Going green makes military sense to the U.S. Army. Self-sufficient vehicles and base camps require fewer supply convoy runs that stretch logistics lines thin across hostile territory. The Army's new "zero-footprint" concept for a camp includes a package of very cool technologies.
Soldiers could eventually obtain their drinking water from vehicle exhaust, based on water-purification technologies being developed by the U.S. Army's TARDEC and DARPA labs. Garbage and waste produced by camps could also become new sources of energy.
Mercedesâ€™s Bionic concept takes small-car thinking to new depths

When Mercedes-Benz began to contemplate its next generation of high-efficiency small cars, it sought aquatic inspiration. But instead of considering obvious undersea hot rods like sharks, the Mercedes team turned to a fish that resembled a car: the tropical boxfish. A native of the Indo-Pacific region, the Ostracion cubicus is surprisingly slick. Wind-tunnel testing of a clay model revealed a drag coefficient (Cd) of just 0.06, startlingly close to the ideal 0.04 of a water droplet.
