Some are focused slightly; some are not depending on the provider. If you have UPVC doors and UPVC Windows in your apartment or house you save. I think these are focused a little bit, these are not – they’re two different systems. They focus the energy up onto the receiver that’s fixed. The thing that tracks are the mirrors at the bottom.
The thing doesn’t rotate. The mirrors at the bottom simply track the sun and reflect it to the receiver. There have been two small, what we refer as integrated solar combined cycle-type plants, been done with this one small in Australia.
There’s another one called Nova-Tech in Spain where they’re doing some work.The advantage to this is it approximates a parabolic trough. It’s not truly optically a parabolic trough. There are some losses associated with this approach relative to a parabolic trough approach. The potential advantages are that it gets all of the mirrors down out of the high winds when the wind blows.
