But my point simply was that purely electric technologies cannot satisfy all needs (yet?) and that the range capabilities of electric vehicles is not on part with fossil-fuel vehicles (which is what was seemingly claimed by the parent post). And yes, this might mean that fossil-fuel vehicles don't disappear entirely, but simply play a smaller role in our future society.
Now onto your post: Writing off something as DOA because of current technologies is not a good argument at all. People made similar arguments about electric cars just a few years back (as shown in 'Who Killed the Electric Car'). A long time ago, no one ever thought computing would be cheap enough to be inside consumers' homes. There is always the possibility of a break-through technology, of a reduction in cost, increase in efficiency, etc.
The quote above cherry-picks some statements in 2008 regarding GM and Toyota's views at the time on fuel-cell vehicles. However, there is a long list of companies who have publicly talked about their investment (and upcoming production vehicles as well) in the fuel-cell space just this year (2012!). A quick search through fuel-cell news this year brought up the following: Honda, Hyundai, Mercedes-Benz aka Daimler, Audi aka VW, Toyota, GM, BMW. There are probably others as well, but that already covers the vast majority of vehicle manufacturers.
Secretary of Energy and Nobel Laureate Steven Chu reversed his view on fuel-cell cars and noted recently (mentioned towards the end of your quoted text as well) that there may be a higher feasibility for fuel-cell-based vehicles now.
There is ample proof that fuel-cells deserve more attention and research before closing the discussion. It is worth investigating this space if only to have alternatives - electric vehicles have some issues (range, cold weather performance, environmental impact of producing batteries) that perhaps other technologies could address.
Relative to battery-powered fully-electric vehicles, some advantages are: - Quick re-fueling (like with a gasoline vehicle) - No loss of range in cold weather (and seems like earlier freezing issues have been addressed) - No deterioration of a battery's performance over time
Some disadvantages: - Hydrogen economy is not here yet and may be difficult to make efficient relative to electricity delivery (http://en.wikipedia.org/wiki/Hydrogen_economy)
No, it is expensive _today_. Which is different from saying it would be expensive at scale.
As a comparison, my gasoline-hybrid can squeeze out over 500 miles on a tank at 55 miles an hour. And I never worry about being 'stranded' as I might with a fully-electric car.
Another issue I have with battery-based solutions is the potential lifespan of the batteries - they are warrantied only for 8-years. A new pack costs ~30k (pulled this unofficial figure from discussions in the Tesla forums).
Another note: while China is the world's leading emitter, they also have contributed the most to abatement of emissions according to some (example: http://www.dbcca.com/dbcca/EN/_media/Global_Policy_Tracker_2...) Let's not forget that the US did not ratify the Kyoto Protocol, while China did (http://en.wikipedia.org/wiki/List_of_parties_to_the_Kyoto_Pr...).
Another way to look at this is a simple cost-benefit analysis: is the cost (I mean more just than the monetary face value) of having a regressive tax more than the cost of potential issues that result from not addressing emissions? If so, we should do it anyways.
A Forbes article (http://www.forbes.com/sites/timworstall/2012/10/30/explainin...) explains further that the complaint from French publishers is about the portion of the search results page that shows links to those publishers' content (since that results page has ads on it). They could exclude themselves from indexing easily (and forego traffic of course).
