Researchers design a solar powered water filtration system, LDK Solar’s capacity reaches 3,000-MW and why MidAmerica’s purchase of Siemens wind turbines matters.
Researchers Design Solar Powered Water Filtration System
Safe drinking water is not something to be taken for granted for billions of people around the world. Designers have been innovating new systems that can improve the quality of drinking water for the least cost. Mostafa Bonakdar’s conceptual water dispensing unit can collect and purify rainwater for consumption. The “Hydroleaf” uses solar energy for its filtration process. Bonakdar claims the device can store 60 liters of water in its tank. Also, the Hydroleaf can function as storing device for renewable solar power that can be used to power a set of lights.
LDK Solar’s capacity reaches 3,000-MW
Leading multicrystalline solar wafer manufacturer, LDK Solar Company Ltd., has reached a new milestone in their production. The company announced a capacity of 3.0-gigawatts per year at its wafer plants. LDK is the world’s largest producer of multicrystalline wafers. LDK Solar also manufactures polysilicon, mono and multicrystalline ingots, wafers, modules and cells. “As the world’s leading wafer company, we are pleased to achieve this milestone,” stated Xiaofeng Peng, Chairman and CEO of LDK Solar. “This achievement positions the Company to continue to capitalize on the demand for its PV products.”
Siemens recently received its largest onshore wind turbine order for 258 units of its SWT-2.3-101model. The turbines are to be installed at three MidAmerican Energy Company wind projects that aimto provide 593-MW capacity for their Laurel, Rolling Hills and Pomeroy wind projects in Iowa. To date, Siemens Energy provides power systems that generate one-third of the electricity used in the country.Revenue from the company’s environment portfolio totaled 28 billion Euros, making Siemens theworld’s largest supplier of environmentally friendly technology.
Ormat Nevada Retracts DOE Loan Bid
Ormat Nevada Inc. has announced that it will look into financing its current geothermal projects through commercial investors, rather than federal support from the Department of Energy. The geothermal projects involved are Wister, CD-4 and Dead Horse Wells under construction in California and Nevada. They retracted their bid in cooperation with the John Hancock Life Insurance Company. Both parties agreed that the permitting process and transaction costs associated with the program may not work in their favor. Under the guidelines of the American Recovery and Reinvestment Act, projects that receive funding must have all permits necessary by September 2011. On the other hand, Ormat still expects to secure finances for the Jersey Valley, McGinness Hills and Tuscarora projects from the DOE before the program expires. Ormat also invested in the Oregon geothermal industry.
SunEdison Took Final Payment for Rovigo Power Plant
SunEdison has received its final payment of 230 million Euros for the sale of a 70-MW photovoltaic power plant near Rovigo, Italy. The power plant was bought by First Reserve and then built as a joint venture between the two companies. First Reserve made its first payment in October 2010, and now completed the purchase with the final 230 million Euros. “The development and sale of the Rovigo power plant was a major achievement and defining moment for SunEdison in 2010,” stated Carlos Domenech, President of SunEdison. “In less than ten months, we designed and developed one of the largest single operating solar power plants in Europe.” The plant is expected to power over 16,000 homes in the area, eliminating the emission of 40,000 tons of CO2 from the atmosphere.
Solar Powered Headphones
An industrial designer has created a concept pair of headphones that double as portable speakers. The device is powered by photovoltaic panels that recharge the headset’s battery. The device, called Hexound, is a portable wireless headset that features three removable units. The band can be removed so that it can be placed in the sunlight for a charge or even connected to a USB on rainy days. The two earphones can also function as removable speakers, allowing everyone to enjoy the music.
