For those of you who think that the BMW Hydrogen 7 is a new idea, someone has dredged up a video of a similar car from 1978 being showed off by Jack Nicholson.
The "news" report seems laughable now, but it's a good lesson for a world that see,s to think "breakthroughs" happen every day. Feeding hydrogen into an internal combustion engine is and old idea and, it turned out, a bad idea. And while almost all car companies (aside from BMW) are focusing on much more efficient hydrogen fuel cell cars, decades of development still haven't brought us a mass-market car.
We're closer than ever, of course, with the Honda FXC Clarity and the Hydrogen Chevy Equinox both on the road in California. But Hydrogen cars might need decades of development before they can operate coast to coast. And, by that time, I hope we've come up with another, better solution.

I also agree that hydrogen is an intermediate step (at best) down the alternative-energy path.

watch who killed the electric car GREAT FILM just makes you sick to see some one pretty much run a small child over for money

Considering fuel cell best efficiency of 35%, the rest heat losses, well, BMW experimental reciprocating H2 engine achieve a whopping 50% efficiency. When one study hydrogen characteristics, its very wide ignition range make it quite possible by allowing very very lean mixture. So please, forget about the fuel cell, they are only viable in Space, because hydrogen is free over there!
Just drove the BMW 7 hydrogen last week. Drove like a normal 400 hp car. One draw back is that hydrogen is kept liquid by an evaporative cycle using… you guess it, hydrogen. This means that the tank will empty itself over time (week) in order to stay cold. And the evaporated hydrogen is “burned” expelling water AND heat. Talk about a waste of energy… by the way, that would be the same regardless of the end user is a fuel cell or reciprocating engine.
