As a Computer Engineer who loves to program in open source languages and use open source software, this news from Tesla sounds terrific! They are in effect open sourcing the technology they are using to make the Tesla EVs. Here is the link to the press release: http://www.teslamotors.com/blog/all-our-patent-are-belong-you
That means that other people can build upon their technology base, just like programmers can build apps for Android on your cellphone or tablet. We are truly entering a new stage in the new information revolution! Moving from the industrial/factory model to an emerging open source/creative model. If you want to find out more about open source, it is a fascinating concept that has altered the world of computer technology for a long time – now moving into EVs.
We will have to wait and see what the other EV companies do – or maybe it will be up to a new crowd to take EVs to a new level. In any effect, it is exciting!
