UAE desert sand can store solar energy up to 1000°c
Researchers have successfully demonstrated that desert sand from the UAE could be used in concentrated solar power (CSP) facilities to store thermal energy up to 1000°C. The research project called ‘Sandstock’ has been seeking to develop a sustainable and low-cost gravity-fed solar receiver and storage system, using sand particles as the heat collector, heat transfer and thermal energy storage media.

Technology makes metal wires on solar cells nearly invisible to light
Scientists have discovered how to make the electrical wiring on top of solar cells nearly invisible to incoming light. The new design, which uses silicon nanopillars to hide the wires, could dramatically boost solar-cell efficiency.

Microbes map path toward renewable energy future
In the quest for renewable fuels, scientists are taking lessons from a humble bacterium that fills our oceans and covers moist surfaces the world over. Cyanothece 51142, a type of bacteria also called blue-green algae, produces hydrogen in robust fashion, and scientists have found that it taps into an unexpected source of energy to do so.
Electric mobility contributes decisively to climate protection
The transportation sector has the capacity to nearly halve its carbon dioxide emissions by 2050 and, hence, to contribute far more than previously thought to mitigate greenhouse gas emissions. Realizing this would require further efficiency improvement and, especially, promotion of public transport in cities, alongside with a large-scale shift to electric cars, concludes a recent study.

Better catalysts for green energy
A detailed account has been provided by researchers of how to control the electron charge of nanoparticles of platinum, an important catalyst in fuel cells, to maximize the efficiency of the process.
My city banned plastic bags — now where am I supposed to recycle them?
Q. Dear Umbra, Olympia recently banned plastic bags, which is great. Here is my problem: Now that stores are not using plastic bags, they have removed all the plastic bag recycle bins. I looked up places to recycle plastic bags in my area, and Lowe’s was listed. I took the bags I had been saving for six months to Lowe’s and they informed me that they would take the bags, but they are not recycled. The plastic bags just are thrown in their garbage. So I am back at the beginning again, trying to find somewhere to recycle the plastic bags that I have saved. Can you help me find somewhere that I could send these formerly recyclable plastic bags? Brooke W. Olympia, Wash. A…
