I've been following Goodwin's story for a while. He makes no "secret" of what he's doing and implies no magical knowledge. If you've got the money you can access any ideas he's come up with. No BS there.
The Mustang story would have been more believable without the wild acceleration claims and saying the idea is 60 years old. That perks up everbody's BS detectors.
The Goodwin article brings up the big chicken-and-the-egg problem of alternative fuels: people won't buy cars using alt fuels without an infrastructre in place, and the companies that would provide that infrastructure won't do it until there are cars to use it.
