The Easiest Wind Generator You'll Ever Make

[@eknott1000]

Great video! I worked with small wind generators for a number of years. I noticed a stress point, on the way the blades are mounted to the plastic fan blades, over time the original blades will stress crack and fail. If you ad a blade brace to tie in all four blades on the front side of the blades, you will eliminate much of the stress on the original fan and give your windmill more longevity! Ed

[@robertwoodliff2536]

I was thinking about that, 'cos these things are built to a price. My perception is even a small diameter secondary disc / "washer" the size of the original fan , would help reduce the flex / stress on the fan root..

[@Nevir202]

Ya, I was thinking the same'. Those radiator fan blades always look like they may explode at any moment after a decade on a car under normal use, can't imagine how much worse the stress is when doing something like this lol.

[@georgesvideos6837]

If you actually add a cone to the nose of the blade that covers 20% of the blade surface you reduce the stress on the blades and increase the efficiency of the whole system because it reduces the drag.

[@Jim-re3sr]

Great video the motor should be water resistant since it was subjected to some spray sitting behind the radiator

[@mikearchibald744]

I love these videos and love the comments even more. Learning really is a communal experience. For 'free', and if you have some time, you can find online where people carve the blades just out of scrap wood. Some wood blades have been known to outlive some metal ones. I'm going to remember that about the washers and cone. I have a neighbour with quite a junk collection, I mean 'stuff' collection, I'm going to go looking for fans.

I'm female, older, still working, and am limited in both financial resources and time. I watch a LOT of KZbin vids on how to make projects simply, inexpensively, and that save me time. Your vids are always spot on and simple. So they are my first go to when I am looking for a solution. I love your shop! I agree with another comment, you need a companion video on how to mount this, and I would add, your simple windmill needs a tail so it can turn with the wind, as well as an easy to use breaking mechanism for when there's too much wind. Would be interested in a vid on these things too. Thanks for your videos! I'm a huge fan, excuse the pun!

[@GaisaSanktejo]

Small heads up for anyone making these: BROWN soil pipe is prone to deteriorating when exposed to UV light, so if you have to use brown soil pipe, I would suggest painting it or using some kind of UV inhibitor Modern black, grey or white soil pipe, on the other hand, is UV resistant 😉

[@Johny40Se7en]

[@montumeroe9593]

[@johnh9748]

This depends on the location. White pipe is normally NOT UV resistant in North America.

@@johnh9748 Fair enough, then wherever you hail from, you need to be sure the plastic is UV resistant :P

[@azizsetyawan3038]

Who cares. It's cheap anyway

[@leifhietala8074]

That was actually pretty awesome. I never considered the fact that there are HUNDREDS of inexpensive but robust, long-lived DC motors that can just as easily become stout little generators just hanging out at the Pull-A-Part. And some of them are even kind of big, larger units for cooling larger pickups and SUVs.

[@batbee7427]

Good point that some might not even need to be upscaled. Especially in high wind environments.

[@RobMacKendrick]

Years ago I was teaching in a remote school on a small island in the North Pacific. One of my students built a wind turbine much like this one, except he used a car alternator to generate the power and whittled 4-foot blades out of 2x4s. He mounted it on a 20-foot pole outside the school shop, and when word got round (tiny school) that he was ready to raise it we all turned out to watch. The best description I can give is "terrifying". That 8' span instantly took the sea wind and the thing just started wamp-wamp-wamping like it would eat the world. Chris finally managed to stop the blades by turning them out of the wind (which meant he had to get up on a ladder right behind those freakin' whirling broadswords and push on the vane), but the concept was well-proven. I don't remember how much electricity he banked in the battery during that maiden run, but all who witnessed it undoubtedly remain impressed by the sheer power he'd harnessed.

[@robertwoodliff2536]

......the apprentices of BTH built one at the halls that they had outside Rugby, it had thin ply blades, which they perceived to getting close the the sound barrier.......the rain/hale of the storm delaminated it.

An improvement to this would be a dome shape on the end, so you can take advantage of the coanda effect to push some more wind to the widest parts of the blades. Also if you had rounded the ends out so they fit around the middle circle part + the dome on the end this would take the most advantage of coanda effect I think

Rob, I love the idea, simple but very effective. May I recommend using grey soil pipe, the brown is for in ground use only as it does not like UV light, hence, it will fade and eventually crack if used outdoors. The grey will do the same job and can withstand the UV light. Keep up the great ideas.

[@MasterFloTechnology]

I was going to say the exact same thing. UV light will kill the blades in a year. I would recommend painting with UV reflective paint. The hub also looks like PVC.

[@Jiggledance]

Make like 10 of them using a Rose blade, various sizes down to a Rose Bud, and mount it on a windward wall. Paint them the color of flowers with different color patterns or different pinwheel patterns and colors. If it is too windy sometimes, add shrouds mounted separately that can automatically pop up in high winds and redirect some of the wind. Shape and paint the pop-up shrouds like giant leaves. The blades will still turn but shrouds will protect it from blowing apart. Just use a simple lever that has tension to hold shrouds down at low winds and high winds pry them up. Once wind goes down the shrouds go back in place. You can even design the shrouds to look like pedals that close and cover up the blade assembly.

Two hints for drafting the lines out for cutting the pipe up. Got these from years of making high powered rockets. Wrap a strip of paper a few inches wide around the perimeter of the pipe, the exact width is not important. Wrap it around once tightly and cut it so it just overlaps and tape it, so you have a band around the pipe. Hold the pipe up in a door jamb and trace a straight line across the paper and cut it. Fold the paper exactly in half and crease it. Do it a second time. Wrap the paper back around the pipe and tape it. Now line one of the creases up in a door jamb and draft out that line. Do the same with the other three. This is pretty common for spacing rocket fins. How much power were you able to get out of it? I am guessing under 50W. Not bad if you can get the fan for free.

Nice idea. Now, my concern is, that probably the cheapest way to store the power, is using car batteries. But I put four of them in series, when I was 14, to make an arch welding setup. It operated intermittently successfully for perhaps a minute. However, during the high current discharge, the batteries had created very large quantities of hydrogen gas, which I didn't think of. Also, I had severely underestimated how thick the wiring needed to be. (I musn't ever have seen car jumper cables?!) The wires melted and somehow, some small spark was created, igniting the hydrogen gas outside and inside the the car batteries, causing two of of them to violently explode and hurling shattered batteryparts through the air, and presumably also acid. Perhaps luckily, I had my back turned at the explosion. In conclusion, I since then carry great respect and awareness of the dangers associated with car batteries. Indeed any high capacity battery. And I feel hesitant to build a huge powerbank with them. It would have to sit in another shack / building away from my house. And then I would still feel I lived close to a minor bomb.,

Nowadays there are LiFePo4 and LTO type batteries. That's a lot safer. Of course, a BMS is used here. And no, they are not really more expensive when you calculate the number of cycles and the service life. (Not to be confused with Li-Ion!)

[@Inverted.surfer]

Hi there, just a little something I learned while restoring old batteries. The extent of the battery exploding depends on the how much water is in your battery. The more water, the less cavity, and less gas build up. Hope this makes sense.... All the best.

[@jlr3636]

At about 2:25 what you are marking the lines along the length of the pipe, a extremely easy way to do that is to use a piece of angle iron or aluminum, lay the angle on the pipe so both open edges touch and scribe the line, perfectly straight. Size of the angle doesn’t matter, 1”x1” or 3/4”x2” they all work.

I was looking for random ideas that may help the state I'm in they were having trouble supplying electric and heat to people for numerous months even through over the entire winter , were people tried to survive with no phone , and other ways of transportation they called it the home base program it started about 5 years ago here with certain people that did not want to be involved in it but were anyway. Thanks for another great idea

[@neagoecatalin879]

Nice concept, compliments! One mention, tough: the tips of the blades are perpendicular to the fan axis and if I'm right, those regions are not generating torque, instead are generating drag, isn't it? Maybe a bit more inclination on the blades would increase the efficiency and also help withstand better a roughly wind? What do you think? Thanks for the knowledge! Appreciated!

[@davidkatuin4527]

Well , simple and it works. That same design repeatedly tested and the results are that it works. Now how to design a more efficient working model. Maybe start with the blades. Thanks for the vid.

[@kaimcloughlin8981]

Very cool stuff, just curious what sort of wattage you got or what the current was at 20v? Keep up the good work 😃

[@simonpackham5780]

6:00 Cardboard box blown past in the opposite direction to where the generator is pointed. Awesome!

[@funkyfender1]

Robert, I wonder how it might work with a vertical drum style turbine? That would offer an omnidirectional presentation towards the wind without the need of slip rings or re-centring springs, wind vane and the need for counter weights and more critical levelling.... which would work well on a sailing boat... thoughts?

[@offroadflow]

if you get enough torque AND revolutions then any horizontal or vertical blade design works...

[@andrewchapman9931]

The problem with using drainage pipe is UV. Being used underground it will not have the same UV protection as the polymers used in above ground plastics and will breakdown and become brittle which could shatter. Good project overall. :)

[@carlschmiedeke151]

And yes i absolutely loved the video, & I'd a never thought of using an ol car cooling fan motor, brilliant

[@ft3917]

if you cut off some of the part very near the motor. the part that is almost vertical compared with the direction, it will be even more efficient. because so near the motor, the wind dont have much momentum in the turning direction. but the blade still moves arround, and have to push air to turn. if you look at factory wind turbine blades, they are not curved very near the motor. ( i am talking about the blades you put on.) that part they are streamlined round, for strength

[@kelvinsparks4651]

Excellent video as usual, though I think I'll give this project a miss . Although I could use the free energy, I'm dammed if I'm standing in the wind day and night to hold the thing up 🤣🤣🤣🤣🤣🤣

Just about to cut my blades now and I realized your fan is designed to spin clockwise and anti-clockwise to generate. Mine is the opposite. Glad I noticed that before I cut my blades similar to yours.

[@TheJMBon]

20 volts at how many amps though. You need the amp measurements to calculate watts. The a dc to ac converter to step up the voltage at the expense of amps.

[@pa_maj.MARTINI-van-MAN]

Or a DC to DC charge controller to charge a leisure battery. No need for an inverter if everything runs off 12 volts. You're 100% right about the amps produced at said voltage for anything really useful, I was hoping he'd have gave us that info at the end of the video too 👍

[@rogerpeters1630]

Exactly. Any nominal 12 V solar panel can create +20V open circuit too. The power it's able to generate varies with size of course. Put a load on it and watch the voltage drop. If the load is matched to the power rating of the source the voltage should stay stable at around 13-14 V or so. For example, a solar charge controller ensures that it only puts as much current into the batteries as it can while keeping the PV array voltage at around 14 V, enough to keep current flowing in the right direction.

[@glennandersson5993]

Talk about a simple solution. Thanks so much Robert Murray-Smith for a very good video

[@ElizabethGreene]

[@richardcarew4708]

Actually the only reason for AC is because we can send it long distance without loss of voltage, through transformers every couple of kilometers... Tesla's benefactor and sponsor JP MORGAN wanted to get even richer... and Edison pushed direct current as safer... it's a lot less energy... and doesn't travel well... it requires local production... within a couple square kilometers... at the turn of the century in 1900 it meant coal fired electric plants... each hectare... prox... that's no longer true... locally made DC is absolutely dandy for household use... even air conditioning here in Arizona... where it is currently about 45° C outside... it's a very low temperature for this time of year... solar radiation is at max around the solstice... and it is sometimes as much as 50°... half way to the boiling point of water So I am going to install a cooling tower in my garage.... a tapered tube open at the top... I am going to put a wind powered turbine on top to push air into the tube... with a misting system at the top... its cooling causes air to sink.... and, through the existing air conditioning vents, a 12 volt exhaust fan can draw cool air through the entire house... I am starting with a cardboard tube .. and shellac to create a biodegradable bio plastic... I don't use denatured alcohol for the shellac... I use acetone... it's much more polar and creates a very hard, durable, bio plastic... I add AuPt dust... from volcanic ash... or any stream, creek, river or dry wash... it's absolutely ubiquitous, and not hard to find... it's slightly magnetic... and when you collect the sand from wherever water flows naturally... it can be separated out with a good magnet... it's the only gold stuff that sticks to a magnet... ya can't miss it... dry wet sand... and they separate much more readily... the taper creates a vacuum at the top, but whatever velocity it has is reduced by some factor of pi r² as a function of the diameter... so I will draw cool air through smaller tubes... and the greater pressure in the tapered tube is pulled through at a higher velocity... it's a function of the 2 diameters and the ambient air pressure Adding a small amount of AuPt to the plastic creates the double covalent bonds, I think only one double covalent bond... and it crystallizes the paper into a semi metallic crystal, which can be baked at a couple hundred degrees C... it's almost, almost like the first plastic called bakelite.... it's 5.5 on the Moh's scale of hardness... the same as stainless steel.... with my homemade paper... it's actually stronger than steel by a wide margin... because I use silk on the surface to create a smooth... incredibly strong bio plastic... and instead of trying to get rich... I give my ideas away as fast as I can.... the Universe gives back exactly what you put in... and a little bit more... I have no shortage of new ideas... mostly using existing technology

[@richardcarew4708]

The use of fossil fuel is the only cause of global warming... and it is not our benevolent government's responsibility to ==>> give us ==>> different fuels... and I don't recommend holding your breath waiting for new fuels through government patents... those DO NOT "encourage new invention and technology"... it's exactly the opposite... it's very very expensive... it should not be done without a lawyer or two or three... and... if it looks like a viable technology... the cost of infrastructure to build whatever it is... usually comes from borrowing money. ... or money with strings attached... like old JP Morgan... and Nikola Tesla... and when you start making money.. they foreclose, or buy you out... and your nice invention... and your business then belongs to the money lenders... it's the same gawddamned money lenders mentioned by another teacher... it's not possible to borrow money from the oligarchs... and maintain a viable business... that's why very very few people get rich... quick or otherwise... it's always the offspring of other rich people who have access to funding without strings... it's a very very inbred group of people... they control all the resources of our lovely Planet... including, and especially, information Best bet... ==>> turn off the gawddamned television... it's not accurate information.... and they have controlled our Planet since long before the KT extinction event...

you can get really good propellers from the pipe if you cut them correctly. and is really efficient compared to any vertical turbine
