Dan Adams commented on Jon Kyl’s correct statement that water is required to use the sun to generate electricity with a misstatement.
Dan said that Jon Kyl said, “excessive amounts of water [is] required for present production of electricity through solar cells” (emphasis added.) This is incorrect.
While it is true that electrical generation using solar does require water (because the sun’s energy is used to boil water so the steam can be used to turn the turbines) it is not true that solar cells require water.
A solar “cell” is photovoltaic. It changes the solar energy directly into electricity. It requires NO water.
These are two different solar technologies. Dan’s letter has only confused the issue.

I agree with Dan that we need to get our information straight.
