I'm pretty sure the mining industry should be ALL OVER THIS... and probably isn't, not even a little. Just from a safety standpoint, the need for ventilation, diesel particulate in the air, generators with exhaust and so on... just from these few standpoints alone, they should be all over this like white on rice.
http://www.sciencedaily.com/releases/2009/01/090126100645.htmScienceDaily (Jan. 29, 2009) — A team of scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, in collaboration with researchers from the University of Delaware and Yeshiva University, has developed a new catalyst that could make ethanol-powered fuel cells feasible. The highly efficient catalyst performs two crucial, and previously unreachable steps needed to oxidize ethanol and produce clean energy in fuel cell reactions.
Their results are published online in the January 25, 2009 edition of Nature Materials.
Like batteries that never die, hydrogen fuel cells convert hydrogen and oxygen into water and, as part of the process, produce electricity. However, efficient production, storage, and transport of hydrogen for fuel cell use is not easily achieved. As an alternative, researchers are studying the incorporation of hydrogen-rich compounds, for example, the use of liquid ethanol in a system called a direct ethanol fuel cell.
“Ethanol is one of the most ideal reactants for fuel cells,” said Brookhaven chemist Radoslav Adzic. “It’s easy to produce, renewable, nontoxic, relatively easy to transport, and it has a high energy density. In addition, with some alterations, we could reuse the infrastructure that’s currently in place to store and distribute gasoline.”
