‘Hot spots’ increase efficiency of solar desalination

Researchers showed they could boost the efficiency of their nanotechnology-enabled solar membrane desalination system by more than 50% simply by adding inexpensive plastic lenses to concentrate sunlight into ‘hot spots.’ Read Full Article Here For more great articles: Solar Energy News — ScienceDaily

Carbon-neutral fuel made from sunlight and air

Researchers have developed a novel technology that produces liquid hydrocarbon fuels exclusively from sunlight and air. For the first time worldwide they demonstrate the entire thermochemical process chain under real field conditions. Read Full Article Here For more great articles: Solar Energy News — ScienceDaily

Precision calibration empowers largest solar telescope

As with any astronomical instrument, calibration is required in order to remove effects that the instrument itself might have on the data. New research marks a substantial advance in ensuring the accurate solar information measured and collected by the Daniel K. Inouye Solar Telescope (DKIST).

A rose inspires smart way to collect and purify water

A new device for collecting and purifying water was inspired by a rose and, while more engineered than enchanted, is a dramatic improvement on current methods. Each flower-like structure costs less than 2 cents and can produce more than half a gallon of water per hour per square meter. Read Full Article Here For more…

Producing electricity at estuaries using light and osmosis

Researchers are working on a technology to exploit osmotic energy — a source of power that’s naturally available at estuaries, where fresh water comes into contact with seawater. In a laboratory experiment, the team reproduced the real-world conditions that occur where rivers meet the sea (pH and salt concentration) and showed that, by shining light…

Big energy savings for tiny machines

Physicists demonstrate for the first time a strategy for manipulating the trillions of tiny molecular nanomachines inside us that work to keep us alive, to maximize efficiency and conserve energy. The breakthrough could impact numerous fields, including creating more efficient computer chips and solar cells for energy generation. Read Full Article Here For more great…

Crowd oil: Fuels from air-conditioning systems

Researchers have proposed a method enabling air conditioning and ventilation systems to produce synthetic fuels from carbon dioxide (CO2) and water from the ambient air. Compact plants are to separate CO2 from the ambient air directly in buildings and produce synthetic hydrocarbons which can then be used as renewable synthetic oil. Read Full Article Here…
