content: Yeah, I'm with you on this one. Coal powered cars went out of fashion pretty quick back in the Victorian era. But, the upshot on this is that a solar setup on your roof and a battery bank isn't really expensive compared to the cost of fuel. That way, you know your car isn't powered by coal and you'll end up saving tons of money on gas or diesel. My setup was pretty expensive if you are just looking at the price tag because I'm basically paying for 30 years of fuel / electricity upfront. But, if you factor in the lifetime of the system into its cost per month, it's actually really really cheap. I'm saving enough money that it would be like expecting the power and gas station to give me a new Honda Civic in exchange for 30 years of loyalty. They aren't offering, so I'm not buying.
