrifugal + maximum return: pump-pump, double hit.

bravo Inquorate

very promising

perhaps adding heavy ball bearing at the end of the levers to reduce friction and increase inertia

thank's

Inquorate,

I think you are on the right track! My only suggestion is to damp the swing by the 6 o'clock position, so the downward centrifugal force generated by the swinging weights will not start working against the forward clockwise motion of the wheel.

Levers and latches quickly brings you back to the design I propose in my Mechanical Engine article. Your design should work too, I think. Much simpler too.

Additional weight

I don't know if the software is faulty, but the flywheel is a virtual 28kg and the little pendulums are only 60grams. Any more weight and the friction becomes too much.

What the?

[Inquorate]

Just a light-weight

I've been trying different setups last two days - latches too fiddley on the software.

But results are promising enough to build.

Might even put the veljko oscillator on hold for a while.

Nice work Ben. Mine would still need an enforcer to either force the flipper either in or out. Maybe I can do it with L shaped weigth or with weight connected to non elastic string. Without it it would go to equal position






about weight, can't you force it? try reducing static and kinetic friction too.

Hi Inquorate,
I agree to woopy's comment.Thanks for showing this.
I think a main prerequisite for this to work is in the eccentricity of the guiding 'circle'. And the simplicity of your design might make this work in reality.

See also drawings of patent WO2008097402A2 for reference here:
esp@cenet - WO2008097402A2 Mosaics

but obviously your design is much simpler. Great.

addendum:
I don't think the oscillation of the pendulums gives the driving force in Inquorate's design.
I think the design works because of the following effect:
A part of the weight of those pendulums which are at positions between 9 o'clock and 12 o'clock is supported by the 'eccentric guiding circle'. So not the full weight of these pendulums loads the wheel. So there is a weight difference between the pendulums on the right side of the wheel and those on the left side.

Update

According to the simulation software, adding wheels to the ends of the pendulum make it work reeealy well. It goes too fast. Lots (more than 8) little pendulums that are light, and a heavy flywheel work better.

Get the balance wrong, and it goes backwards.

Anyone who downloads the program who wants the file for setup I posted in my youtube video just email me.

Very fiddley.

Now to contemplate a real version. Thankyou Sucahyo for the software link. Saved heaps of time

[woopy]

very good news Inquorate

i will also let my Milkovic sideway and make a replication of your wheel

i have e.mailed you today

looking forward for a real thing i hope that "working model" works correctly

thank's to you and Peter Lindemann for the pendulum solution

Over-Speeding is what you want!

Inquorate,

Heavy pendulums is what you want. The "over speeding" problem disappears when you ask the machine to turn some "constant load" device. Bessler ALWAYS ran his wheels loaded with water pumps and stamping mills. This is part of the balance of the machine. It has to be able to "run away" unloaded if it is going to have any power to deliver to a load.

For your first prototype, a small electric generator running an incandescent light bulb will provide a constant load.

I am thrilled with your solution. It should be easier to build than my design, since it does not require a cam, or a latch and release mechanism. Plus, it gets more swings per pendulum per rotation.

Great work!!!

More thoughts

I've worked out why heavy pendulums have been giving me bother, and why my virtual wheels want to run backwards.

Drumroll

All so simple in retrospect. The pendulum becomes weightless at the apex of the swing. If it's heavy it will have a wide swing.

I haven't tried it yet but a spring / rubber stop near top of pendulum to stop overswing (careful not to limit necessary ability to move as wheel turns - so just one stop not two) and return energy to pendulum so it spends more time in extra gravity state.

The one I made (but didn't save - Aaaaargh!) that over sped had a ''wall'' on both sides of the wheel; I was trying to stop my pendulums from spinning right the way round in a circle.

It should be possible to make one that has 'eccentric wheel' in upper centre of flywheel, not to one side. on the bottom, damp the swing with a slight touch to the wheel on the end of each pendulum.

This would run either direction but not as fast.

And that is exactly what bessler did, to prove that it was not using clockwork to run.

I knew that when I figured out how to make it work both ways but slower than another only able to run in one direction - both using the same principle to turn - that I would have it figured out...

Hot diggidy.
