12 Small Windmills Put To the Test In Holland 510

tuna writes "A real-world test by the Dutch province of Zeeland (a very windy place) demonstrates that small windmills are a fundamentally flawed technology (PDF of tests results in Dutch, English summary). Twelve much-hyped micro wind turbines were placed in a row on an open plain. Their energy yield was measured over a period of one year (April 1, 2008 — March 31, 2009), the average wind velocity during these 12 months was 3.8 meters per second, slightly higher than average. Three windmills broke. The others recorded ridiculously low yields, in spite of the optimal conditions. It would take up to 141 small windmills to power an average American household entirely using wind energy, for a total cost of 780,000 dollars. The test results show clearly that energy return is closely tied to rotor diameter, and that the design of the windmill hardly matters."

Best Buy Coughs Up $54 Million For Napster 164

MarketWatch reports that Best Buy has decided to toss $54 million into an acquisition of Napster. All told, the deal amounts to around $121 million, with about $67 million headed towards getting cash and short-term investments from Napster's balance sheet. "The deal will give Best Buy an online digital music retail outlet as well as a subscription streaming service that has about 700,000 subscribers. That could help Best Buy to compete against retail giant Wal-Mart, which has its own online digital music offering."
