Progress On Electric Cars
Mike sends along a couple of items of interest to those anxiously awaiting the era of production electric vehicles. First, there's the upcoming Aero EV, which Shelby Supercars claims will charge in just 10 minutes and will be able to produce over 1,000 horsepower, powering the vehicle from 0-60 mph in less than 2.5 seconds. Then there's the announcement by Aptera of the first pre-production model of the Aptera 2e, which will have a top speed of 90 mph and go around 100 miles on a charge. This EV also features a strong and aerodynamic body, a lithium-based battery, front-wheel drive, and an improved door design. Release is planned by October of 2009.
What, no love for the Big 3? Lemme see here. We've got the range-extended Town & Country EV from Chrysler that will do 40 miles on a single charge, plus another 360 miles using a mixed gasoline-electric propulsion. They're also working on Dodge and Jeep vehicles with similar designs.
Ford used to have the market in a bag with their Ford Ranger EV pickup. Of course, they discontinued it in 2002. Now they're playing catch-up with the rest of the market. They are promising an electric vehicle by 2011, so there should be plenty of competition in late 2010/early 2011.
Speaking of competition, what discussion is complete without mentioning the Chevy Volt? Still the gold standard for the emerging industry, it will be anyone's guess if it lives up to the hype.
I rather like the look of this car, but I am concerned by a couple of issues. First up is the single back wheel. Won't that make the vehicle a rollover hazard? I presume the front wheels are extended to help mitigate this issue, but one good blowout looks like it could send that sucker fishtailing right into roll. (And for that matter, how servicable is that tire?)
My second issue is the power-train. Generally you want as much weight sprung as possible, and electric motors are heavy. Aptera seems to understand that as it appears there is an axel linkage on the front wheels. Presumably this is how power is transmitted. Is having that axel exposed going to cause any safety and reliability issues? I'm just imagining something flying off the road and getting wrapped around the the axel. Or in an accident, a pedestrian getting an appendage caught in there.
Or is this a rear-wheel drive vehicle? In which case, is that axel really necessary? Could'nt the steering be accomplished by swiveling independent pods rather than linking them?
Just my 0.005 cents worth after accounting for inflation. :-P
P.S. The Shelby looks pretty darn sweet! I'd never spend money to purchase a vehicle like that*, but I wouldn't mind taking her for a spin.

Coal has killed FAR more than is attributed to it. Right now, nearly all the deaths attributed to coal is based on coal mine deaths, which IS much greater than nuclear power deaths (even when including all the uranium mining for weapons). But what is not added in there is the mercury poisoning that we get. Most of the mercury in our water is from coal. Likewise, much of our acid rains, etc are from coal. In a nutshell, Coal is far far worse than nukes.
I prefer the "u" in honour as it seems to be missing these days.
According to a DOE study conducted at PNL, switching to EVs is a net win even on our current grid. The main reason is that power plants are a lot more efficient than gasoline-powered cars at turning fuel into energy, while transmission and charging are very efficient. Also, EVs, which mainly charge at night, reduce the need for spinning standby, allow plants to operate more efficiently at night, and so on. The net result is that you could switch 84% of our cars over on our existing grid and you'd cut CO2 emissions by a third, increase PM somewhat, NOx would drop slightly, SOx would stay the same, and CO and VOCs would be nearly eliminated. The pollutants that would be emitted would be emitted on average much further from people's lungs and so affect them less.

The big problem with electric cars is energy storage. Lithium batteries are too expensive, take too long to charge, don't have a high enough energy density, and don't last long enough. If the current work on ultracapacitors pans out (and that's a BIG if) electric cars will become a lot more practical for the mass market.
There are certainly issues with current electric cars, but only by having them in the market place in some form will there be any incentive to improve them. Lithium is expensive, but it will come done like anything else.
My concern will electric vehicles is how they will pan out in cold climates, like Scandinavia or Canada. From my experience batteries perform badly in the cold, with apparent charge dropping off until the battery is warmed up. For me this is where the real test of the technology will happen.
