"CNG for trucks is a bad idea. Trucks work well on diesel, which provides lots of energy per litre. " CNG for trucks is a great idea... trucks that work well on diesel, work even better using CNG or a mix of diesel and CNG. They burn vastly cleaner... the key benefits of which are more power per litre, and a vastly extended equipment life. Burning CNG properly will mean the truck equipment itself lasts 5 times longer. It being perfectly sensible from an engineering standpoint... still doesn't mean all of the economic aspects of fostering fleets of mixed fuel vehicles will intrinsically work themselves out, as if we had a free market, when we don't have a free market. "burning the tars and methane in a power station to generate electricity for battery powered Halo cars [by Qualcomm] would be better still. Power stations are very efficient compared with diesel vehicles because thermodynamics favours very large stationary energy conversion" Power stations are more efficient... only if you use the power at the point it is generated. They are obviously much less efficient... if you have to account for the losses that occur in transport of the power after you produce it... and the economics take a hit, too, if you have to consider the cost of re-engineering the distribution systems as a part of the total systems cost. The same sorts of issues exist in computers... with the market appearing to think there is a need both for grid connected desktops... AND battery powered mobile devices ? Only, in transport, its the batteries that will require you are more closely connected with the grid ? Smart phones are cool... but, if you're outside line of sight of "the grid" they depend on... you might as well use them as fishing weights ? The product you choose... will depend on your situation and your need. The impact on global warming ? None. The impact in economics of preserving and sustaining profitable but wasteful inefficiencies inherent in legacy systems ? Huge.
