Windmills are not designed to covert kinetic energy into heat, but into electrical energy. They do convert some of the KE into heat, which is considered an inefficiency.Buckleymanor said:So what you are saying is a tree blowing in the wind which has evolved converts kinetic energy into heat as efficiently as a wind generator which has been designed whith that in purpose to do so.
But using your inverted idea of "efficiency", a tree is far more "efficient" in converting KE into heat, because it converts all of the KE it takes from the wind into heat, not just some of it like a windmill.
Buckleymanor said:The point remains that they do not do that as efficeintly as a turbine which was why this was not mentioned.
Please define precisely what you mean by "efficiency" here. And explain how it is relevant to the topic, which is reducing the Earth's rotational KE to generate usable power with an Earth bound device.
