China to Build a Zero-Carbon Green City

Tuesday, August 12th, 2008
gormanw writes "Just outside Shanghai, there is an island about the size of Manhattan. China is going to build its first-ever 'green city', complete with no gasoline/diesel powered vehicles, 100% renewable energy, green roofs, and recycling everything. The city is called Dongtan and it should house about 5,000 people by the end of 2010, with estimates of 500,000 by 2050. The goal is to build a livable city that is energy efficient, non-polluting, and protects the wildlife in the area."

New Map of Carved Up Arctic

Friday, August 8th, 2008
thepacketmaster writes "The International Boundaries Research Unit has recently published a new jurisdictional map of the Arctic, using geographic and legal definitions. Now it appears Santa Claus could potentially be Danish. But as pointed out in an article at The Star, more important than St. Nick is 'an area thought to contain one-fifth of the world's undiscovered and recoverable oil and gas resources,' and from this map, Russia has a huge claim in that."

Thirst For Coltan Fueling African Conflict

Friday, July 25th, 2008
MetaPhyzx writes "According to an article put forth by the Toward Freedom website, the metallic ore known as columbite-tantalite or coltan for short is fueling conflict in central Africa. The relevance to us who read news for geeks: Coltan is in quite a few consumer electronics; the article references the Sony Playstation series."

Robocars As the Best Way Geeks Can Save the Planet

Friday, July 25th, 2008
Brad Templeton writes "I (whom you may know as EFF Chairman, founder of early dot-com Clari.Net and rec.humor.funny) have just released a new series of futurist essays on the amazing future of robot cars, coming to us thanks to the DARPA Grand Challenges. The computer driver is just the beginning — the essays detail how robocars can enable the cheap electric car, save millions of lives and trillions of dollars, and are the most compelling thing computer geeks can work on to save the planet. Because robocars can refuel, park and deliver themselves, and not simply be chauffeurs, they end up changing not just cars but cities, industries, energy, and — by removing dependence on foreign oil — even wars. I, for one, welcome our new robot overlords." (More below.)

Home-Based Hydrogen Refueling Station

Thursday, July 10th, 2008
Sportsqs writes "One of the main barriers to the widespread adoption of fuel cell vehicles has been the lack of an adequate hydrogen-refueling infrastructure. Beyond a handful of hydrogen stations, such as the one near Los Angeles International Airport, there just isn't anywhere to fill up. Step forward ITM Power, a UK company that has developed a hydrogen refueling station that could be installed at home, providing a ready-made solution for fuel-cell car owners."

Cheaper Energy From Caverns of Compressed Air

Thursday, July 3rd, 2008
An anonymous reader writes "By using the Earth's vast underground caverns to store compressed air generated by wind farms at night, several U.S. municipalities will be "going green" by using that stored energy to generate daytime electricity on the cheap. Engineers at a National Lab think compressed air stored in underground caverns could cut in half the cost of electricity."

Building the Green Data Center

Saturday, June 21st, 2008
blackbearnh writes "O'Reilly News talked to Bill Coleman, former founder of BEA and current founder and CEO of Cassett Corporation, about the challenges involved in building more energy-efficient data centers. Coleman's company is trying to change the way resources in the data center are used, by more efficiently leveraging virtualization to utilize servers to a higher degree. In the interview, Coleman touches on this topic, but spends most of his time discussing how modern data centers grossly overcool and overdeploy hardware, leading to abysmal levels of efficiency."

Round Robin Scheduling Not Power-Efficient

Friday, May 9th, 2008
Via_Patrino writes "While having to distribute load between several servers, round robin, or any other technique that balances load equally, is the most common approach because of its simplicity. But a recent study shows that trying to accumulate load on some servers can improve energy efficiency because the other servers will be mostly unused during off-peak periods and then able to make better use of power saving methods. Specially, where load involves lots of concurrent power-consuming TCP connections, which was the case in the study, a new load-balancing algorithm resulted in an overall 30% power savings. Here's the paper (PDF)."

Data Centers Expected to Pollute More Than Airlines by 2020

Sunday, May 4th, 2008
Dionysius, God of Wine and Leaf, writes with a link to a New York Times story on a source of pollution that doesn't leave contrails: "The world's data centers are projected to surpass the airline industry as a greenhouse gas polluter by 2020, according to a new study by McKinsey & Co. ... [C]omputer servers are used at only 6 percent of their capacity on average, while data center facilities as a whole are used at 56 percent of peak performance." Data centers, though, might have more options for going green than airlines do, given present technology.

Tech That Will Save Our Species - Solar Thermal Power

Tuesday, April 15th, 2008
NoMoreCoal writes "Salon has up a story by Joe Romm, former undersecretary of energy during the Clinton administration, discussing a lesser-known alternative energy solution. It's a technology that (he claims) is ready to provide zero-carbon electric power big, fast, cheap and (most importantly) right now: solar thermal power. 'Improvements in manufacturing and design, along with the possibility of higher temperature operation, could easily bring the price down to 6 to 8 cents per kilowatt hour. CSP makes use of the most abundant and free fuel there is, sunlight, and key countries have a vast resource. Solar thermal plants covering the equivalent of a 92-by-92-mile square grid in the Southwest could generate electricity for the entire United States. Mexico has an equally enormous solar resource. China, India, southern Europe, North Africa, the Middle East and Australia also have huge resources.'" Interesting stuff, even if he does mention the Archimedes Death Ray.
