Green IT

Researchers at Purdue University have had a breakthrough that may completely change how engineers design cooling systems in everything from computers to electric and hybrid cars.

Using special computer chips from Delphi Electronics, Suresh Garimella, the R. Eugene and Susie E. Goodson Professor of Mechanical Engineering at Purdue University, and doctoral student Tannaz Harirchia, have developed and tested new mathematical formulas concerning the properties of boiling liquids in "microchannels."

It's no secret that engineers, particularly chipmakers and computer manufacturers, have been striving for years to design cooling systems with highly efficient heat-transfer rates.

Microchannels are tiny channels … Read more

SOUTHBURY, Conn.--IBM's "green" data center here is kind of like a techie version of the "This Old House" television show. But in this case, the project was to build a showcase for energy-efficiency computing, rather than construct a new addition for a suburban home.

IBM's main problem was data center sprawl. Five years ago, internal IT staff could barely keep up with growing demand for computing resources from employees, causing an expansion from one data center location to four--a situation that was costly and inefficient.

Now, those four data centers have been consolidated … Read more

Please raise your hand if you've spent a lot of time in a basement environment while attempting to master one computer-related art or another.

I'm referring to any room with a noisy ventilation system, windows that don't open, and dim fluorescents overhead. You know the one. It was either so sweltering that you ended up wearing shorts in January, or kept so cold for the sake of the servers that you wore a scarf and fingerless gloves year-round.

Well, that universal rite of passage for computer lovers seems to be over for Carnegie Mellon University students thanks … Read more

Making data centers more energy efficient has been elevated to a college degree.

IBM on Wednesday said it has developed a two-year associates degree in "green data center management" in collaboration with the Metropolitan Community College in Omaha, Neb.

Starting in December, students will learn how to design and manage data centers to run efficiently in what IBM says is the first college degree in the subject. Classes will be offered online to remote students as well.

The Environmental Protection Agency in 2007 estimated that data centers alone use about 1.5 percent of all electricity in the … Read more

The University of Mississippi is letting the world in to observe its power consumption in real time.

As part of a green initiative guided by its Office of Campus Sustainability, the university is installing SmartSynch's SmartMeters to monitor and transmit data on the power consumption of lights, appliances, computers, and climate control systems in its buildings.

The SmartMeters contain software and hardware that give electrical meters their own Internet Protocol (IP) address and communicate data via the types of wireless networks used for cell phones back to a centralized virtual dashboard that can be accessed by utilities or customers.… Read more

The Green Electronics Council said Monday it is making its EPEAT rating system, now mandated in U.S. government agencies, available for computer gear sold in other countries.

Products certified by EPEAT--which stands for Electronic Product Environmental Assessment Tool--are listed in a registry. Products are judged on 23 attributes that make up an environmental performance rating. There are 28 optional attributes as well.

The ratings--either gold, silver, or bronze--cover monitors and desktop computers right now. The organization, which is made up of manufacturers, recyclers, and advocacy groups, is in the process of establishing an EPEAT rating for televisions, printers, and copiers. … Read more

If you plan on walking through the desert with a cell phone anytime soon, you might want to check in with Sanyo before you leave.

Its new Eneloop Portable Solar panels can charge portable devices through a USB connection. They're also relatively compact and a cinch to tote.

Sanyo's stylish Eneloop line of energy products includes a popular brand of rechargeable batteries and a lamp that doubles as a flashlight. Last time we posted about Sanyo's solar panels, they were chic but clunky. The new book-size, business-slick Portable Solar comes in sets of one or two panels (… Read more

Clean-technology investing could be seeing a rebound.

Cleantech Group, a research firm backed by Deloitte, released a preliminary report on Thursday showing a slight uptick in clean-tech funding during the second quarter of 2009 in North America, Europe, China, and India.

After two quarterly declines, the increase is good news, but the Cleantech Group noted that the quarter-to-quarter comparison for the same period a year ago is still down.

"The (second-quarter) total is up 12 percent from the previous quarter, although down 44 percent from the same period a year ago. The average round size in (the quarter) was $… Read more

Microsoft's move into the energy monitoring business may sound like a stretch, but to Craig Mundie, it's one of several natural new businesses for the software maker.

Mundie, Microsoft's chief research and strategy officer, said the company has its eye on any area that can be helped by technology and in which society is spending a lot of money and not seeing the return it would like.

Energy consumption specifically, and environmental issues more broadly, were natural areas for the company to delve into, he said, and follow Microsoft's moves into other thorny challenges such as … Read more
