Sweden has a problem we all wish we had: not enough trash

Today, generating waste is almost unavoidable. Plastic packaging envelops everything we buy – even produce! The U.S. produces millions of tons of trash each year, of which more than half is sent to a landfill. As waste piles up in landfills,…

Super-Efficient Solar Water Desalination

A novel approach to desalinating water could be very beneficial in providing fresh water for many parts of the world needing clean water.  This is a relatively inexpensive process which uses graphite to use solar energy far more efficiently than ever before. Desalination is an important way to provide fresh water in many parts of the world, but it is usually an extremely energy intensive process.  In order to produce fresh water, the brackish water must be heated to produce steam, which leaves the salts behind.  Then, the steam is condensed to yield clean water. Solar power would seem to be ideal for this application, but, until now, it has required intense concentration of sunlight in order to produce the heat needed to boil the water. The method developed by Dr. Hadi Ghasemi at the University of Houston first microwaves graphite for a few seconds, causing it to fracture and pop “like popcorn.”  This material floats on top of a container of water and draws small amounts of water up through capillary action.  The pores in the material serve to further concentrate solar energy on those small amounts of water, causing it to steam.  Since the solar energy is concentrated on just the top layer, the rest of the water stays cool, so far less energy is needed to produce the steam. This allows cheaper and simpler equipment to be used to concentrate the solar energy and makes for a simpler system to produce clean water.  And graphite is a cheap and plentiful material, which also makes this a promising technology. via: BoingBoing and NPR

Nobel Prize Awarded for Blue LEDs

The Nobel Prize in physics this year has been awarded to three scientists, Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura, for their work in the development of the blue LED. LEDs were first developed in the early 20th Century, and the first practical, commercial LEDs were brought to the market in the 1960s.  However, the earliest LEDs were red or orange.  The development of blue LEDs was crucial to the ability to make “white light” LEDs, which combine blue, green, and red (or sometimes blue and yellow) to create an acceptable light source for general illumination.  The high efficiency of LED light bulbs and LED displays which we enjoy today stems from this research work. As the Nobel committee noted, “As about one fourth of world electricity consumption is used for lighting purposes, the LEDs contribute to saving the Earth’s resources.”  With the increased use of LEDs for lighting, demand for electricity is reduced.  We salute these three as EcoGeeks of the highest order. link: Nobel Foundation Press Release image: CC BY-SA 3.0 by Gussisaurio/Wikimedia Commons
