BMW is manufacturing the first series of hydrogen fueled cars. They're not as green as they seem. For a start, they're incredibly thirsty -- and they will put more strain on the environment than a heavy diesel truck.
There's a new method for fueling cars. Instead of the usual dispenser nozzle, a plastic hose about the size of a sewage pipe is attached to the vehicle. An automatic clasp closes automatically around the tank opening.
The airtight hose system was developed by Germany's Linde conglomerate and has already been installed at several German gas stations. It's designed to allow the average person to fill his or her car with liquid hydrogen in just eight minutes. Berlin is one of the few places that already disposes of such a filling station.
