Bird Groups and generic 40 mg levitra Wind Turbines Getting Along

It has been widely assumed for years that two groups that don't get along are wind power advocates and bird protection groups. But, in a move that shows how far things have come, the Royal Society for the Protection of cheap discount viagra Birds (RSPB) is looking at installing a wind turbine at its headquarters. The Society has applied to install a 100 meter (328 foot) tower for a wind turbine near its headquarters in Bedfordshire.

This is not a complete reversal on the very good site levitra online switzerland part of the RSPB, and there have been cases where the RSPB has objected to wind farms. But it shows how wrong the old stereotype is. The Society's perspective is that "renewable energy is an essential tool in the fight against climate change, which poses the largest threat to purchase viagra in budapest the long-term survival of birds and wildlife." Furthermore, they believe that, "so long as proper due diligence is conducted and potential wildlife impacts mitigated, ... developing wind power is a smart move."

More advanced understanding of bird migration patterns and habits has helped with the http://www.bsz-wurzen.de/buy-low-price-cialis placement of wind farms in places where bird fatalaties can be reduced. Other technologies that monitor bats and birds, and intermittent disabling of wind farms during migration periods also help to further reduce the numbers of animals killed by wind turbines. And, in terms of revistaneon.net numbers killed, buildings still remain a far greater threat to birds than wind turbines.

Wind Ship “Vindskip” Would Use Its Hull As a Sail

In another approach to improve cargo ship design using wind power, Lade AS has developed plans to construct a hybrid cargo ship. The Vindskip, (“wind ship” in Norwegian) would use its own hull to channel wind as a sail or airplane wing does. Powered partially by a natural-gas fired engine, the external design of the ship would generate lift to assist its forward movement. In order to travel in the most optimal conditions possible, Vindskip's systems would constantly calculate both the direction and speed of the wind. Using the “apparent wind” (the wind as moving objects experience it), Lade AS claims, these systems would allow Vindskip to the best choice buy pfizer viagra online have a positive pull at a minimum of 45 percent of its time en route, traveling at speeds of +16 knots.

The company estimates this design would reduce emissions by 80 percent and fuel costs by 60 percent. While a small model was tested at Cranfield University's wind tunnel with success, the projected efficiencies have yet to be tested at full scale.

In India, Cost of Wind Power Competes with New Coal

According to a recent report by HSBC Global Research, wind power has become cost competitive with new coal capacity in India. Solar is wow)) cialis sales uk not far behind; the report also claims it is likely to become cost competitive between 2016 and 2018.

While policies like the reinstatement of take viagra the Generation Based Incentive for wind power projects have made them more financially viable, as HSBC reports, this specific change in the relationship between wind power and coal-based power can be partially attributed to water shortages. In India, thermal power plants account for almost 90 percent of industrial water demand. Coal-fired power plants use significantly more water than renewables like wind and solar, and water shortages have been affecting coal-based power production in India during the past three years, causing some power plants to close partially during the pre-monsoon season.

India already ranked number five for global wind power capacity as of 2011. While improvements to the power grid infrastructure would be necessary to we like it levitra no rx required get new wind power generation sources linked to businesses and homes, this change in relative cost likely coincides with, and perhaps will directly cause, an increase of wind power projects in India. As the HSBC report states, “India currently has 1.2GW of installed solar capacity and over 4GW of capacity is at various stages of tariff bidding. We expect commissioning of selected projects within two years.”

First US Floating Turbine Launched

The first grid-connected floating wind turbine has been launched off the coast of Maine, moving the http://www.aumm.nl/cialis-professional-100-mg US forward in its deployment of offshore wind power. Offshore wind has been well developed, particularly in Europe. But, despite having extensive wind resources, the US has done very little until now in the way of establishing offshore wind power.

The VolturnUS turbine is actually only a 1:8 scale development model from the University of just try! buy branded cialis Maine Advanced Structures and Composites Center. Nonetheless, the structure is a 65 foot (19.8 meters) tall, and produces enough power that it can be tied to the grid.

This turbine will serve primarily for design study and data collection. According to the Department of Energy, the VolturUS "will collect data to validate and best way to take cialis improve floating wind turbine designs, while helping to address technical barriers to greater offshore wind cost reductions."

 

A Small Wind Turbine You Can Make Yourself

As the June 17 deadline to the Instructables Green Design Contest fast approaches, Jaymi Heimbuch at TreeHugger has highlighted one particular entry: a small DIY wind power generator that can sit in your backyard.

The wind generator’s designer, out-of-the-box, offers demo videos and text instructions accompanied by photos. As the designer notes, the amount of electricity the generator can produce depends on discount levitra cialis viagra the steper motor you choose to online levitra prescriptions use when constructing it yourself. The one shown in the instructions tops out at 8 volts, but on a still day outputs around 4. Modifying the turbine to increase efficiency, out-of-the-box is posting updates after the last step in the instructions, like removing a cup off of each arm to reduce wind resistance and adding unobtrusive solar panels.

This contest’s accessibility stands out among some other green design competitions. It doesn’t involve prototypes that use obscure materials or require years of experience in aerospace engineering. Instead, each entry must provide step by step instructions to show others how to make the project themselves.
