Wed, 17 May 2017 10:11:52 EDT
Scientists are building on the proven concept of autonomous cooperative soaring of unmanned aerial vehicles (UAVs), which enables long endurance flights of unmanned sailplanes that use the power of the Sun.
New, more efficient catalyst for water splitting
Mon, 15 May 2017 15:07:34 EDT
Physicists have discovered a catalyst that can split water into hydrogen and oxygen, composed of easily available, low-cost materials and operating far more efficiently than previous catalysts. That would solve one of the primary hurdles remaining in using water to produce hydrogen, one of the most promising sources of clean energy.
Key differences in solar wind models
Mon, 15 May 2017 12:59:39 EDT
The challenge of predicting space weather, which can cause issues with telecommunications and other satellite operations on Earth, requires a detailed understanding of the solar wind (a stream of charged particles released from the sun) and sophisticated computer simulations. New research has found that when choosing the right model to describe the solar wind, using the one that takes longer to calculate does not make it the most accurate.
Photovoltaics and batteries: An expensive combination
Mon, 15 May 2017 09:26:14 EDT
Solar power can cover up to 40% of the electricity needs of a typical household. Going beyond that level becomes really expensive: using batteries coupled with solar panels would be twice as expensive as using the power grid.
Data science used to better predict effect of weather and other conditions
Fri, 12 May 2017 19:57:38 EDT
Data science has been used by researchers to determine and predict the effects of exposure to weather and other conditions on materials in solar panels. Using data science to predict the deterioration of such materials could lead to finding new ways to extend their lifetime, the researchers say.
Next-gen solar cells could be improved by atomic-scale redesign
Fri, 12 May 2017 09:39:47 EDT

Power plants could cut a third of their emissions by using solar energy
Tue, 09 May 2017 08:38:29 EDT
The COMBO-CFB project has developed a new innovative concept to increase solar energy production in the energy system. According to this research, the concept can reduce fuel consumption and emissions stressing the climate by more than 33 per cent. The concept is based on the combination of concentrated solar power (CSP) technology and a traditional power plant process into a hybrid plant which produces electricity on the basis of consumption.
Installing solar to combat national security risks in the power grid
Mon, 08 May 2017 11:24:14 EDT
Power grid vulnerabilities are one of the most prevalent national security threats. The technical community calls for building up grid resiliency using distributed energy and microgrids for stabilization as multiple sources increases the difficulty of triggering cascading blackouts, and following an attack or natural disaster, microgrids can provide localized energy security. An interdisciplinary team calculated what it takes to make military bases more secure.
New technology generates power from polluted air
Mon, 08 May 2017 08:32:19 EDT
Researchers have succeeded in developing a process that purifies air and, at the same time, generates power. The device must only be exposed to light in order to function.
Photoluminescent display absorbs, converts light into energy
Tue, 02 May 2017 09:50:59 EDT
A new study demonstrates how to convert a luminescent solar concentrator into an energy-harvesting laser phosphor display by projecting intensity modulated light.
Solar cells with nanostripes
Tue, 02 May 2017 08:46:32 EDT
Solar cells based on perovskites reach high efficiencies: they convert more than 20 percent of the incident light directly into usable power. On their search for underlying physical mechanisms, researchers have now detected strips of nanostructures with alternating directions of polarization in the perovskite layers. These structures might serve as transport paths for charge carriers.
