Inflatable Vertical-Axis Wind Turbine

Dean Kamen, the inventor who is perhaps best known as the inventor of the Segway, has filed a patent for an inflatable vertical-axis wind turbine, which could be rapidly transported to locations where it was needed.

The patent application for this seems to be less about renewable power generation and buy levitra without is focused more on the attached LEDs being used as an animated display system. While it might be usable as a rapidly deployable system for power generation after an emergency, other portable wind-power generators seem more promising to be able to generate enough power to be useful in the aftermath of a disaster. Nonetheless, it is always interesting to see new developments in wind power technology.

City of i use it buy cialis Austin Facilities Now Fully Powered by Renewables


The City of Austin, Texas is now the largest U.S. municipality to cheap viagra canada or india use only renewable energy to power its facilities.  The city uses Austin Energy's GreenChoice, a voluntary program, to buy their electricity.

The city has bought about 400 million kWh of renewable energy from the program that will get the canadian healthcare pharmacy electricity from a wind farm in West Texas.

According to the National Renewable Energy Laboratory, Austin Energy sold more renewable energy than any other U.S. utility in 2010, selling 754 million kWh electricity from wind and landfill gas.

Carbon Nanotubes Make Wind Turbine Blades Lighter and Stronger


A scientist at Case Western Reserve University has discovered that adding carbon nanotubes to a traditional mix of plastics used in wind turbine blades could make them much lighter and stronger, meaning that future blades could be much more efficient while also requiring less maintenance.

The study found that carbon nanotubes are lighter per unit of volume than carbon fiber and aluminum and had five times more tensile strength than carbon fiber and 60 times more than aluminum.

If those carbon nanotubes are mixed with a polyurethane composite, the material lasts eight times longer than an epoxy reinforced with fiberglass and it was eight times stronger in fracture tests.  Compared to a vinyl ester reinforced with fiberglass (another material commonly used in wind turbine blades), the carbon nanotube material performed even better with far less fracture rates.

Wind Farms Off the Coast of Rhode Island Could Generate 1,000 GW of Electricity


Secretary Ken Salazar made an appearance in Rhode Island today to announce that the Federal government was accepting applications for offshore wind farm projects off the coast of the state and visit web site sale levitra that it would start signing offshore leases for those projects by 2012.

Rhode Island is getting special attention because of the huge potential for offshore wind in the state.  Salazar pointed to an NREL study that found that Rhode Island offshore wind farms could potentially generate 1,000 gigawatts of electricity -- enough to cialis discount prices power most of seyonic.com the U.S.

The state has already announced plans for a couple of offshore projects:  one is www.adime.es a smaller wind farm that will power the currently diesel-generator-dependent Block Island and feed any excess power to the mainland and the other is the generic viagra fedex huge 1,000 MW Deepwater Wind Energy Center that will be located in the Rhode Island Sound with transmission lines running from Massachusetts to New York.

With the government pledging to start signing offshore leases and the wealth of electricity that could be generated, there will likely be more cropping up soon.

Iowa Now Gets 20% of Its Electricity from Wind


Iowa has hit a pretty big milestone in wind energy generation -- the state now gets 20 percent of its electricity from wind power.  That's the highest percentage for any state in the U.S. and about on use levitra par with wind heavy nations like Denmark.

The American Wind Energy Association (AWEA) reported that the state hit the mark in the second quarter of the year after a new 594 MW wind farm came online outside of Adair.  The even better news is that Des Moines utility company MidAmerican Energy has two more big projects like it on the way in 2011.

With 4,000 MW, Iowa is second in total installed wind power capacity after Texas, which has 9,000 MW.  The Lone Star state's much larger population means that capacity doesn't stack up the same percentage-wise though.

The great lesson from this is that if Iowa can get to 20 percent wind power, any state can, and it looks like we're moving in that direction.  The AWEA reported that as of the beginning of viagra 100 July, 7,354 MW of new wind power was under construction in the U.S.
