The world's politicians are currently huddled in Paris arguing over how much effort they're prepared to make to stop the seas from boiling. As such, France has decided to throw down a well-tailored gauntlet to its partners by announcing a competition to build an electric car that costs under $7,000. The country's ecology minister, Ségoléne Royal (pictured), revealed that she'll launch a project that'll encourage private companies to build an environmentally-friendly ride for the population. How will they be able to keep the costs that low, you ask? By ditching the built-in battery in favor of a country-wide network of stations that'll let people swap cells during their journeys.
