Where did I dismiss it? If anything, I was questioning viability vs the internal-combustion engine; the picture is not as rosy as many would have you believe. However, I don't see how a comparison is not warranted since that is helpful in determining whether a technology is viable from a practicality and economical standpoint.
Apparently, my questioning the viability of these technologies and/or comparing them to current technology is contrary to what you either want to hear or what you believe; hence, I am dismissing them in your eyes. Truth is, they're not commercially viable now and probably won't be for some time to come whether you like it or not.
Case in point: I've attached a spreadsheet showing the break-even point between an Elise Purist Edition and a Tesla; you'll find that the car will probably be dust before you recoup your investment in the Tesla despite the fact that they are basically the same (or at least extremely similar) cars - and that doesn't take into account the usable life of the battery or the cost to replace it. In other words, it is not now commercially viable.
Honestly, I'd love it if we could meet our energy needs using rainbows, but that would be dreaming; I'm a realist.
BTW, I wouldn't necessarily say that CNG is
much cleaner or efficient. Take a gander at these and you might revise your statement:
AskPablo: Clean Natural Gas? ( CNG, Compressed+Natural+Gas, CO2, GHG, Emissions,)
California study suggests CNG emissions more toxic than diesel systems
That last one also underscores the law of unintended consequences and the cost associated with pulling the trigger while the jury's still out.
