Is it as green as it first appears? http://www.bbc.co.uk/news/business-10836132 |

I think its the ineffiency of making hydrogen that the big problem...if the hydrogen production is powered by fossel fuels then its less green than burning the original fossel fuel directly in a vehicles engine. If the process is done by using renewable energy such as from wind turbines then it becomes ridicoulsly expensive and would make the hydrogen highly uncompetitively priced for decades to come. Looks more to me like Green spin than a realistic possibilty....It appears up front to be Environmentally friendly at point of use...yet behind it all it leaves a bigger carbon footprint than a Himalayan yeti burning coal in its slippers.. |

Only if it uses leaves a smaller carbon footprint than the diesel engine that its meant to replace...sadly it seems that it doesnt as it creates a bigger carbon footprint in the making of hydrogen than it would take to allow it to cover a similar milage in a diesel cab. All it actually does is to run cleanly on the city streets thus leaving its Co2 emissions at the Hydrogen production plant....the Polar bears wont be impressed. Im not a believer in man made climate change so its emissions dont bother me....what does bother me is that we are over reliant on oil based fuels, the quicker we can find a reasonably priced alternative the better....its not good to be dependant on those half baked and volatile oil producing giants..

The research url'd below was carried out by some Polar bears as part of their PhD in Science thesis at "Freezmabawsoff University" in the Russian Arctic region.. http://www.commondreams.org/views05/0619-23.htm |
