Biofuels That Avoid Harm to the Food Supply

Biofuel manufacturers seem to be making great progress in the application of their combustibles to aircraft use, while gaining momentum in the amounts produced.  Whether these will be economically and environmentally viable remains to be seen, but early indicators show hopeful signs. Biofuels have several advantages over the ancient plant life that has been squeezed for millions of years to give us eons-old pollution.  They burn cleaner, can be cheaper to produce, and with distributed growth and refinery centers, could reduce the cost and hazards of distribution. Several issues surround the new fuels, though, including the food-versus-energy debate.  The Environmental Working Group (EWG), for instance, has endorsed two widely disparate politicians for a bi-partisan attempt to mitigate problems associated with channeling food stocks into fuel feedstocks. “EWG commends Sens. Dianne Feinstein (D-Calif.) and Tom Coburn (R-Okla.) for taking action to address the environmental, economic and consumer harms that result from diverting corn for transportation fuel. The Corn Ethanol Mandate Elimination Act …

Thunderbirds Are Go With Camelina

The Air Force Thunderbirds F-16 demonstration team will become the first Department of Defense military air show group to fly on bio-fuel when two members of the team have their craft powered by a 50-50 mix of standard JP-8 and camelina-derived bio-fuel.  The flights were scheduled to place at Andrews Air Force Base for the Joint Services Open House on May 20 and 21. The team follows two other uses of camelina in military jets: the Earth Day 2010 flight of an FA-18s (the Green Hornet) and this year’s supersonic flight on the fuel blend by an F-22.  These demonstrations exhibit the interest DOD planners are taking in finding alternative fuels. The Air Force press release makes the overall effects of such changes clear.  “The team will fly with Camelina-based hydrotreated renewable jet fuel as part of the nation’s overall strategy to reduce reliance on foreign energy and establish greater energy security through conservation and use of ‘home grown’ alternative energy sources, said …
