The three companies receiving government grants are: * Clipper Windpower: £4.4 million to develop its first prototype 70-metre blade for the Britannia project - the largest wind turbines in the world; * Artemis Intelligent Power: £1 million to transfer its existing technology from automotive to wind energy; and * Siemens Wind Power UK: £1.1 million to develop the next-generation power converters for its larger offshore turbine.

"The results show that no urban or suburban sites with a building-mounted turbine generated more than 200kWh (or £26 of electricity) per annum, but the best performing building-mounted turbine, located in a rural area of Scotland, generated nearly 1,000kWh (or £127 of electricity) per annum. Larger free-standing pole-mounted turbines, sited in rural locations, could generate in excess of 18,000 kWh (or £2,300) per annum."

"Replacing older oil-fired technology at the site, the gas turbines will increase the plant's efficiency and reduce its environmental impact in line with the Portuguese government's regulation to promote efficiency and reduce carbon dioxide emissions (Fig.1). Approved in January 2010 and in support of the European Union cogeneration directive, a new Portuguese law will regulate cogeneration on a national level."

If we want innovation, reliability, longevity in renewables, too much focus on cost is likely to be counterproductive.

Missouri's a pretty tough place to grow most crops. But there's one thing they've got plenty of: wind. So a small town, Rock Port, has decided to use the powerful breezes to its advantage, building four wind turbines to provide power to their town.

Driving south out of the agricultural town of Ainsworth, you can't miss its newest crop: wind turbines, three dozen of them, with steel stalks 230 feet high and petal-like blades 131 feet long, sprouting improbably from the sand hills of north-central Nebraska, beside ruminating cattle. Though painted gray, the turbines stand out against the evening backdrop of battleship-colored thunderclouds and bear an almost celestial whiteness when day's light is right. Airplane pilots can spot them from far away, and rarely does a bird make their unfortunate acquaintance. The sound of 8.5-ton blades, three to a turbine, turning and turning, only enhances their almost supernatural presence. Standing at the base of a turbine's stalk, you hear a whistling whoosh - whuh ... whuh ... whuh - as steady summer winds come like the breath of gods to toy with pinwheel amusements.

Historically, wind technology has been seen on land and near offshore locations. Restrictions, such as prohibitively expensive offshore foundations to support wind turbines larger than 20 meters, may be viewed as stunting potential market growth. Now, new technology based on floating turbines may enable deeper offshore placement. The view mentioned with this news is that pushing turbines further out to sea will equalise the issue of aesthetics. However, the real issue here is can this technology deliver a useful and economic addition to the grid.

Picture a kelp bed on the ocean floor swaying in the current. Done? Now picture an underwater field of bioWave turbines (pictured to your left) doing the same

To be explored after we've fully exploited energy efficiency's potential, and all the onshore and offshore technologies we can think off. But the market will take care of this automatically, unless the EU comes up with the idea of a kite directive ...

Clipper Windpower has announced that is has chosen Blyth, Northumberland in the United Kingdom as the site for the development of its new offshore wind turbines. Called the Britannia Project, the $65 million development program will develop a 7.5 MW wind turbine using Clipper's technology. North England's Centre of Excellence for New and Renewable Energy will provide engineering, testing and development services in support of the project.

Maglev Wind Turbine Technologies to Start Operations Sierra Vista, Arizona [RenewableEnergyAccess.com] Proposes to build one gigawatt wind turbine requiring less than 100 acres and working at wind speed up to ~150km/h.

A small team of engineers based in Cornwall, England, have made a breakthrough with the development of a turbine that they claim could solve the commercial viability of tidal power. Known as the Osprey turbine, the technology can be used to create electricity offshore at sea -- or in tidal rivers and inland waterways. The Osprey turbine is a vertical axis free flow device which produces power independently or as part of a larger system. Power output is expected to be from 1 kW up to 5 MW in a multiple system.

Wind Turbine Generator " Anodized Aluminum body with all stainless steel hardware " Alternator: 3 Phase AC Brushless Permanent Magnet. Endurance Wind Power manufactures home windmill power generators, wind power less than the custom permanent magnet generators all other small turbines employ.

We can turned fast, the magnets flew off, and the wind generators were destroyed. the EXCEL's purpose-built direct drive 38-pole permanent magnet (PM) alternator.

Engineers at Purdue University and Sandia National Laboratories are using a system of sensors and computational software to improve the efficiency of wind turbines by allowing them to adjust to wind conditions.
