Google puts money into cementing green energy standards in Asia

Plenty of big tech companies are looking to source green energy whenever they can for their substantial energy needs, and Google is the same. But it looks like it's hard to find the renewable energy you're looking for in Asia -- specifically China, w...

IBM manufactures light-based ‘nanophotonic’ chips to let the terabytes flow

IBM manufactures lightbased 'nanophotonic' chips to let the terrabytes flow

IBM's taken a large step toward computer chips that use photons instead of electrons by manufacturing the first 90nm silicon-based optical processing modules. It did so using the CMOS nanophotonics technology we first saw back in 2010, creating tranceivers capable of 25Gbps transfer speeds. By multiplexing a large number of those streams to a single fibre, "terrabytes of data" per second could flow between distant computer systems," according to IBM. The 90 nanometer light circuits should allow data-hungry servers or supercomputers to scale up rapidly in speed "for the next decade, and at the desired low cost," according to the researchers. It's now primed for commercial development, meaning we could see an end to bottlenecks in systems "a few centimeters or a few kilometers" apart from each other. Check the PR for the detailed technical skinny.

Researchers turn to 19th century math for wireless data center breakthrough

Researchers turn to 19th century math for wireless data center breakthrough

Researchers from Microsoft and Cornell University want to remove the tangles of cables from data centers. It's no small feat. With thousands of machines that need every bit of bandwidth available WiFi certainly isn't an option. To solve the issue, scientists are turning to two sources: the cutting edge of 60GHz networking and the 19th century mathematical theories of Arthur Cayley. Cayley's 1889 paper, On the Theory of Groups, was used to guide their method for connecting servers in the most efficient and fault tolerant way possible. The findings will be presented in a paper later this month, but it won't be clear how effectively this research can be applied to an actual data center until someone funds a prototype. The proposed Cayley data centers would rely on cylindrical server racks that have transceivers both inside and outside the tubes of machines, allowing them to pass data both among and between racks with (hopefully) minimal interference. Since the new design would do away with traditional network switches and cables, researchers believe they may eventually cost less than current designs and will draw less power. And will do so while still streaming data at 10 gigabits per second -- far faster than WiGig, which also makes use of 60GHz spectrum. To read the paper in its entirety check out the source.

Facebook releases its 2011 energy usage report, details your carbon footprint

Facebook releases its 2011 energy usage report, details your carbon footprint

More Facebook news, but this time we're back to the numbers instead of reporting on a new feature, improvement or integration. As part of its mission to swap the familiar blue for something of a greener tinge, Facebook released today its carbon footprint and overall energy usage figures for 2011. Turning bio-babble into easy visualizations, the company points out that for the whole year, an active user occupied roughly the same carbon footprint as one medium latte. Or, if you're a fan of the tipple, a couple of glasses of wine. Impressively, 23 percent of the social giant's energy usage came from clean and renewable sources, which puts it well on the way to its 2015 target of 25 percent or more. If you'd like more info and a complete breakdown of the stats, the full report is available at the source link below.

Apple breaks ground on second solar farm for North Carolina data center

Image

Last February, Apple came clean about its efforts to clean up the environment, detailing intentions to make its Maiden, NC data facility a greener place. That site, already home to one solar farm, is now set to host a second 20 megawatt photovoltaic array spanning 100 acres, a one-two power punch that'll jointly generate 84 million kWh annually. Combined with the company's in-development biofuel cell plant, scheduled for opening later this year, that theoretic yield should hit the 124 million kWh mark -- an amount sufficient to power nearly 11,000 households -- providing 60 percent of the center's electric demands. Still, that's not enough to adequately keep operations afloat, so for that very necessary, leftover 40 percent, the house that Jobs built plans to purchase similar clean energy from outside local sources. When all is finally up and running smoothly, the southern facility will earn the distinction of "most environmentally sound data center ever built." Or, at least until another well-heeled competitor comes along to contest that title. Now that's a friendly competition we can get behind.
