Solar Tower: Madrid, Spain

Weepowopo
The video explains it.

But I want to know why I never hear this concept brought up when people talk about the many possible sources of safe, renewable, and envriornmently friendly energy?

The video does not say when the Tower was built though I suspect it has been there for about a decade.

You hear how Solar Panels can only work during the day and that Wind Mills can only work when it's windy.
So why don't you hear about a renewable energy technology that can work a day long?
