Robot climbs up pipes to clean power station boiler tube walls

Cleaning power station boiler tube walls is a dirty and troublesome job that is not only hazardous, but can generally only be done during station down times to minimize the risk to human cleaners. To help address this problem, a new robot has been developed that is specifically designed to climb and clean boiler tube walls, even in confined spaces and at elevated particulate levels.Read More

CSIRO sets world record in generating "supercritical" steam using solar power

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).

National Grid report challenges wind energy critics

Squirreled away beneath a recent Telegraph report on the subtleties of badger-culling in the UK was this intriguing morsel of wind energy news, which would seem to challenge the idea that intermittent energy sources such as wind play havoc with grid management. For the 23,700 gigawatt-hours of electrical energy generated by wind in the UK between April 2011 and September 2012, only 22 GWh of electrical energy from fossil fuels "was needed to fill the gaps when the wind didn't blow," it reports. Gizmag contacted the UK National Grid to find out the details.Read More
