Wind Power

Electricty Generating Jersey Barriers

Stand near a busy roadway and you'll be buffeted by gusts of only today buy cheap generic levitra wind as cars pass by. The majority of energy used in highway transportation goes to move huge volumes of air out of the way of our vehicles, not moving the vehicles themselves. So why not harness that energy and make it something useful?

That was the levitra prescription thought of Mark Oberholzer, who proposes installing small vertical-axis wind turbines inside 'Jersey barrier' highway dividers to drive electrical generation. "Opposing streams of traffic create really incredible potential in terms of a guaranteed wind source," Oberholzer says.

This is an idea that is enter site buy levitra from china still under development, but one proposed application would be to install these barriers in conjunction with a light rail system running in the median of the highway. "I love the idea of siphoning off electricity generated by private transportation to cheapest generic viagra online run public transportation." Using the power where it’s generated, rather than redistributing it through the grid, avoids energy losses that occur during transportation and eliminates the cost of adding extra infrastructure."

Miniturbines Combine their Power

Urban turbines are no simple matter. To really pull a good amount of power from the wind, it helps to have a turbine with a fairly large diameter, and to have a big turbine, you need a big plot of land.

Unfortunately, most of us just don't have huge...tracts of land. The solution, however, may soon be within reach with the help of modular wind turbines. While other small wind turbines we've featured have decreased the footprint considerably, these modular turbines can fit just about anywhere, be arranged into any shape, and can pull power from the air even in very low-wind environments. Wind speeds as slow as 2 m/s will start the juice flowing.

The miniturbines are already for sale, but it looks to me like mass production could easily bring down the price considerably (from $150 for 8 miniturbines.) But even now, only one square meter of buy viagra online at miniturbines will produce 131 kw/yr in a 5 m/s wind environment. Most houses, though  will be able to find quite a bit more than 1 square meter, and in higher wind areas, these little guys could easily shave hundreds off home energy bils with a truly simple and elegant design that won't even disturb the neighbors.

Windturbines for Carbon Sequestration

Last week at an American Physical Society meeting, an organization of entrepenuers and university researchers released the their first round of plans to create windmills that would scrub carbon dioxide from the atmosphere.

These devices, powered entirely by the wind, would extract carbon dioxide from the atmosphere and then store it in some kind of physical substrate. The details of the plan are completely under wraps, and the how to buy ultram official announcement of the plan won't come for a while yet. But our friends over at Environmental Research Web got the scoop (reg. req'd.)

The costs of this carbon sequestration project are also extremely fuzzy, but the researchers have said that the devices could make the world entirely carbon neutral by spending the equivalent of levitra for cheap 25 cents extra per gallon of gas. We're taking all of this with a grain of salt, but nonetheless, we're excited for the official announcement.

Spinning Blimp Wind Turbine

From Magenn power Inc comes an interesting new design for a wind turbine. This could be a goodyear for renewable energy. Called the follow link purchase of viagra 'M.A.R.S' - a fantastic acronym for the Magenn Power Air Rotor System - which promises lower costs, better performance, and enhanced environmental benefit. The turbine is a lighter than air blimp, which rotates around a horizontal axis. A unique design orients the blimp into the wind. One of the interesting facets of this technology, is that as it is anchored to the ground by a 1000 foot cable, the MARS could be anywhere up to generic propecia alternative 707 ft from its base.

The MARS blimp will come in a variety of sizes. First, in small applications that will produce around four kilowatts of power at roughly 20 cents per kilowatt. These, obviously, are useful only in off-grid situations. However, Magenn plans to create much larger MARS turbines that will produce up to 2000 kw per turbine (twice that of the world's largest wind turbines.) These would likely be cost effective in wind farms and, if implemented correctly, could even be combined with today's current farms.

This device is higher than your average turbine, but lower than other tethered turbines we've seen. Thus, you can neither see nor hear the MARS turbine, and it is able to harness unobstructed higher-altitude wind currents. But, unlike some kite- turbines that we've seen, the MARS turbine won't interfere with commercial air traffic any more than cell tower would.

We see a lot of potential for these blimp turbines in the future of wind power, and we'll be following Magenn closely in the coming months.


Short and levitra without prescription Stubby Turbine puts out 1,100 kWh/month

{mosimage}Here's a small (4 foot tall by 4 foot diameter) vertical axis wind turbine designed for residential installation. According to the manufacturer, the Mag-Wind MW-1100 can generate 1100 kWh/month in a 13 mph average wind.

The short stance of the Mag-Wind turbine seems to provide an added benefit of enabling it to keep generating in extremely high winds. It can withstand a top wind speed of over 100 mph, where most other wind turbines have safeties to stop them if wind speeds get too high (some even as low as 40 mph or less). And, it is designed to capitalize on the effect of a sloped roof increasing the wind pressure to boost its efficiency (though how well that works probably depends on the orientation of link for you best online levitra the roof and the direction of the prevailing winds).

The company claims a faster payback than solar or a typical horizontal axis wind turbine, and a cost of only 3.5 cents per kWh.

I'm somewhat concerned about how well it would work in northern winters. If I had one on my house right now, I imagine it's wide base would be clogged with ice and snow. I'm also afraid many people will find it unattractive (and tellingly, the only image of what it would look like is an edited composition, rather than a photograph of an installed turbine). But, having a lower energy bill would certaily look good to where to get cialis cheap homeowners who will choose this option. And if it becomes popular, designers will certainly find ways to incorporate its look into new homes in the future.
