Military Testing Jet Engines Not Powered By Oil-Based Fuel

From the NY Times:

In a series of tests — first on engines mounted on blocks and then with B-52's in flight — the Air Force will try to prove that the American military can fly its aircraft by blending traditional crude-oil-based jet fuel with a synthetic liquid made first from natural gas and, eventually, from coal, which is plentiful and cheaper.

While the military has been a leader in adopting some technologies — light but strong metals, radar-evading stealth designs and fire-retardant flight suits, for example — any effort to hit a miles-per-gallon fuel efficiency rating has taken a back seat when the mission is to haul bombs farther and faster or push 70-ton tanks across a desert to topple an adversary. (The Abrams tank, for example, gets less than a mile per gallon under certain combat conditions.)

"Energy is a national security issue," said Michael A. Aimone, the Air Force assistant deputy chief of staff for logistics.

The United States is unlikely ever to become fully independent of foreign oil, Mr. Aimone said, but the intent of the Air Force project is "to develop enough independence to have assured domestic supplies for aviation purposes."

By late this summer, on the hard lake beds of the Mojave Desert, where the Air Force tests its most secret and high-performance aircraft, a lumbering B-52 is scheduled to take off in an experiment in which two of the giant bomber's engines will burn jet fuel produced not from crude oil but from natural gas. The plane's six other engines will burn traditional jet fuel — just in case.
