Nissan just announced it will be equipping all cars sold in the U.S. and Europe with these $50 solar powered car battery chargers. ICP manufactures a whole range of solar car battery chargers for the general public, costing from $50 to around $1,400. Right now the chargers will be used to keep the batteries nice and charged up while the cars sit on the dealership lot. But if you are a car owner with uncovered parking, this could be a great buy for you, too!
