Making universities obsolete Matt Welsh \| Jan 23, 2012 Sebastian Thrun recently announced that he was leaving Stanford to found a free, online university called Udacity. This is based on his experiences teaching the famous intro to AI class, for free, to 160,000 students online. Is this just Education for the Twitter Generation? Or truly a revolution in how we deliver higher education? Will this ultimately render universities obsolete? I want to ponder the failings of the conventional higher education model for a minute and see where this leads us, and consider whether something like Udacity is really the solution.

PUE Version 2 Improves Green Data Center Measurements Posted on January 18, 2012 by The Higher Ed CIO Image Courtesy of Mission Critical Magazine Power Usage Effectiveness (PUE) is the accepted metric for measuring and reporting data center energy performance. But with so much interest in green data centers in recent years there was a need to create greater consistency and clarity in how power usage effectiveness was measured and reported. Readers of this blog may recall earlier stories about the use of PUE, Green IT, and scorecards for Internet data centers and the difficulty in comparing one data center to another. To address the issues with PUE the Taskforce that gave us the original version of the PUE met again and in May of 2011 released “Recommendations For Measuring and Reporting Overall Data Center Efficiency Version 2 – Measuring PUE for Data Centers” ( Download PUE Version 2) clarifying the metric. PUE Version 2 does a couple of very important things. Article continues: blog.thehigheredcio.com ------

Opposing view: Why 3-D Printing Will Go the Way of Virtual Reality Extruding, printing, and sintering are not the same as manufacturing. 'The desire for 3-D printing to take over from traditional manufacturing needs to be recognized for what it is: an ideology. Getting all of our goods from a box in the corner of our home has attractive implications, from mass customization to " the end of consumerism." With stakes like those, who wouldn't want to be a true believer? Hype is inevitably followed by some level of backlash, or at least disinterest, and it would be a shame for 3-D printing to head into a too-deep trough of the Gartner hype cycle. There will be plenty of interesting applications for 3-D printing, but I'll bet the ones that will have the biggest impact will be within traditional factories, where rapid prototyping is already having a huge impact.' technologyreview.com Jim

What's Ahead for Natural Gas? By Amy Harder energy and environment reporter, National Journal What are the challenges and opportunities ahead for natural gas? The recent revolution involving shale natural gas in the United States has sparked debate on a range of issues: the environmental and safety concerns surrounding hydraulic fracturing--the controversial extraction method that's critical to accessing shale gas; how gas should be used within the country; and whether gas should be exported to countries where prices are high compared to domestic prices, which are at record lows. Recent developments on these issues underscore the importance of the natural-gas industry. More and more states are enacting laws that require companies to disclose the ingredients and concentrations of the fluids used in hydraulic fracturing. The Energy Department is already approving the first natural-gas exports, and several other applications are pending before it. Meanwhile, legislation in Congress would provide tax incentives for natural-gas-powered trucks, and Environmental Protection Agency clean-air rules are encouraging more utilities to shift from coal-fired power plants to natural gas, which burns cleaner than coal. How should President Obama and Congress handle these disparate issues in the natural-gas industry? Should Congress enact federal legislation requiring disclosure of fracking fluids? Should the United States export natural gas to capitalize on the shale gas revolution and high prices abroad? What role, if any, should the U.S. government play in regulating natural-gas exports? energy.nationaljournal.com

Regional Cap-and-Trade Effort Seeks Greater Impact by Cutting Carbon Allowances By MIREYA NAVARRO \| NY Times \| Jan 26, 2012 Adjusting to shifts in the economy, states in the cap-and-trade system known as the Regional Greenhouse Gas Initiative have slashed the number of allowances that electric power companies can buy to offset their emissions. The decision, made last week, was intended to shore up the pioneering program as it undergoes its first comprehensive review this year. While the program has been judged a success by most of the participating states, in the Northeast and Mid-Atlantic, an oversupply of the allowances — in essence, permits to pollute — has limited the program’s impact.

Everything You Know About Peak Oil Is Wrong We’re not running out of resources. Quite the contrary. And in our abundance lies a paradox Charles Kenny, New America Foundation businessweek.com <> In 1971, the Limits to Growth team forecast that the world’s supply would run out 10 years from today. And yet according to renowned oil analyst Daniel Yergin, technology advances and new discoveries have allowed oil reserves worldwide to keep growing. For every barrel of oil produced in the world from 2007 to 2009, 1.6 barrels of new reserves were added. The World Energy Council reports that global proven recoverable reserves of natural gas liquids and crude oil amounted to 1.2 trillion barrels in 2010. That’s enough to last another 38 years at current usage. Add in shale oil, and that’s an additional 4.8 trillion barrels, or a century and a half’s worth of supply at present usage rates. Tar sands, including some huge Canadian deposits, add perhaps 6 trillion barrels more.
