All this seems so spectacular that you would swear you are living in a Sci Fi virtual reality game. Indeed that maybe coming forthwith also. We see many companies launching plans to build hydrogen run automobiles. Honda, Ford and even BMW yet is this really doable? Well yes it is doable, but there are issues with hydrogen storage and the fact that it leaks unless stored at very low temperatures. Why does the hydrogen fuel need to be kept at lower temps due to leakage you ask? Well, remember its Periodical Table Chart Ranking. Now these issues will disappear soon with Carbon nano-tubes technologies come about and they figure out inexpensive and safe ways of manufacturing, so we can use them for the fuel tanks to hold the hydrogen fuel in without leaking out. Otherwise a full tank of hydrogen would leak out significantly in about three-days.... http://groups.google.com/group/waterforfueld Posted by Jim Wilkins on July 2, 2008, 7:26 am Please log in for more thread options >...Why > does the hydrogen fuel need to be kept at lower temps due to leakage > you ask?

Obviously you don't understand the most fundamental question involving the "hydrogen economy" or you would have mentioned it first: Where is the massive amounts of energy required to liberate, compress, cool, and transport the hydrogen going to come from? Today, most hydrogen is made from natural gas, but there is not enough natural gas to run the whole world's transportation systems, and the process of reforming natural gas to hydrogen involves massive carbon emissions. By the way, you can put your Google group "where the sun don't shine". You are welcome here for discussion, but please take your spamming somewhere else.

Gas laws explain why it is better to store cold but it does not otherwise leak if vessel will stand pressure at normal temperatures.
