The first electric car powered by the sun was a 1912 Baker electric. It was converted to solar power in 1960 by Dr. Charles Alexander Escoffery. Before the invention of the self starter, electric cars were more popular than gasoline powered cars.
Escoffery’s invention used 26 square feet of solar panels mounted on the flat roof of the Baker. It could go 20 miles per hour for up to 60 minutes when fully charged. Just imagine what it could do with modern solar panels and lithium ion battery!
