BMW Develops New Generation of Hydrogen Storage Tanks

how is it not friendly? what are the wastes for hydrogen? Waste of hydrogen is water vapors.

omg... fshizl. when's the last time you went to science class?? seriously now... hydrogen doesn't just come out naturally. You have to actually produce the hydrogen aka make big factories to do so AKA polluting the environment to MAKE the hydrogen which we will use in our cars. When its used in our cars they do not emit any emmissions as you said yourself, but to MAKE it, the process emits pollution.

isn't that why their spending research money on CONTAINING the hydrogen?? aka what this article is all about... "new generation of hydrogen storage tanks".. lol

and if its so useless, why don't you come up with something better lol... like seriously it emits water. unless you make something that emits "air" please don't diss these USEFULL ideas lol

uhm. Regular gasoline engines emit water and air... If run under perfect combustion they can even burn off all those nasty greenhouse gases. Unfortunately, that extra cleaning results in a decrease of efficiency so your gonna get worse mileage. Something better... how bout hydraulic launch assist... it emits nothing, requires no harmful batteries or any other chemicals, is cheap, easy to fix and build.

i didn't know gasoline engines emit water and air.... lol i thought they emit CO2?? :P

of course they release water and air, but for air, there are many different components to it. It's about 78% nitrogen, 20% oxygen and 2% misc gases. The nitrogen can react with oxygen to produce NO one of the green house gases. But this usually happens when the combustion isn't fully executed. The water comes from the chemical brake down of the fuel. After all, for the most part fuel is a big mixture of hydrogen oxygen and carbon molecules. All of the hydrogen molecules bond to the oxygen to create water. When it leaves the cylinder its super heated vapor water. But often times by the time it reaches your exhaust tip it has cooled enough to drip out of your exhaust pipe. Especially when it is cold out side. As to CO2, you have to remember that everything emit's CO2, you me. Even plants at night time emit CO2. The part that environmentalists are worried about is the CO and NO. These are nasty gases that are hard to get rid of. And they mostly occur when an engine is not operating under ideal conditions. That being said, reducing carbon content is not really an accurate measurement in the eco battle. If you really wanted to reduce carbon output, you would shoot yourself in the head. No more waste/CO2/or other side products from living.

Here we go again !!!!! :

Not really, but it has the exact same side intakes, I'll give you that.

hahaha... it is an inefficient energy storage system (comparable to battery powered cars... but only more dangerous). If we were to convert all of our cars to it we would still be burning just as much petroleum. Also, we have lots of oil in north America. Just look at the Alberta oil sands. The reason why we aren't focusing much on it is because people find it more ethical to kill off the "Sheikhs of Abu Dhabi" then it is to actually pay for your oil.

Unfortunately due to the laws of thermodynamics, you can only ever get out the energy you put into hydrogen... and then you have to fight the problem of not being in a real world and all of the inefficiencies found in all of the chemical-mechanical-electrical-chemical energy transfers. A middle chemical step would only result in toxic wastes and or the consumption of some other resource (probably a petroleum byproduct).
