[Pil-pc-oceania] Zero carbon, zero waste, car-free city in the desert

[Dr Bob Rich]

It's a con. Hydrogen is not not not zero-carbon. It is a very  
inefficient storage device for electricity. CO2 will have been made  
during generating the electricity, and during using it to electrolyse  
water to form the hydrogen. Then there will be losses during  
transport and storage. H2 is such a small molecule that it can make  
its way through many apparently solid walls, never mind joints.
	The fuel cell itself is efficient enough, but as with electric  
power, the losses are before the consumer gets the energy.
