Tesla reveals Supercharger network it says will cover the US in two years; Model S fills up for free, always

Video streaming by Ustream  CEO Elon Musk has finally taken the wraps off of its Superchargers which it has already set up at six locations in California, pictured in the map after the break. The company plans installations on "high traffic corridors across the US" over the next year, with units heading to Europe and Asia in the second half of 2013. According to Musk, the solar powered systems will put more power back into the grid than the cars use while driving. Oh, and for you Model Sowners? You will always be able to charge at any of the stations for free. According to Musk, the economies of scale developed while building the Model S have helped it get costs down on the chargers, although he did not offer specifics.During the event we also saw video of drivers charging their vehicles at stations today that Tesla apparently constructed in secret. They're using solar technology from (also owned by Musk) SolarCity, and can charge a Model S with 100 kilowatts good for three hours of driving at 60mph in about 30 minutes. Currently pushing 90kW, they could go as high as 120 in the future for even faster charging. Check the press release embedded after the break or Tesla's website for more details.
