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

You have missed the point totally, the description of a perpetual motion device is "motion that continues indefinitely without any external source of energy" your bird has an external source.

The science world hasn't changed anything, without creation of energy how could you have perpetual motion?
