Like the little engine that could, the University of Nevada, Reno experiment to transform wastewater sludge to electrical power is chugging along, dwarfed by the million-gallon tanks, pipes and pumps at the Truckee Meadows Water Reclamation Facility where, ultimately, the plant’s electrical power could be supplied on-site by the process University researchers are developing. “We are very pleased with the results of the demonstration testing of our research,” Chuck Coronella, principle investigator for the research project and an associate professor of chemical engineering, said. “The process to dry the sludge to make it burnable for a gasification process, which could then be transformed into electricity, is working very well. This is an important step for our renewable energy research, processing about 20 pounds an hour of sludge in a continuous-feed system to produce about 3 pounds an hour of dried powder.” The team of researchers custom built the processing machine in a lab at the University and brought it to the plant for testing. It uses an innovative process with relatively low temperatures in a fluidized bed of sand and salts to economically produce the biomass fuel from the gooey sludge. Read full release here.

Imagine outfitting your house with small, affordable solar panels that plug into a socket and pump power into your electrical system instead of taking it out. That's the promise of a Seattle, Washington-based start-up that is working to provide renewable energy options -- solar panels and wind turbines -- for homes and small businesses. The panels cost as little as $600 and plug directly into a power outlet. The company, Clarian Power, aims to be the first to bring a plug-in solar power system to the market, in 2011. Clarian's president, Chad Maglaque, says the company's product is different from existing micro-inverters, which convert solar panels' power into AC current. Maglaque says his system has built-in circuit protection, doesn't require a dedicated electrical panel and plugs directly into a standard electrical outlet. Source: CNN
Atlantis Resources Corporation (“Atlantis”) unveiled the largest and most powerful tidal power turbine ever built, the AK1000™, yesterday at Invergordon, Scotland. The AK1000™ is due for installation at a dedicated berth at the European Marine Energy Centre (“EMEC”), located in Orkney, Scotland later this summer. Despatching 1MW of predictable power at a water velocity of 2.65m/s, the AK1000™ is capable of generating enough electricity for over 1000 homes. It is designed for harsh weather and rough, open ocean environments such as those found off the Scottish coast. The turbine incorporates cutting edge technology from suppliers across the globe, has an 18 meter rotor diameter, weighs 1300 tonnes and stands at a height of 22.5 meters. The giant turbine is expected to be environmentally benign due to a low rotation speed whilst in operation and will deliver predictable, sustainable power to the local Orkney grid.
