]]> http://www.hfanlx.cn/archives/300/feed 0 Proposal made for Quincy’s first residential wind turbine http://www.hfanlx.cn/archives/295 http://www.hfanlx.cn/archives/295#comments Sun, 28 Nov 2010 12:26:58 +0000 admin http://www.hfanlx.cn/?p=295 The first proposal to install a wind energy turbine on a residential property in Quincy is before the zoning board.

Sunwind LLC, a Brewster company, wants to install a 10-foot turbine on top of a waterfront home on Post Island Road in Houghs Neck. The turbine will not be affixed to a freestanding tower.

The board of zoning appeals has scheduled a Dec. 7 city hall hearing on the proposal, though the applicant has requested a postponement.

The turbine’s primary purpose would be to power the single family home at 68 Post Island Road, said Timothy Holmes, president of Sunwind. The wind turbine will be connected to the power grid so that any unused power it generated could be sold to the power company in the form of bill credits, Holmes said.

Jay Duca, Quincy’s director of inspectional services, said more discussion is needed about the proposal’s potential affects on neighbors, such as light flickering.

“As far as determining the effects and impacts it’s going to have on adjacent property owners, I don’t know,” Duca said. “It may be just fine, but they’ve not brought enough documents in to answer those questions.”

Duca said the residential small wind  turbine proposal is the first of its type in Quincy. The city of Boston is working with Quincy to propose a municipal turbine on Moon Island, which is in Quincy limits but used by Boston for fire training and other purposes.

Holmes said the owner of the Post Island Road home, Charles Cote, wants the turbine to supplement a solar photovoltaic system he has already installed on his roof. Holmes said the solar power combined with wind power would make up about 75 percent of Cote’s annual power needs.

Cote has actually applied for permission to install two Swift-brand wind turbines on his home. The first would be located on the eastern side of his property, the second on the northern edge.

One would be installed shortly after city approval, the second within six months, according to a project outline filed with the city. Each 10-foot turbine would be mounted on the 39-foot-high home, putting the total height at 49 feet.

City regulations allow for wind facilities in residential zones, but require a turbine be set back 1.5 times its total height from the property line to guard against a wind  turbine falling over and landing on neighboring buildings.

Holmes is seeking a zoning board exemption from the requirement because the proposed turbine would be attached to a home.

“Our stance is it’s mounted to the building so it’s not going to fall over,” he said. “It’s not your typical mounted turbine that’s in a tower in the back yard.”

The diameter of the turbine blades is seven feet. The blades will be connected by an outer ring that eliminates sound typically emitted from a turbine, according to the project outline.

The outline states that two measurements of ambient sound at the site found that the turbine operating at all speeds is quieter than the surrounding ambient sound level and complies with state noise regulations.

Sunwind, which opened two years ago, has installed a similar residential wind generators in Truro and has received permits to install two in Orleans, Holmes said.

]]> http://www.hfanlx.cn/archives/288/feed 0 Plans halted for wind turbine at Oak Harbor High School http://www.hfanlx.cn/archives/285 http://www.hfanlx.cn/archives/285#comments Sat, 20 Nov 2010 14:16:23 +0000 admin http://www.hfanlx.cn/?p=285 Earlier this month, Village Administrator Robert Pauley announced Tim Rathbun, the CEO of SUREnergy, had withdrawn an application for zoning changes that would allow for a wind turbine to be constructed within the village limits.

Rathbun said state and federal governments award different types of grants, depending on whether the energy is provided by a commercial provider such as FirstEnergy or a municipal provider such as the Village of Oak Harbor.

According to Rathbun, in similar situations at Huron and Margaretta schools his company has been reimbursed about $380,000 for a $500,000 project, leaving the “gift portion” from his company costing about $120,000.

“In the case of Oak Harbor, they’re not eligible. That location is not eligible in the state program … $320,000 is the remaining balance and we couldn’t come up with enough gift money for it,” he said.

SUREnergy is left with two options — pursue the project in a location outside the village limits, or apply for another grant.

The USDA has a $125,000 grant available, Rathbun said. “It’s not a guaranteed grant. You have to apply for it, and early next year they make a determination.”

Zoning requirements are part of the application. The company asked Oak Harbor Village Council to waive the $1,250 in fees for the permit process during wind power turbines the Oct. 18 meeting. Council refused, at least in part because much of the money goes to “hard costs” that the village would have to pay out-of-pocket.

“I didn’t want to spend the money on the permitting before I know whether the USDA grant is available. If it’s not, the project dies and we would try to do something at Graytown or Rocky Ridge or one of the other schools,” Rathbun said.

He plans to submit the application with an outline of how he plans to deal with the zoning issue.

“No one issue passes it or fails it. Having the permit in hand secures you five points,” he said. “If you can secure that five points in another way, then it doesn’t matter.”

Rathbun said Pauley had been helpful in describing how the process works so he can fill out the application.

Diane Kershaw, the superintendent of the Benton-Carroll-Salem schools, said she’s excited about the project.

“There are a lot of hoops to jump through, and we’re doing this one step at a time, and we very much would like this project to move forward, and we’re more than willing to do what we have to do,” she said.

She’s open to the idea of having a wind generator at one of the elementary schools. “As far as the district is concerned, any of those places would be fine,” she said.

If the turbine were at the high school, it could be used for science or agricultural education.

“It makes the most sense to be at the high school, but we certainly could make it work wherever it would go,” Kershaw said.

In the current trend to promote green energy, the United Kingdom, the United States and Norway, an engineer being the giant wind turbines in a race. UK Arup-designed building in the sea on this, the new turbine generators (AerogeneratorX), power generation capacity of 10 megawatts, the huge machine size is twice the normal model, I believe because of this global energy market New generator and change. Blade span 275 meters – According to China Net epoxy / resin industry in China Online (www.epoxy-e.cn) describes this simulation rotation sycamore leaves design inspiration from the floating oil platform technology . Technological leadership in the Arup engineering company, will work with the Rolls-Royce, Shell and BP, including several blue chip companies funded by academic groups, such detailed design of wind turbines, the wind generators axial rotation, leaves a wingspan of up to 275 meters. After the initial 2-year trial is expected, 1 unit will be completed by 2013 ~ 2014. However, the British design team, including the design of the Garden of Eden project Grimshaw Architects, and other groups have to fierce competition. Earlier this year, and the U.S. Department of Energy’s Renewable Energy Laboratory, a close U.S. wind power company Clipper announced that they will plan to build North East of England called “Great Britain” 10-megawatt wind turbines.
The traditional scaling of wind generator is the popular practice of the United Kingdom, these behemoths will be fixed on the seabed, about 600 feet above the waves. Clipper claims that, if technically and economically feasible, each unit in its 25 years of useful life of the power generated, can supply 5,000 to 10,000 households use, the equivalent of 200 barrels of oil produced energy. At the same time Norway’s Sway company plans to build giant floating turbines, this turbine directly connected to the 100 m deep sea bed, called “mast” of the anchor. An EU-funded Research Institute plans also create 8 to 10 MW turbine. Also some companies the United States and Denmark are being made over from 9 MW unit of work. All of these design full-size model would be completed in three years. Offshore Engineering Cranfield University, UK head of South said: a wonderful intense athletic competition is staged. The winner of this contest will have access to the global offshore small wind turbine market dominance; British offshore wind power generation may start some Man-but four years with gas oil mining experience, we have the opportunity to lead the world. The new wind turbines in the semi-submerged oil platform technology based on the construction, and not the traditional wind turbines in the weight limit. The new turbine design is its high level of conventional turbines with the half. He also added that the extension of this technology, it can produce 20 megawatts or more wind turbines. Currently the largest installed wind turbines in the rated power of about 3 MW. In contrast to the power plant had gigabit level, about 180 sets of this new type of wind turbines, only the equivalent of one of Scotland North Ayrshire coal-fired power plant capacity. Engineers believe that wind power is OK, the key lies in the construction of the scale.

The appearance of this wind turbine generator compared with the conventional wind turbine is completely different, its height is 17m, much like a huge object squatting on top of the hill, while the conventional wind turbine was a slender body, standing high on a hill.
This is put into operation the first commercial wind generator -enhanced diffusion body (DAWT: diffuseraugmentedwindturbine), if the developers achieved the expected results will lead to a significant reduction in the cost of wind power. In testing new wind turbine technology, but also test-proliferation body rings can cover new materials, high-strength steel fiber reinforced concrete. Such wind turbine, known locally as “concrete wind turbine.” In business, it is called Vortec7 type small wind turbine, because it has a 7m diameter of the rotor.
Wind turbine by the nearly 100 small-scale investors set up a private company-Vortec Energy Limited responsible for the design and construction, the company raised 3.5 million U.S. dollars developing the prototype. Vortec Energy Limited is currently being further raise about 700 million, plans to build two 20m rotor diameter of the unit. One of the new units will be in areas of high wind speed test, it is possible near Wellington in New Zealand, another in the average wind speed zone. South Australian Government has expressed great design interest and will accelerate in the near Adelaide Anzhuang average wind speed unit, because the state government that is a little wind and renewable energy, technological breakthroughs needed to drive from the dominant state lower average wind speed resource development.
Two new rotor diameter of 20m the unit successfully running, Vortec Energy Limited will consider the possibility of listing in the Nasdaq stock exchange. Vortec7 unit performance data show that the design of the rotor diameter of 20m to less than 0.031 U.S. dollars to / kWh price of Internet access, it will make wind power can compete with New Zealand’s existing power plants, power generation and other than the new, more competitive. If the Vortec-type function to such a price level of wind power, wind power generators development in that it will quickly become a powerful new force.
Vortec Energy Ltd. backing entrepreneurs RobinJohannink, he successfully ran a business, but also PacificLithium Corporation (lithium extracted from seawater, a company) backing. Mr. Johannink say Vortec technology is an international product, but the technology in New Zealand stock market gained recognition and attention is not too difficult in this market. So Vortec Energy Ltd is considering New York’s Nasdaq Stock Exchange, it is possible to achieve in 1999.
