This sounds like it is modeled after the solar power plant that DOE sponsored at Daggett California....

Ahh, Daggett. That brings back memories.

I worked a Natural Gas Compressor Station project across the street (Route 66) from that facility.

The Solar Trust project reported above uses arrays of curved mirrors focussed on a central tube which contains the water/steam. It is not the "power tower" design at all. Probably a lot more efficient as it will require much less heliostatic activity to keep focussed on the medium.
