New design of Friction Drive Wind Turbines : No more need for a complex gearbox!
A Canadian startup has developed a small prototype Wind Turbine that uses friction instead of a gearbox to convert wind energy into electricity. CWind, based in Owen Sound, Ontario, recently began work on a larger two-megawatt prototype. The company claims that its "friction drive" system is more efficient and reliable--and less costly to maintain--than conventional wind turbines, which are prone to expensive gearbox failures.
The blades on most turbines use the wind to turn a drive shaft connected to a gearbox. The gearbox manages the rotation of a second shaft that connects to a large electrical generator. The gearbox is the heaviest piece of equipment in a wind turbine's "nacelle" (the section at the top of the turbine tower). It's also a piece that's among the most vulnerable to failure. Sudden wind gusts put the gearbox under tremendous mechanical stress. Over time this can wear down or break the teeth off its metal gears.
CWind's design does away with the gearbox completely. Instead, the drive shaft is connected directly to a large metal flywheel. Hugging the outside of the flywheel are eight smaller secondary shafts, each connected to a 250-kilowatt generator and each lined with several specially designed tires that grip the surface of the flywheel. As the flywheel spins, it engages the generators by turning these tire-lined shafts. "We're using friction. It's not mechanically hard-coupled," says Na'al Nayef, a CWind engineer and co-inventor of the system.
Nayef says the system uses software to control the eight secondary shafts. The tires are also designed to temporarily slip if a wind gust causes the flywheel to suddenly speed up. This feature eases the impact on the generators. Each secondary shaft can also be disengaged from the flywheel if the wind slows down, in effect reducing friction and allowing shafts that are still connected to keep their generators operating at high capacity. Likewise, connecting more shafts, thus adding more friction when the wind increases, will engage idle generators. "We can operate the generators at optimal speed all the time," says Nayef, adding that tests on the smaller, 65-kilowatt prototype show efficiency gains over standard wind turbines of up to 5 percent.
World's largest wind energy center breaks ground in California
The largest wind energy project will soon rise in Kern County, California as Terra-Gen Power began construction of the 3,000-megawatt Alta Wind Energy Center.
Comprising of a portfolio of wind energy facilities, the wind center will dwarf the 781.5 MW Roscoe Wind Farm in Texas, which currently holds the record for the largest wind generating capacity in the world.
A project under the Alta wind center is the 800-MW Alta-Oak Creek Mojave project, which consists of 320 wind turbines. The wind farm is expected to be completed in early 2011.
The Alta wind center will generate enough wind energy to sustain the electricity needs of 1.1 million people, which is roughly the equivalent of 275,000 Californian homes. Southern California Edison already purchased 1,550 MW of the energy generated by the wind center under a power purchase agreement signed in 2006.
Upon completion, the project will also increase California's installed wind energy capacity by 25 percent and will represent 10 percent of the renewable power purchases required for the state's regulated utilities. The state's renewable portfolio standard mandates utilities to source 33 percent of their energy supply from renewable by 2020.
Terra-Gen expects the Alta project to offset more than 52 million metric tons of carbon dioxide – the equivalent of removing 446,000 vehicles from the road – and conserve over 888 million gallons of water annually.
More than 3,000 jobs will be created during the manufacturing, construction and operational stages of the project, increasing California's wind industry-related jobs by 20 percent. The project will also inject $1.2 billion in Kern County's local economy.
"[Alta Wind Energy Center] will create a record-breaking amount of domestic wind energy, securing America's energy independence while protecting our natural resources for future generations," said Jim Pagano, chief executive of Terra-Gen Power.
"Having the world's largest wind project break ground in our state is tangible evidence that our pioneering policies are drawing investment, improving the economy and creating jobs now when we need them most," added Arnold Schwarzenegger, governor of California.
The Alta Wind Energy Center will be equipped with nearly 600 wind turbines, 190 of which will be provided by Vestas-American Wind Technology. Amounting to 570 MW of wind energy, this is the largest wind turbine order that Vestas received for a single site.
Terra-Gen already secured over $1.5 billion in financing for the wind project through a variety of funding efforts, including a construction financing round, a construction bridge loan facility, and ancillary credit facilities.
A more efficient Wind Generator could convert more of the wind's energy into electricity.
ExRo Technologies, a startup based in Vancouver, BC, has developed a new kind of generator that's well suited to harvesting energy from wind. It could lower the cost of Wind Turbines while increasing their power output by 50 percent.
The new generator runs efficiently over a wider range of conditions than conventional generators do. When the shaft running through an ordinary generator is turning at the optimal rate, more than 90 percent of its energy can be converted into electricity. But if it speeds up or slows down, the generator's efficiency drops dramatically. This isn't a problem in conventional power plants, where the turbines turn at a steady rate, fed by a constant supply of energy from coal or some other fuel. But wind speed can vary wildly. Turbine blades that change pitch to catch more or less wind can help, as can transmissions that mediate between the spinning blades and the generator shaft. But transmissions add both manufacturing and maintenance costs, and there's a limit to how much changing the blade angle can compensate for changing winds. 
ExRo's new design replaces a mechanical transmission with what amounts to an electronic one. That increases the range of wind speeds at which it can operate efficiently and makes it more responsive to sudden gusts and lulls. While at the highest wind speeds the blades will still need to be pitched to shed wind, the generator will allow the turbine to capture more of the energy in high-speed winds and gusts. As a result, the turbine could produce 50 percent more power on average over the course of a year, says Jonathan Ritchey, ExRo's chief technology officer. Indeed, in some locations, the power output could double, says Ed Nowicki, a professor of electrical engineering at the University of Calgary, who has consulted to ExRo.
The generator works on the same principles as many ordinary generators: magnets attached to a rotating shaft create a current as they pass stationary copper coils arrayed around the shaft. In ordinary generators, all of the coils are wired together. In ExRo's generator, in contrast, the individual coils can be turned on and off with electronic switches. At low wind speeds, only a few of the coils will switch on--just enough to efficiently harvest the small amount of energy in low-speed wind. (If more coils were active, they would provide more resistance to the revolving magnets.) At higher wind speeds, more coils will turn on to convert more energy into electricity. The switches can be thrown quickly to adapt to fast-changing wind speeds.
New Wind Power Platform Able to Support World's Largest Wind Turbine
Principle Power is a renewable energy company committed to environmentally sustainable deep water offshore energy. Currently, offshore wind projects have limitations on water depth and distance from shore. They need to be close enough to land so that the waters are shallow enough to anchor the base of the turbines into bedrock. Principle Power thinks their WindFloat can solve those issues. It doesn't need to be anchored to bedrock, thanks to its sturdy floating base, and is large enough that you would need to install less turbines to get the same energy output.
The researchers at Principle Power have just released their feasibility study proving that the WindFloat is capable of carrying large scale turbines in rough waters without becoming destabilized. They've designed the turbine so that it can be assembled onshore and then carried in full out to its installation space – a process that decreases the costs of the turbines installment. Once at sea the whole head of the turbine spins to follow the direction of the wind, maximizing energy output. With a 5 megawatt capability, the WindFloat seems like a great addition to the offshore renewable energy world.

Are Solar Panels truly Ecologic or they producing more pollution?
This is a question I ask myself for some time. We see a little bloom everywhere Solar Panels for the production of clean energy. My question that arose was, therefore, it "It takes energy and raw material to produce a solar panel, so after how long it was there a positive energy balance, it is ie it produces more energy than it took to its production.
The answer:
Believing that the manufacture of a solar panel consumes more energy than it provides during its lifetime is a myth. This is true for solar panels designed for the space environment, given the conditions under which they will evolve and they must have a very good performance, it does not count the energy needed to produce them and they will surely never profitable. But this is false for terrestrial solar panels. Of course, everything that occurs on Earth requires energy and, in order to estimate the value of energy product, we created the "energy balance" is simply the ratio of energy out (energy) on the incoming energy (energy required for product realization and / or production of energy out).
Example:
In the case of corn ethanol, energy balance was equal to 1.3, ie one gets 1.3 units of energy for a unit of energy needed to produce it. Ethanol from sugar cane (Brazil) it has a better energy balance, you get eight units of energy for a unit of energy necessary for its production, energy balance is equal to 8. As for gasoline, its energy balance is about 5.
But on the solar panels, it must do so? This seems wrong to apply the energy balance to solar panels because they "contain no real energy." But as they produce during their life, it is still possible to use this variable.
A study by Energy & Environmental Economics, Inc. and Siemens Solar Industries (scientists will be pleased with this study ;-)) shows that the average solar panel produces 5 times more energy than it has been necessary to production. Roughly equivalent to energy balance than gasoline (though on a time scale much longer).
The problem is that nobody is satisfied with this figure. Currently the community working on solar panels (scientists, engineers ...) seeks to increase the energy balance of the latter, that balance has been significantly improved in recent years. One of the simplest methods is to ensure that the solar panel is oriented at an angle of 90 degrees to the sun, its life is increased and the number of photovoltaic cells required is reduced.
The photovoltaic cells are very inefficient (Poly-silicon) during their production, we must try for the same efficiency to use as little as possible. One solution is to use mirrors or targets that will focus sunlight on photovoltaic cells leading to lower surface area needed (the lens effect) and therefore a smaller solar panel. Another approach is the use of materials that require less energy to produce (eg thin films DSCIG (Copper Indium Gallium sulfide) .... I'll spare you the technical details ...).
In conclusion, the solar panels have a very interesting and energy balance in their lives will produce much more energy than it has been necessary to manufacture them ... do not deprive ourselves of solar panels, especially since this energy balance continues to increase with new generations.

Home Wind Turbine Technology : Lower your electric Bills!
Companies are constantly working on new technology in Wind Turbine. Different types are tested for durability, performance, and efficiency. Wind turbine companies expand to a global field. Just as wind turbines are all over the world today.Even though wind is the essential key to the wind turbine's performance, the newly discovered technology goes beyond today's state-of-the-art mega-watt-class wind turbines. To give you an idea at a glance, of how wind turbines are being improved and inspected. Giving alternate energy information and letting you know the certain changes in the wind turbine as well as the generators and other equipment associated with the wind turbine.
The Air-X Wind Turbine, distributed by Southwest Wind power, uses a new microprocessor based technology, creating an increased performance for the Wind Turbine. The Air Turbine is the world's number one selling small turbine. It has improved battery charging capabilities as well as a reduced "flutter" noise from the machines. This comes from the use of the carbon fiber composite blades.
The development of research on wind turbines has increased since 2001, as more customers are in the market for alternative energy systems. Newer designs much like the Air-X are also equipped to actually shut down during large wind gusts to prevent damage to the machine. It takes just an eight mile an hour wind to get a turbine going. For optimal performance, a twelve mile an hour wind is all that is required for a small home used wind turbine.
Researchers are hoping to have wind farms all over the United States, funded by the government. These wind farms will not only help out the economy by using a natural resource, but allow companies to expand their technology on the wind turbine even further.
By tracking and observation, of the wind turbines improvements on blade turning, weight of the tower, height of the tower, and many other conditions. The higher advanced wind turbines consist of many parts. Gear boxes, rotation devices, magnetic mechanisms, and other parts that ensure the quality and performance of the machines.
The wind turbine is capable of handling extreme wind conditions and windy environments. However those closer to the coast require different specs, such as heavier gauged towers and blades. These turbine machines also have more than three blades in most cases.
Enjoy the benefits of utility power and reduce your electric bill every time the wind blows. This utility-connected system with the use of wind turbines has its incentives.
Though the image of the Windmill has changed tremendously, the Wind Turbine instills the same concept for small homes, and creating electricity by a windmill.
On a last note, the horizontal windmill is not in as high of a demand as the vertical windmill. Vertical windmills or Wind Turbines are used to create power, while the horizontal windmill was used mainly for irrigation and grinding grain. Both types are still an active part of our environment today.
Wind turbine technology improvements are essential for the further development of future wind turbines manufactured. What types work on homes, and what types work in wind turbine fields. Windmill power can be an alternate source of energy for our generation, as well as generations to come.
Flat Solar Panel Technology Boosts Solar Efficiency
Xtreme Energetics has investigated the possibility of using mechanical trackers to perform the same light-focusing duties as other solar array manufacturers have. However, HP's transparent transistor can do the job electronically, rather than mechanically, and significantly reduce the costs of such an installation. Such a solar array is known as a concentrating photovoltaic (or CPV) solar array. To date, CPV arrays are fairly expensive and cannot store energy, making them less useful. They also work best in specific sections of the world — those with the highest levels of solar radiation, such as the southwest United States and northern Africa.
The company intends to build a multilayered solar panel containing the transistor, a high efficiency solar cell and a light concentrator. The whole system will be effectively transparent, allowing companies to put various designs and patterns — such as logos — on the panels, before mounting them on rooftops and sides of buildings. So not only will a company be able to power its business with an Xtreme Energetics solar array, it will also have the option of using the panels for advertising!
Xtreme Energetics is in the process of raising venture capital. Currently, the company is in the middle of a series A round of venture funding expected to raise $5 million, and is planning for a series B round to raise an additional $35 million. Xtreme Energetics has yet to build a product, or even a prototype, but there's plenty of buzz in the solar energy sector about similar technology. To obtain the license from HP, Xtreme Energetics agreed to pay royalties, although the specifics of the deal are still unknown. Recently, HP has been more open to licensing its technology to industries unrelated to HP's main businesses.

Costs for Thermo-photovoltaic Cells Significantly Reduced
Thermo-photovoltaic (TPV) cells are great for converting radiation from any heat source to power. These cells can generate power from the wasted heat which gets released when glass or steel is produced. Adding these TPV cells to domestic power systems can help generate power along with heating water. TPV systems are also too complex for everyday use. Both of these reasons have made the TPV systems beyond industrial and domestic consumer routine set-up.
Prohibitive cost:
Though TPV cells can be utilized to enhance the domestic heating system efficiency, the cost is a daunting factor in deploying cated on epi-ready substrates, these cells were marketed for III-V layered epitaxial growth.
Unique new processing technique:
But IMEC has been researching newer and better techniques. IMEC has used amorphous Si by diffusion and passivation to form the emitter. Ge substrates specially designed were created and tested. Ge substrates defined (germanium-based) TPV cells had better quantum efficiency as compared to epi-ready started traditional TPV cells.
Benefits of new method:
The increased efficiency of the germanium-based TPV cells can means more electricity generation from waste heat. An increase in cell performance and reduction in cost are the direct outcome of the surface passivation techniques and the new contacting technologies that had been uniquely developed by IMEC. The new TPV cells will be crafted up on the special germanium substrate designed and created just for this.
IMEC's contribution:
Jef Poortmans, Director Photovoltaics, IMEC, claimed, "IMEC's research into photovoltaics aims at finding techniques to fabricate cost-efficient and more efficient solar cells." IMEC has had a long innings in making silicon solar cells and this has been instrumental in the success of their TPV research.
Better future:
As band-gap of the germanium is very near the emission peak of the TPV system emitters, germanium-based photovoltaic devices can be found as the suitable receivers for these kinds of systems. Now with the decreased cell cost because of the better processing techniques, the future of the market for thermo-photovoltaic applications looks brighter.
Project Focus: S.A.G. Solarstrom to construct 48MWp system in northern Italy
S.A.G. Solarstrom is to construct a 48MWp ground-mounted photovoltaic power plant in region of Veneto, in the municipality of Canaro, northern Italy. This is the largest project to be planned by S.A.G Solarstrom to date.
The project will be managed by S.A.G., who will work together with cooperation partner, Solibra Solar Solutions. S.A.G. will also apply financial resources from the refinancing of completed projects in the first stage.
The system, which will be constructed on a total area of 150 hectares, has received all necessary approvals so that work on construction of the power plant can be started. S.A.G. is building its own transformer substation that will allow the system to be connected directly and the electricity to be fed into the high-voltage grid; this will then be sold to Italian company Terna once the project is complete.
The project will be implemented in 2010 and 2011 and substantiates the forecast for 2010 with sales of between €190 and €210 million and an EBIT of between €8 and €11 million.
A new solar panel to heat your home
A Canadian Tire flyer that they were selling solar panels for residential use. At almost $2000 they were pretty pricey and the wattage they put out might power a 60 watt light bulb and a small radio.
Geothermal sounded great to us as it was a way of "getting off the oil tit" entirely. Unfortunately we live in an eighty-year-old house and the retrofit would have doubled the already hefty price (around $20,000) for the unit. And because it runs on electricity, your light bill goes up drastically.
Then we thought "Hey wind power! Of course!" but with local zoning laws and a low buy-back rate from the regional electric company for surplus electricity, we had to nix that idea too.
Supplementing oil heat with wood heat is very popular in our area and we considered this option as well. But with both of us working full time we couldn't see us chopping wood and starting fires for hours a day. There's also the storage and mess when dealing with wood that really killed our interest in pursuing it as an option.
Enter James Meaney of Dildo, Newfoundland and his company Cansolair, that manufactures solar panels for heating your home. Unlike conventional solar panels that convert solar energy into electricity used to heat up water using an electric water heater, the Model RA 240 Solar Max is a forced convection solar heating unit.
Cold air is pumped by a small fan from the bottom of a room through a small duct into the solar panel where it is heated up and then pumped back into the room. According to Mr. Meaney, all you need is fifteen minutes of sun an hour for the unit to start saving you money on your heating bill. The price was a draw as well — only $2500 per unit.
Most forms of alternative energy available to the average homeowner cost a lot of money to set up and don't "pay for themselves" for around 20 years. It can be a major investment and is usually best done when the house is built. With some testimonials stating a savings of a tank of oil per Cansolair panel, the unit would pay for itself in three to six years.
Cansolair is currently building its distribution but has already been sold in Australia, Europe and North America. They are currently working on adapting their solar panel design for other uses like water heating. Good luck to this Canadian inventor. He'll be hearing from us soon!

Boat Solar Panels - Alternative Way of Powering up Boats
If you own a boat or any form of small marine vessel, would you consider running it on Boat Solar Panels or Boat Wind Turbine? The fact is that not many people are using the energy from the sun to power their boats. For one thing, the solar panels would be hard to use during night time.,
However, some boats are now utilizing boat solar panels to run some of their vessel's small appliances such as fans, ovens, cookers and lights. For those who might be interested, there are many boat specialty shops that sell solar kits to create even just partial power from solar energy. Such kits have all that you need to use and enjoy solar power for your boats including the photovoltaic panels themselves, the wires and other important equipment.
It is a good thing that some boat owners have seen the potential of solar power, that's why they use boat solar panels to power as much as they can on the boat, rather than utilizing diesel. It is a known fact that the utilization of solar energy is a boon to the environment as no pollutions is ever caused with the use of photovoltaic panel devices.
Another advantage of boat solar panels is that it is a quiet way of running the boat. On the other hand, diesel run marine vessels tend to produce irritating noise. Not only do they produce pollutions in the form of emissions, but they also create what is called noise pollution.

Flat roof with new kind of rolled thin-film Solar Panels.
Roof with thin-film Solar Cells from a combination of copper, indium, gallium, and selenium which is placed on a flexible foil. Its first product line is a set of solar panels designed for the flat roofs of commercial buildings. The panels are lighter than glass-encased panels and can be installed quicker than other technologies, SoloPower CEO Tim Harris said in a statement. The panels can be laminated onto rooftops and mounted on racks to tilt the panels, Harris told Gunther Portofolio.
Homeowners have long been able to partially power their homes with sunlight, but it meant clumsily mounting photovoltaic (PV) panels on the roof. Now the latest generation of PV panels look and act much like ordinary roofing tiles or shingles. And the National Institute of Standards and Technology (NIST) is evaluating nine of these commercial PV roofing products in hopes of providing an easy way for consumers to judge the panels' power potential.
"A lot of people are considering the use of PV products on their homes and businesses, and in order to make decisions on whether it's a worthwhile investment you need to predict their performance," says Hunter Fanney, head of NIST's Heat Transfer and Alternative Energy Systems Group in Gaithersburg, MD. "We are collecting detailed performance data to validate those models."
