You really can't use initial price as an indicator of a product's potential viability. Final price, on the other hand, is a great indicator. If the final price has no chance of ever being low, then we might as well give up on the idea right now. Tesla Motors's accomplishments are really interesting. They've got everything a gasoline car would have, aside from price. http://en.wikipedia.org/wiki/Tesla_Motors Now here's the real question: If li-ion tech batteries enable 300 mile range for a family sedan right now, ...... what are the odds that maybe another battery tech might exceed that limit even? If it does, wouldn't that mean that electric had actually reached the point of being superior to gasoline, rather than just matching it? I think the reason people object to the use of the term "pipe dream" is because most pipe dreams have no potential to be fullfilled regardless of what time frame you put them in. If you mean that people are expecting this transition to be easier than it's going to be, then I'd say "pipe dream" is a perfectly accurate term. Moving to electric isn't going to happen without a deliberate and concerted effort.
