Getting Energy and Clean Water From the Clouds
A team of scientists is currently raising funds through a crowd funding campaign to develop Air HES (HydroElectric Station), which is basically an airship that can extract clean water and electricity from the clouds. More specifically, it does so by harvesting and condensing water vapor, and uses it to spin up an electric turbine generator…

Stacking Solar Cells Could Vastly Improve Their Efficiency
Harvesting solar energy is a great way to generate sustainable power, but unfortunately solar cells are far from being as efficient as they might be. Currently, commercially available solar cells can convert about 25 percent of sunlight into electricity, and scientists have been trying to create better solar cells for years. One milestone they have…

Listening to Plants
Photo: Video screen capture EuroNews Plants, just like humans and animals, have a way of communicating with each other. Their language is comprised of electrical signals, through which they send messages to other plants. And now an international group of scientists is developing a way to analyze these electrical signals, and translate them into information…

More Environmentally Friendly Solar Cells
Researchers at Northwestern University have developed a new solar cell that uses tin instead of lead perovskite as a collector of solar energy. This cheap and environmentally-friendly solar cell can therefore be made without any high-tech equipment or hazardous materials. The new solar cell developed by the team uses a structure called a perovskite and…

Could Tofu be the Answer to Greener Solar Cells?
University of Liverpool News Dr. Jon Major, a researcher at Liverpool University has recently made the discovery that the chemical used to make tofu, and bath salts, could also be used to replace one of the most toxic substances, namely cadmium chloride, that are used to manufacture solar cells. Using salts to replace cadmium chloride…
