Researchers at the Georgia Institute of Technology have developed a new treatment for silicon photovoltaic solar cells that creates bumps and peaks on the surface that increase cell efficiency in two ways.
Researchers at Georgia Tech recently discovered that hamsters running on wheels are good for more than just a laugh— they can also drive nanogenerators to produce electric currents. While the electricity produced from hamster biomotions is small (one nanowatt), it may be enough to drive nano-sized devices.
There is a growing recognition that there are two convergent crises facing the world: energy and water. Scientific American launched a dedicated environmental publication this month, Earth 3.0, with the cover story Energy Vs Water. The article explores the dichotomy between the fact that we need energy to produce water … [continued]
Motorists are cruising around Atlanta or waiting in long lines looking for gasoline. Many fueling stations have run dry, while others have extremely long lines.

With my complete lack of faith in the US federal government, it warms my heart aplenty to see so much initiative by local governments and businesses in going green. On Friday of last week, the 19th, two announcements were made that saw plans revealed for two new renewable energy sources. … [continued]
Sunflowers are already used for oil production and to make biodiesel— now scientists want to look into their viability as ethanol producers in the state of Georgia and beyond. Over the next few years, University of Georgia scholar Steve Knapp will study silverleaf and Algodones dune sunflowers, both of which … [continued]
Big news for the wind industry, big implications for water. First, the Department of Energy released a report that confirmed what the wind industry has already claimed: wind could power 20% of the United State’s energy needs by 2030. Even with growing energy demands, our ample wind resources could meet … [continued]
There’s been a lot of focus on renewable energy on Cleantechnia recently but energy is not the only “clean” tech out there. What about recycling wastes? What about recycling… human wastes? What’s the difference between traditional wastewater treatment and sewage purification (also known as ‘indirect potable water reuse”)? Is it … [continued]
