Rt: I expect it would be cleaner than bio-diesel – the simple methane molecule (CH4) burns very cleanly. Bio-diesel is already clean, though, particularly in regard to particulates, compared to fossil fuels.

Sietch people: What’s license do you post under? Would you consider setting a policy of releasing blogs (or even everything on your site) under the GFD License (same as Wikipedia and many other wikis such as Appropedia)? That would mean anyone could copy it as long as they gave credit.

I’d love to be able to just put something like this into Appropedia – copy and paste, spending another 30 seconds on formatting and adding a notice template crediting The Sietch, and including the URL. This would help improve the quality of Appropedia’s resource bank, as well as raising your profile among like-minded people, and helping your search engine ranking. What do you think?

I doubt you will see much bio-methane on the market. It seems most places that create it use it on-site. Perhaps if there is enough external demad that will change. Even so, I understand just switching to methane from petroleum results in tremendous emissions reduction. I wonder if it’s lower than bio-diesel?

It will be interesting to see what range they can get per tank compared to the compressed version. If they get the commercial fleets to convert cetainly there will be others that will investigate as well. Promising news for competition in the transportation fuel area.
