World's largest dome structure completed in Singapore

By - July 21, 2014 17 Pictures
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.

Solar Wind Energy's Downdraft Tower generates its own wind all year round

By - June 18, 2014 1 Picture
When we think of wind power, we generally think of huge wind turbines sitting high atop towers where they can take advantage of the higher wind speeds. But Maryland-based Solar Wind Energy, Inc. is looking to turn wind power on its head with the Solar Wind Downdraft Tower, which places turbines at the base of a tower and generates its own wind to turn them.

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.

Could a space-based solar farm become a reality by 2040?

By - May 13, 2014 2 Pictures
Space-based solar power seems like an idea from a Star Trek script, but given the uncertain future of its power generation industry, Japan stands to gain as much as anyone by exploring this potential source of renewable energy. The disaster at Fukushima, limited access to fossil fuels and advances in technology has, at least in the eyes of the Japan Aerospace Exploration Agency (JAXA), added further weight to the notion of a space-based solar power system. The agency is developing a complex roadmap involving a 1 GW extraterrestrial solar farm, a microwave beam and a man-made island in the Tokyo harbor which could be used collect solar energy in space and supply power to Earth by 2040.
