Small Electric Car May Usher In Big Changes

An anonymous reader sends us to a profile in CNNMoney.com on a Norwegian car company that is building a compact, plug-in electric car, the Think City, that will go on sale in Europe early next year. It could hit US markets in 2009. The CEO is working with Silicon Valley VCs and with Google, Tesla Motors, PG&E, and Dean Kamen, inventor of the Segway. Plans are to sell the car only on the Web. No dealers, cheap manufacturing plants, and a battery pack that you lease, not buy — there's potential here for shaking up the auto industry the way Dell did PCs.

Carbon Free?

..carbon-free electric driving machine

I appreciate that looking forward a larger proportion of our electricity will come from sustainable and green sources, but given the current situation I can;t see how they can claim an electric car to be 'carbon free'. Admittedly the car itself emits very little carbon, but this just means that the carbon emissions are being diverted to the power generation (unless of course, the electricity is being generated using a perpetual motion machine). Also:

He points to the black steel chassis of a City standing on a nearby pallet; it's shipped preassembled from Thailand. At one station, workers attach the car's aluminum frame -- made in Denmark -- and drop in a French motor. At another station, prefabricated rust-and dent-resistant polymer-plastic body panels produced in Turkey are hung on the frame of a nearly completed car.

I'm not sure how shipping in different parts from all corners of the world necessarily helps the 'carbon-free' thing either. Basically, my thinking is that until electricity supplies are all (or at least mostly) from renewable and sustainable sources then a small electric car is no more or less environmentally friendly than say a small diesel car.

Stirling Engine

If I were to design a car these days, I would do as these guys did and use an electric motor for propulsion, and a Stirling engine for power generation. For those not in the know, Stirling engines are engines that run on heat. They can be powered by pretty much anything that generates enough heat, including but not limited to fossil fuels. Compared to conventional combustion engines, they Stirling engines are more efficient, but they take a lot of time to increase or decrease speed. That is a problem when using them for driving the wheels, but not when generating elcetricity.

Thanks to AKAImBatman for pointing me at Stirling engines; I first read about them on his blog.

Cheaper one from India

[ScorpFromHell]

did we ever discuss about the Indian electric car company Reva any time in the past? Their latest variant, Reva i, released this month costs around USD 9K (at exchange rate of INR 40 per USD).

Sure, it can only do a top speed of around 50MPH with a range of 60 Miles per charge, but I guess that's enough for city driving? I don't know, but is USD 9K too much for a small electric car that can carry two adults & two children in your place? In India, it is a viable option as a second car, for the growing numbers of nouveau rich at least.
