Ben Shoemate's Notebook

(PhysOrg.com) -- John Fleming of SilverEagles Energy and Tim Maxwell from Texas Tech University, say they have developed a way to make ammonia that is cheap enough so that it could be used as fuel for cars. If their claims turn out to be true, many consumers might consider switching over because ammonia, when burned in an engine, emits nothing but nitrogen and water vapor out the tailpipe. And if thatÂ’s not enough incentive, they claim they can make the ammonia for just 20 cents a liter (approximately 75 cents a gallon).
