In 1970, air conditioning was the exception rather then the norm in New York State. Now it's rare to find a motor vehicle or indoor space that isn't chilled all summer long. That said, it looks like for the next two weeks it will be relatively cool for summertime in Albany-area.
Solar power makes a lot of sense on roof tops -- it helps shade and cool buildings, and puts the solar cells in a better angle for unobstructed sun. Solar roadways, in contrast, have all the disadvantages.
Solar panels are very sensitive to shade and angle to the sun -- in my personal experience with my solar panel. To say nothing of heat. I can't understand why anybody would have proposed the solar roadway idea in the first place. It just doesn't make much sense.
