Indian man single-handedly plants a 1,360-acre forest A little more than 30 years ago, a teenager named Jadav "Molai" Payeng began burying seeds along a barren sandbar near his birthplace in northern India's Assam region to grow a refuge for wildlife. Not long after, he decided to dedicate his life to this endeavor, so he moved to the site so he could work full-time creating a lush new forest ecosystem. Incredibly, the spot today hosts a sprawling 1,360 acres of jungle that Payeng planted — single-handedly. 8 Completely Awesome DIY Home Energy Projects Small-scale renewable energy is a must for a sustainable home – but converting your home to clean energy options can carry a huge initial price tag. We’ve scoured the web for some of the most innovative examples of homemade energy solutions to compile a collective list of DIY projects to make your home greener and more energy efficient without costing you a fortune. From solar water heaters and gadget chargers to homemade super-efficient refrigerators, you’ll find links (with instructions) to some of the best projects you can make at home…
Hybrid nanomaterial converts light and heat into electricity A hybrid nanomaterial synthesized by combining copper sulfide nanoparticles and SWNTs can convert light and heat into electricity (Photo: Shutterstock) We’ve seen nanomaterials that can be used to convert light into electricity and others that can convert heat into electricity. Now researchers from the University of Texas at Arlington and Louisana Tech University have created a hybrid nanomaterial that can do both. By pairing the material with microchips, the researchers say it could be used in self-powered sensors, low-power electronic devices, and biomedical implants. While single-walled carbon nanotubes (SWNTs) have been used in the construction of transparent solar cells and all-carbon solar cells, these are still very inefficient when compared to their conventional photovoltaic brethren.

Compressed Air Energy Storage from LightSail Could Run a Whole City Clean Power Published on November 10th, 2012 | by Tina Casey The company LightSail Energy started out a few years ago with a student’s modest idea for a compressed air scooter, and now it has just raised $37.3 million in private funding to bring utility scale, compressed air energy storage to the market.
Intermittent energy source An intermittent energy source is any source of energy that is not continuously available due to some factor outside direct control. The intermittent source may be quite predictable, for example, tidal power, but cannot be dispatched to meet the demand of a power system. Effective use of intermittent sources in an electric power grid usually relies on using the intermittent sources to displace fuel that would otherwise be consumed by non-renewable power stations, or by storing energy in the form of renewable pumped storage, compressed air or ice, for use when needed, or as electrode heating for district heating schemes. The use of small amounts of intermittent power has little effect on grid operations. Using larger amounts of intermittent power may require upgrades or even a redesign of the grid infrastructure.

OverviewSentinel Mission The spacecraft and instrument use high-heritage flight proven deep space systems, originally developed by NASA, to minimize technical and programmatic risks. These heritage missions include large space-based telescopes (Spitzer, Kepler), a large format camera made up of many individual detectors (Kepler), and a cryogenically cooled instrument (Spitzer). By detective and tracking nearly all of the Near Earth Objects greater than 50 meters in diameter, the Sentinel Space Telescope will create a map of the solar system in Earth’s neighborhood enabling future robotic and manned exploration. The data provided by Sentinel will also identify objects that are potentially hazardous to humans to provide an early warning to protect the Earth from impact.

Clean storage: These scientists are making an organic, water-based battery for the power grid Most batteries — whether they’re embedded in your iPhone or they’re plugged into the power grid somewhere — use some kind of metal to create the chemical reaction that stores the energy. In laptops and Teslas, that metal is lithium; in traditional cars it’s lead. But researchers at University of Southern California are developing an all-organic, water-based battery that can be entirely synthesized (not using materials mined from the earth) and uses no metals or toxic chemicals.
