To hear fans of Tesla Motors (TSLA -1.13%) tell it, our battery-operated automotive future is inevitable. But ask experts in the auto business, and they'll tell you that battery-electric systems like the one in Tesla's Model S are just one of several technologies that could eventually replace gasoline engines in our cars of the future.
For instance, Toyota (TM -0.87%) -- the world's hybrid-car leader -- has made a big bet on fuel cells, which enable electric cars to run on hydrogen rather than batteries. Toyota is far from alone -- automakers from Ford (F -4.00%) and General Motors (GM -3.81%) to Honda (HMC -1.49%) and Hyundai(HYMTF -0.52%) are putting big bucks behind fuel-cell development as well.
As Motley Fool contributor John Rosevear explains in this video, the future of the automobile is still an open question -- but hydrogen fuel cells could end up having some major advantages over batteries, and that is driving some very big investments.
