China took a further step on Sunday toward ending its dependence on U.S. satellites to provide navigation and positioning services.
A rocket carrying the fifth of a planned array of 35 orbiters blasted off from the Xichang space launch center in Sichuan, southwest China, the official Xinhua news agency reported. Beijing started a drive to end its reliance on the U.S. Global Positioning System in 2000, when it sent an experimental pair of positioning satellites into orbit.
The mobile for the hard of hearing: ring tone is as loud as a vuvuzela

The Amplicom M6000 is ideal for the elderly or anyone with hearing loss as it comes equipped with a ring-tone that can blare out 100 decibels. It will not make you popular with the neighbors.
But if your hearing is not what it was and you do not always hear your mobile ring, it could be the phone for you.
With a ring tone that can reach 100 decibels, the same as a pneumatic drill, there is no chance that you'll miss it going off - and nor will anyone in your street. And for the hard of hearing, the earpiece can be set to an even higher volume - 110dB, the equivalent of a South African vuvuzela horn being blown at full blast beside your head.

The focusing apparatus - known as the concentrator – is key to CSP technology Concentrating solar power (CSP) is a thermal technology;
that is, it generates electricity by boiling water, then forcing the high-temperature, high-pressure steam through a series of turbines. In this sense, it is analogous to every baseline electricity generation technology. Rather than burning fossil fuel or tapping the heat of a nuclear reaction, it uses the heat of the sun as it hits the Earth’s surface.

Engineers today began the longest-ever test trip of driverless vehicles from Italy to China along the Silk Road, to examine the limits of future automotive technology. Two bright orange solar-powered electric vehicles will aim to cover 8,000 miles through the traffic of Moscow, the summer heat of Siberia and the bitter cold of the Gobi desert before the planned arrival in the World Fair in Shanghai at the end of October.

A giant 10MW offshore wind turbine that mimics a spinning sycamore leaf has been proposed by British company Wind Power Limited. The international architectural firm behind the Eden project, Grimshaw, has revealed the design of the massive machine, which will rotate on its axis and stretch approximately 275m from blade to tip. It is believed the first turbines will be built in 2013-14 following two years of testing.
