US Powering Drones With Biofuels

This must be a comfort to the human beings and the families whom the drones destroy.

The first operational outing for the Navy's biofuel venture will be in 2012, at the vast Rim of the Pacific naval exercise. Four ships will sail under the 50-50 blends, along with a nuclear-powered aircraft carrier, on which all the planes will fly on the same mix. A larger strike group of 11 ships will follow in 2016.The Navy has also tested a hybrid electric propulsion system on the 250m-long USS Makin Island. It saved $2m in fuel costs on its maiden voyage, from the Mississippi round South America and up to San Diego. Hicks estimates the lifetime saving at $250m. MORE
