I hope so, but I bet there are number of problems we are not hearing about. For instance, how is energy generated to produce hydrogen? Coal fired plants? Natural gas? If natural gas, would we be better off economically and environmentally using natural gas cars? What about the materials in the fuel cell? Are they more hazardous than present cars? I am sure we will find a better answer to the internal combustion engine, but when it is PBS pushing the idea I become skeptical.
