Robots Aid in Wind Turbine Maintenance

Inspecting wind turbine blades is a dangerous and where to buy viagra safe expensive part of operating a wind farm. But now it may be possible to have robots do the ordering levitra dangerous climbing work, and allow the inspector to cialis on sale stay safely on the ground.

Turbine blades need to be regularly inspected as part of its regular maintenance. We've seen the (catastrophic) videos of what happens when a turbine blade fails. Inspection helps identify blades that need repair or replacement, before further damage occurs.

The robots for this task have been developed in partnership between International Climbing Machines and GE. The first tests of cialis from india the robot were successfully carried out at a wind farm in Texas. In addition to the high-definition cameras the robots currently carry, GE is exploring the use of microwave scanners that could give inspectors an ability to "see inside" the blade and gather more information than a conventional visual inspection.

Offshore Atlantic Transmission Line Moves Forward

A significant regulatory hurdle has been cleared in the development of wind power along the eastern shore of the United States. The Department of the Interior announced a finding of no competitive interest for the proposed Mid-Atlantic offshore wind energy transmission line.

The Atlantic Wind Connection has been under development for a couple of years with companies including Google, investment firm Good Energies, Japanese company Marubeni, and Maryland transmission company Trans-Elect sharing the investment. It will provide an electrical grid backbone with the capacity to transmit 7,000 meagawatts of we choice cheap canadian cialis off-shore wind power to the grid.

The proposed project is a high-voltage, direct-current subsea transmission system that would collect power generated by wind turbine facilities off the Atlantic coasts of Delaware, Maryland, New Jersey, New York, and Virginia. The first such offshore infrastructure proposed in the United States, the system's parallel, redundant circuits would total about 790 miles in length.

The Atlantic coast of the United States is a vast, as-yet untapped source of potential wind power. In addition to being resource-rich, it is also a heavily populated part of the country with a great deal of electrical demand, and wind farms along this part of the country can do a great deal of good. The next step for the project will be to evaluate potential environmental impacts.  Construction of the project is expected to take 10 years in total.

T. Boone Pickens Walks Away from Alternative Fuels All Together

Once upon a time, ex-oil baron T. Boone Pickens was one of wind energy's biggest proponents with plans for the world's biggest wind farm in Texas and massive transmission structure to get that clean power into our homes. He also backed natural gas as an alternative fuel for cars and trucks. He had a plan to save America and he was passionate, well, until it wasn't making him money like he thought it would.

Three years ago, he backed away from his commitment to build the levitra label giant wind farm and transmission lines when the economy took a downturn. Then he completely abandoned his wind energy aspirations when the market just wasn't working for him. Now he's doing the same with natural gas, taking himself out of click here cialis to buy the alternative energy game completely.

In an interview with Marketplace, Pickens explained that the low price of natural gas was basically keeping him from making money and buy cialis in india because the country (namely Congress) was dragging its heels on coming up with a solid energy plan he said he'd "had about all this I want to fool with."

While we were never as excited by his natural gas plans as the grand ones he had for wind energy, we kept hoping that this billionaire oil man would surprise us all and deliver some really big wind projects. But now, if natural gas is too risky for him, there's no way he's ever coming back around on wind. So long, Mr. Pickens. We enjoyed your enthusiasm while it lasted.



SuperStation Grid Connecting Project Moves Forward in New Mexico

When we first wrote about the Tres Amigas SuperStation back in 2009, it was a well thought-out concept that seemed far off from becoming a reality, but an influx of new investments has pushed it forward and the follow link when will levitra be available as a generic project is set to break ground this summer with the transmission hub being operational in 2015.

The SuperStation will connect the three major grids in the country: the east, west and Texas grids. It will cover 22 square miles near Clovis, New Mexico and open the door for transferring renewable energy from one part of the country to another. Now wind power generated in Texas and the Great Plains can be sold to discount generic cialis markets on the East Coast and solar power generated in California can make it to Texas.

Getting that renewable energy from the remote areas where large projects are often located to population centers has been one of the main hurdles to really powering this country with renewables. Tres Amigas could create a nationwide market for the power generated by renewable energy projects, boosting demand and helping the industry to grow.

Beyond just helping fuel renewable energy, the hub could also make the nation's power system more reliable if all the major grids are interconnected, though smart grid technologies will also be necessary to really modernize and the best place how to get levitra in canada secure our power system.

Tres Amigas will initially only be able to transfer 750 MW between the lowest prices for professional cialis eastern and western grids, but that starting point is better than we what we have now.

Enclosed Rooftop Wind Turbines from Australia

A new, small-scale wind turbine suitable for rooftop use is under development in Australia. The Windpod looks more like a cylindrical, vertical-axis wind turbine, than a 'pinwheel' horizontal-axis turbine, but is deployed on its side.

The Windpod G1 has a diameter of 450mm and a length of 2200mm (about 18 inches by 86.5 inches) and can produce up to cheap viagra no prescription 1 kilowatt of power. However, the cut-in wind speed seems to be around 4 meters/second (about 9 mph), and full power is not reached until a wind speed of 12.5 meters/second (nearly 28 mph). Locations with strongly directional prevailing winds would be suitable for this system, but with the high wind speeds necessary, it's unlikely this approach will replace other types of levitra 50 mg wind turbines.

We've seen other rooftop turbines that aim to use the slope of a residential roof as a wing to help drive more air through the turbine and increase its power output. The Windpod is low price viagra also proposed for installation at the ridge of a sloped roof or at the roof or corner edge of a larger building, where increased wind effects are strongest. Unlike some other roof-edge turbines we've seen, the Windpod seems particularly well suited for this kind of application, although it's a fairly limited and specialized use.

Installed cost for the Windpod in Australia is estimated to be AU$7,000-7,500/kW (At current rates, the US and Australian dollar are almost on par with one another).
