Good article, stupid companies trying fuel cells. We'll show them how to do NOx free hydrogen jets with onboard oxygen. This is precisely a good program for open source, where small ($1B) SAB peoprietary teams can't pull it off because they are not efficient or effective. At 10x efficiency via open, this is a perfect student project, and we can dedicate a full 240 Campus to it next year. First housing, second energy, third cars, fourth jets.
