Siemens Turbine Blade
Siemens has released a series of images to show off its new B75 wind turbine rotor blades, and you really need to see them if you want to believe how big is big, at least when it comes to wind turbines. Each of the three blades, which measure a staggering 246 feet in length, is a single component made from epoxy resin and balsa reinforced with glass fiber. Compare that to an Airbus A380′s wings, which measure approximately 253 feet… continue…

Double-Sided Solar Cells Boost Energy Output

Posted In Living in Tech
Israeli startup bSolar has announced the creation of double-sided solar cells, which aim to produce up to 50 percent more electricity than traditional one-sided panels. The company’s photovoltaic cells get a boost in their efficiency by taking the unusual step of using boron instead of an aluminum backing, the company’s co-founder and CEO Yossi Kofman tells GigaOM. By using the boron’s black surface field, bSolar created an open rear face. That allows sunlight to be reflected back onto the front of the… continue…

eBay Plans a Green Data Center in Utah

This week saw a fun juxtaposition of power-related stories. First, there was an Amazon Web Services outage. It started with a power failure. Then the backup power failed. Then, the secondary backup power failed. Result: a few hours of downtime. Then, eBay announced that they were building a data center in Utah that will run off the power grid. Said John Donahue, eBay’s CEO: We are embracing disruptive energy technology and designing it into our core data center energy architecture. Running… continue…

Eole Water’s New Wind Turbine Produces Water, Electricity

eolewater
Eole Water’s newest development may help in the ongoing challenge of providing the poorest regions on Earth with clean drinking water and electricity. Its new type of wind turbine can produce both. Eole Water’s WMS1000 wind turbine combines a humidity condenser with a wind generator to produce both energy and water. With as little as 15 mph of wind it is able to harvest between 500 and 1000 liters of clean, drinkable water from the air, while generating 30 kilowatts… continue…

Suntech, Researchers Boost Solar Cell Efficiency

Solar House
Suntech Power Holdings and a team of scientists at Australia’s Swinburne University of Technology claim to have developed the world’s most efficient broadband nanoplasmonic solar cells. The team’s technology improved on existing thin-film solar cells by the incorporation of “bumpy” gold and silver nanoparticles. Thus far, the results seem impressive, as the researchers are claiming to have boosted the efficiency of thin-film solar cells to 8.1%. Gold and silver nanoparticles improve the efficiency of the solar cells because they are highly… continue…
