Mass. - Today's cars are running on empty.
Oil supplies are good for only a few more decades.
And fossil fuels are also a major source of pollution. If we want to keep the rubber meeting the road, we'll need a miracle, a car that practically runs on water. Actually that dream is becoming a reality. Ravi Datta, chemical engineering professor and department head at Worcester Polytechnic Institute, is researching a mode of transportation that emits essentially no noxious fumes into the atmosphere. It depends on a renewable fuel that can potentially last forever.
