The five-cell metamaterial array developed by Duke engineers that converts stray microwave...

Joining the ranks of devices designed to harvest energy from ambient electromagnetic radiation comes an electrical circuit from researchers at Duke University that can be tuned to capture microwave energy from various sources, including satellite, sound or Wi-Fi signals. The researchers say the device converts otherwise lost energy into direct current voltage with efficiencies similar to that of current solar cells.  Read More

The new 'Ene-Farm' home fuel cell installed in a condominium's pipe shaft with the fuel ce...

Panasonic and Tokyo Gas have continued joint development of their "Ene-Farm" home fuel cell unit, which became the world's first commercialized fuel cell system targeted at household heating and electricity generation when it went on sale in Japan in May 2009. The latest model is aimed at use in condominiums and features a number of modifications to ensure the units meet the more stringent installation standards placed on those buildings.  Read More

Neurio is designed to cut energy consumption by monitoring home appliances

A new product called Neurio has been designed to help people better control their domestic energy usage by monitoring home appliances. The product also allows users to be reminded of domestic tasks involving appliances. In cases of smart appliances, Neurio can detect behavior patterns and program appliances to meet specific requirements.  Read More

The winning house, LISI, by the Vienna University of Technology features a lace-like UV cu...

Team Austria (Vienna University of Technology) has been announced the overall winner of Solar Decathlon 2013 after the closest competition in the history of the event. Second place went to University of Nevada Las Vegas, with the Czech Technical University achieving third place overall.  Read More

Do 'plasmonic nanostructures' hold the key to next-generation solar power?  (Photo: Shutte...

Researchers at the University of Pennsylvania have found a way to harvest energy from sunlight more efficiently, with the help of so-called plasmonic nanostructures. The new findings suggest that plasmonic components can enhance and direct optical scattering, creating a mechanism that is more efficient than the photoexcitation that drives solar cells. The development could therefore provide a real boost to solar cell efficiency and lead to faster optical communication.  Read More

New research examines the economics of storing energy from renewable sources (Photo: Shutt...

True or false: solar and wind power are freely available and clean, and thus should always be stored when they generate more energy than the grid can use? It's easy to assume that renewable energy should never be turned off, but scientists at Stanford have done the math to find the break-even point where storing energy is better than "wasting," or curtailing, that energy, and their findings aren't necessarily as you'd think.  Read More

Energy Box was completed earlier this year (Photo: Pierluigi Bonomo)

Following the earthquake which struck L'Aquila, Italy, on April 6 2009, Pierluigi Bonomo was tasked with building a replacement home for a family. The architect produced a three floor property, dubbed Energy Box, which features an unusual wooden box-like design, and energy-reducing technologies including passive ventilation, and photovoltaic panels.  Read More

Its makers claim that Sprayable Energy will provide a gradual hit of caffeine through the ...

Some people cannot function in the morning without a shot of caffeine to kick start their day, and though caffeine dependency isn't a good thing, the makers of a new product called Sprayable Energy, billed as "the world's first caffeine based topical energy spray" think there could be a market out there open to a new way of getting its fix.  Read More

Artist's conception of a commercial hydrogen production plant that uses sunlight to split ...

A new technique developed by a University of Colorado Boulder team converts sunshine and water directly into usable fuel. The technique involves concentrating sunlight in a solar tower to achieve temperatures high enough to drive chemical reactions that split water into its constituent oxygen and hydrogen molecules. In this way, the team says it should be able to cheaply produce massive amounts of hydrogen fuel.  Read More

Monash University researchers have created a compact electrode that uses a liquid electrol...

Graphene-based supercapacitors have already proven the equal of conventional supercapacitors – in the lab. But now researchers at Melbourne’s Monash University claim to have developed of a new scalable and cost-effective technique to engineer graphene-based supercapacitors that brings them a step closer to commercial development.  Read More
