Dave Buchko Explains the Hydrogen 7 BMW

This car burns liquid hydrogen in an internal-combustion engine. It is not a fuel cell, but it still has ultra-clean exhaust. Some 40 of them are on U.S. roads. The hydrogen is in a liquid state at -423 degrees Fahrenheit!

@simplemind111 Because they know that people would be able to make their own hydrogen at home and the "monetary system" as we know it would collapse. A "Resource Based Economy" is what we need if we want hydrogen cars and green energy like "Enhanced Geothermal System" to produce the electricity to make the hydrogen.

@m19921992 Dave, I would love to see hydrogen powered cars go mainstream too. But there is a reason that you and the other auto manufacturers have been going at it for the past 25 years like you said, and there is still no one actually selling them. The Honda FX Clarity is an awesome car too, but why haven't they made more than 20 or so of them? BMW seems to understand this too, look at the vehicles project i is developing, they are all BEV's and plug in hybrids & plain hybrids. No hydrogen.

@simplemind111 well even if there were few stations I wouldn't mind being an early adopter of a hydrogen car. If people don't mind not having many places to fill up for awhile this could really take off, most major city's already has at least one station at the moment so its not too unrealistic. Plus, car enthusiasts like myself will be very happy to keep our combustion engines. I wonder how long before Hydrogen conversion kits are available to convert older cars to hydrogen?

[simplemind111]

We all know that it is not too difficult to make the cars. The problem is making and distributing the fuel. That's the 800lb gorilla in the room and the reason hydrogen vehicles are decades, if ever from becoming a viable fuel for personal transportation. Getting the fuel infrastructure in place, or as Dave say's "that last step" is a nearly insurmountable task due to the cost. It will cost every gas station that converts about $1,000,000 to do so! Battery electric cars are the way to go for now

@0Sebek0 The critic temperature changes according to pressure. In regular pressure, yeah, it takes -241 C to turn hydrogen into liquid. But if you put it in a high pressure tank, it turns liquid at room temperature.

[sensaybob]

yeah, they store it as a liquid because if they stored it as a gas it would force the car to be ridiculously large. and the issue is that hydrogen isnt explosive as a liquid, but if something were to go wrong and it lost pressure and turned to gas, it does become explosive (like gasoline, it has to be vaporized)

a lot of people keep saying its too unsafe because its so volatile, but if you use a tank like a fire fighter's tank or a scuba tank, theres no problem. thick steel.

[HHOhybridBuilder]

I like the idea of hydrogen as fuel.That liquid hydrogen in the tank, is it safe? Does hydrogen in a liquid form explosive? This is the only thing I'm afraid of about hydrogen fuelled cars.

wow I like the way he says.."the ultimate driving machine" makes me wanna have one :P

[NancyAliceCullen]

Im best friends w/ hisdaughter Emma! The hydrogen car ia awesome (I got to ride in it)!

It has a huge tank in the back to store hydrogen.

wow
