1.   Large solar collectors would be deployed, probably on roving processing plants, to focus sunlight on to the baking ovens.

2.   Suppose we have a processor with a thousand-square-meter solar collector.

3.   The main difficulty will be in installing the solar collector itself.

4.   They use solar collectors and windmills for energy supply and each region aims at self-sufficiency in proteins.

5.   Would not these storms coat solar collectors and solar-cell panels with a thick layer of dust, shutting them down?

6.   The concept is essentially one of replacing expensive solar collectors and solar cells with tree leaves.

7.   The use of solar collectors which can concentrate solar radiation sufficiently to generate the high temperatures needed for the thermochemical conversion of water is also a long-term possibility.

8.   Ardent ecologists, they installed solar collectors at their home in Aptos, Calif., long before the technology was readily available.

9.   In addition to developing more efficient solar collectors, it is producing a larger water heater geared toward the American market.
