Researchers harness sun's energy during day for use at night

Solar energy has long been used as a clean alternative to fossil fuels such as coal and oil, but it could only be harnessed during the day when the sun's rays were strongest. Now researchers led by Tom Meyer at the Energy ...

Nanoparticle opens the door to clean-energy alternatives

(Phys.org) —Cheaper clean-energy technologies could be made possible thanks to a new discovery. Research team members led by Raymond Schaak, a professor of chemistry at Penn State University, have found that an important ...

First algae powered building goes up in Hamburg

(Phys.org) —A 15-unit apartment building has been constructed in the German city of Hamburg that has 129 algae filled louvered tanks hanging over the exterior of the south-east and south-west sides of the building—making ...

Scientists develop solar-to-fuel roadmap for crystalline silicon

Bringing the concept of an "artificial leaf" closer to reality, a team of researchers at MIT has published a detailed analysis of all the factors that could limit the efficiency of such a system. The new analysis lays out ...

New twist on old chemical process could boost energy efficiency

Chemical reactions on the surface of metal oxides, such as titanium dioxide and zinc oxide, are important for applications such as solar cells that convert the sun's energy to electricity. Now University of Washington scientists ...
