Record-breaking solar flight reaches Hawaii after 5 nights and days airborne without fuel

Fri, 07/03/2015 - 2:59pm
The longest and most difficult leg of the Round the World Solar Flight attempted since last March by Swiss explorers Bertrand Piccard and André Borschberg ended successfully in Hawaii. At the controls of Solar Impulse 2, pilot André Borschberg landed safely in Hawaii after flying 117 hours and 52 minutes over the Pacific Ocean from Japan powered only by the sun.

Viaducts with wind turbines, the new renewable energy source

Thu, 07/02/2015 - 8:51am
Wind turbines could be installed under some of the biggest bridges on the road network to produce electricity. So it is confirmed by calculations carried out by a European researchers team, that have taken a viaduct in the Canary Islands as a reference. This concept could be applied in heavily built-up territories or natural areas with new constructions limitations.

New storage cell for solar energy storage, nighttime conversion

Wed, 07/01/2015 - 12:18pm
A materials science and engineering team has developed a new energy cell that can store large-scale solar energy even when it's dark.

New method can make cheaper solar energy storage

Wed, 07/01/2015 - 7:37am
Building on a unique idea, scientists have developed a cost-effective new method for converting and storing solar energy into hydrogen.

Orange is the new red

Sat, 06/27/2015 - 7:12am
A photoprotective mechanism in cyanobacteria is triggered by an unprecedented, large-scale movement from one location to another of the carotenoid pigment within the Orange Carotenoid Protein, researchers have discovered.

Better heat exchangers using garbage bags

Fri, 06/26/2015 - 12:07pm
Researchers are making better heat exchangers for industrial use using the same plastic as in garbage bags.

First certified efficiency of 15% in perovskite solar cells with area of over 1 square cm

Thu, 06/25/2015 - 7:13am
Researchers achieved 15% energy conversion efficiency in perovskite solar cells for the first time certified at an international public test center.

Distributed technique for power 'scheduling' advances smart grid concept

Wed, 06/24/2015 - 9:59am
A new technique for 'scheduling' energy in electric grids has been developed. It moves away from centralized management by tapping into the distributed computing power of energy devices. The approach advances the smart grid concept by coordinating the energy being produced and stored by both conventional and renewable sources.

Toward tiny, solar-powered sensors

Tue, 06/23/2015 - 12:19pm
Scientists have developed a new power converter chip that can harvest more than 80 percent of the energy trickling into it, even at the extremely low power levels characteristic of tiny solar cells. Previous experimental ultralow-power converters had efficiencies of only 40 or 50 percent.

Russia's renewable energy policy: Profitable for investors

Tue, 06/23/2015 - 6:29am
In 2013, Russia implemented an incentive system for renewable energy sources that is based on the wholesale electricity capacity mechanism. It is intended to increase the share of renewable energy in the country's energy production. New researchers demonstrates that the incentive system can make renewable energy investments in wind, solar and small-scale hydro power profitable for investors. However, in order to be profitable the investments must be within the scope of the full Russian support scheme.

Chemists devise technology that could transform solar energy storage

Fri, 06/19/2015 - 9:36am
Chemists have developed a major improvement to capture and retain energy from sunlight, where the stored energy can last dramatically longer than current solar technology allows -- up to several weeks, instead of the microseconds found in today's rooftop solar panels.

First solar cell made of highly ordered molecular frameworks

Fri, 06/19/2015 - 7:44am
Researchers have developed a material suited for photovoltaics. For the first time, a functioning organic solar cell consisting of a single component has been produced on the basis of metal-organic framework compounds (MOFs). The material is highly elastic and might also be used for the flexible coating of clothes and deformable components.

Highest certified efficiency for perovskite solar cells measuring over one square centimetre

Thu, 06/18/2015 - 2:05pm
Researchers have achieved a 15% energy conversion efficiency in perovskite solar cells for the first time in the world, as officially recognized by an international public test center.
