Being Earth Day yesterday I got a glimpse of the series Big Ideas for Small Planet and happened to watch the segment on alternative fuels. I may have caught it late but they didn't seem to mention natural gas as one of the alternative fuel choices?
They plugged veggie oil, bio-diesel, hybrid and ethanol or did I just miss the natural gas part? Quite dissappointing if the producers elected not to include natural gas.
Interesting series if you haven't gotten a chance to watch it.
