Tofu ingredient could clean up solar cell recipe

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

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

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?

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.Read More

Jaguar installs UK's largest rooftop solar array

The rooftops of automotive manufacturing plants have proven fertile ground for solar arrays with Audi, Ferrari and Renault installing extensive fields of solar panels at their respective facilities. Now Jaguar Land Rover has got on board with the largest rooftop solar panel array in the UK sprouting from its new Engine Manufacturing Centre in South Staffordshire.Read More

Energy-producing Honda Smart Home gives more than it takes

With homes and light-vehicles accounting for roughly 44 percent of total greenhouse gases emitted in the US, neutralizing these emissions would certainly go a long way towards a clean energy future. What if these sources of pollution could not only be nullified, but play an active role in reducing our environmental footprint? Such is the thinking behind the Honda Smart Home US unveiled last week, which generates enough solar energy to power both car and home, with a little left over to feed back into the grid. Read More

Could Earth's infrared emissions be a new renewable energy source?

Could it one day be possible to generate electricity from the loss of heat from Earth to outer space? A group of Harvard engineers believe so and have theorized something of a reverse photovoltaic cell to do just this. The key is using the flow of energy away from our planet to generate voltage, rather than using incoming energy as in existing solar technologies.Read More

Orchid House concept inspired by Taiwan's greenhouse technologies

In high-density areas like the Taiwanese capital of Taipei, people have long looked to expand vertically to make use of the limited land, resulting in a lack of vegetation, high humidity and high energy usage. According to Unicode, a team of Taiwanese architects and designers, 50 percent of the county's housing constructions are either common multiple-story rowhouses or larger duplex apartment buildings, many of which have illegal makeshift shelters on their rooftops to provide extra living space. Unicode has developed a concept house which would give these shelters a greenhouse-inspired makeover, shifting reliance to renewable energy sources and improving Taipei's sustainability in the process.
