In the movie Back to the Future, Michael J. Fox driving a car that can fly and time travel. But probably the coolest thing about Marty McFly's car of the future is also running in the trash. Imagine just rummaging through your trash to get everything you need to fuel their car. For most Americans who are spending a fortune at the pump, this sounds too good to be true.
