Located in Bern, Switzerland, the world’s largest solar stadium is operational. The stadium has a total of over 10,000 solar cells yielding in an overall output of 1.3 megawatts of power and expected to produce 1.134 gigawatts hours of electricity annually - the equivalence of 350 four-person households.

xxonMobil Chemical and ExxonMobil's Japanese affiliate, > Tonen Chemical > have developed a thin film separator for use in lithium-ion batteries, that would enable production of batteries like those found in cell phones and laptops, to power cars and trucks. These new film technologies are expected to significantly enhance the power, safety and reliability of lithium-ion batteries, thereby helping speed the adoption of these smaller and lighter batteries into the next wave of lower-emission vehicles. >

The pigments from dark-colored berries absorb sunlight extremely well. Since the extraction of the pigment is simple task, production of solar cells would increase. Unfortunately, efficiency rates are considerably lower

They have successfully created a solar coating that is the most cost-efficient solar energy source ever. Their PowerSheet cells contrast the current solar technology systems by reducing the cost of production from $3 a watt to a mere 30 cents per watt. This makes, for the first time in history, solar power cheaper than burning coal.

Almost one in five Europeans have cut off their landlines, relying entirely on cell phones and mobile device to make their calls. A recent Eurostat study included all 27 EU countries except Bulgaria and Romania.

alled the HB-SIA, the prototype aircraft consists of wing covered with solar cells with a span of 200 feet. Despite that huge wing span, the craft will employ lightweight materials to tip the scales at only 3,300 pounds. That combination will allow the plane to fly at just 28 miles per hour, a speed that will keep energy consumption low, allowing the solar panels to not only power the craft during the day, but to also store up enough energy to keep it flying at night. Construction of the HB-SIA began in June and is expected to be complete by the summer of 2008.
