“From the wind!”

Absolutely not! It’s there in black and white. It comes from a fan compressing air and shooting it out. That’s what’s known as a turbine. What powers that turbine?

And you didn’t answer my other questions.

But I didn’t expect you to.

Me: ““From the wind!”

“Absolutely not! It’s there in black and white. It comes from a fan compressing air and shooting it out. That’s what’s known as a turbine. What powers that turbine?”

You do not understand how this operates. The turbine uses only a small amount of power which creates a pressure differential resulting in a large energy gain for propulsion from wind energy,

I directed you to their website for the details.

You got it all wrong.   It is not a turbine.   It goes all the way back to the Bernoulli family who investigated hydrodynamics and the subsequent Magnus effect named after the German physicist who investigated it.

The Magnus Effect is a feature of airflow around a spinning body that is also moving relative to the airstream (or that has air flowing over it). The spinning flow combines with the one-directional flow to produce a net sideways force that, unless balanced out somehow, will push the body to the side.

See "WhoisAlanGreenspan?" fantastic video primer on the subject.
