Then you marry debian's apt-get to solaris' zfs file-system! What you get is Nexenta Core Platform OS. Let's take Nexenta for a quick spin, installing and configuring this young but promising system"

New Generator Boosts Wind Turbine Efficiency 50% 315

Posted by kdawson on Tuesday November 18, 2008 @03:30PM from the reap-the-whirlwind dept.

MagnetDroid writes "A startup company based in Vancouver has developed a new kind of generator that could harvest much more energy from the wind. The design could not only lower the cost of wind turbines but increase their power output by 50 percent to as much as 100 percent, in some locations. Normally, when wind speeds drop, a turbine's engine becomes less efficient. The new engine, from ExRo Technologies, runs efficiently over a wider range of conditions. The design replaces a mechanical transmission with what amounts to an electronic one. Magnets attached to a rotating shaft create a current, but individual coils can be turned on and off electronically at different wind speeds." The company will begin field-testing a small, 5KW wind turbine by early next year.

The latest theory of the Siberia 1908 explosion is that the body was so small that it disintegrated/vaporized before it hit the ground. It caused a shock/heat wave that caused severe destruction, but the area directly below the impact site was less damaged than the surrounding areas. I don't have an explanation of where the matter goes, maybe it gets driven into the ground and covered up over time by forces of nature. I'm thinking that there is a lot of heat and energy that plays a factor, but I don't know of what evidence remains, so I can't really speculate. --Dan
