There is still a turbine. But its built in the base. The shape of the thing creates low pressure and pulls air up through the base.

Here is another design which pulls air through it, with a turbine in a tube. https://ip.sandia.gov/images/tech/2.png

Or how they can connect multiple air ducts to a single turbine https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcTV9wMkd5CFzHrGmrxKyoD2baWr-IxTcRbecQ&usqp=CAU

There are no "external" moving parts is what they mean. Like a regular turbine spinning huge blades.

If they find a way to generate energy by just blowing wind along a few copper coils, let me know.
