Temporary tattoo lactate sensor converted into sweat-powered biobattery

By - August 14, 2014
Last year, researchers at the University of California, San Diego (UCSD) unveiled a sensor imprinted on a temporary tattoo that, when applied to the skin, is able to continuously monitor lactate levels in a person's sweat as they exercise. Now the research team has leveraged the technology to create a biobattery powered by perspiration that could lead to small electronic devices being powered by sweat. Read More

Work was recently completed on a big, bold, and presumably very expensive architectural project – and for a change, it's not located in Dubai or China. The Singapore Sports Hub is a mammoth new sports complex containing the East Asian city state's new National Stadium: a 55,000 capacity venue that boasts the notable achievement of being the world's largest dome structure.

Tofu ingredient could clean up solar cell recipe

By - June 29, 2014
Tofu has long been touted as a good way to clean out your insides, but now a researcher at the University of Liverpool says an ingredient in tofu could also be used to clean up solar cells. The hope is that the naturally occurring substance could replace a key ingredient in thin film solar cells that is highly toxic and expensive to produce. Read More

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

By - June 3, 2014 7 Pictures
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).

GE uses plastic surgery on wind turbine blades for more power

By - May 26, 2014 2 Pictures
Sometimes progress can be its own worst enemy, with early adopters being stuck with obsolete equipment that leaves them with the choice of living with out-dated technology or an expensive replacement. The green energy field isn’t immune to this, and as part of a US$2 million renewable energy project, GE has developed a way to make smaller, less efficient wind turbines into bigger more efficient ones with a bit of plastic (or carbon composite) surgery.
