Turbine

Researchers at at Drexel University have developed a metallic nanocoating derived from a virus of the tobacco plant that could lead to more efficient steam production, improving the performance of steam turbines, air conditioning and electronics cooling systems. Read More
One of the problems with building the world's largest and most powerful gas turbine is that you need to build a test bed to match. Having invested US$1 billion in its 500,000 bhp 9HA Harriet gas turbine, GE had to fork over another US$185 million to build a full-load test bed at GE Power & Water in Greenville, South Carolina that can handle the grid-busting output of Harriet.

Turbine blades for use in jet engines need to be made of a hard, unyielding exotic material made to exact specifications, which means the drilling of tiny cooling holes in the blades runs the risk of ruining them. To prevent this from happening, GE is combining the heat of the laser beam with the cooling of the water jet to drill holes without weakening the blades. Read More
It’s a tough row to hoe for young salmon in the Pacific Northwest as they make their perilous journey from upriver to the ocean. Besides hungry birds and sea lions, the regions many hydroelectric dams and their swirling turbines produce manmade currents and other obstacles that make it challenging for the fish to navigate. But now with the help of an artificial Senor Fish created by the Pacific Northwest National Laboratory (PNNL), existing larger dams and newer, smaller hydroelectric facilities can become more fish-friendly.

GE is looking to a new generation of carbon-fiber composites to make the fan blades for its GE9X jet engine. That engine is being developed for the Boeing 777X passenger airplanes that are set to enter service in 2020 and the new blades promise to provide larger, lighter engines with greater fuel efficiency.

Researchers at Australia's CSIRO have claimed a world record for the highest temperatures ever achieved using solar energy to generate "supercritical" steam at its solar thermal test plant in Newcastle, Australia. Featuring more than 600 directional mirrors (heliostats) directed at two towers housing solar receivers and turbines, the researchers produced the steam at a pressure of 23.5 MPa (3400 psi) and 570° C (1,058° F).

Last year, the Airbus A350 XWB took to the air for the first time. Eleven months later, Rolls-Royce announces that the first production Trent XWB turbofan engine that powers the plane has left the factory and is on its way to Toulouse, France to be installed in a Qatar Airways A350 XWB. According to Rolls-Royce, Qatar airways has ordered 80 of the aircraft and the “world's most efficient aero engine” engine is the first of 1,600 ordered worldwide by 40 airlines around the world.

Winds are stronger and steadier at higher altitudes, that’s why the Buoyant Air Turbine (BAT) from Altaeros is pushing to be the highest wind turbine in history. Already tested to 500 feet off the ground in 45 mph winds, this helium-filled shell with a wind turbine in the middle is soon shooting for a world record 1,000 ft float. Packing down into a shipping container for transport, the BAT is being proposed as a quickly deployable tethered power source for remote areas and emergency zones. Read More
Australian Daz Fellows wants to ensure proper nomenclature is used when describing his modified street luge. Sporting twin-turbines with a combined output of 537 lb of thrust, and a custom formed board composed of carbon fiber, Daz has made clear that the conveyance he'll be climbing aboard when he shoots for a world record attempt of 300 mph (482 km/h) next year is a "jet luge."

Three DARPA-funded research teams have completed a foundational study of chip-scale vacuum pumps by inventing three very different approaches to removing air from a sample chamber with a volume of one cubic millimeter, which is about one-tenth the volume of a grain of rice. These new technologies will enable many micro-scale devices which require a vacuum or a controlled flow of gas, such as Lab-on-a-Chip sensors, radio frequency MEMS switches and microscopic vacuum tubes.
