The Pentagon is aggressively looking for alternatives for fuel. Not only is it a matter of of money, but the Washington Post is reporting that about half of the U.S. military casualties in Iraq and Afghanistan are related to attacks with improvised explosive devices on convoys, many of which are carrying fuel. A month ago, 3,426 service members had been killed by hostile fire in Iraq, 1,823 of them victims of IEDs. Brig. Gen. Steven Anderson, director of operations and logistics for the Army, told the Post, the best reason to do it is that it saves lives.
