Researchers at MIT have unveiled a new type of silicon solar cell that could be much more efficient and cost less than currently used solar cells. The design combines a highly effective reflector on the back of a solar cell with an antireflective coating on the front. This helps trap red and near-infrared light, which can be used to make electricity, in the silicon. The researchers applied their light-trapping scheme on thin silicon cells that are about five micrometers thick. Their prototype solar cell is 15 percent more efficient at converting light into electricity than commercial thin-film solar cells. Read More.

Also known as cogeneration, CHP is the simultaneous production of electricity and heat from a single fuel source such as natural gas, biomass, biogas, coal, waste heat, or oil. According to a report from the Oak Ridge National Laboratory, boosting the use of combined heat and power, or CHP, to 20 percent of generating capacity in the U.S. by 2030 would save 5.3 quadrillion British thermal units of fuel annually, the equivalent of nearly half the total energy currently consumed by U.S. households. The lab said there would also be a 60 percent reduction of the projected increase in carbon dioxide, the equivalent of taking 154 million cars off the road. Read More.

The first solar-powered car to travel around the world ended its journey at the U.N. climate talks, arriving with the message that clean technologies are available now to stop global warming."This is the first time in history that a solar-powered car has traveled all the way around the world without using a single drop of petrol," said Louis Palmer, the 36-year-old Swiss schoolteacher and adventurer who made the trip. The car, which runs noiselessly, can travel up to 55 mph and covers 185 miles on a fully charged battery. Read More.
What if your house could generate electricity from the noise of the cars on the road? Or if the waste heat generated by your air conditioner could help put a dent in that expensive summer electric bill? As the demand for cheaper and more renewable energy sources increases, piezoelectrics - a class of material that produces an electric potential when mechanically deformed - may hold the key to unlocking the energy flowing all around us. There are applications of this technology already in place - certain dance clubs in Europe utilize dance floors with piezoelectrics to help power the lights. What would really be useful to the consumer, however, would be small piezoelectric systems that could assist in powering personal electronic devices. Read More.
