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.

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.

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.

You do *NOT* want aluminum and steel contacting each other exposed to the elements, galvanic corrosion will quickly degrade most of the structure

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.

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 3 месяца назад
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.

1 kilowatt is the maximum realistic output, not the nominal. More numbers are available in the build tutorial linked in the description.

facite non victimarum 3 месяца назад
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 3 месяца назад
+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 3 месяца назад
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.

+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.

Thanks for sharing this with us, this is spectacularly well-designed and presented. The instructions are thorough, with no personal presenter to distract--or entertain--us. I wonder what the efficiency would be of each design, but for only $ 30.00 a pop, you could put up a whole field or rooftop of these things and go off grid. Thanks again.
