It’s the new secret weapon fueling the US military. A hardy plant capable of growing in poor soil, camelina sativa produces a bio-fuel that’s now the focus of the US Navy’s drive for alternative fuels in its planes.
Last week an F/A-18 Super Hornet flew from the Naval Air Station at Patuxent River, Md., powered by a 50/50 mix of aviation fuel and camelina, also known as wild flax. It was the first supersonic fighter to fly on a bio-fuel mix. The event was celebrated by US Navy Secretary Ray Mabus on the Navy’s new official blog, also launched last week .
