Have a look at this:

Okay, not directly powered by gravity but evaporation of the
water and thus a heat engine like a sterling engine.
Not much power output but nice looking !
:D
Hey Guys What do you make of this theory? http://www.youtube.com/watch?v=wvRzWYCZ2e0&mode=related&search=
Mildly funny
hehehe
hi guys.
could you guys help me out?! please.
i was thinking of building one or maybe two+ of these birds to power my small one person home. do you think is possible? i am moving out and have no choice. i will need all the electricity i can get. will be on my own now :-\
for starters like me how do i keep my batteries or maybe caps from over charging? etc.
p.s. those birds on the video didn't look too efficient because it was too windy out there.
was thinking of wrapping some coil around the bird's bottom and a magnet(s) on the ground (or the other way around) where the bird swings back and forth close the coil producing electrical energy that feed a battery.
good idea but how do i keep my batteries/caps from over charging?
AAAHHH the drinking Bird , I had fun with this in the 70's hehehe put a round concave mirror at the bottom for a solar heater it will move faster. and for the battery charger just get a power pack off a solarcell. These keep the battery up and not over charge them , just watch the wattage output of your coil and use some diodes for the backflow of power. If your real ambisous try to make a wheel like a water wheel but put sealed contaners with the pipe running across to the next (one up / one down ) with 6 arms , this will continouesly rotate and has a lot of power.
hi thanks for the tips.
could you post a drawing of the water wheel you speak of using the drinking bird principle.
also could you explaine what you mean by using diodes for backflow or power?
side note: since i bought a toy drinking bird i have learned that all you need to do is keep its head wet and its buttom dry at all times in order to function.
couldn't we just use the bird's kenitic energy to pump water from a large water container into the bird's cup of water?
here is another idea i had.
also I've read somewhere that if you paint the bird's bottom black and the head silver it will work even better too :)
tell me what you guys think.
peace
(login to see attached picture)
instead of water it should of been something that evaporates a lot quicker and the wires are coated for liquid proof :)
also forgot to include a battery that charges up and does not overcharge :)
i would probably need some switches and timers for the liquid pump as well ;)
peace
got an even better idea :)
see attachment file.
peace
Reminds me of the system we use here in the Pacific Northwest US
...sun evaporates water into atmosphere, vapor condenses into rain, rain runs into rivers, dammed-up rivers push water through turbines driving generators, sun evaporates water...etc.
Definitely perpetual motion and free energy! Except the jerks that built the dams and generators and all the wires that get the juice to my house want to get paid! And the Calfornians and Nevadans keep trying to find ways (Enron anyone?) to steal it! Dang it!

I have a feeling that overcharging your batteries will not be a real-world problem with this approach. If, after you build it, it turns out I'm wrong...drop me a PM and I'll explain many ways to use up enough of your free energy that your batteries will be out of danger.
Or...you could sense the onset of overcharge using voltage or temperature taken at the batteries and then apply a latching brake mechanism to the duck pivot...or an electrically operated valve that dumped the water out of the drinking bucket. See! There are all kinds of solutions!
Humbugger
Humbugger could you please draw a picture so we can have a better idea.
also i like to build this right away and need off the shelf parts.
i was thinking of using one of those long neck 5 gallon bottle for the head and bottom, but i can't seem to find a nice fitting pipe. will fish tank glue work good for the sealing of the pipe? should i use different materials instead? should the pipe be plastic/metal/etc?
i also plan on using the flywheel idea, possibly a geared bicycle wheel?or something else? once i got a working bird then i can "close the loop" like the above picture by making the bird sealed.
"also I've read somewhere that if you paint the bird's bottom black and the head silver it will work even better too"
- should the head be silver or white? also heard white works better.

Not a bad idea to build bigger drinking birds.
Maybe one of you guys can offer a kit, that would really be super sales item, if it is not too expensive and it will work 24/7.
Just give it every day a bit of new water and you can charge up your batteries 24/7 all day long ! Sell something like this for 200 to 300 bucks and manyvpeople would buy this, as it also looks cool... So who is going to be the first, who is offering such a kit at this prize level ?
100-200 usd sounds reasonable as long as it produces reasonable power over time.
If it produced enough to run a 25watt lamp all the time it would prove the concept. anyone ever notice that something is really hard until one person does it then all the sudden as if an invisible barrier is broken everyone can then do it.
if you make the ceiling high enough i don't think you will be needing to add water to the system. should be self sustaining :)
peace
25 Watts constant output will not be doable with smaller
sized versions, but you can use this bike light generator
unit to charge up lead acid batteries 24/7 all day /week /year
long:
http://video.google.com/videoplay?docid=6537266223222682967
It has the advantage, that it produces nice current and voltage spikes
which charge up lead acid batteries nicely and fast.
Also it does not slow down much the drinking bird.
So it would be the perfect and cheap generator for the drinking bird !
For the evapourated water, you could design a water container reservoir,
which will put water automatically into the bird?s head water container,
if the water level would fall there.
E.G. something like a swimmer controlled valve.
If the water level falls, a valve will open and
the water from an upper reservoir can flow into the lower
bird?s head water reservoir.
Thus you only have to refill the upper water reservoir
maybe once each week with some water, so not much
maintainance needed.
The power output at charged up lead acid batteries should be
enough to at least run your laptop PC for a few hours per day
and maybe some 12 Volts LED lights.
Best regards, Stefan.

Please explain how the ceiling height would effect the water usage. I don't understand that. Sorry!
25 watts sound okay,if you play around with it, and add more generators you can get to 50 watts, just like adding multiple batterys in series,
you could make a 25 watt allways on light bulb,i would think that to be cool,you could tell scientists who think free energy is aload of bull , it, heh.
well,if you come up with something quite impressive with drinking birds i would be interested in buying it.
You could crank up the output to 100watts,see how much that would be with a bit of profit etc,
to me 100-200watts sound minimal enough for me, 25 watts for a always on lightblub,
even though i would be interested in buying a 25 watt fe drinking bird machine.
heh keep going.
because the atmosphere becomes saturated with water vapor and the bird stops. we want the vapor to stay away from the bird's bottom so it stays dry :) so rising the ceiling creates distance and vapor stays away from the bottom.

If we consider that an average man in good health, pedalling hard on a stationary bicycle equipped with a generator for half an hour produces an average power of 150W and ends up pretty well totally exhausted, I think our friend mister bird is going to have to be about 373 feet tall and weigh 952 kilograms to do a steady 25W. Just a wild guess.
see my previous reply.

Okay...that seems like it makes reasonable sense...I guess. I think if a kit were to be marketed though, most folks would want it outdoors as a kind of lawn curiosity. Who knows? People do love curiosities and things that demonstrate non-intuitive principals.
Humbugger
yeah it can be outside or anywhere really.
the cover that seals the whole bird can be transparent so you can see everything never having to add liquid.

edit - the height of the ceiling will depend on how much liquid you are using i guess, the more the liquid the higher the ceiling.
guess it also depends on the weather.
Have a look at this ferris wheel.
Maybe it is better to built it like this
or combine it with a Wally Minto wheel:
(https://overunityarchives.com/proxy.php?request=http%3A%2F%2Fwww.genuineideas.com%2FAssets%2Fannimatedassets%2Fsolarferriswheel.gif&hash=f13b326c5ac71a7aeae9b9138925e52d29b61802)
Then you have a real rotation instead of a rocking for- and backwards.
Here are some great links:
http://www.wundersamessammelsurium.de/Warmes/Liebesthermometer/
There it seems that Diethylether would be the best, but today is
mostly used the less dangerous Methylenchlorid.

Regards, Stefan.
yeah i think the bird is better because you don't need a heat source really, just natural environment temperature indifference between the head and bottom. also the things i said about liquid vapor and ceiling hight etc should make it self sustaining. ;)
that solar rocker if the lights go out the thing stops no?
peace
Well,
that drinking bird is only a heat engine
with a very low efficiency.
It uses the heat difference between the
evaporated container ( bird?s head) and
the bottom to function.
So if you have maybe a temperature difference of just 5 degrees
Celsius, if you put this into the Carnot equatation
you see, that you have a low efficiency.
But anyway, built in a bigger size you can extract from each
"rocking stroke movement"
about the energy
liquid-mass x earthaccelleration x height difference of liquid =
m x g x h.
This is done best by using small diameter tubes, so most of the liquid
is transfered into the upper container, so the transfered liquid mass
is maximized.
Now this is the energy gain per
"rocking stroke movement".
If you want to know the power you can get you have to have as many
of these events per minute as you can to maximize your
power output.
Using maybe a 1 Meter high bird will only give you roughly about 1 Watts
of contineous output power I would guess,
but maybe you can move heavier masses upwards by using a hydraulic pump
with this method or put a lead weight into the pipe, so the liquid
also moves the lead weight up....
Never give up.
A constant 1 Watts output 24/7 with only using a bit of water each day
would be great to charge up accumulators and then you could extract more power
for a few hours, if you need the power then...
These devices are also interesting,
also only operate via sunlight:

Here is a great Minto Wheel prototype:
http://www.youtube.com/watch?v=-fUlKBH1sY8 (http://www.youtube.com/watch?v=-fUlKBH1sY8)
fun to watch but a stirling proly has better output.
you can put the drinking bird inside a dark room and still will work, that should tell you something.
edit - i guess you can combine the two. the bird and stirling engine
the liquid inside the bird does not need to go all the way up to its head, so this way the head stays cool. just make the "neck" longer :)
also lets not forget to apply aerodynamics for even better results!
hehehe i can't wait to build this thing!
My wife would shoot me if I built one of these LOL LOL LOL
But I like it!! LOL
A bird brained device if I have ever seen one. ROFLMAO
