Comments on: BMW 7 series runs on cold, cold hydrogen

BMW presents its Hydrogen7 car at the Los Angeles Auto Show.

Finally, Tech We Need for a Zero Emissions Vehicle

Except for the fact that we have electric car that would cost in consumer range,
and this is most likely near 1 million dollars like most other hydrogen.

Thanks for reporting,

I hope they paid you to shill that hard for them

Most of the assertions you make about the revolutionary discovery by BMW in such a short time is BS. All they did was build the first ICE that could run on gas AND hydrogen. Everything else has been done before.

This $100k+ car does not approach a true marketable car. They will release a few for lease around extremely expensive refueling stations...wow how revolutionary. Honda has had hydrogen fuel cell cars in limited public hands for over a year. GM is rolling out the largest hydrogen test fleet to both the public and military at this time.

I hope someone paid you to post YOUR thoughts

"All" they did was build the first ICE that could run on gas and hydrogen.

ALL?

Funny then that Honda or GM couldn't come up with that.

LH2 storage

Gee, whiz- a giant thermos bottle. Clever engineers! Nothing new, though-
cryogenic liquids have been stored this way from time immemorial. Of course,
some heat gets in, and physics says therefore some hydrogen must vaporize and
therefore be (a) let out, or (b) burned in the engine, or (hopefully not!) (c),
explode the tank. After some weeks, all the fuel will be gone if it isn't used.
Applies to the whole storage chain from the time the LH2 is made until it is
consumed. Or, it could be refrigerated, but that will cost energy too. Lose either
the hydrogen, or something like the amount of energy it would have produced.
Cryogenic fuels all have this problem.

Brrrrrrrr!

Cathy slowly pulled away from the corner. The light had turned green and she was relieved to be moving again. She was late to meet her husband for dinner.

Suddenly, a BMW 7 Series flashed into her peripheral vision as it screamed down the hill, towards her. As it flashed beneath the red light and rushed towards her Volvo the man driving the car behind her looked up from the keypad of his cell phone and yanked his steering wheel to the left to avoid the Volvo screeching to a stop.

As Cathy stepped from the wreckage of her vehicle, she breathed a sigh of relief that she had let her husband talk her into buying a Volvo. It was a safer car. She was living proof.

Stumbling towards the mangled wreckage of the big BMW that had been t-boned by the car behind her, she felt a sharp pain in her right foot that was immediately replaced by a complete lack of feeling. Falling forward as her flash frozen foot shattered from her own weight she noticed the smoke-like vapor rising from the small river of -325 degree Hydrogen running away from the ruptured thermos-tank of the beamer. It was coming down the slope directly towards her.

Falling forward into the strange liquid, her last thoughts were "But I was driving a Volvo".

... get the point?

Problem with scenario

Hydrogen, even liquid hydrogen at -325 degrees, turns into gas and floats away quicker than it can pool up on the ground. The main safety advantage of hydrogen over gasoline is that gas will pool up, absorb into materials, and catch fire. Hydrogen dissipates very rapidly, often sooner than it can catch fire.

Take a bomb for a ride.

BMW does it again!

A new approach to Hydrogen-powered cars, and it's available now. Still, where would you find a station that fills up on hydrogen?

Germans and Japanese are really the best !!

At Engineering.
Would like to add the italians as well.

Look all developments are coming either from Germany or Japan
Best Diesel, Best Hybrid, Full Cell etc...

Americans no longer have time for their engineering practices they are listening to to much music on their IPOD.

Even their CART race there is no real innovation, they just put methanol and they have better engines compared to what it is done in Formula One it is Day and Night.

This sure is a beautiful car :D!!
I've got the official pictures here : http://www.carchannel.be/nl/artikel/bmw/avant-premi%C3%A8re-de-nieuwe-bmw-7-reeks-innoveert , really marvelous hah :D!
