Super-low loss quantum energy transport could revolutionize sunlight to energy conversion

By - August 24, 2015

The use of sunlight as an energy source is achieved in a number of ways, from conversion to electricity via photovoltaic (PV) panels, concentrated heat to drive steam turbines, and even hydrogen generation via artificial photosynthesis. Unfortunately, much of the light energy in PV and photosynthesis systems is lost as heat due to the thermodynamic inefficiencies inherent in the process of converting the incoming energy from one form to another. Now scientists working at the University of Bayreuth claim to have created a super-efficient light-energy transport conduit that exhibits almost zero loss, and shows promise as the missing link in the sunlight to energy conversion process.

India's Cochin International to become world's first completely solar-powered airport

By - August 19, 2015 5 Pictures

It may not be the first airport to fit solar panels to its terminals, but India's Cochin International Airport is set to become the first in the world powered entirely by solar. Situated in Kochi, the airport handled 6.8 million passengers in the 2014-15 financial year and forecasts a 300,000-tonne (330,700-ton) reduction in carbon emissions over the next 25 years as a result of the switch to solar.

SunPort tells the grid you want to use solar-generated electricity

By - August 18, 2015 2 Pictures

A new, simple device has been designed for people who, for financial or practical reasons, can't have PV panels on their rooftops, but still want to show their support for solar power and help the industry grow. The amount of electricity used to power a gadget connected to the SunPort plug is offset against solar credits, essentially making your electronic device solar-powered. Kind of.

Project Sunroof calculates rooftop solar potential using Google Maps

By - August 18, 2015 2 Pictures

Ever balked at installing solar panels on your roof because it's pretty damn expensive or you're not sure how much power it would actually generate, or a combination of both? Well, a new venture from Google is aimed at taking the guesswork out of weaning your household off the grid. Powered by Google Maps, Project Sunroof can tell users how much sun is hitting their roof and how much they might be able to shave off their power bills.

Study claims perovskite solar cells can recoup their energy cost within three months

By - August 4, 2015 3 Pictures

Scientists at Northwestern University and the U.S. Department of Energy have found that perovskite cells, one of the most promising solar technologies of recent years, can repay their energy cost over 10 times faster than traditional silicon-based solar cells. The finding confirms that, once issues related to cell longevity are ironed out, perovskite cells could soon bring us solar energy on the cheap, and do so with less impact on the environment over their lifetime.

Solar-powered hydrogen generation using two of the most abundant elements on Earth

By - June 23, 2015

One potential clean energy future requires an economical, efficient, and relatively simple way to generate copious amounts of hydrogen for use in fuel-cells and hydrogen-powered vehicles. Often achieved by using electricity to split water molecules into hydrogen and oxygen, the ideal method would be to mine hydrogen from water using electricity generated directly from sunlight without the addition of any external power source. Hematite – the mineral form of iron – used in conjunction with silicon has shown some promise in this area, but low conversion efficiencies have slowed research. Now scientists have discovered a way to make great improvements, giving hope to using two of the most abundant elements on earth to efficiently produce hydrogen.

Battery juices itself up using light

It's now fairly common to hear about batteries being used to store power generated by solar cells. A group of Indian scientists, however, have eliminated the middleman. They've created a battery that incorporates a titanium nitride-based photoanode in place of a conventional anode, allowing the battery to charge itself using solar or artificial light.

Construction finishes on two floating mega-solar plants in Japan

By - April 23, 2015 3 Pictures
Construction has been completed on two enormous floating solar power plants located in the Nishihira Pond and Higashihira Pond in Kato City, Japan. According to The Kyocera Corporation and the Century Tokyo Leasing Corporation, who partnered up to build the instillations, the combined output of the solar plants will be around 3,300 megawatt hours (MWh) per year, and provide electricity to an estimated 920 households.
