Energy-Efficient Forestry Machinery
Stockholm, Sweden (SPX) Jun 01, 2009 Sveaskog has started using the first example of the El-forest F14 forestry machine, the world's first forwarder to utilize electric-hybrid technology. The forwarder was developed by El-forest AB with assistance from the Volvo Technology Transfer venture-capital company. It will be on demonstration at the Elmia Wood trade fair in Jonkoping, Sweden on June 3-6, along with a wide range of other forestry machinery from Volvo Construction Equipment, as well as other products from the Volvo Group for the forest industry. The electric hybrid technology in the El-forest F14 has attracted great interest among forest companies due, among other features, to the possibility of reducing fuel consumption by 20-50%, which sharply reduces carbon-dioxide emissions. "In addition to the significant fuel reduction, productivity and operator environment were prioritized, and consequently, profitability for our customers," says Per Wassen, Chairman of El-forest and Investment Director at Volvo Technology Transfer, which is owned by AB Volvo. The El-forest F14 is a series hybrid involving a smaller diesel engine that drives a generator that, via batteries, provides electric energy to electric motors in the forwarder's six wheels. "The drive technology developed has great potential, since, for example, the diesel engine could be replaced by alternative biofuel engines or even with fuel cells in the future," says Per Wassen. The El-forest F14 is lighter than a conventional forwarder of the same size, but can cope with the same load. There is less impact on the forest environment due to a patented frame structure that enables all electric-driven wheels to follow the same track with adapted speed. Volvo Technology Transfer AB focuses on developing and supporting new businesses relevant to the Volvo Group. Part of the effort is to invest in companies and projects that are technologically and commercially attractive. Share This Article With Planet Earth

Regular Light Bulbs Made Super-Efficient With Ultra-Fast LaserRochester NY (SPX) Jun 01, 2009 An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester. The process could make a light as bright as a 100-watt bulb consume less electricity than a 60-watt bulb while remaining far cheaper and radiating a more pleasant light than a fluorescent bulb can. The laser process creates a unique array of nano- and ... read more |
