Engineers at Purdue University and Sandia National Laboratories have developed a technique that uses sensors and computational software to constantly monitor forces exerted on wind turbine blades. Their achievement could one day improve the efficiency of wind turbines by providing the blades’ "smart" structure with necessary data to adjust to rapidly changing wind conditions.

The intensifying spotlight on renewable energy seems to be casting a brighter light on the energy storage problem, with lawmakers, researchers, and investors scrambling to seek out the most feasible solution to bridge the intermittent nature of renewable power sources.

Just as reports emerged earlier this year that NASA had abandoned, for lack of financial resources, its research into space-based solar power that would be harnessed via orbiting solar arrays beaming microwaves to earthly receivers, California’s Pacific Gas & Electric Co. (PG&E) wrote the California Public Utilities Commission (PUC) requesting its approval of a power purchase agreement from a similar technology.

In the world of North American Electric Reliability Corp. (NERC) Reliability Standards, each company (entity) that must comply with the standards determines for itself the scope and size of its compliance program, based on the scope and size of its operations.

Increasingly fierce competition driven by deregulation and privatization is putting downward pressure on power plant operations and maintenance (O&M) budgets. Recently, lower natural gas prices have pushed natural gas – fired combined-cycle plants higher up in many utilities’ dispatch order in some regions, a welcome change from the twice-a-day cycling experienced by some plants during the past few years. However, with more operating hours comes more interest in plant operating availability, and that means increased emphasis on reliable gas turbine operation.

The recently released EX-5165 Sensor/Transmitter from ENMET Corp. is a three-wire 4-20 mA sensor for the detection of carbon dioxide in ranges from 0 to 500 ppm and 0% to 100% by volume. It also features a 24 VDC loop-powered transmitter. The nondispersive infrared sensor continuously monitors high concentrations of the gas, and it can […]

Caterpillar Inc. introduced a new family of remanufactured generator ends for standby, prime, and continuous power applications. The C32 and 3500 series Caterpillar engines have been used for applications ranging from distributed generation to prime power for remote communities. The first wave of remanufactured generator ends includes 34 part numbers, which are available worldwide in […]

Rotork Process Controls introduced the SM-6000 S2, an electric rotary actuator for a wide range of heavy-duty damper drive applications found in power plants. The actuator provides high speeds and high torque for continuous modulating duty. It also offers positioning accuracy and can operate well in harsh and rugged environments. The SM-6000 S2 includes an […]

Chicago Blower has developed a series of 16 higher-pressure blowers that are suited to combustion air, aeration, cooling and drying systems, and other high-volume processes. The blowers support pressures of up to 91-inch water gauge and volumes of up to 18,000 cubic feet per minute. Features include a lightweight aluminum alloy wheel design to reduce […]

Washington-based software developer Dynamic Systems Inc. launched the Basic Tool Manager, a software based on barcode technology, which has been developed for companies that want to reduce the loss of tools and save time tracking down equipment and tools. Using a wireless barcode reader, users can scan a personnel badge and then a piece of […]
