Electricity use and efficiency of servers and data centers: A review of recen... Google Tech Talks December, 4 2007 The Internet economy depends on a reliable computing infrastructure. While earlier reports of information technology using vast amounts all electricity were grossly exaggerated, these facilities still use electricity, and this use is growing rapidly. Recent analysis indicates that data center electricity use in both the US and the world roughly doubled from 2000 to 2005, and this growth is expected to slow only modestly over the following five years. Growth of this magnitude represents a substantial business opportunity for technology companies. This talk will describe results of recent work analyzing trends in total data center power use and how this growth varies by major world region. It will also explore the misplaced incentives and institutional failures that impede data center efficiency investments on a large scale. Finally, it will describe business, government, and research efforts to improve efficiency in these mission critical facilities, including recent work by the Energy Star program to promote server and data center efficiency. Speaker: Jonathan Koomey Dr. Koomey held the MAP/Ming visiting professorship in energy and environment at Stanford University for the 2003-2004 school year, and is now a Consulting Professor at Stanford. He is also a Staff Scientist at Lawrence Berkeley National Laboratory (LBNL), in Berkeley, California. For more than eleven years he led the End-Use Forecasting group at LBNL, which analyzes markets for efficient products and technologies for improving the energy and environmental aspects of those products. The group develops recommendations for policymakers at the U.S. Environmental Protection Agency and the U.S. Department of Energy on ways to promote energy efficiency and prevent pollution. He's also a Research Affiliate of the Energy and Resources Group at the University of California, Berkeley. Tags: google techtalks techtalk engedu talk talks googletechtalks education |

Fallkniven A1: Compact Efficiency The A1 is just 14 oz but sports a nearly 1/4" thick blade. From my other "clinic" videos, I've demonstrated how such a thicker blade makes wilderness tasks easier, expending less energy. This is a huge advantage of this compact survival knife that few others possess. Other great features of the A1 include: laminated VG10 steel that will serve well in high moisture areas (and CeraCoated in black), a comfortable handle, full tang that can deliver defensive impacts, a convex grind, a good Kydex (now Zytel) sheath, and a reasonably price for such a high quality blade. This is the type of knife that disproves the oft-heard custom knife maker criticism that says production blades suck. A limitation of the design is its 6.3" blade which for me is on the short side for a wilderness blade. However often weight and size are very important and our system needs will prevent carrying a larger, heavier blade. In those situations this Fallkniven A1 is ideal and it will serve admirably as both a wilderness or tactical fixed blade. Improvements could include a quick detach method for the sheath, a longer handle (by just 1/2"), and maybe one day a full flat grind :-). Also please NOTE that I had reports on the brittleness of this laminated VG1 steel and ("mtbaddict" has his A1's tip break off) it seems you'll trade off some toughness for increased rust resistance. Still, the A1 is a capable blade and compact in dimensions, that can serve you well in the woods. SAFETY NOTE: These videos will show imperative common sense safety measures to keep YOU safe from your own blades (and falling timber). Accidentally cutting YOURSELF is the biggest danger you will face in the woods.

#134 - Generator HHO run time efficiency tests, Part 4 of 4 For latest news please visit my web site http://www.alt-nrg.org/ In this mini-series I attempt to answer the age old question posed by our critics "Are we on the right track or just spinning our wheels?" For this test I am using a gasoline powered AC generator. This is the ideal platform to test with because it's carbeureted. No fuel injection ECU, O2, MAF, etc to deal with. No EFIE required. ================================================= I have collected the data. You be the judge.
