Amory Lovins talked about the hypercar project, a radically redesigned car that uses hydrogen fuel (producing water as its exhaust) or fuel cells. It reverses most of the principles that have guided car design from the beginning. Most exciting, he has put the design into the public domain so that no one can patent it and many can build them. ~ David Weinberger from the TED conference.
Good. Among other things it works to undermine the frigging nonsense about borders that cause us to believe technology and entertainment are separate spheres that need to hold special events to talk to one another. The public domain is what never somehow manages to be present at any of these occasions. (Fucking over the oil barons is gravy.)
