The X Prize Foundation wants to break our addiction to oil and slow the effects of climate change. They’re offering a multimillion dollar prize to the first team to create a low-emission, 100 mpg car that’s safe, affordable and ready for mass production. The contest is gaining speed internationally, with more than 30 teams from numerous countries. Mother Earth News is an official sponsor of reader Jack McCornack’s roadster entry; watch it evolve and learn how to make your own!
