Pimenta’s professor Willett Kempton pointed out two limitations with QuikSCAT’s measurements of wind speed. First, the satellite only measures winds in any given place once per day, far less information than buoys provide. “With buoy data, you can get down to five-minute or even one-minute time resolution,”--------------------------------------------------------------------------------------
Governor’s Offshore Wind Energy Panel Releases Interim Report
(TRENTON) – The Blue Ribbon Panel on Development of Wind Turbine Facilities in Coastal Waters today announced their interim report is publicly available and a public meeting has been scheduled to solicit feedback on the report. Acting Governor Richard J. Codey established the Blue Ribbon Panel by executive order last December. The panel is charged with studying the costs and benefits of developing offshore wind turbines. The interim report represents the progress to date toward meeting Codey’s mandate.
“I encourage the public to offer their comments on this important document,” Codey said. “This is an opportunity for residents to play a key role in shaping New Jersey’s clean energy choices. With the public’s help, we will be able to pursue the best options for our state.”
The interim report is accessible on the panel’s Web site at http://www.njwindpanel.org/.
During the next phase of their work, the panel will seek public input on the content, accuracy, and scope of the findings. Comments may be submitted to the panel through their Web site. The final report, including specific policy recommendations, will be submitted to Governor-elect Jon S.

Jorg Schlaigh, built a working model of a solar chimney power plant in 1982 in Manzanares (Spain), 150 km south of Madrid, which was funded by the German Government. This power plant operated successfully for approximately 8 years. The chimney had a diameter of 10 m and a height of 195 m, and the maximum power output was about 50 KW. During the final 3 years, optimization data was collected on a second-by-second basis.by Prof. Christos Papageorgiouchrpapa@hol.grwww.floatingsolarchimney.gr

U.S. Leads World in Wind Energy
August 18th, 2008 -
The United States has taken over from previous champion Germany in wind power production. For this USA has to be thankful to nature and human resource that produce technology. Nature has gifted USA with stronger wind than Germany. Randall Swisher, the executive director of the American Wind Energy Association, said that the US wind energy capacity is growing faster than anyplace else. But if we try to view those stats differently, Germany harnesses seven percent of their power from wind and Denmark generates twenty percent of power from wind. Wind energy only constitutes 1.2% of total power consumption in America.

Offshore windmills hold clean-energy promise
David R. Baker, Chronicle Staff Writer
Monday, August 3, 2009
Their blades would spin over deep ocean water, turning in winds that are steadier and stronger than they are on land. Undersea cables would send their electricity to shore.
This kind of floating windmill has not yet been deployed en masse. But a model of one sits in the Berkeley office of Principle Power, one of several companies trying to tap the powerful winds at sea.
Principle has signed agreements with utilities to test its device, called the WindFloat, off the coasts of Oregon and Portugal. Three connected canisters filled with ballast water will support a wind turbine, with cables mooring the entire device to the seabed.
"The most prolific minds in the renewable energy business are talking about taking land-based wind and dragging that power out to the coast, which really doesn't make much sense," said Jon Bonanno, the company's president. "It makes much more sense to generate that power from deepwater sources and transmit it to the coast."Read more: http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2009/08/02/BA0Q18ABIT.DTL#ixzz0NGLKRsTO

Offshore windmills hold clean-energy promise
Used in Europe
While the idea may be simple, executing it isn't.
Offshore wind farms have been used for years in Europe. But those windmills sit in shallow water, their bases bolted into the ocean floor. Wind farms proposed for the U.S. East Coast, including the contentious Cape Wind project off Massachusetts, take the same approach.
But the seabed off most of California's coast drops quickly, close to shoreRead more:

ViGYAN Wind Tunnel Expedites MAGENN Development
Magenn Power Inc., an Ottawa, Ontario, Canada-based company, has created the Magenn Air Rotor System, or MARS, an inexpensive, lighter-than-air, tethered wind turbine that generates electrical energy by rotating about a horizontal axis in response to active airflow at 600 to 1,000 feet in altitude. Electricity would be funneled down the MARS tether for immediate use, or sent to and stored in a set of batteries.
Because MARS would float well above ground-generated atmospheric disturbances and varying topographies, the turbine would benefit from cleaner, more consistent and faster air, thus producing more power than a ground-based unit.
The turbine's blimp-like design lets it operate in winds as low as two miles per hour. In the event of collision, the inflatable, inert and non-flammable helium-filled structure would fall slowly and harmlessly to the ground. MARS floats below legally usable airspace and therefore poses no danger to airplanes. And birds are less likely to be imperiled because the turbine's moving parts are visible and travel with the wind, not perpendicular to it.

OCEAN / WIND,
Concept Turbine
Air power: it has been likened to a gigantic rotary washing line but it could be the shape of things to come in the harnessing of offshore wind to provide clean renewable energy. With two giant V-shaped wings that will use the wind to spin and drive a ground-level turbine, this new design of offshore vertical-axis wind machine now under development offers new levels of efficiency, ruggedness and maintenance simplicity.
It is expected that a large-scale demonstrator will be ready for testing within six years.A revolutionary new wind turbine that promises to advance the harnessing of offshore wind energy through its ruggedness, extra stability and easier access for maintenance has been given the go-ahead. The newcomer could truly bring a wind of change to the public perception of huge windmill-like structures cluttering the seascape.
No longer is the structure just a gigantic propeller atop a cylindrical tower, but instead it is a pair of V-shaped arms up to 120 metres high with four rigid “winglets” along their length.The wings act as aerofoils with the wind generating the lift necessary to turn the whole structure at about three revolutions a minute, enabling the turbine at the foot of the arms to produce up to nine megawatts (MW) of electricity.
By contrast, today’s conventional turbines generate an average of 2MW.The Nova turbine (short for novel offshore vertical axis) has been invented by aeronautical engineer, David Sharpe and developed by the UK Wind Power company from Blyth, north-east England. The firm has already carried out wind tunnel tests on a small-scale version and the results suggest predicted power outputs can be achieved.The new design is said to work in a similar manner to a sideways water-wheel. One commentator said the structure, with its arms linked by steel cable stays, resembled a huge rotary washing line. It has been engineered to overcome the problems that inhibit the present generation of rotor-driven horizontal-axis turbines.
The problem with today’s horizontal-axis turbines is that they are top heavy because the rotors and generators are mounted at the summit of the tower where gearboxes also have to be located to turn the rotors into the wind.
The new design of spinning vertical-axis machine is more efficient in being able to draw wind from any direction and – with the turbine and other mechanisms located at ground level – the structure is bottom heavy and therefore much more stable and easy to maintain.Furthermore, the V-wing concept faces less constraints on scaling up the size of the turbines and this is expected to lead to larger-output offshore wind machines that would cut the number needed. read more online articles from this month
