Syncro,
I actually agree with you, for the most part. Among the different alternatives to oil, my opinion, for what it's worth, is that electric is probably the best (or least bad) one for the way most people drive. As the owner of five older cars, one of which always seems to need some kind of maintenance, the thought of not having to worry about oil, a cooling system, a fuel system, sensors, catalytic converters, leaking seals, etc., is mighty appealing.
But I don't think electric cars are anywhere near ready for prime time on anything resembling a large scale. Electrics have a few obvious and very challenging drawbacks:
1. Range
2. Charge-up time
3. Cost
These three problems are highly inter-related: Range wouldn't be such a big deal if the charge-up time wasn't an overnight affair, and given that most people drive less than, say, 30 miles each way to work, electrics would make ideal commute-only cars for a lot of people, but their cost makes them unattractive as single-purpose cars. I think most people figure that a Honda Fit, which gets an average of 30+ mpg and can be driven anywhere, anytime, for $17K makes a heckuva lot more sense than a Nissan Leaf for $30K+.
The other big drawback is battery technology. I subscribe to Design News magazine at work, which is a very pro-electric car publication, but they just did a review of the Nissan Leaf and the Chevy Volt which stated that in extreme cold temperatures, the Leaf's range drops to a pitiful 19 miles, and that even in mild weather, customes are only averaging about 65 miles. And the Volt's real-word mileage is much lower than claimed, too. So, I wouldnt invest in electric car company stock anytime soon.
I think battery technology needs to improve pretty dramatically before we'll start seeing electrics begin to displace gas and diesel. Maybe the technology being developed at MIT which you cite will show promise, but it's typically a ten-year cycle between lab proof-of-concept and real-world application. But I have heard that good progress is being made on lithium ion batteries as well, so maybe in a few years, electrics will begin to be competitive. But of course, conventional IC engines will continue to improve in the same timeframe, so it's a moving target, I'm afraid.
So, to be a candidate for an electric car, it helps if you:
A. Are pretty well-to-do
B. Live in California, Arizona, Florida, or parts of Texas
C. Drive under about 80 miles a day, and have another vehicle you can take on longer trips
It's a pretty limited demographic, but it's a start. I guess I'd summarize by saying that all the alternatives to gas and diesel suck, but electrics probably suck the least.
I do completely agree with your assessment of nuclear power. Everybody was freaked out by Fukoshima, with good reason, but you have to realize that that plant took a hit from the absolute worst-case scenario - a magnitude 9 quake (which means that at the epicenter, the lateral movement of the earth was approximately 1000 meters, or 10 football fields!), followed by a tsunami, and yet not a single person died. Compared to the number of people that die each year in the coal mining industry, I'd say nuclear has gotten an unjustifiably bad rap lately.
Oh, before I forget, another big drawback of ethanol, regardless of how it's produced, which we briefly touched on earlier, is the fact that it can't be transported in pipes because it's so hydroscopic. If we converted completely from gasoline/diesel to ethanol, all that fuel would have to be transported from the ethanol plant to the service stations by truck. The total miles driven per year in the US is 2.5 trillion (with a "T"). Assuming the average car gets 20 mpg, that's 125 billion gallons of gasoline. But ethanol has 33% less heat content than gasoline, so it would require 166 billion gallons of ethanol to replace gasoline. An average tanker truck has a capacity of 7500 gallons, so that's 22 million additional trucks on the road carrying very heavy loads sometimes very long distances on our already crumbling interstates. And if we want to produce the ethanol from garbage or waste agricultural material, that's an additional who-knows-how-many millions of truck-miles. If you're a believer in man-made global warming, think of all the additional CO2 emissions from all this transportation. Not saying this by itself is a show-stopper for ethanol, but it's another nail in its coffin, imho.
