no, according to YOU. Read what I wrote Raaaid..

i think youre confusing friction with wearing off

the bird PRODUCES WORK from evaporation

if you placed the bird in a well of constant level it could be working for 100 years but i admit it will not make it forever

Temperature and humidity also effect 'dippy birds' if it's too cold or humid they either stop working or slow right down... Conversley, if you replaced the water with ethanol the bird would drink faster.

So in answer to your question "why they say a perpetum mobil its imposible what about the drinking bird?"

Because perpetual is forever and dippy birds aren't. Perpetual motion requires that no energy is taken from anywhere except the machine it's self. This is clearly not the case here. Dippy birds need an external heat source to work.

It's basic stuff. What you're basically doing here is taking a solar panel and making it worse...

yes actually a wheel conected to a solar cell is equivalent to the drinking bird

but that is also a perpetuum mobil as long as theres the sun

you seem educated what about my proposition to thicken a drinking bird a trillion times keeping its height

the pressure gradient will be equal so it should work as well

the sience world has changed the concept of perpetual motion into creation of energy which is very different

we are brainwashed in college that the best engines are by burning fuel and anything better its imposible

even talking of cold fusion makes you look like a crackpot :(

Hardly original is it?

The idea of perpetual is forever, the sun isn't forever. You can't call anything that relies on an exhaustable source, no matter how big, perpetual.

Don't think a giant dippy bird is viable, massivley inefficient and financial suicide.
At the end of the day the bird is a heat engine, and a pretty rubbish one at that.

I'm not confusing anything. Friction causes wearing off.
There's a dispersion of energy,air friction, movement wear..

Stern, me old pal. Long time eh?

Question: Why the bloody hell do you waste your precious time with this?

Kindest regards and all that!

:grin:

I have observed those drinking birds work better with heavy water.

Well the airshow season is almost over and I got back here hoping for some good news,but the only updates are Raaaid's usual rambling..

I admit it,it was a weakness of the moment..
