sional who has worked in the field or run around a plant could vouch for the utility of a computer or handheld battery that could hold a charge 10 times as long, and perhaps never need to be replaced. 8. Cementless Concrete Georgia Tech researchers have developed a process to use coal ash to produce a concrete material that uses no cement. The end product is strong and lightweight, along with other advantageous characteristics. Coal-burning power plants must dispose of over 125 million tons of ash each year. Mulalo Doyoyo, an assistant professor in Georgia Tech’s School of Civil and Environmental Engineering developed a trademarked material called Cenocell that is a proprietary mixture of the bottom, or fly, ash mixed with organic chemicals to form the new material. Sand and aggregate materials as well as the cement are not required. The resulting material can withstand pressures up to 7,000 psi. It is also fireproof. It can be shaped in molds and machined as needed for building construction projects. Doyoyo believes the material would reduce the use of cement, thus reducing “ Engineers in 2008 built walls that can clean the air on contact, or generate electricity… ” emission of CO2 gas that is normally given off during its manufacture. He expects the product will cost an average of $50 per cubic yard to produce. Anticipated uses for the product are building and construction, transportation, aerospace and protective installations. Doyoyo will next be presenting his findings at the World of Coal Ash convention, May 4-7, 2009 in Lexington, Ky. 9. Power to the Peaches Caye Drapcho, a biosystems engineer at Clemson University in South Carolina, is investigating a bacterium that produces hydrogen. The microbe is called Thermotoga neapolitana and it has a Lakes Environmental Software Air Dispersion Modeling - Emissions Inventory - IT Solutions New!
