Coal won't go away... it's use will increase worldwide. Gasification may reduce some environmental impact, though there's still no such thing as "clean" coal. And though most surveys depict a decline in nuclear, it's only as a percentage of total electrical output.
Don't shout. Possibly, if fuel cell tech can be made cheaply but there's still that pesky issue of hydrogen sourcing.
No, I don't. It's styling may merit it's current impact, but it's neither iconic or futuristic. Pokey asked "What contemporary car looks like our current view of the future?" I submit that only a few do... and of those, the technology is possibly the future as well.
You mentioned earlier your belief of our obsession with appearance over function. That's not futurism, that's styling.
Aside from an odd thing to idolize, this particular example of potential influence is limited. Perhaps I took pokey's post further than anticipated, but there's a big difference between futuristic looking cars and what technologies will make any styling predictions we might imagine irrelevant.
