A cool idea; Electricity-free air conditioning
November 29, 2014
New materials may change the way temperatures are regulated AIR conditioning is a transformative technology. It has made the world's torrid climes pleasanter to live in, and enabled the siesta-free working habits of the temperate regions to move closer to the equator. But cooling buildings takes a lot of energy. Heat must be pumped actively from their interiors to their exteriors. Fully 15% of the electricity used by buildings in the United States is devoted to this task. If an idea dreamed up by Aaswath Raman of Stanford University and his colleagues comes to fruition, that may change. Dr Raman has invented a way to encourage buildings to dump their heat without the need for pumps and compressors. Instead, they simply radiate it into outer space. The idea, described in this week's Nature, is both cunning and simple. Outer space is very cold (about 3°C above absolute zero) and very big, so it is the perfect heat sink. Earth radiates heat into it all the time. But this is compensated for by the heat the planet receives from the sun. To encourage one part of Earth's surface (such as an individual building) to cool down, all you need do in principle is reflect the sunlight which falls on it back into space, while also encouraging as much radiative cooling from it as possible.

US court turns down Motorola's price-fixing appeal

U.S. court rejects Motorola Mobility price-fixing appeal
November 27, 2014
- A federal appeals court rejected Motorola Mobility LLC's bid to sue several Asian suppliers under U.S. antitrust law for fixing prices of mobile phone displays sold to its foreign units. Wednesday's decision by the 7th U.S. Circuit Court of Appeals in Chicago may lessen protections against inflated prices for U.S. consumers who buy cellphones, computers and other products whose components are made outside the country.

ExtremeTech's 2014 holiday gift guide: High tech futuristic gift ideas for geeks and nerds
November 26, 2014
My fellow festive friends, writing for ExtremeTech is probably as close as we'll ever get to having an actual time machine. We write about science and technology that is so brazenly (and often bizarrely) futuristic that it's sometimes a bit of a shock to come back down to reality, to 2014, and find that I still don't have a Star Trek-like replicator in the kitchen or an implant that interfaces my brain to the world wide web. To soften that sad feeling of incessant contemporaneity - that feeling that our mundane lives could be just a little bit better with a sprinkling of futuristic tech - those of us here at ExtremeTech have now started to fill our homes, offices, and cars with high-tech gadgets and gizmos that feel like they're from the future. Now, with Christmas, Hanukkah, and the wonderfully generic holiday season fast approaching, we want to share those gadgets and gizmos with you. If you know someone who's a bit nerdy, or who's always complaining about how slow or boring or difficult real life can be, then I guarantee that our list is exactly what you need to read before heading out into the Black Friday or Cyber Monday morass.

New market study "Global Gallium arsenide (GaAs) Devices Market 2014-2018" has been published
November 26, 2014
GaAs is a crystalline compound composed of two elements gallium and arsenic. It is generally referred to as an III-V semiconductor and is used in devices such as microwave frequency integrated circuits monolithic microwave integrated circuits infrared light-emitting diodes laser diodes solar cells and optical windows. GaAs is increasingly being used as a replacement for silicon because of its enhanced electronic properties. For instance GaAs has high saturated electron velocity and electron mobility which allows the device in which it is used to function efficiently at frequencies above 250 GHz. Moreover as a result of the wider band gap GaAs devices are less sensitive to heat compared to silicon-based devices. In addition GaAs devices emit less noise than silicon devices especially at higher frequencies. As a result of these properties GaAs devices are used in cellphones satellite communication equipment microwave point-to-point links and high-frequency radar systems. Full Report Details atnbsp;-http://www.fastmr.com/prod/903217_global_gallium_arsenide_gaas_devices_market.aspx?afid=101TechNavio#39;s analysts forecast the Global GaAs Devices market to grow at a CAGR of 3.32 percent over the period 2013-2018. Covered in this Report This report covers the present scenario and the growth prospects of the Global GaAs Devices market for the period 2014-2018. To calculate the market size the report considers the revenue generated from the sales of GaAs devices worldwide.
