An interesting venture was announced recently between the United States and China that could be deemed "a bit nutty". The venture focuses on research to develop algae or oily nut biofuels that can be used by Chinese airlines. Boeing is just one of the organizations participating in the research partnership.  (see the article)

Interestingly in 2008, Boeing also participated in a similar joint venture with Air New Zealand (read article). The oily nuts of choice are from the non-edible jatropha plant as they are not edible crops and don't encroach on crop lands. According to the article, Boeing has been working closely with the Hawaiian Agricultural Research Centre to research and cultivate jatropha for mass airline commercial use.

Frequent fliers relax - the peanuts are safe.
