Just read on Yahoo! News that a research group at the College of Natural Resources at the University of Idaho is working on replacing oil with wood as a primary fuel.
Now, the news report lacks substantial technical information, but my guess is that these guys are using Pyrolysis to generate bio-oil from wood. Of course, I would try to gather some more information from their webpages/publications, but for now, going by the article, pyrolysis seems to be the only way this is possible.
This makes me wonder. What is the purpose of even doing this type of research? I can understand using waste bio material to generate fuel, but cutting trees to generate oil, or as the news report puts it, quicken the natural process of crude oil formation seems a little irresponsible to me. Deforestation is a serious issue, and I doubt that using trees to power our SUVs is going to help solve anything.
I wish that more research was done from a practical viewpoint rather than just to get published.
