The father-son company, Human Car, have invented a car even more eco-friendly than the hybrid or whatever that hydrogen fuel-cell is.
According to this article from Wired the Imagine car is something straight out of The Flintstones (click to watch the intro). Only instead of Fred and Barney pedaling, it uses arm power (along with a little battery support). So, take one part modern Stone-Age family, one part early rail car, mix in some batteries and some recumbent features and you get the Imagine!
Hopefully cruising into a college campus near you, the Imagine is so green that it doesn’t even use ethanol – it uses calories! So, it’s clean and it fights obesity (which based on the season premiere of The Office is apparently an epidemic of huge proportions).
