A wider, 66-in. body design makes room for high-performance acceleration—as military vehicles go—with the second-gen Aggressor set to rev from 0-40 mph in four seconds and top out at 80 mph. But speed is not the main attraction here; stealth is. The Aggressor’s design provides battery-only operations, allowing it to switch into “silent mode” with a reduced thermal signature.The silent mode could help protect U.S. troops from some types of attacks, but saving fuel may be equally important.

“We believe that the AMV program offers an innovative solution as a long-range reconnaissance vehicle that fills a technology gap for the U.S. Army in its national defense efforts while reducing its fuel logistic burden,” said Alan Niedzwieki, president and CEO of Quantum Fuel Systems Technologies, which the Army contracted for both versions of the Aggressor.They didn't mention anything about protecting the environment, because I guess that would have sounded silly. But it does make me think about the bizarre prospect of "environmentally friendlier war." Will we one day see hydrogen-powered drone planes dropping bombs made from recycled materials? Soldiers wearing gear made from hemp, living in solar-powered bamboo barracks? It could happen eventually, if only to save on costs.
Update: Nellis Air Force Base in Nevada is constructing "North America's Largest solar photovoltaic power system" with 70,000 solar panels. Read the article.
