Last month, AE Biofuels (Cupertino, Calif.; www.aebiofuels.com) opened an integrated cellulose-and-starch ethanol demonstration facility in Butte, Mont. If operated at full capacity, the plant could produce 150,000 gal/yr of ethanol. The plant uses ambient-temperature cellulose-starch-hydrolysis (ATCSH) enzyme technology to optimize process conditions for multiple feestocks. Non-food feedstocks used by the...

Controlling particle size is critical in alumina processing, especially when alumina crystals are precipitated from Bayer liquor — a highly caustic solution where bauxite is dissolved to produce alumina. The ability to control the conditions of the precipitation process through online monitoring of particle size can improve production and quality. With this in mind, a group from CSIRO Minerals...

Engineers at MIT (Cambridge, Mass.; www.mit.edu) are developing solar concentrators that have the potential to increase the electrical power output from solar cells by a factor of more than 40. Instead of actually focusing the light, as in systems being developed elsewhere (see also below), MIT’s device makes use of a coating of two or more dyes on the surface of a pane of glass or plastic, with...

Optoacoustic gas detection determines gas content via the measurement of acoustic pressure waves that are propagated as a gas is irradiated under an appropriately tuned light. A gaseous-mixture sample passes through a membrane into a measurement cell, which contains an infrared light source and a microphone. Incident light modulated at a specific frequency is briefly absorbed as intermolecular energy by...

The production of hydrogen by water splitting promises to become less expensive through a solar-energy process being developed at Penn State University (University Park, Pa.; www.psu.edu). Like other photoelectrochemical methods, the process splits water into its two components, generating O2 at the anode and H2 at the cathode. However, the configuration of the system is different. Developed by Craig...
