So where is this technology, today? Is it somewhere in the soup of energy ideas that are only 1/3rd developed and nobody wants to drop seed money on them (because we are in a tight economy)? So, instead of actually developing the technology, we will publish intricate details about it in public spaces and stand around to let the 3rd world read and develop these paradigm shifting developments. Any chance for an economic recovery clearly needs a risk taker for such shifts; keeping the money to yourself means you will sink with the ship, but you take no chance of making the needed life raft. Good show, old chap!

It seems as though “Uncle B” overdosed on the Obama Kool-Aid. Obama and Bush are two sides of the same corrupt “Republicrat” coin. It’s time to come back to reality and lose your “Obama can do no wrong” delusion.

ther is not enough nickle and litium for long term unless sea is mine, for these types of batteries long term,

hydrogen pills inert ammonia, as compared to liquid not inert,ammonia, one a hydrogen casset can be renewed and because intert can be posted until large ammounts needed hydrogen economy, also there are many ways to extract hydrogen once platium is not needed to, , it should be easy to make, work,and to the size of conventional, tanks same distance, and there are still, more solutions, im willing to bet.

the energy input source to produce the hydrogen is where the prohibitive cost comes from, we have an abundunt renewable source for that energy. using electricity generated from solar panels (themseleves made more efficient via carbon nanotech) hydrogen can be produced via electralysis cheaply. Ideally a combanation of technologies will be required to make a hydrogen vehicle the superior product. A self contained system that utilizes an onboard store of water as a fuel source, using stored (battery) power to split and compress it to provide a constant flow of fuel to the cell which then recycles the water. Charging the generating battery can be supplemented via regentive braking, an onboard solar charger and waste heat conversion. No, it will not be 100% efficient, it does not have to be, it will extend vehicle range. A maintianed loop system.

Hydrogen production takes a lot more energy input than the energy content of the hydrogen produced. This is why electric cars are in the long term more effective then hydrogen powered ones.

Will it take 10 years to commercialize these carbon nanotube fuel cells?

I recently read where a scientist in the UK was able to get hydrogen by using sound waves on sea water. Anyone open to a sonic carburetor? Also, the hydrogen cars would not be allowed to spew water vapor unless it was in very tiny amounts. Water vapor is a greenhouse gas that is ten times worse than carbon dioxide.
