BOSTON--Despite the growing enthusiasm for home wind turbines, an analysis of microwind turbines in Massachusetts found that they fell short of performance expectations.
The Massachusetts Renewable Energy Trust commissioned a study last year to review electricity output from 21 small wind turbines in the state and the results were surprising: the data showed that the estimated production was about three times higher than the turbines' actual production.
The analysis is not the final word on small wind generators, but is significant because few states have done similar reviews, say the study's authors.
The Massachusetts Renewable Energy Trust was "… Read more

The Maui Electric Company and General Electric are joining up to test a unique smart-grid technology on the Hawaiian island's electrical grid.
The Maui, Hawaii, project includes the usual smart-grid tech: developing a substation with battery storage capability to remove and store excess electricity generated from connected wind and solar energy sources. The electricity supply is then released from the substation to the main power grid when it's needed during peak usage times.
Many companies are interested in smart-grid energy technology. Google wants users to confront their home energy use appliance by appliance. IBM is jockeying to be a key supplier for smart-grid tech … Read more
Small wind turbines attached to individual homes work fine unless you have lousy wind.
That's the upshot of a multi-site study called the Warwick Microwind Trial project, a year-long survey on the performance of roof-mounted turbines done in the U.K. done by Encraft, a low-carbon technology consulting firm.
The researchers picked 26 sites in the U.K where microturbines tied to the power grid were attached to people's homes to offset their electricity use. Many of the consumers clearly purchased the turbines to lower their fossil fuel energy use as some already had solar panels and ground-source heat pumps. … Read more

MEDFORD, Mass.--Wind turbines themselves aren't exactly exotic--thousands of them are already installed around the world. But it is unusual to see a 150-foot-high turbine spinning next to a middle school football field.
The Boston suburb of Medford cut the ribbon on a 100-kilowatt wind turbine on Thursday in a ceremony that included speeches from the mayor and a long line of children. It is said to be the first commercial-size wind turbine installed at a public Massachusetts school.
The turbine at the John J. McGlynn Middle School will offset about 10 percent of the school's electricity, saving … Read more

WhoopieCushion is a free and extremely simple app that attempts to replicate the classic, red-rubber toy of the same name. Like the original toy itself, there are countless competing imitations--offering everything from timers to motion sensors--so shop around to find the right flatulence simulator for you. WhoopieCushion stands out because of its price (it is free) and its clean interface: you just tap the photo of the "Whoopee Cushion" on your iPhone or iPod Touch screen, and the app will randomly produce one of a handful of "Bronx cheer" noises. No similar app--this one included--can quite … Read more
