I could buy some electric car and stick solar cells all over the roof. Plus some wiring and a charge controller. That would be about a day's work. If one day I need a car that can, say, play music for days at a festival in the summer, I'll do that. Of course, to improve the range of the car with it, it wouldn't be worth it. The expense of a whole working day would be far too expensive for that. I think solar cars are a scam. The victims are these investors with a good heart (save the planet!) but no clue at all about engineering or science.
