Energy crop producer Ceres Inc. plans to market its new agricultural seeds and traits under the trade name Blade Energy Crops in the U.S. The first products to be sold under the brand are currently being multiplied for spring 2009 sowing. They include switchgrass cultivars developed specifically for biofuels, EG 1101 and EG 1102, as well as high-biomass types of sorghum.
Because of their high yields, energy crops can produce more fuel per acre than first-generation biofuel crops and further mitigate greenhouse gas emissions since the new crops require fewer inputs and actually build new topsoil. Ethanol made from switchgrass produces 90 percent less greenhouse gas emissions than petroleum and nearly five times more net energy than starch-based ethanol. Further improvements are likely as breeders introduce new seed varieties and innovations in refining technology are commercialized.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicleís parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but thatís just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
Design engineers need to prepare for a future in which their electronic products will use not just one or two, but possibly many user interfaces that involve touch, vision, gestures, and even eye movements.
