The Society for Sustainable Mobility, formerly known as the Open Source Green Vehicle project, is one of the official teams registered for the Automotive X-Prize competition.
The X-Prize Foundation got a lot of press in 2004 when it awarded $10 million to the first private team that built and launched a vehicle carrying three people 100 km above the earth. This year, the foundation has been working to get the funding for the Automotive X-Prize: another $10 million to the team that can build a marketable 100 MPG vehicle. Will open source win the prize?
