you dont need $36,000 to build the prototype
all you need is a barbecue grill and a welding torch
one draw back it that it’s dependent on wind direction….
Hey, check out my website at ScientificallyGreener(Dot) com and get all the new and improved Equipments to build or buy your own solar and wind energy systems ScientificallyGreener(Dot) com is a website that sells the most modern environmental products available
might be a good idea to use a plastic drum to, might cut down on weight.
In its current form, there is no attachment shown to any generator. This prototype is little more than a moving lawn ornament and very fragile looking. I wonder what type of noise levels the homeowner will hear when there are high winds and a generator is hooked up. I hope the ridge vent is well isolated from the noise of the final product.
as fast as this thing rotates, u may power a single lamp with 5 of them
fail
no way 5 of those will power a home.
ppl i wnt to spain for 2 weeks and solar panels powered the house and the first night we ran out of electricity and your telling me 5 of those things are gona power a house….yes maybe if you put the tv into a rashans table…
Cool idea. The system pictured would only work in two directions. You need to harness wind in any direction right?
at night theres no sun to powersolar panels ,so foiled attempt at discrediting. And all these ideas rely on batteries to store the energy therfore should be under research and development
Your local “inventor” reinvented a Darrieus wing lift VAWT. Would be nice to give Darrieus a little credit. “The [Darrieus] turbine consists of a number of aerofoils usually–but not always–vertically mounted on a rotating shaft or framework. This design of wind turbine was patented by Georges Jean Marie Darrieus, a French aeronautical engineer in 1931.”

That’s true but there’s still no implementation to commercial wind power of any such designs. Any thoughts on why such a design with so many variations over the years but none succeeded the horizontal three blade design.
This is so cheap, it’s perfect! And just wait and se. Even more amazingly cheap efficient tech is on the way ^^
Even if it powered half the household power usage, it’s still a good thing. I don’t think anyone would be prepared to remove their connection from the grid.
Why not in vertical position? Crazy…
Cut your jibber jabber i ain’t gettin on no plane…
Great idea!
$700 for one of these!?! WOW RIP OFF i can make one for probably like $30 just no motor witch wont cost $670
The best concentration wind for a rooftop wind turbine is about 4 feet off the peak. So, there is much concentrated wind power that will go over this unit. Still, it’s a better idea than vertical because vertical turbines have that backside resistance, as one side catches wind, the other is resisting wind..
Renewable energy will capture a significant share of the world energy market over the next 20 year. The Department of Energy estimated that wind could account for 20% of U.S. power by 2030. Hence companies like Pacific Crest Transformers work with the wind energy sector. It offers various products for wind energy which include Grounding transformers, Wind Turbine Step-Up Transformers, Collector Step-Up Transformers, Dynamic VAR Compensation Systems Transformers.
Is that David Bowie? Aha… But seriously, they are a good idea. However, I don’t know that installing 5 of them on a roof would go down so well.
@SmallWindTurbines
There have been many many attempts to commercialize these types of designs. The problem is that they are so inefficient that HAWT’s crush them performance wise. If one does any research on the subject the reasons are painfully apparent. Sorry for the bad news. Don’t shoot the messenger.
Yeah but this particular turbine design is probably VAWT because it works in conjunction with being on a roof top. although I would only use a VAWT Horizontal-Axis Wind Turbine in places were the wind changes direction a lot so not sure why it has to be put riight on their roofs close to the serface, maybe it is a law were they can’t have something too high in the air who knows.
Those suits didn’t look really happy about the whole thing. Remember the big energy industry doesn’t like competition, especially when people can have it for almost free. Dont sell it to the gov., you’ll never see it on the market. Good luck and congratulations!
A government ‘incentive’ is so that the gov. knows who has a turbine so they can tax them for it. Gov. is not out to help anyone but themselves. Be wary.
