115-Foot 'Tulip' Harnesses Sun's Rays to Power Villages

I'v seen this on a TV programm recently here in the UK, and I have wondered why this hasn't been done in more countries?

It is much better than the thousands of unsightly wind-turbines that litter our beautiful countryside, or the wind-turbines that litter our coastal waters, and it is much, much more efficient, because the wind here in the UK doesn't blow all the time, and if it blows too hard the turbines have to be stopped, thus they only produce about 12% of the promissed electricity (efficiency)!

Combustion????

Obviously not enough info is presented. I am under the impression that you want the incoming air to be as cool as possible for better combustion, Leading to more expansion.

When I first read this article I thought they were using the "tulip" at a chimney and had a fan driven by the rising air. I know that can be done.

How is combustion here any different then running a jet engine turbine to create power? Is this supposed to be "greener"?
