You almost need to put a disclaimer at the beginning of each video, "Caution: This video is meant to encourage creative thinking and resourcefulness and to inspire your own projects - NOT to achieve the best possible results. Those with tunnel-vision may experience confusion, agitation and/or nausea." If people approach your videos understanding they will be shown resources, materials, techniques and effects, they'll walk away with a wealth of information they can apply in countless ways in their lives. But if they approach it thinking they will find the "most efficient wind generator of all times" they'll walk away with severe disappointment, unless they actually bother to apply the various things you've shown them to invent one.
it often amazes me the extent to which folks seem to hope for an instant answer - and when the answer they get is you need to do some work - they do seem unhappy lol
@@ThinkingandTinkering I think the frustrating part of that is how much effort it took to learn things when we were younger. When I was a teen, I had to ride my bicycle about 10 miles or so to the nearest Radio Shack just to get my hands on a "machine language" manual. I couldn't afford to buy all the books I needed/wanted, so I'd have to read and study it there, go home and write out code, ride back to Radio Shack and painstakingly poke the code into memory on a display model TRS-80 to test it. I can only imagine what I could have accomplished as a teen with a $10 Arduino and RU-vid at my fingertips!!
@@ThinkingandTinkering if you look at other RU-vidrs, they demonstrate this wow of smoke and bangs and polished stuff to ENTERTAIN, not give a video in a direction of course for you to have a base line to build on. Big difference.
@@jeffreyrood8755 Right? You forgot to mention, other RU-vidrs also try to look like "perfect" fashion models on "perfect" sets, trying to have "perfect" outcomes. Real-life isn't like that. I think all that "perfection" is actually a harmful trend - it promotes unrealistic expectations. Creates harsh self-judgment in the viewer if they can't live up to what they see, it can discourage them. What I love about this channel is that it's completely down-to-earth, like you're working in the lab together with a colleague. No theater, only real life: "Just thought I'd share that with you, as I thought it was really cool." Real human collaboration toward a goal of mutual inspiration.
Many people I know would call you a "tweaker", but in reality you're just a courious man playing with bits and bobs to further your understanding. As a wise man once told me, "the day I stop learning, is the day I die." You sir, are living by those words. And I'm quite happy to sit and watch you do so when I'm not doing the same thing myself.
@@ThinkingandTinkering Perhaps adding a cone, like the last iteration, to this squirrel cage to help direct the wind through the blades would increase efficiency as well.
@richard mccann agreed the cone creates a pressure differential between the inside and outside edges of the cage. Larger cone. = Larger deadspace = greater air pressure torrential of wind in motion
Harvesting "micro" power is the future. Big power plants should/will feed factories. You,me and everyone else should look at ways to become energy independent. Not all in one shot. But piece by piece. Imagine your fan and a battery big enough to boil the water for your morning tea and eggs. If every houshold could do that, one of the powerplants in UK could be dedicated to industrial purposes. Thanks again for your inspiration.
I am a Brit, living in the middle of nowhere in the Ohio woods. I love it. I can do almost anything I want out here.....antennas, build decks, install fences, shoot cans in the back garden, cut down trees, etc.. I also hate asking permission.
I really like this I have several blower motors left over. I grab 1 or 2 everytime I hit the pull a part. Just the motor n fan. I take cardboard and foam board and build my own cage for them for shop fans etc. They run great off my solar.
Who cares what people think. You are having fun and taking us along for the ride. For that I thank you. Every thing you do give you a different idea that leads to something else. If in the end it all lands in the garbage( and I don’t think it will) we will have all learned something and had a good time with you. Thank you.
Looks wonderful... Very much enjoying the continuing theme. I live in Wyoming, US... The wind rarely is not blowing!! Great to see the cone, I had been considering quite the same, essentially large volume collector choked down to smaller concentrated application... Had been thinking of a megaphone, in general... Thank you so much, Robert!!
@@ThinkingandTinkering I had been considering a directional high volume collector, air flow to turbine of course... Thinking of incorporating a directional tail, or "rudder"...of course, would be a vertical collector for a horizontal "flat rotor"... I hope to play with it a bit... Sir Robert, I have looked and apparently missed, might you have an email address you prefer to use for a more direct contact and opportunity to discuss a notion or two?? In advance, thanks so much!!! Cheers...
You sir are what we call an "If It's Engineer" If it's there you can use it, If it ain't you can't. Please take it as a complement. As if I washed up on a desert island, I'd hope an If It's Engineer was among the survivors, because everyone's chances would increase a thousand fold.
Absolutely agree - the best fun is using what you've got, because it forces you to think, work out and learn, not just go out and spend money. I got some great bike wheels from a skip down the road, a bike repairer packing up his business - carbon rims and very nice bearings!! So, two bike wheels, cut tubes in half for blades, now I have to find a motor / generator.
I can’t believe people would write such comments, all you are doing is demonstrating different ways we could generate our own energy out of scrap!. I keep saying ‘I love this one’ to your vids, but this car heater motor generator is great, I was amazed how much difference the cone made to the rotation. I wonder if some ‘fins’ inside the cone to direct the wind into a vortex would make the cone more efficient?
Rob, you rock!! Wind energy, dry cell, artificial muscle, earth and all kind of batteries, capacitors and so on... please share your thoughts about a hydrogen internal combustion motor and keep on rocking.
The best time to plant a tree was thirty years ago. The second best time is today., The worst time is never. So I get a couple of watts with a unit you glued together in a tea break on Monday By the tea break on Friday that could be a kilowatt. I fail to see why any one would make comments like “it’s rubbish”. “It won’t work” “only a couple of micro amps. What’s the point in that?” You show far more patience on RU-vid than I would Robert. Fair play. We should start doing channel challenges. Doing and failures are the best teaching experiences going. I really like failure. Never far way at the start of any thing new.
Rob the idea is sound adding lots of small ones together but put them on an open fence or wire mesh. The wind has to go somewhere when it has turned the generator and with a wall it can only go up or sideways which would disturb the other generators. All good learning.
The cone works better, because, it shields the sides of the rotor, so the wind blowing through the cone into the squerl cage can flow away easier. With the cone you creeate a higher pressure difference between inflow and outflow. It also funnels more air, creating higher pressure at the inlet, so it serves 2 purposes. But i think the creation of a high and low pressure point is the main reason the cone works so well. Cheers, Rene
LOL I did the same thing with a Toyota blower rotor to check the effectiveness of the Water's design...was greatly impressed..still ended up building a savonius with a 55 gal barrel
-You have not achived, with hundreds of tests and costructions, what you want, and have in mind. -NO, I still have in mind, what I want, but now, I know "hundreds" of wrong way, to achive it. Carry on, invent, make the best you can, this is what is called "spirit of invention". Best regards from Brasil
An excellent design for wind energy. Your wall turbine and the funnel could be fitted inside a square box ( a Microwave casing could be used). With just a round hole on the side facing outwards, I can picture it now, like a small AC unit attached to the wall.
On top of the funnel [which I mention like every other video] it occurs to me that if you can create a relief duct around the rotor housing, one that shunts the wind to the far side of the house [need not be on the wall, can run along the ground or even work against a fence, any place where there is a natural low pressure zone [on the trailing edge of the wind, interestingly, can even be 'in front of' the wall, so long as the fence [assuming the fence is fairly 'wallish' so that the wind does not just flow right through it] has a decent drop in pressure, so that it is taking away the pressure.
it's a good idea but you are adding complication before the investigation is finished - we don't know how much power this thing generates and if it is sufficient why add complication? Sure you will get more power but do you need it? My goals are simplicity, cost effectiveness and sufficient performance - what you are suggesting conflicts with those goals at the moment - I am not saying it will always conflict but I resist adding complexity as a general rule - hope this helps
I've wanted to do that for years! Find you a big HVAC squirrel cage fan about 1m in diameter, and you'll generate some torque, especially with a concentrating cone in front! Keep up the great work!
Here's one for you to try if you'd like. Simply use a ramped shroud over the return blades so the wind isn't working against them. This is from a side wind not your flat design (which is an un-shrouded jet turbine engine blade set up by the way). This will both ramp your blowing wind into the "catching" part of the cage blades but also blocks the blowing wind resistance (not all air resistance of course) from the returning side blades. Great use of lock down time making all these videos. Keep at it.
Always great experiments. And your absolutely right. these guys that say stuff negative stuff about these experiments doesn't understand the invented minds. Nor do they understand the potential possibilities. Thank you for all your projects you share with everyone. It does help out the ones interested in new idea and progress. And one day we will find a cheap and easy way to power stuff by doing what we are doing experimenting.
This video was helpful. I have been considering building a silo type structure that would be covered by opening that have simple one way doors (think doggy door) that would blow open and allow the air to push in when the wind hits them on the windward side and are held closed on the downwind side by the air that is blowing into the structure. Once inside the moving air flow would be directed down and funneled through a fan at the bottom of the structure that would be used to drive either a generator or drive a heat pump directly. I look forward to seeing what happens with a bigger fan .
Yes, I really like this idea. I built a wind turbine many years ago. I used the gutter pipe idea for the blades and it worked well but the problem was I lived in a second-floor flat at that time so making any use of the turbine was "impossible". Now I have a large back garden but the windmill generator would still cause a hazard unless it was mounted on a very high pole but this mouse cage type generator would be absolutely perfect in almost any situation. It could be put on the side of your hut and used as a trickle charger with a diode for a car battery if you had no power in your hut. Now you got me using the old grey matter Robert. 👍 I meant to add: What, in your opinion, would be the best-fixed magnet motor for a small generator like this if a car blower motor was not available? Cheers mate. 👍
Some RV campers have a 12 volt dc ceiling fan wired in them. I don't think it would take a lot of wind to make a lot of power with one of them. Especially if you set up like this.
I was going to say jokingly, you should put it in my back gate as the wind whistles through there. I then realised that's what they did with the hoover dam and that works fine, you'll explain why far better than me Bob.
@@ThinkingandTinkering lol, perhaps it's just my gate. It faces Sw and is between the garage and the house{dam} effectively making a giant funnel for the air to go through. Even on light wind days I can barely shut the gate. The hole might be a bit of a downer for security but putting your hand through spinning blades may make the local burglar think twice. Just checked and joking aside the wind through a metre wide gate opening is over twice that of the front or back garden, as the gate closes the restriction accelerates the wind even more. The way your shutter were Wratting last week you may have the same aspect.
I've just had an idea about your Stick Wind generator. Many lamp posts have solar cells on top of them to power them, you could also turn the lamp post into one big stick generator,, or put a few onto the post to add their out puts together.
Hi Rob, Intrresting, air flow optimisation on a diy house project could be found by studying the air flow around, past or over a building. Usually there's a couple of prevailing wind directions and one would generally find it speed's up near or at corners, eaves or ridges, as you ssy keep just below for planning. Take care to use safe access equipment for working at any heights.
Hi Rob, I was told by someone that an Idea for all in one Sound system would not work, it, turned out to amazing so you have to do what you think is right and experiment otherwise we would still be in the dark ages
The cone was surprising how much it improved. Not sure how you could try it with scraps but it seems a Venturi after the cone would increase air velocity with no moving parts.
I've not read all the comments and I'm sure you've thought of this before but what about those spinning s-shape shop signs that were all the rage a few years ago? They seem to turn easily in light wind, have a large surface area and no doubt with greater knowledge be modified to be more efficient. Either way that template should be easy to make and balance out of even scrap sheet steel or aluminium. Ok, not house wall stuff but certainly shed roof?
Watching this in Apr 2022 of course you made a huge one using magnets and coils.amazing how the time line runs-not knowing at the time of this video if you were going to persue this project.great job anyway
I live in a top floor flat, I am trying to create a generator that takes advantage of that, there is a natural venturi effect, however it's a council property, so I need to go careful how I implement it. I so wish I had private property to test my ideas on, as it has been my obsession for over 20 years.
wow thats concentrated wind energy and it reduces the amount of lightweight composites materials and motor size. the good thing about vertical axis is that if wind direction changes they adapt instantly. vertical axis work better in arrays and are probably the most efficient because when you think about wind power sails are most used structures, so if you make a vawt with 3 slim sails that rotate making the same angles a boat makes against the wind it must be quite efficient. however it still makes noise and disturb birds. this system of concentrated vortex wind generation looks like is more efficient in materials and has less noise and dont disturb birds which it must be the real concern here.
A squirrel cage from a forced air furnace for a house may be sufficient to drive your Nissan blower motor. It may be a bit heavy, but sorting that kind of stuff out is much of the fun!
Hi your posts very interesting, especially wind generation using Nissan heater fan wheel. Would like to point out you were blowing air into the intake side of the wheel which is normally powered by the motor. If you were to turn the wheel 90 degrees and blow the air at the blades like a water wheel it would have more effect. Also if you were to use your cone effect and flatten and angle the air stream it would optimise the power of the air. It then should charge more than a phone. Also condensor/cooling fans off a vehicle have the same effect in reverse, optimising air entry to improve output in terms of energy. Most motors are generators in reverse mode
I think it’s quite worthwhile because things like this are a path to more learning for example the cone effect seems quite stark I could only guess at the gain in pressure/ efficiency that it introduced but it looked large just on observation. Regards
Thanks again Rob You always come up with a practical application for everyday things If it is possible to attach this motor to a small air compressor for inflating things please post a vid on how to do it My girlfriend is feeling a bit down at the moment Make my day
He actually did a project 3 days ago that would give you some idea of how you might make a DIY air compressor. The title was "Turning A CD DVD Drive Into An Air Engine Generator". In the video, he used air to drive a piston in a cylinder in order to drive a motor and generate electricity. If you reverse the design, and use the motor to drive the piston, you could create an air compressor. But I don't think the CD-DVD motor would be a good choice without gearing, and even then it would be really slow. In addition, you'll need a valve set up to close the output and open air intake when the piston is retracting, but that opens the output line and closes the intake when it's pumping. But it definitely gives you an idea of how to set up a motor and piston to pump air. The CD-DVD motor might be powerful enough to pump air into an aquarium given you wouldn't need much volume or pressure, but I think you'd need considerably more torque to inflate things. This blower motor would likely be powerful enough.
increase the cone length up to flush with the edge of the squirrel cage. the intake cone should probably have a bit more length and a taper. put this in a windy breezeway or any place really that gets consistent wind and you will have power. as for the squirrel cage itself id also modify it so the vanes are about 1 1/2 times bigger. more surface area and more inertial mass. add neccesary diodes on the back end to a decent capacitor to help with load fluctuation and your golden.....i think.
You will notice when you measure the wind speed of the fan and compare it to the wind speed of the funnel exit that there is a tremendous difference in speed and that it is not only that it collects and focus the volume of air. So if one decides to make an multiple array arrangement against a wall,I can vision a cover that covers al these fans with the holes in it,estatically I am sure it could appear pleasantly on the eye's so this will have severall purposes 1. Boost the Air pressure 2. Boost the speed 3. Collect and direct the wind. energy on the turbine blades. 4. Serves as a beatifull designed cover for al the hardware.
Thanks Robert for your Car Blower Generator video, I enjoy all of your videos. I would like to ask your opinion, if several of these these generators were mounted to a wall would the wind pressure passing through the generators interfere from one generator to another? I suspect the wind air pressure exiting these blowers may combine to create some odd turbulances and pressures reducing the total output of the system.
I suspect the cone is doing more than just collecting more air. It only has about twice the area of the rotor intake, yet without it the rotor didn't turn at all. I think what's happening is that without the cone, as much air is blowing around the rotor as through it, so there's hardly any pressure difference to create a flow from inside the rotor to outside. But with the cone in place, air is shielded from blowing around the outside. This idea could be tested by trying just a flat baffle with a hole in it instead of a cone. If I'm right, this should also spin the rotor, although maybe not as strongly as the funnel.
Ok it might not be efficient on just any wall per say but what about a wall in a city highrise that has tight isleways, kind of like the ones that are only big enough for foot traffic. I bet they have tons of wind pulling through those isleways. Also under bridges, there is a lot of air flow. Use this and use the other wind\vibrate method that you just built with the twisted ribbon and wah-la, you would have enough power to run the led lights on the bridge or streets. Fantastic mate
Wow! You ran with it! lol .. This has gotten me to thinking even more about something .. bc I'm in the process of getting my roof replaced .. from shingles to metal .. and on my house there are 3 good sized vent turbines. I was up there recently with my neighbor and looking at things. He went over and held his hand next to the turbine that was moving at a pretty good clip on a sunny 90 deg. day. I felt it too .. a stream of heat was swirling out of that turbine. So this video today has got me wondering what it would be like to have a large black box through which heat could collect and pass. My roof area is about 34 x 90 ft. makes me wonder what would happen if all that heat was funneled through one passage. Just not sure there would be much natural force behind it .. but it's interesting to think about. Many very old houses have high ceilings .. about 10 ft or so .. that is so the heat would rise to the top .. a natural way to cool a house. A cupola or heat chimney would also sometimes be used to take the heat out. "Cupolas were originally designed to add natural light and ventilation to the area under a roof. They sit on the ridge of a roof and can be found in many shapes, including square, round, and octagonal. On barns, they're meant to allow a continuous flow of air into the hayloft, helping to dry the hay."
........That's good fun .The improvement with the cone / funnel isn't probably for the reason we might think but I'm too tired to think it through .. That radiator appears to be copper based and it's a dying breed and getting hard to find .I'm pretty sure that digital scales can be used in vertical configuration to measure wind flow pressures , so folks can do measurement of pressure variation from wall in incremental approaches to the fan. Then measurements can be made at points behind the cone and in front etc. . . .
As the squirrel cage works differently from a rotating blade in the air flow I.E it is driven from a high pressure inside the cage flowing out through the side blades to equalize with the ambient pressure there is a possible way to increase the output by mounting the funnel on a curved wall in front of the squirrel cage this should lower the ambient pressure behind the wall and increase the pressure différance that it is trying to equalize.
It would be interesting to see a turbine build that could charge a decent 12v battery or 6v like a motorbike sized one in reasonable time and then run some useful item(s) on it via a 220v convertor
Those vertical oscillating fans are usually available for pretty cheap at thrift stores and garage sales ... even free on Craigslist and Facebook (They don't pack well, so often get tossed in a move) You may need to rewire the motor, but the squirrel cage is much bigger than a car's blower fan yet lighter and already has the right bearings. Honestly you can probably use just a single motor and connect several units in parallel using belts or chains.
I would like to see more investigation on improving the exit air flow. Putting a conical cowling over the squirrel cage that directs the incident air flow away from the might have a double benefit. First, with the generator mounted on a flat surface, the incident air will create a high pressure area around the squirrel cage that will hinder the exiting air flow. Putting a conical cowling around the squirrel cage will direct the incident air away from the exit path and, if the gap between the wall and the bottom of the cowling is set right, the venturi effect will make incident air flow create a negative exit pressure as it moves away from the generator. Something like the Dyson "bladeless" fan.
@@ThinkingandTinkering - I was hoping you would save me scrapping a car of my own and then there is your comments on efforts of removing the blower, but thank for all the good work and neat ideas.
ON IT Robert . i do find it amusing to hear comments from your viewers 'it has constantly bewildered me why we are not using more micro systems ... perhaps there is a comparison to be shown between macro and micro energy producing power ? there is another factor to consider ... the wild life that get destroyed, large turbines large motors chewing up insects and birds .i see an advantage in small less intrusive systems ...but why is there such little interest ? is it human nature to go big ???? are we big power beings i draw comparisons from nature producing all its power locally and on micro scale ???? Efficiency????
Always enjoy watching your video,s Robert, it,s always best to approach these type of projects with an open mind but unfortunately for some people..."If you have to explain they will never understand" regards Doc Cox.
I think you'd be better off putting the squirrel cage from the tower fan horizontally just above the gutter or just below the apex on an apex roof thereby avoiding planning regs and benefitting from air accelerating as it's coming over the roof, the question is what position would give you the best result?
Fantastic work keep it up love to see a vertical wind turbine that has long vertical side funnel to force more wind onto the drive side of the generator blades and a shield on the other side to stop wind slowing down the generator and the shield and funnel can turn into the wind like a wind vane for direction like on top of a building that shows north east south west to always keep it into the wind just a thought :)
Another suggestion might be to "sandwich" the rotor. So you might have a second skin with a hole the size of the inner diameter of the rotor (rather like your funnel) just over the top of the fan. This would then ensure that the escaping air is not being interfered with as much by the wind from the fan. You could play with variations in size of this, including even preventing this from allowing air in from the sides, while allowing air out freely. Just a thought.
I’m trying to think of scrap items you could use as a cone... are there any local companies that do industrial ducting? I bet they’ll have something like a reducer from small to large ducting that might work. Also would a washing machine/dryer drum work if you cut ‘slits’ down it and twist each of the remaining ‘strips’ to form the blades of the squirrel-cage?...
Very nice pancake motor. Can't wait for that one. Though maybe not appropriate for this type wind generator I have noticed that rooftop attic turbines seem quite efficient. I have seen them spin quite fast on dead calm days.....just from the heat rising from the attic. Not sure how you would attach one though.
Spookily I had recently emailed Robert with the very same idea, as, like him, I am irked by the idea of having to apply for planning permission to put up a turbine. And I'm pretty sure I won't get it anyway. So I thought an attic vent, maybe with up specced bearings, could become a 'stealth' VAWT! And, following Robert's video about improving the efficiency of solar cells using CDs, am also looking at heating an immersion heater coil from a PV cell via a charge controller. Robert sows the seeds and we can try and make them grow.
I think the squirrel wheel has a down side, which is, the part that don't expel the air that hits the wheel from the outside will pull air from the middle and try to push it out. Maybe a D shaped gard would help. Yeah I will do my own experiments eventually. Lol
lol - you are right mate - there are bound to be issues with any design it's really about how you tackle those issues, if the issues are significant and if the resolution costs more than is worth it for the output
vertical turbines are simple and bullet proof (mostly). these small ones would useful for remote low power sensors for example. of course a solar panel would work as well but they're not as fun to look at.
I find your Outside the Box recycling concepts, pure Genius !! We all need to adopt a new mind set of "Product Live time Energy Balance". We as consumers to often get caught up in the end result and not the Big picture. We will spend ten thousand watts of energy during production to produce a solar cell that might be 2 percent more efficient. Not to mention all the harmful environmental effects such production might cause. Yet that solar cell may only have a projected life span of only 5 years and a total energy production less than the energy it originally toke to make it ! There can be Know higher net energy gain device, than a unit made from recycled products ! LOL just the energy saved from melting the product down to recycle it under conventional recycling concepts will most likely be more than a New product will even produce.. You have caused me to reevaluate and see energy in a whole new Light !! For instance I now use the waste heat from my A/C to dry my cloths, and the waste Gallon of distilled water an hour.
Sorry the last part of that got cut off. I run the A/C water run off through a Sawyer water filter and capture almost a Gallon of distilled water an hour!! LOL thanks to you I Now see waste like Batteries! Objects that had energy put into them during there creation. The new challenge is to extract that energy back out through recycling....
I would find it really useful to see an exploration of how to collect the power you can generate from small devices like this, without having to go nuts on huge batteries or electronics that seem beyond me at the moment.
If you want to put a wind generator above the roof line, then you could integrate it into a TV antenna. You can have up to two TV antennas without planning permission.
this one shows a fundamental difference between your attitude & that of the nitpickers; you are fundamentally curious & Optimistic, as are many commenters here. the nitpickies & naysayers tend to be fundamentally pessimists and look at everything as glass half empty.
it's because we have hope and care for the future mate - the negatives only care for themselves - it's why they want something now and for them and if it doesn't do that they complain
Lucky for me I had the smarts to move out of town 30 years ago. They can STUFF they're permissions and granted OK's ! The Code here is what do I feel safe with and doing ? LOL
Great show thanks Robert, just sold my Nissan for scrap, I wish that I'd seen this back then. Why would you need permission to stick a wind generator to your house? You don't need permission for a TV antennae or satellite dish. We should be encouraged and rewarded for saving power not penalised. Interesting stuff with the cone. I once saw a film where a big ring encircled a wind turbine which then tripled the output. Why does this happen and if it works why aren't all the turbines so equipped I wonder?
I have no idea mate - the satellite dish is no probs because it's below the roofline - even so you can't stick it on the front of the house in some areas - like the lakes for example - that ring is often referred to as a shroud I believe
I like your videos i just wish you would show us your meter reading volts amps and current produced from the experiments either good or bad i like to see the numbers for myself
I used to take the squirrel cage fans out of air conditioners in the US that is and stack them up to make a larger area Four Winds to catch but never used it never got around to putting it on a motor
Am doing a design with offset of blade arrays in 4 Stages causing a cascading spiral, that should eventually help to catch sufficient air and get it moving.
I would have liked to see you move the fan to hit the squirrel cage on an angle because I think you would have seen the motor turn. The cone is good for a head on wind but when the wind hits at an angle or from the side it will turn the motor.
@@ThinkingandTinkering I would have thought it would bounce off the wall back into the cage because as the wind hits the side of your house it is channelled along the wall to the back
@@stevetobias4890 yeah maybe mate - I don't really know I am just guessing and giving it a go - but wait until you see tomorrow's vid - tbh it's awesome lol
Having the cone in front would also deflect air down to the wall making it denser on one side for a side windand effectively a low-pressure area on the far side IMO.
I wonder about the plain old kids pinwheel design- those seem to spin with very little air, far less than any normal fan or prop blade design of the same diameter. or take your squirrel cage, you could just Blow on a pinwheel of that same size and I Think get more bang for your buck out of it than you could blowing into the cage. I could be wrong of course, but I think that might work in the compact wall mounted sort of device you're going for. additionally- you know those round whirlybirds on top of houses and barns and such for roof ventillation? That sort of thing might Also be a good option.
I did a pin wheel thing here mate ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KqfCJoHtsak.html I have collected the vids into a playlist now as there seems to be a few lol
Good day Robert. How many watts can the squirrel turbine with the wind cone in this video produce.? Can it power a 50W lightbulb? It seems the setup is much more efficient than the typical vertical wind turbine wherein the latter's returning blades are a drag to the incoming wind.
If your intention in building small wind turbines is to create usable power, it is time for a reality check. I have built these things for over 50 years and my tiny savonius rotors power a magnet-loaded rotor through a pick-up coil and produce about 14.2 volts at right around an amp. Not much, right? That's why I have several of them in series. Look at the commercial units out in the countryside. if you want to create real usable power, you are pretty much going to have to do what they do and increase the size of your machines by like a million times bigger. Sorry, that's just the way it works. I Believe In The honeybee theory, namely is that 10,000 tiny honey bees can do the same work of one giant 400-pound honey bee, if you catch my drift, which is why I have multiple smaller units tied together electrically to create usable power.
What happens if you move the fan to the left or right of the squirrel cage and angle the cone into the direction of the on coming airstream? Does the cage still turn as it did? If it does, could you rig the cone to follow changes in direction of the wind like a weather vane to always direct the wind to the cage? Then it won't matter in what direction the wind comes from. Just wondering if you have tried this? Now I can't throw anything away. Everything has a use. 👍
I wonder if you place a cone inside your squirrel cage the more efficiently guide the incoming air. Illuminating it’s smashing into the flat wall created by the hub.
Healthy criticism is needful sometimes, but I have no respect whatsoever for nay sayers. I uphold dearly, with great honor and careful reverence, the creative initiative within the heart of the dreamer; may your gifts make room for you! Place the assembly on a weather vane, shape the shroud and the blades for maximum advantage and efficiency. Reverse the process, use a heliacal bladed fan, or somethjng like a corvair cooling fan as your mass (air) redirecter/mover. That will generate a huge wind storm.
absolutely agree mate - to be honest I know there are issues with this idea but just to say - oh no - that won't work isn't criticism.i like your vain idea - cheers
It is worth looking at, as you say! How's about a step up to a fully working off grid 12v charger ? With inverter in mind, I'm a southern boy and can't use millivolt,s or miniture amounts Ladd
Sorry to disagree sir, I mean why the fan turns. I believe the fan turns with the funnel because funneling air into the center of the fan while shielding the outside of the blades. This creates a pressure differential, or a place for air in the center higher pressure to escape to a lower pressure area shielded by the larger diameter part of the funnel. When you move the fan closer, this same effect is created by the "mechanics" of how this fan blade moves air, only to a lesser degree. But that's an interesting effect and lends to "how" to engineer that effect into a working wind turban.
robert i agree that these small generators are interesting but unless you can concentrate their output it is had to do anything with it remember the average car alternator is only putting out about 500 watts so whether you use air, hydraulics or electric you need to store some of this to concentrate it so you can use an alternator or motor to put useful amounts of power out when you start trying to power things off these small power sources you begin to realize just how cheap power has been. i am not saying to, not do this what i am saying is needing to use less is a big part of making micro power useful so the first step will always be how can i do it with less .
Can you glue 2 plastic funnel necks together to produce the Bernoulli effect of increased wind velocity to spin the flat generator faster for increased output?
