- Mach5, on 11/08/2007, -0/+49I found the price:
2kw Low Wind: $8,500
2kw Medium Wind: $6,500
5kw: $16,500
does not include shipping/installation. - rsampaio, on 11/06/2007, -0/+24Why is it so hard to find out the price on these things?
- iching, on 11/06/2007, -2/+17Very beautiful design, I thought I was looking at a mobile art piece at first. Price?
- chandler, on 11/06/2007, -0/+13I'm wondering how hard it'd be to DIY.
- aargh01, on 11/06/2007, -1/+13I like the comment after the article about the aesthetic making it suitable for use on lampposts in cities. Might not be the best for everywhere (downtown areas and such), but they'd probably fit right in on waterfront parkways, giving them optimal wind conditions and less likelihood of vandalism. Plus, since they're safe for birds (I guess cause of the solid profile?) you won't be waking through the park and all of sudden half a seagull hits you in the head.
- DarkMeld, on 11/06/2007, -0/+12So lets say half of that is covered by state rebates $4250
My power bill is around $120 a month so lets say $60 dollars saved per month meaning around 6 years until the turbine breaks even. and thats in optimal conditions when your bill can be cut in half. - Subterfug, on 11/06/2007, -2/+12So basically, it's not affordable at all - contrary to the video. Thanks for posting the prices though.
- fotoman, on 11/06/2007, -1/+9CA rebates are $2.50/kw up to the first 7.5kW. So, $5,000 back on a 2kW system and $12,500 on a 5kW system
- jabab, on 11/06/2007, -0/+7Because they're so expensive.
- DiScDuCe, on 11/06/2007, -0/+6there are lots of state rebates and incentives that can really bring down the cost http://www.dsireusa.org/summarytables/index.cfm?Cu ...
- elnerdo, on 11/06/2007, -0/+6"A new twist on an old idea"
They have genius marketing people! - troymcdavis, on 11/06/2007, -0/+5http://www.instructables.com/id/DIY-1000-watt-wind ...
- Evildudetx, on 11/06/2007, -2/+6STFU about Ron Paul already.
- BobTrips, on 11/06/2007, -0/+4Just how many hours per day do you spend drying your hair?
- bradcrc, on 11/06/2007, -2/+5should be standard on every house. hopefully within a few years.
just like everything else, wide use drops prices.
who doesn't want to spend less on electric bills? - MikeWanDo, on 11/06/2007, -0/+3Like someone said in the comments on the page, I think this would work great in the downtown of a city on lampposts.
- inactive, on 11/06/2007, -1/+4Go to hell you spammer.
- bbcountach, on 11/06/2007, -0/+3the 2kw model is 6 feet tall! and the 5kw is 12 feet tall. the video makes it look like this tiny little 2 or 3 foot thing, but don't be fooled.
- silverchrysalis, on 11/06/2007, -0/+3well, you know what they say- if you hafta ask, you can't afford it. and seeing the post below, i would say that's close to true, at least for me.
- Berkana, on 11/06/2007, -1/+4It does look rather nice. Savonius turbines rock.
Now, if only Helix Wind's turbine comes with hot rod flames like their competitor's:
http://www.windside.com/ - Kronos6948, on 11/06/2007, -0/+2So, for those of us in apartments, we're still stuck. My landlord won't even let me install a dish. Imagine if I were to ask if I could install a 6 foot tall wind turbine???
- bbcountach, on 11/06/2007, -0/+2it's not meant to power your entire home, its supposed to help with powering. they never said "buy this and never pay for electricity again!" they said it can help reduce your electric bills.
- brad3378, on 11/06/2007, -0/+2I wonder if zoning laws would be an issue?
- sanman, on 11/06/2007, -0/+2Price is quoted at $16500
Hmm, the $Cdn is high right now -- maybe it's worth a purchase - ZenFountain, on 11/06/2007, -0/+2Looks nice, but I have to seriously question the 2kw rating.
- markp93, on 11/06/2007, -1/+3direct link to video -- http://www.youtube.com/watch?v=q9flSPAdOLk
- hydrodev, on 11/06/2007, -5/+6Thanks for the complete lack of info. Where can i get one? How much does it cost?
- republikdh, on 11/06/2007, -1/+2I read this as 'have'. And yes, it most definitely can.
- LanceUppercut, on 11/06/2007, -0/+1I have room. I could probably put 5 of these in my yard.
Unfortunately I don't have much in the way of persistent winds like they have in hawaii, so I don't know if it would be worth doing. - Neewom, on 11/06/2007, -0/+1If you goto the fact sheets on the web site it will give you the prices and the data to backup their claims.
- Farticus, on 07/24/2008, -0/+1No they are just typical marketing people, pathological liars. They stole the idea which has been around since at least 1979!! http://www.windside.com/windside.html
- quakerorts, on 11/06/2007, -0/+1Company website:
http://www.helixwind.com/en/ - jdm0778, on 11/06/2007, -2/+3I thought the picture was moving, too. Maybe I'm just hallucinating...
- DavidYeah, on 11/06/2007, -0/+1I think there are already renewable energy tax breaks. I certainly think we should advocate tax credits as well. We need to build the clean energy industry ASAP.
- dialtone, on 01/01/2008, -0/+1yes this unit is expensive now, so were the first cars & p.c.'s; with mass production prices would drop; just imagine the inter states lined with these things, or every corner of every building, parking lot/garage in every downtown, or every corner of every building in every shopping mall; economy of scale; every new house required to have at least one - built into the 30 year mortgage - the possibilities are endless
- wil2200, on 11/06/2007, -0/+1actually I don't know if these guys came up with this first, but on EcoTech a few months ago (DiscoveryScience) someone already demonstrated this concept, using the the DNA helix as the blue print and that one can also lay sideways - I hope that costs for all these new clean energy sources start going down more
- Evildudetx, on 11/06/2007, -0/+1Looks neat, but still overpriced for most households. I also don't see getting it past any home owner's association. They really hate things like this.
- greevar, on 11/07/2007, -0/+1I see I made a typo. "more efficient THAN"
- epalla, on 11/06/2007, -0/+1wow, instructables is a really cool site. How have I never seen it before.
- buzneg, on 11/06/2007, -0/+1When they say a "2kw turbine" that's just the maximum output of the generator. Large industrial turbines are built to run at about 33% of their rated generator capacity. This it to be economical, balancing the cost of the blades with the cost of the generator, because wind doesn't always blow the same speed. So a 1.5mw turbine would only put out 500kw/h on average, throughout the year. This 2kw helix likely only puts out .666-.9kw/h on average.
- NSResponder, on 11/06/2007, -1/+1If you're living in a place where there's an HOA to veto your decisions, you're probably too densely packed to get any benefit from wind power in the first place.
-jcr - greevar, on 11/06/2007, -2/+2I hope the government takes up some of the cost in lieu of reducing dependency on fossil fuels. It's also more efficient transferring power across miles of power lines. They lose energy the farther they go, which is wasteful.
- HappyScrappy, on 11/06/2007, -1/+1No freaking way. it's not going to generate that much power.
- foodbar, on 11/06/2007, -0/+0None of this is going to work unless it is available at Walmart and Target.
And, it needs to be pluggable. You use it like a power strip, between wall and appliance (or between utility and building). It provides power while it can, sucks from the grid when it can't. - bbcountach, on 11/06/2007, -2/+2i've never seen this many replies to a reply before!
- nedwin05, on 03/19/2008, -0/+0I wonder if the people questioning the payback of this thing worry about the 'payback' of everything else they purchase?
- vortice, on 11/21/2007, -0/+0One thing you're not considering: It is not only the turbine you need but also a system to store the electricity it makes when the wind blows and to convert to AC for use. That of course adds considerably to the cost but it means you're not limited to the rating of the turbine for your uses.
- bngeodesic, on 06/26/2008, -0/+0You could have 10 or 20 on a small roof top. The sky is the limit, or as long as a pipe pole can go!
- psimulus, on 09/04/2008, -0/+0The Helix Turbine is derived from the Archimedian screw and Da'Vincis artistiic renderings of flying machina. The Helix Turbine incorporates within its design symbolic elements that have been significant since ancient times. These elements include the Yin-Yang, Hour glass, Caduceus, Lemniscate, Vesica Pisces or Mandela, the Mobius, as well as other geometric constructs of significance. Archimedes screw posesses a center shaft, the H.T. does not. Archimedes screw operates using one functional reciprocating plane, the H.T. uses both and is in equilibrium. This turbine is housed within a cylinder so as to produce directional thrust and compression. This cylinder sits within another cylinder so as to provide a surface for rotation. This device has multiple configurations. I will describe its base configuration. Viewed from the front one would see a Yin-Yang. Viewed from the side one may see various geometric distributions dependent upon its angle of rotation. One shape resmbles a "claw or Talon" for lack of more definitive terms. Though the devices primary function is as a fluid turbine, it also exhibits some interesting optical/reflective properties. I have proven that this device has applications in the fields of propulsion and power generation. I have yet to determine the mathematical values associated. I hypothesize that it may also be used for compression as well as other applications. The device could also be caused to rotate via magnetic induction. This is to say that if constructed of the proper materials, it could be caused to rotate when in the presense of a magnetic field. I am not implying implicitly that this is a perpetual motion device, though I am making the claim that it deserves to be investigated. It can be constructed to operate similar to existing electromagnetic or mechanical motors.
So that others may be aware, I have been developing this device for at least 10 yrs independently. It can also be used for propulsion and can be constructed as an electrical motor. Their design is flawed. You can build your own for less than 1,000 dollars U.S. - HomeTurbine, on 10/18/2009, -0/+0Helix does not have the patented rooftop mounting that was invented by WindEnergy7. So their ARE and Helix systems will be prone to turbine vibration that will cause noise and structural vibration. Maybe they will buy WindEnergy7 next because without that patented roof mounting technology nobody can compete easily with WindEnergy7 for the home wind turbine market in the US. Helix also have no wind/solar hybrid technology making their systems completely reliant on wind conditions. I think WindEnergy7 has installed base all across the US now and I read has been exporting to other countries already. I think all these small wind turbines are really neat, we are seeing the future of residential energy.
I read about this over on inhabitant.com, a guy posts:
"I spoke to the owner and she showed me their loggs over the past 2 weeks (it just got hooked up). The highest day was 19 kwh with an average of 10-11! That’s maybe 4,000 kwh/year based on those numbers and these are windy Spring numbers so we’re talking probably something closer to 3,000 kwh/yr! That BLOWS for a $30k, 5 kw rated machine! Needless to say I was VERY unimpressed and would NEVER but one of these based on what I saw today.
I would look at the systems at http://windenergy7.com because they are proven and already have an installed base all across the US. -
