An interesting story on Forbes.com discusses the once futuristic idea of ones home as a source of hydrogen for cars powered by the fuel. Check out this line from an executive at GM: “Quite frankly, the transportation sector, to a large extent, is held hostage to petroleum. That’s been the lone source of energy for the transportation sector for a century,” said GM Vice President Larry Burns, head of its research and development. Wow, he could be at risk of adding “former” to his title if the oil honchos get a load of this. He wasn’t done: “They’re not going to sit back and let this happen to them,” Burns said of the oil companies. “So what we’re hoping that we can do is create a good dynamic between electricity, natural gas and petroleum as sources of energy for transportation.” Very interesting.
