| 12 Small Windmills Put To the Test In Holland |  |
| 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."Read more of this story at Slashdot.

| Rugged Linux Server For Rural, Tropical Environment? | |
| travalas writes "Last year I moved to Rural Bangladesh. My work is pretty diverse, everything from hacking web apps to designing building materials. Increasingly a Linux VM on my MacBook Pro is insufficient due to storage speed/processing constraints and the desire to interface more easily with some sensor packages. There are a few issues that make that make a standard server less than desirable. This server will generally not be running with any sort of climate control and it may need to move to different locations so would also be helpful if it was somewhat portable. The environment here is hot, humid and dusty and brutal on technology and power is very inconsistent so it will often be on a combination of Interruptible Power Supply and solar power. So a UPS is a must and low power consumption desirable, so it strikes me that an Integrated UPS a la Google`s servers would be handy. Spec wise it needs to be it needs to be able to handle several VM`s and some other processor storage intensive tasks. So 4 cores, 8GB of ram and 3-4 TB of SATA storage seems like a place to start for processing specs. What sort of hardware would you recommend without breaking the bank?"Read more of this story at Slashdot.

| ECN Reaches 16.4% Efficiency with Multicrystalline Solar PV | |
| Researchers at the Energy research Centre of the Netherlands (ECN) said that they have achieved a premium conversion efficiency of 16.4% (aperture area) on a full-size solar module, a new world-record efficiency for photovoltaic (PV) modules with multicrystalline silicon solar cells. The previous world-record was held by Sandia National Laboratory, at 15.5% aperture-area efficiency. |

| Structuring Partnership Financings To Avoid HLBV Losses | |
| Structuring options can be used by tax investors to mitigate post-flip GAAP (generally accepted accounting principles) losses calculated by the Hypothetical Liquidation at Book Value (HLBV) accounting method for flipping partnerships. In some circumstances, these GAAP losses can dramatically affect the reported earnings for publicly traded companies and influence investment decisions in renewable energy projects. Project-level debt can exacerbate the effects on GAAP earnings, making structuring choices and other HLBV related loss mitigation strategies all the more important. |
