funky little thing isn't it?

There is water inside the pendular rod?

Hmmm ... The chaotic motion creates chaotic distribution of weight inside the rod? The water moves chaotically, and its weight distribution is always chaotically changing ?

This thing stops moving??

I think I can see it.  When the right side is down far enough the weight of the left side (empty of water but high) has gotten to the point where the middle short leg with a weight is high enough on the left that the combined weight of that plus the empty left bar are greater than the right side with water and it starts to swing the right side back up.  As soon as it approaches level the inertia of the water flows to the left side and the left starts it's downward run until the weight in the middle is on the right far enough to where it starts the sequence all over again.  I would guess there is no real useful power there since it depends on a very fine balance.  I think even a large device would yield very little power.

how does this thing work exactly????????

any diagrams/pictures/drawing/schematics?

i thought it was an odd contraption and thought i would share it


i think it pulses water and somehow the momentum is maintained even though the lever is balanced in the absence of water

i liked how pulsing water on the downstroke side to manipulate a large lever was clever, i dont think it was intended to be PM,

my intentions were to provoke thought

look at this little piece of information that i found, too bad i can't read the whole thing.

The way this works…It looks as though it has two water spigots
at either end of the (generally but not exactly) hemi-circular
track. There must be a big drain port at the bottom of the track.
The horizontal rod pipe is generally in balance with a small
pendular balancing weight below the center that will force the
rod to horizontal, unless it is being actively unbalanced by
water going into the pipe. This weight maintains the extra
momentum. Water goes into the horizontal pipe only when
it is at or just below the spigots. When one pipe-end goes
above its spigot - it is not going to come down for a while.
Air currents cause dollaps of water to go into the pipe
somewhat at random. This is what causes the chaotic
attractor of the timing motion in the device.

so when water goes inside the pendulum it causes leverage which in turn pumps water from the center of the pendulum's pivot point back up into a reserver which then leaks water back into the pendulum? this keeps the system going and going and going...

what do you guys think?

Recycled water?...From the look of the masonary behind it...proly,
Advanced open loop water recycling from an underground mains
leak.  ;)
