What do you mean by infrastructure? There are already simple autonomous hydrogen production systems that can be installed anywhere.
as said, those systems aren't yet energy efficient enough, and, we don't
yet have surplus renewable/solar electricity to run them, either, which could, make hydrogen more competitive, for consumer use.
if you had that electricity the other advantages of hydrogen, lighter weight of the tank+fuel cell, and, probably lower carbon manufacture cost(vs battery) would come into play
R4, just this morning - motor manufacturer survey 'many' people aren't plugging in phev so they are more polluting than ice, due to the weight.
but really modern electric car for casual Mr. Smith on the street was given by Tesla.
I think we are waiting for vw, or others, to bring the technology to the masses, at a viable price, and tesla meantime are viewed, like a modern DeLorean, by the average UKer,
a pioneer, that will be overtaken, by more efficient manufactureres who will provide a peoples car.
the more familiar mobile phone processing analogy - is the computing power in a phone versus what which went to the moon. ?
but a 250w GPU is still about 100x more than a phone, PPW will get there by 2031 or thereabouts for a phone
PPW ?
phones and gpus are using the same transistor/fab technologies ~14nm, phones, if anything, being more energy efficient flops/watt,
processors in gpu's are not general purpose too ... why nvidia's buying arm ?
edit petaflops/watt ?
