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 ?

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.

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:

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.

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

what do you guys think?

Please explain how the ceiling height would effect the water usage.  I don't understand that.  Sorry!

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.



peace

see my previous reply.

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.
