Natural-Gas Autos

Researchers have created carbon briquettes with complex nanopores capable of storing natural gas at a density of 180 times their own volume and at one- seventh the pressure of conventional natural gas tanks. The briquettes are the first technology to meet the 180 to 1 storage to volume target set by the U.S. Department of...
