Wind Could Provide 100% of World Energy Needs 867

Damien1972 sends in a report on a study published in the Proceedings of the National Academy of Science, which finds that wind power could provide for the entire world's current and future energy needs. "To estimate the earth's capacity for wind power, the researchers first sectioned the globe into areas of approximately 3,300 square kilometers (2,050 square miles) and surveyed local wind speeds every six hours. They imagined 2.5 megawatt turbines crisscrossing the terrestrial globe, excluding 'areas classified as forested, areas occupied by permanent snow or ice, areas covered by water, and areas identified as either developed or urban,' according to the paper. They also included the possibility of 3.6 megawatt offshore wind turbines, but restricted them to 50 nautical miles off the coast and to oceans depths less than 200 meters. Using [these] criteria the researchers found that wind energy could not only supply all of the world's energy requirements, but it could provide over forty times the world's current electrical consumption and over five times the global use of total energy needs."

Google's Floating Datahaven 450

PDG writes "Google has pending plans to take its data centers off-shore, literally. By moving their data centers to floating barges in international waters, they are able to save money on taxes and electricity (using wave based power) as well as reside their operations outside the jurisdiction of governments. There is mention of hurricane and other caveats, but I wonder how they plan to get a bandwidth pipe large enough and still be reliable. Seems like a chapter out of a Neal Stephenson novel." You might recall earlier discussions on the same subject.
