It seems to me that the only way this technology will become positively pervasive is if the car also has an H generating unit along with the power unit thus making it totally self contained. The car could then be used to generate home electric power when not driven, with the excess sold back to the hard wire electricity provider thus giving many drivers a profit motive to switch to cars having this new tech. Storing H in big tanks within the car is questionable, as out of the tens of millions of Ford Pintos and Chevy PU trucks made in the 70's, a few blew up due to gas tank impact explosions and created a huge public outcry. Will the same thing occur with H tanks in testing and render this new tech unsafe for cars before it even gets out of the gate? I fear it will(or should) and wonder: is there a process under research that produces H immediately before combustion thus making a holding tank unnecessary? Thanks for informed responses.
