Hi All,

This kind of bird has been around for a long time as a novelty.

I ran across these giant drinking birds and thought they might be useful for over unity or free energy.

They work off heat transfer and the world is full of that.  Connect the bird to some  type of clockwork to extract its
motion power and  we could make a perpetual motion device that is useful and would run forever.

All the fluids necessary to build this is a chemical and water.  Hardware also.

Any input or has an attempt been made in this direction already?

There are pure evaporation motors like wings example that seem to use folding and unfolding paper
or sponges and the likes of that paper water wheel. Then there are pendular heat motors like the
Dipping bird and Rotary motors like Minto's Wheel where evaporation plays a somewhat secondary
role to the thermal effects.

The Dipping bird uses  DiChloroMethane   -  CH2Cl2   as a working fluid.
Outside in warm climates propane can used for Minto's Wheels.

Here is the famous article that uses lifting weights against the birds energy;
This works a lot like the paper and BB engine in magnetman's  video post, more than I
would have expected. (how about a drinkingbird smot "ball-runner lifter")?

Web Link - A famous Donald Rathgen magazine article about a dipping bird mechanical drive;

The following is a failed attempt at a multi-segmented dipping bird vortex engine. I bring this
up because it looks like if he had made all the birds upright in alignment it would have
worked nicely as a multi-segment pendular drive.

What I think would work to is take a cross-section of a dipping bird and
cut that into a piece of Lucite plastic. Or 3D-print the plastic cross-section.
Then seal both sides with flat plastic Lucite. One could string a bunch of
these continuously on a steel rod as an axle. This all continuous dipping
bird might dip some weight of methylene chloride. One could insert metal
hardware for use as heat conductors.

One may be able to straighten out what is wrong with the vortex drive version
of the dipping bird. - Then add some hybrid permanent hybrid water batteries
and a Bedini magnetic drive and you could be all set. If one could run a basement
water condensing unit one then would have a partially thermal overunity device.
This would make a water-added crystal battery system make some sense.

Rotary Minto's Wheels

A working bathtub sized wheel, looks to be driving a small generator,  Minto's Wheel;

Qwert,

Yes, that is correct. It takes a significant amount of energy to get the heat to flow through the
heat engine so that a very small amount can be converted to upgraded energy. This is because our
low temperature reservoir is significantly far from absolute 0. The efficiency of a heat engine;

Eff = (TRhigh - TRlow)  /  (TRlow - TRabs0)         where Rabs0 is ~300C deg. down, or ~500F deg. down


:S:MarkSCoffman

The bird works as a regular heat engine: no work without temperature difference, no matter what kind of material involved inside: more temp difference causes this mechanism more efficient, less temp difference - less efficient, no temp difference - the bird stops its operation.

Traditionaly "smart sceptic" guys forgot mention that "no temp difference" is a scientific abstraction which rarely seen in real life :-)

"Smart sceptic"? Do I say "it does not work"?

No, you not. But overall impression from your post is that "it does not worth anything".

My "strange" observation: not even ONE project which started on this site is successful. Most discussions (though their projects are still not successful when it comes to OU claims) come from "outsiders'" projects, those who relied on their own knowledge when they started theirs. My scepticism comes from this observation.
