And I think this is what all the world needs right now: "Make energy harvesting as easy as gardening" . Also train people so that there will be as many energy harvesters as gardeners, if not more.

[@ThinkingandTinkering]

100% agree with that mate

[@biostormyliner9489]

Autonomy at first of course....

[@Buzzhumma]

Actually you can harvest energy from the growth of garden in a variety of ways with highest effecient way reported as methane from decompersition. More than twice as much btu than when biomass is dryed and burnt which I think is amazing rather than all that methane contributing to green House emissions which is said to be over 30 % just from cows breathing. Most people think its from the nasty end!

[@theideasman6018]

Do the blades need to be curved. Or is flat ok

[@worldrider9087]

@@theideasman6018 It depends on the size. For smaller devices flat or curved would be almost the same with negligible difference. But if you go big then it's a good idea to get help from aviation people who spend a lifetime trying to find the best wing shape for airplanes.

Thank you!!! Absolutely pump out incredible content. I realized after messing around looking at old videos, that I watched some of your very first videos when they were still new. I was trying to make my own ink for electroplating. Here you are almost a decade later responsible for inspiring me into working myself into quite the amazing position. I appreciate you more than you could know.

Outstanding! Beautiful design and construction. Also hyper-interesting as all your stuff is. I especially love the use of the rain gutter instead of similar pipe. I was thinking of doing the same thing with 29-inch / .74 meters bicycle wheel. That's the largest "Standard" size wheel or I would have gone bigger, but I am not much of a handyman, so the idea of integrated bearings is attractive for me. All good wishes! I'm going to see the other parts right now!

[@dremaboy777]

Beautiful. Absolutely beautiful. To see these ideas coming together into this creation. Fascinating. I'm almost certain this design, concept, and idea you've put together as a wind turbine, will be one I'll be using as my new favorite "very efficient wind turbines design". I think this is amazing. And will be QUITE effective and efficient. The only other thing I'm hoping, is that you use that magnet arrangement that greatly reduced the cogging, while dramatically increasing the flux frequency. I truly think this is amazing Rob.

[@ThinkingandTinkering]

thank you mate and thank you for posting - tbh I am not sure at the moment what magnet arrangement I am going to use - but I will be thinking about that soon

Very nice Robert and impressive. Big improvement in your sound quality too, Love it! Also want to thank you for your book on conductive inks that I got a while back and many videos on the same subject. I finally put your info into practice and made some conductive ink for shielding purposes inside electric guitars using mathylated spirit as carrier and shellac as a binder with graphite powder. Still working on the proportions, got decent results so far. Next, have to build myself the square probe. Thank you very much good Sir. Oh and I love your attitude towards things, great curiosity and excellent understanding of some fundamental electronic principle. I wish my understanding of chemistry was half as good as yours.

You know, I'd been wondering about what use one could possibly find for the base of a swivel chair ... You see these chairs dumped all the time and it's a shame as the base (and usually the lifting mechanism too) is always perfectly functional (with the exception of a few castor wheels missing). Using it like this is a brilliant idea and will possibly open the way to generating multiple others for their re-use.

[@Alienami]

I liked the idea, but his plan relies on two almost identical ones, or you get wobble. If you made a more traditional horizontal fan style, you would only need one, and that would be fine. I would suggest using bicycle wheels, as they more are universally found, for this drum style. And for the blades use duct tape (or sheets of linen cut to size) coated in a Resin, moulded over a pipe (protected by cling wrap)... That way you have a reliable and cheaper source of blades.

[@johang1293]

Excellent, looking forward to see it finished. Hopefully you can put magnets and coils on both sides of the drum.

[@ThinkingandTinkering]

I won't mate - there is a point of diminishing return and tbh my earlier experiments suggest they aren't needed

[@handyhippie6548]

the large wheels from an old wheelchair would be a good source for something to attach your blades to that have fairly good sealed ball bearings in the hubs. and since most have plastic rims, you should be able to glue the plastic blades directly to the rims. plus the remainder of the chair has many other parts that are useful like the large caster wheels, the vinyl or cloth seat and back, and tube frame. i got over thirty of them for free from a nursing home that was disposing of chairs that previously belonged to deceased patients that i have made many things from. one of them are folding camp/work stools i made for myself and my friends from the part of the frame the seat is attached to on folding wheelchairs. it has an x joint where it folds together already. i cut feet from the vertical tubing that the back is fastened to with a cut off disk on an angle grinder, and attach them to the u shaped bottom pivots(a source of thin sheet brass for shim stock) with hardware that i removed from the chair. presto! a free and really strong folding stool.

Why would it need a thrust bearing? There is only it's weight bearing down, and that isn't much and would be well withing the rating of a standard ball race I'd have thought. Bearings are often tightened to a slight pre-load anyway.

Dumb question time - IF you could block off the side of the blades that offer counter-force to the blades, would the rotor turn more efficiently? I was thinking of curved shield that rotated with the wind, like a wind vane, that would cover half the blades.

How to accurately determine the correct blade angle and blade width in relation to the rotor radius?

[@ThisRandomUsername]

That does look very solid. If there was any consistent kind of wind here in Durban I'd probably be building myself one of those eventually. If your drum is out of square slightly (Which you say it isn't, at 1mm), you might consider putting the magnets in a perpendicular arrangement around the circumference and have your transformer core vertically at the bottom. That way you could use your pen trick to get an exact mounting ring, and it'd probably be more resistant to flexing if that's a problem. One difficulty with that is you'd need to be exact in your mounting instead of relying on the thickness of the magnets. Either way, I really like where this is going.

[@paulmaydaynight9925]

im surprised that you dont get a lot of wind being the "blackpool' of South Africa ^_~

[@ThisRandomUsername]

​ @drop stix Great idea. Are you talking about making the face flat, or the circumference round? As J W is concerned, I'd worry about flex pulling the circumference inward as the blades bow outwards at speed, increasing the gap to the magnets if they were mounted onto the flat face. If they were mounted around the outside you'd get more consistent, but you'd probably have to modify the transformer core to be concave to take the magnets as close as possible. ​@@paulmaydaynight9925 Yeah, we hardly get any extreme weather (apart from a bit of heat sometimes). I think it's because we have a pretty consistently hot ocean temperature flowing from up north. Further south there's a lot more wind, where there are two ocean currents nearby of rather different temperatures.

Hello Robert, thank you for so many hugely interesting videos! Can you tell me what happened to all the episodes about the wind turbine (I forget the name, I watched them once or twice last year but now they appear to have been removed from your site, so I will try to describe it) which began as two plywood discs, about 1.5-2m in diameter, sandwiched together with 3 curved air guides in between? There is a hole in the centre for air intake (increased the swept area to beyond the area of the disc) and the air passing through the system exits at the perimeter. You got lots of feedback around improvements which you then applied, eventually doing away with the front disc altogether and shaping the 3 'blades' into the mathematically ideal shape. Are these episodes still available and, if so, where can I find them?

hi, when it comes to wind turbines the design turns around the speed of wind available and so the rpm you want to work with, there're charts with different rpms and voltages for the same washing machine motor by changing the wiring of the coils. I think your work as experimental is pretty much needed but to help you carry the weight a feedback from the public to build things or working with other youtubers could do the trick. This wind turbine looks pretty good, the choice of materials is pretty good and I want to see the results, you also could try making molds with 3d printers to pour melted recycled plastics, and so you can make any object of any shape you want for the cheap, you can use an easy design software as sketchup. greetings, ayoze
