Not as bad photovoltaics in terms of dropping off when the sun goes away. This is very important in production of UPVC Doors and UPVC windows. They will cost for a while, maybe 30 seconds to a minute. How do you handle that? We’re working with these to look at some thermal storage approaches.
They might give them short-term thermal storage. That may be enough to make them extremely viable.I summarize what my points are on each of these technologies – the trough systems, the steam power towers, which to date, we don’t have one operating at very high efficiency because its temperature is so low.
The dish sterling systems and the molten salt power tower. Let me summarize my status. Trough systems are the most commercially mature. There’s no question about that. They were enabled by the Luz projects at SEGS back in ’85 to ’91.
