Solar Aero's Bladeless Wind Turbine

Solaraero-tesla

A research company in New Hampshire recently announced the patent of their bladeless wind turbine, which is based on a patent issued to Nikola Tesla in 1913. The Fuller Wind Turbine developed by Solar Aero has only one rotating part, the turbine-driveshaft. The entire assembly is contained inside a housing, so that this turbine offers several advantages versus blade-style (primarily horizontal-axis type) turbines. With a screened inlet and buy viagra in france outlet, this turbine does not present a danger to wildlife such as bats and birds. To an outside observer, the only movement visible is the entire turbine housing as it adjusts to track the wind. This also makes it a good candidate for use near military surveillance and radar installations, where moving blades would otherwise cause difficulties.

According to how much is levitra the company, the turbine is expected to deliver power at a cost comparable to coal-fired power plants. Total operating costs over the lifetime of the buy branded levitra unit are expected to be about $0.12/kWh. The turbine also should have fewer maintenance requirements, leading to lower lifetime operating costs. The turbine itself can also be supported on magnetic bearings, and all of buy tramadol cheap online the generating equipment kept at ground level, which will also make maintenance easier. The company estimates "final costs will be about $1.50/watt rated output, or roughly 2/3 the cost of comparable bladed units."

The Tesla turbine operates using the viscous flow of a fluid to move the turbine and thereby produce energy. The Tesla turbine "consists of a set of smooth disks, with nozzles applying a moving gas to the edge of the disk. The gases drag on ojalafilms.com the disk by means of viscosity and the adhesion of viagra 100 the surface layer of the gas. As the gas slows and adds energy to the disks, it spirals in to visit web site cialis fast delivery the center exhaust. Since the rotor has no projections, it is very sturdy." Disks in the turbine need to be closely spaced in order to capture the visit web site viagra on line viscous flow,. In order to be effective, the Tesla turbine also needs to have extremely thin disks to minimize turbulence at the edges. Tesla was not able to find metals of sufficient quality to make this work effectively, but apparently, nearly a century later, those limitations have been overcome.

Solar Aero's current example is an unassuming trailer-mounted unit, but a unit the size of the one pictured (see website) "should be capable of 10kW output with no problem," according to tramadol no prescription overnight the inventor. The number of disks determines the amount of power that can be produced. It will be interesting to see if this technology takes off, and if the technology is order cialis in canada something that can be scaled up to provide utility level power production, or if it is only a niche system. In any case, it is interesting to see alternatives to bladed wind turbines.

They need to post a computer model video on how this contraption works... that would lead to sales. Also, would be nice to see a wind speed vs. power output graph.

Interesting...

Granted I am not an engineer of viagra how much any kind, but why don't they install solar panels on the blade wind mills. There is obviously extra cost in doing that, but more electricity would be generated.

Cool! I think this is really great for birds and bats! I wonder if there is any information on the amount of space these take up compared to the current turbines. Are they the same size? Do they require the same amount of land per turbine? But definitely a step in the right direction. I hope they are made available to developers sooner rather than later.

Tesla does it again! smilies/grin.gif I agree -- an animation would go far to educate the click now levitra overnight delivery masses... and probably boost sales. Would be interesting to see a comparison of the unit shown at EcoGeek versus... whatever sized monster it would take to be 'equivalent' in output.

A picture or drawing of whole machine would be nice
written by Matt, May 04, 2010
Will I glad to see another approach being taken, but the web site contains no meat.

The Tesla turbine was design for steam, as the 1965 PM artical shows a power company build a 2ft-2ft-3ft model used 120psi steam and where can i buy ultram online got 200 horse power.

I guess they plan to put a big housing, say the size of large turbine blades in front of this and channel the air into the opening. So will you will not have the "noise" of a large wind turbine, it likely going to http://roguelephant.com/viagra-overnight have a bigger visual impact. If that is the case not sure how much safer it is for birds and bats.

How many watts per square meter cross section? 10kW?
written by Carl Hage, May 04, 2010
The unit pictured looks like it has about a 1 square meter opening. A 20mph wind has .6kW of energy, and about 20% conversion is typical (some as high as 40%), or about 120W. The claim of 10kW for a unit this size is about 2 orders of magnitude more than expected-- independent of the kind of online viagra prescriptions machine.

Compare that to a 100m diameter turbine-- the same calculations would estimate a power of about 1MW, just about what they are. The reason they have giant blades, is to get a large cross section, and so enough power to pay for the http://www.markwellgroup.com.au/cheap-viagra-pills thing.

@Sarah - it is dangerous to insects apart from nonsense
written by Mary, May 05, 2010
This machine will have rotating parts which spin so fast that they would be a danger to smaller flying creatures like insects.

The machine is cialis one a day too small to generate much power. I think it is BS in search of VC.

Another turbine idea
written by mkass, May 05, 2010
Here's another take on the idea of a wind turbine. (I am a total fan of ideas by Tesla, though.) http://organicconnectmag.com/w...an-energy/

@Mary For the most part we can only hope for less environmental impact, not zero.

There are little airfoils between the disks, out at the edge, which give it the push. pic here http://www.physorg.com/news192426996.html
Cool idea, hope it can scale up.

The disks turn both ways at the same time?

I'm sheptical
written by Jon Starbuck, May 13, 2010
I'm sceptical, it does not look like very efficient. I'd like to see test data over a range of wind speeds.

Skeptical too.
written by Brainjack, May 30, 2010
Not buying this concept at all. Doing similar math as others, but in the end ask how much power output would there be at an efficient wind speed? (a reliable speed)...100-200W? that's hardly worth it.

I wonder with some 'design blogs' that it's more about art and mental stimulation then reliable engineered prototypes. That's NOT ok though, as it's implied that what you see is factual. or the next 'revolution'

Can the original steam version be adapted to http://vizuka.com/buy-viagra-online-without-a-prescription run on steam radiators in homes located in cold-weather climates. It could generate power off steam generated: one from the radiator heat and the other for electricity. This would only be used in cold weather, but it since no additional energy is being used to generate steam for the turbine, it would be off incremental benefit, no?

Not buying it.....

This is one of those scams similar to "Better World Technologies" Playing off of online levitra Tesla's Cache they try and lure the buy cialis online canada uninitiated into "investing". I just think it is a crime these "news" outlets don't have someone with a little science and engineering background that can see through the BS or at least ask the obvious questions before giving these crooks so much free advertising.

Tesla turbines work great at relatively high fluid pressures. Something very difficult to achieve from the wind. Perhaps you could achieve the pressures necessary form an extensive and complicated venturi.
My question is why the reporter didn't ask the relatively obvious questions. I guess reprinting press releases is as good as journalism gets these days. smilies/sad.gif

We've been working on a Tesla Turbine running on 90% H2O2
written by Kris, August 29, 2011
To make a wind turbine like this the materials would have to be super light and good sized. We use 440 Stainless plates and the entire turbine plate we have, which is 17.75in. D, weighs in at 180lbs. You'd have to have a ton of wind to get this moving. Take a look at http://www.seabirdadventure.co...-different and let me know what you all think...?

This wind turbine design could really work
written by Wind Option, January 07, 2012
As you can see on my blog we focus only on wind power. I have recently studied about the bladeless wind turbine and it could really work. I'll try to build one at home and I will come back to let you know how I built it.
