General Motors ( GM) is reinventing the automobile as we know it by making one that runs on hydrogen. It's sounding like a nearly a done deal -- the fuel-cell technology, the car that can turn and essentially brake by itself, emission of nothing more toxic than water vapor. Wait a minute. The Business Press Maven begs your pardon. Right when I was about to invest my entire three-figure family fortune on the hydrogen car concept being heavily pushed by General Motors and getting overly kind publicity in our nation's media, I realized that hydrogen was what the company was putting out there for public (relations) consumption a couple of years ago. This morning it's the all-electric car. And it just this minute occurred to me: Why don't many of today's excited articles on the potential of the all-electric car mention the apparent disappearance of the hydrogen-powered car? The Business Press Maven must be fair. Look around at coverage of this all-electric car and you'll see that some media outlets, even without offering the proper perspective on hydrogen, are seeing the future of all-electric in a limited way. Just how limited is it? The battery needed to power it, for example, has yet to be invented. But rather than reflecting on GM's public relations push and apparent withdrawal from its hydrogen efforts, too many in the business media are repeating it.
