Brazilian firm Tecbio, NASA, and Boeing have agreed to work together to produce biokerosene for aviation fuel. It's a short article, but I thought it was interesting because it touches two of my interests: aerospace and replacements for petroleum products. When I think of replacing our (i.e., US) dependence on petroleum, my mind always sticks on automobiles. I am entirely dependent on them (when I'm at home). But I also depend on aviation, else I wouldn't be here in France—I needed the plane to jump the ocean and much of the background I did to get accepted here was done by traveling.
