Barrages across the Solway Firth, Morecambe Bay, and the Mersey and Dee estuaries in the northwest UK could provide more than 5% of the nation’s electricity and meet half the region’s electricity, a study by engineers at the University of Liverpool has found.

U.S. scientists concerned about carbon dioxide (CO₂) leaks from sequestration attempts have been pursuing the option of natural chemical reactions within the earth to turn the carbon back into a solid, and they have identified an abundant supply of large rock formations around the world that could be used a vast sink for the heat-trapping gas.

Geothermal energy in Europe may have been used for centuries — it was popularized by the Romans and adopted by the Turks — but geothermal-generated electricity was first produced at Larderello, Italy, in 1904. Since then, its growth on the continent has shot up to 820 MW. But, according to the European Renewable Energy Council, the resource’s full potential has barely been harnessed.

Swiss power technology group ABB, which pioneered gas-insulated switchgear 50 years ago, in April announced it had commissioned switchgear rated to handle 1,100 kV. The development marks the biggest leap in capacity and efficiency of AC power transmission in more than two decades.

Gas hydrates, a form of natural gas that forms when methane from the decomposition of organic material comes into contact with water at low temperatures and high pressures, could play a role — even if a small one — in future fuel supplies, researchers attending a March meeting organized by the American Chemical Society suggested.

Emerson Process Management launched a new extreme temperature version of its Rosemount 2130 vibrating fork liquid level switch that is designed for use in extreme temperatures — from – 94F to 500F (–70C to 260C). The new version includes a low-density option suitable for liquids with specific gravity down to 0.5 (500 kg/m ³). In addition to built-in fault-monitoring/self-checking diagnostics to detect corrosion of the forks or any internal or external damage or breaks in the internal electrical wiring, it features a "heartbeat" LED, which provides instant visual indication that the unit is operational. The unit requires no onsite calibration and is available in 316L stainless steel, corrosion-resistant alloy C wet side, or a range of other stainless steel and aluminum options.

Sweden’s SKF Reliability Systems introduced the SKF Microlog Analyzer AX, an advanced vibration-monitoring technology. With simultaneous triaxial or four-channel vibration measurement capability, the unit speeds up data collection and saves time in monitoring rounds. The 806 MHz Xscale processor also means faster real-time rate and display updates. An available range of application modules allows users to create a custom device to perform several advanced tasks, such as impact tests, digital recording, modal analysis, transient phenomena analysis, and quality inspections.

Schaffner’s filter series now includes ECOsine active harmonics filters — compact, digital units that continuously measure and analyze disturbances in the power network and provide an exactly opposite compensation current. In doing so, the filters actively adapt to changing network topologies and respond in less than half a millisecond, before damage from the disturbances can occur. The improved power quality of the new filters minimizes the risk of downtime and process interruptions.

DW Global Group’s recently announced dry bulk hopper mini-silo system — comprising one or more reusable, translucent containers — is designed for companies wanting to replace fiber drums, cardboard boxes, wood pallets, and super sacks. The rugged plastic containers — lids included — multitask as shipping, storage, and dispensing systems. Each hopper has a valve at the bottom for easy flow of material from hoppers to the manufacturing machine. The system allows for stacking of up to three units with a total weight of as much as 2,400 pounds. According to DW Global, the investment for a multi-purpose dry bulk hopper system can be "as little as $5,000 to $10,000, with a return-on-investment in less than a year." (www.dwglobalgroup.com)

The "TCS Cheetah" air-powered hoist from Harrington Hoists Inc. is now available in two new capacities: the ¼-ton TCS250C/P and the 1-ton TCS1000C/P-2. Built for speed, the units are adjustable to fit all lifting requirements, particularly fast-paced or repetitive lifting applications. Additional features include a compact, lightweight aluminum body with good headroom, a disc brake for reliable load support, a vane monitor for very fine feathering control, and an unlimited duty cycle for continuous operation.
