Ray Armstrong’s mountain home in Colorado Springs is a sprawling 5,500 square foot structure, with the living space extending outdoors where the owner’s fish ponds and water gardens are located. Armstrong is an award-winning koi fish enthusiast, and his home uses even more energy since the ponds and tanks, where his fish are, require precise temperature and water regulation. Since such a large home also consumes vast amounts of energy, Armstrong enlisted the help of David Bednarski, owner of Bestway Mechanical in Colorado Springs, to help him install the necessary solar and other technologies to reduce this footprint.
A group of researchers at the North Carolina State University (NCSU) have recently successfully developed solar cells that are able to heal themselves. More specifically, the scientists have successfully been able to solve the problem of dye-sensitized solar cells (DSSC), namely that the dyes used to create energy in these cells would eventually be destroyed by UV radiation.
DSSC cells contain a water-based gel core, electrodes, and inexpensive, light-sensitive, organic dye molecules that capture light and generate electric current. The original cells were created by mimicking the photosynthesis process that occurs in the leaves of plants. In trying to solve the problem of the dyes eventually becoming ineffective due to exposure to UV rays, the NCSU scientists again looked to plants for inspiration. The solar cells they developed contain a network of vascular channels that are very similar to the veins in a leaf, which are used to maintain water and nutrient levels throughout the leaf. The researches found that the needed dyes could be effectively delivered and replenished via this network. The dye that had been rendered ineffective by UV radiation can also be removed through this network.
On January 1, 2014 the federal ban on manufacturing 40- and 60-watt incandescent bulbs went into effect. One of the main implications of this ban is that consumers are slowly going to be forced to opt for LED or CFL light bulbs. However, the shape, cost and light quality of LED light bulbs has not made them very popular with consumers thus far. Philips aims to change that by releasing an innovative LED light bulb, which is called SlimStyle, retails for less than $10 and is flat.
