Everyone commenting that this can't be made for less than $30 please first read the materials section of the build tutorial: opensourcelowtech.org/wind_turbine.html
All the relevant information is there.
Facebook discussion group: facebook.com/groups/windturbinemakers/
This is the up to date build process for the OpenSourceLowTech.org $30 Lenz2 vertical axis wind turbine. The turbine can be made almost entirely from recycled materials with basic tools in six hours for $20-35. It is tested at 35-40% mechanically efficient, generates 130 watts mechanical in a 30 km/h wind, 1 kilowatt at 60 km/h, and can survive 100 km/h gusts.

What if the blades of turbines were also solar panels that generate electricity when the wind stops? Is that possible?

You can see they are suggesting used scrap as it has print on it. These can be picked up for free after a auction or electronic around here. Takes a lot of asking to find them but they can be acquired.

A lot of work with the graphics, but without a demonstration of it actually working and proof of it producing an adequate amount of electricity, it's pointless. That video at the end is not helpfull.

Outstanding CAD work/animation and overall design! Perhaps limited narration for "things to watch out for" at critical points in the build would make sense - but that's only a suggestion from someone with limited handyman skills. Quibbling over whether the device could be replicated for $30 is silly; I'll take those comments seriously when someone tries to replicate the materials purchase. I'm much more interested in the performance data. The prevailing wind in Richmond, Va averages only 6.2 mph. I'm much more interested in the performance data at varying wind speeds - as well as knowing the top wind speed that the device could likely withstand. All that said - great job. I'll watch for your solar hot water heater and other projects - if nothing else, I suspect they'll be entertaining.

@northavealum than it shouldn't read $30.00 .pretty simple really.
northavealum Month ago
So what if he didn't? Suppose it was $100 instead? Does that somehow invalidate the quality of the presentation and the engineering of the device? Was the $30 what captured people's interest? I doubt it. I was attracted by the notion of designing and building your own vertical wind turbine - and I think most people understand that dollar figures offered in these types of videos are estimates, not the sales price.
Christopher Polzin
How much does haviing three generators on one turbine increase the kilowatt output? And then with that array of staggered units, imagine three generators on one stack. What kind of wattage can you generate as a max per stack? And have you ran any tests under wind loads, etc?
Actually probably best to ignore that three generator configuration, it's turned out to not make a lot of sense in reality. I'll be updating the tutorial soon with some more tried and tested options.

it is possible to generate by combining water turbine and wind turbine and if possible so solar also.. how much electricity we can generate... the idea of combining is bcoz all the time we dont get everything.. we wont get sun everytime. we wont get wind everytime.. we wont get water forces everytime.. but if we can combine 3 of them it would be possible to get electircity maximum hours..
Randy Simpson

Unfortunately this is only half the battle. Once you generate that 1 kw what do you do with it. To incorporate it into your house you need all sorts of additional equipment. I have a Magnum Inverter on my motorhome to handle the solar panel among other things. It sells for $2,200. Then there is the safety equipment you have to have if you load share with the utility. And in some states the utilities are not required to buy back any excess power you generate. In fact where I live there is a surcharge on your normal rate if you have solar so you end up paying the utility for the electricity you generate. There are lots of really smart people in the world. If it were easy someone would have done it already. In the US there have been quite a number of individuals and couples who have tried to go off grid. A small few have made it by moving to tiny (400 sq. ft. or so) or huge expense (tens of thousands for solar or solar/wind and associated electronic controls). Most have given up as being impractical and just too damned much work babysitting the systems that normal people (not movie stars or politicians) can afford. Hydro power is off limits in the US, environmentalists go bat shit craze if you even bring up the idea. I had a stream in my back yard when I lived in GA. Did some research, found it would be impossible to do anything even though it was on my property due to state and federal regs around which there is no way and many thousands of dollars in fines and possible jail time. See for instance the CA couple who were fined $600,000 for moving (not cutting down) a tree on their own property. So yeah, if you live in a cabin in the woods, have no electric appliances other than a 100 watt light bulb and a phone charger you could, maybe get by with the so called 'green' sources.

One minor suggestion, if you ever render this again or to anyone building it, you should consider inverting the alternator / generator. It doesn't change any of th load on the bearings and will allow you to put a cap over it to keep the weather out.

Good video. Suggest since inherently a vertical can never get more than 50% (usually less) of the wind force available because it fights the wind coming around from the back: that you put regular horizontal axis w vanes, to maximize the energy available. I like the slow moving (SAFER) large vanes aka Dutch windmill w perhaps 30 ft vanes that furl up in high winds, etc.

@OpenSourceLowTech If you combine these stacks with windfunnel constructions and/or greenery you'd up the power production even with very little wind.

Yep. Generally with this design the pole etc costs more than the turbine, so having multiple turbines per pole effectively drops your cost per watt.

So.. @$.12 per hour, I'm looking at a payback in 250 hours. Labor @ $15 X 4hrs. equals $60 or another 500 hrs. Total payback time is 500 hrs. If output is 50% around the clock, that's 1000 hr. When that transpires, you will begin saving $.12 per hour, or six cents per hour if the output is 50% of the time.

The guy-wires alone would be more than $30 so this is misleading. The blades are $30-ish, the stand, guy-wires, and generator would be another price point entirely. The BOM on the website is only for the blades, not the full design shown in the animation.

In practice it's not been a problem. Longest running one of these so far showing no corrosion anywhere after three years in proper weather.
Les 6 months ago
Nice presentation, but it promises way too much power. To produce 1kW power from this device, the swept area (diameter x height) would have to be about 10 m2 - assuming a very generous efficiency of 30% and wind speed 10 m/s (22 mph). Not to piss on anyones's parade - neither the efficiency of this device is 30%, nor the size is even remotely close to what is needed. Nice presentation though.
Les 6 months ago
Well...I wish you all the best with this design - but this is similar to saying that a 1960 Volksvagen Beetle can reach speed of 250 mph - but only in free fall...The design is nice and simple, the presentation is great, just the expectations are too high.
OpenSourceLowTech 6 months ago
1 kilowatt is the maximum realistic output, not the nominal. More numbers are available in the build tutorial linked in the description.

and we still have low technology like yeeeeears ago and we cant evolve to free energy on every home. we could be so much further with the technology if it would be given to us. free energy on homes, free energy for cars.
facite non victimarum
Misleading. You need almost gale force winds to produce the *clickbait* 1 kilowatt output. Even 130 watts require 18.6 mph wind. And those are 'mechanical' outputs before the power generating inefficiencies. The 99% of the time you don't have those winds it's just a perch for birds. IIsn't anyone on RUvid honest?
facite non victimarum
@OpenSourceLowTech I've read the damn tutorial. It's both the tutorial and the tutor I question. Two people doing it is not "do it *yourself."* Two people for 4 hours is 8 man-hours. At minimum wage, at least $80 labor for construction *alone.* To study the instructions and to do the labor of simply gathering the materials and "scrap" which miraculously came from nowhere another $80 minimum. To actually acquire the materials and tools one doesn't miraculously have, another $100 *absolute minimum* for the labor involved, direct costs, and indirect costs. Most people would agree my ballpark estimates are closer to reality than yours. Show us some *average RUvidrs* who actually built one for $30. Where are the data for one or more actually installed showing wind speeds and power output? (Not wind tunnel tests.) At an "overstated" $30 a copy you should have several installed right? Ten of them from start to finished, built, installed and operating is only an overstated *$300* by your figures, less than the cost of the old used computer and printer required alone. Where are the ten you could very easily afford from YT views alone. I'll give you 100% profit to build and install 10 for me at $600 total. I'll add a 15% gratuity. What is this obsession with the $30 figure and the one kilowatt misleading half-truth? They're so obviously outrageous that it makes one question your motives or judgment (or, frankly, mental state). In other words, "Anyone who doesn't take truth seriously in small matters cannot be trusted in large ones either." - Albert Einstein I have no dog in the fight, just sick to death of all the bullshit on RUvid and the epidemic of alternative truths and realities (aka, fu**ing lies) pervasive from the top down in my country. It's officially legal to bullshit or lie now because everybody else does it openly and with impunity - especially our corrupt leaders - so we can too. No need to reply. Especially if you start off with, "Again, ..." Btdt
OpenSourceLowTech 6 months ago
Again, peak output, not nominal. There's no standard use case for wind, so nominal numbers are usually fairly useless. I give power outputs at various lower wind speeds in the tutorial. The output is based on wind tunnel testing, you can google Lenz2+wind+tunnel+tests to find them. The costs are accurate if not overstated. Again, this is all in the tutorial. The video is of it surviving 105 km/h for 15 seconds, which is more than a gust, and that's a much earlier version with the current build being about an order of magnitude stronger. The chain drive and three gennies setups are some that I've since abandoned for being not very good ideas, I'll be updating the tutorial in the next couple months with current better ones.
facite non victimarum
@OpenSourceLowTech I'm going by your numbers, the ones that get people to watch the video. Where do you have sustained winds at 37.3 mph to produce 1 kw? Remember this is DIY. Admit it, you're exaggerating the output and the ridiculously low cost. I'm a mechanical engineer and outputs aren't rated for extreme conditions. Stand up in the back of a pickup going 37mph and see what kind of sustained wind you would need. You said it could survive gusts of 100 kph (62.1 mph) yet another video shows it falling apart at those speeds. I'm not questioning the concept or that wind turbines can work, mostly just the numbers, but also the cost and the efficiency of that chain drive on the 3 generators or alternators. That said, good job and best wishes for further success.
