Telecom Forum / A smarter mirror for cheaper solar power
« on: April 10, 2012, 06:18:40 PM »
Rather than try to reinvent the solar cell, startup Thermata has engineered a high-tech mirror to cut the cost of solar power.
The company, incubated at Idealabs, has completed initial testing on a system executives say can cut the cost of sun-tracking mirrors, or heliostats, in half using cameras and other digital technologies. Thermata plans to start beta testing the heliostats this year with potential customers, which are concentrating solar power technology companies, and with Sandia National Laboratories.
Thermata typifies a new breed of green-technology startup which is targeting a specific niche in energy using technologies from other fields. Its system uses a camera to detect the angle of heliostats and a mesh network of microprocessors to position each mirror with the ideal tilt. In a concentrating solar power plant, thousands or even millions of heliostats concentrate light onto a tower to produce steam, which turns a turbine to generate electricity.
"Instead of using calculations and past knowledge to infer where the mirror is, we can physically measure the angle and control it explicitly," said CEO Terry Bailey. "We've use intelligence instead of steel."
Heliostats now used at concentrating solar power plants are heavy-duty pieces of equipment, mounted on pylons to withstand high winds and connected via wires to control their motion.

Telecom Forum / Samsung puts Youm brand on its flexible screens
« on: April 09, 2012, 05:28:34 PM »
Samsung has quietly bestowed a name to its flexible AMOLED technology, an indication that we may soon see it on retailer shelves.
Youm is the name chosen by the electronics giant for its thin, next-generation screens, which are so malleable they can be bent into a wave or arc. Samsung claims it is "unbreakable."

Scientists develop ultra-thin solar cells:
Austrian and Japanese researchers on Wednesday unveiled solar cells thinner than a thread of spider silk that are flexible enough to be wrapped around a single human hair.
The thin-film device, comprising electrodes on a plastic foil, is about 1.9 micro-metres thick, a tenth the size of the thinnest solar cells currently available, the researchers said.

Solar-Powered Keyboards:
If you have opted for a wireless keyboard you know the importance of rechargeable batteries and a wall charger. Although it is easier to charge the batteries after a while it becomes an annoyance to change them repeatedly. Now Logitech is coming out with a solar-powered keyboard that will be free of such hassles.

Telestroke the next best thing:"Providing stroke patients fast and seamless access to stroke services regardless of where one lives in Canada will save lives and reduce disability, says Heart and Stroke Foundation spokesperson Dr. Michael Hill. Telestroke is another way that technology allows for an easy, cost-effective way to bridge geographic barriers to smoothly link stroke specialists with communities where on- site stroke care does not exist."
