Read a great article recently about a project/company that wants to make solar cell electrical generating facilities out of parking lots. Parking lots are actually wasted space in terms of exposure to the sun. Why not make lots do something useful beyond holding cars for hours? And provide shelter for the cars as well! And especially with more hybrid/battery cars needing recharges while parked. The concept is called a solar grove.
Anyway, during a recent trip to downtown L.A., I saw one of these facilities as part of a bank building. Way cool! Giving a little back to balance the carbon footprint.
And it helped that this solar grove was a half block from the Disney performance hall, one of my favorite buildings. I actually got a decent pic of this building.
