If you go to www.permaculture.com, you may read that KQED produced a documentary on making alcohol for gasoline, but then buried/killed it in 1983 when big buck contributor and no friend of the public interest Chevron objected. So what if pbs stations are better than most commercial stations. If this pbs station violated our public trust so basically and maybe allowed us to be the suckers for two Gulf wars. Instead , we could be driving lots of sugar-based alcohol engine cars, vegetable oil that is cleaner than petroleum diesel oil turbo charged engine cars, and lots electric cars that the feds pulled off the market for no good reason.
