Turbine Takes the Heat

Turbine Takes the Heat A sound strategy for optimizing reliability of older steam turbines under the harsh operating conditions of geothermal power systems is modernization. Experiences gained from geothermal unit overhauls and upgrades are synthesized in a Renewable Energy World article. Breakthroughs and geothermal-specific best practices improve efficiency and extend service life for older steam-field turbines. Address erosion and component wear with modern airfoil materials, and modify turbine steam-paths to accommodate expected steam-field resource declines in flow, pressure, and temperature. Modernization can lead to recovery of original output or even to increases in unit capacity.

Solar Building Blocks: Video

Solar Building Blocks: Video A prefabricated solar structure can be quickly deployed for shelter during emergencies, health clinics in rural areas, or other uses. Watch as each solar panel-covered LifeVillage unit unfolds to provide 50 kW of power for water pumping, lighting, and refrigeration. The shipping container-based system can exploit solar energy virtually anywhere.

They Clean Their Own Windows

They Clean Their Own Windows Dust is a nuisance and efficiency drain for large-scale solar power operators. EurekAlert reports that technology devised for NASA space missions was borrowed to develop terrestrial solar panels that clean themselves. As dust is detected, sensors energize a transparent, electrically sensitive panel cover and an electrical wave pushes particles away.

Take a Crack at Self-sufficiency

Take a Crack at Self-sufficiency Fuel cell technology represents the optimal solution to waste and energy problems at one California egg ranch. Methane produced from the poultry waste stream in an anaerobic digester will drive a 1.4 MW fuel cell. The electricity will be used on-site, allowing the farm to duck both waste disposal and spiraling energy costs.

Hail the Hybrid Taxi

Hail the Hybrid Taxi To achieve blue skies before hosting the 2012 Olympics, engineers are turning London's black cabs into clean green machines. Twenty zero-emission proton exchange membrane fuel cell hybrid taxis will replace diesel-powered polluters. The prototype features 30 kW net power output, lithium ion battery capacity of 15 kWh, and 3.7 kg of hydrogen storage.

Titanic Tidal Turbine

Titanic Tidal Turbine The world's largest rotor diameter tidal turbine was unveiled and installed last month in 35 m of water off Orkney, Scotland. The 130 ton AK1000 will dispatch 1 MW of predictable power at a 2.6 m/second water velocity after a three-year commissioning period. The turbine can supply power to more than 1,000 homes.

Renewable Energy for Retail

Renewable Energy for Retail The IKEA store under construction in Centennial, CO, is the first for the Swedish retailer in the U.S. with geothermal heating and cooling. The heat pump system will exploit moderate temperatures at 500 ft depth. Performance monitoring by the DOE National Renewable Energy Lab. will provide useful data for future commercial applications.

Cost Cleanup for Batteries

Cost Cleanup for Batteries A one-step method for fabricating lithium manganese phosphate cathodes should lead to low-cost alternatives to metal oxides in lithium ion batteries. After mixing with electrode ingredients to promote crystal alignment, melted paraffin and oleic acid boiled off as temperature increased. With a conductive carbon backing, the resulting nanoplates held about 150 milliAmp hours/g of material.

Non-stink Bug: Video

Non-stink Bug: Video Methane generated by a sewage treatment plant in Bristol, UK, fuels the Volkswagen Beetle showcased in a BBC News video. The vehicle could travel 10,000 miles (16,100 km) on the yearly waste-derived fuel from 70 households. Bio-Bug averages 5.3 miles per cubic meter of biogas, showing that it has a lot of get-up-and-go.

A Sunny, Windy Forecast

A Sunny, Windy Forecast An optimistic energy scenario espoused by Nobel laureate Walter Kohn of the University of California is driven by the twin threats of global warming and diminishing oil and gas supplies. The global response to these trends is already underway: research into clean, affordable energy. The momentum experienced over the last decade in wind and photovoltaic energy production should continue. These renewable energy forms will become dominant worldwide in the SOL/WIND era.

Churn Out Some Fuel

Churn Out Some Fuel Rather than waste the 800 lb butter sculptures gracing the annual Pennsylvania Farm Show, organizers handed the likenesses of Benjamin Franklin and the Liberty Bell over to research. A biofuel maker tested its process for converting low-value fats into biodiesel. About 75 gal of mixed biodiesel-bunker fuel were produced. The method might be applicable to agriwaste conversion rather than expensive (and artistic) butter.
