With the proliferation of electronic and electrical equipment on the
battlefield, there's a growing power shortage out there. So the U.S. Army has
developed a new version of its 13 ton HEMTT (Heavy Expanded Mobility Tactical
Truck). The HEMTT A3 uses its diesel engine to drive a generator, which
produces over 100 kilowatts of power. Normally, this electricity runs electric
motors that move the truck. But put the truck in park, and the power is
available for other uses, like powering a military base in a remote location.
The HEMTT A3 has already undergone nearly 20,000 kilometers of on, and off,
road testing. The main concern at this point is that the new equipment is
rugged enough for regular army use. This includes surviving heavy use for
twenty years or more. In 2005, a HEMTT A3 prototype was sent to New Orleans,
after Hurricane Katrina hit, and provided power for a hospital. If this new
"Propulse" technology survives its remaining tests, it will be installed in
other models of army trucks as well.
