Device Reduces Carbon Dioxide with Bacteria and Nanowires

Guest Contributor — Sun, 17 Jan 2016 17:20:20 +0000

A scientist from University of California, Berkeley, came up with a bright idea on carbon dioxide reduction by mimicking photosynthesis. This is in the person of Peidong Yang, a nanomaterials chemist, who focuses his study on a better approach of artificial photosynthesis in the lab. The process of photosynthesis is hard to imitate in the […]

Nanowire Solar Panel More Efficient at No Additional Cost

Benji Jerew — Tue, 09 Apr 2013 21:08:17 +0000

Solar installation prices continue to fall as solar panel manufacturers add to the glut of solar panels on the market already. The standard silicon-based solar panel is no more efficient than before, and there are just too many on the market to make a profit. Other technologies could make solar panels more efficient, but not […]

Solar Power Conversion Efficiency Limits Broken, Nanowires Win

Benji Jerew — Mon, 25 Mar 2013 19:19:57 +0000

With the development of nanotechnology, researchers using nanowires in solar cells are finding that solar cell efficiency limits may be higher than they previously thought possible. Current commercial silicon-based solar cell efficiency is less than 15%, which means that more than 85% of the sun’s energy is lost to heat and reflection. Modern theory places […]

Nanowire Technology Used for More Efficient Solar Cells

Benji Jerew — Tue, 22 Jan 2013 18:43:39 +0000

Silicon solar cells currently are, at a maximum, between 19% and 50% efficient converting solar energy into electricity. The rest of that energy is lost to heat and reflection, as well as resistance in the cells themselves. Part of the problem is that silicon solar cells can only be made reactive to a certain part […]

Geobacter Bacteria Cleaning up Nuclear Waste and Generating Electricity

Ovidiu Sandru — Mon, 12 Sep 2011 17:45:54 +0000

Some microbes may be able to clean up nuclear waste and at the same time generate electricity. Michigan State University (MSU) researchers have recently discovered how a bacterium called Geobacter can do all that. “Geobacter bacteria are tiny micro-organisms that can play a major role in cleaning up polluted sites around the world,” said Gemma […]
