Since the windmill will be pretty powerful, you can stack more than one disk along the shaft. Then you can coil your copper tube to pass between two disks with every loop.

[@sebbes333]

*@Way Out West - Workshop Stuff* 8:08 *USE A WEDGE to handle these types of magnets.* Make a wooden wedge, at a shallow angle, then wedge the magnets apart *but ALSO together* so they don't slam into each other & break (as you have done twice already). It is also MUCH safer for your fingers & other limbs, also be careful of magnet-fragments flying at high speeds towards your eyes. *You can also build a kind of wooden "scissor", to "sheer off" one magnet from the rest.*

[@1234567890CAB]

As it's setup right now, the magnets produce a magnetic field on both sides of the disk. That means you could put metal on both sides of the disk. Or you could use something called a Halbach array, which is a special way to arrange the magnets so that most of the magnetic field is on only one side of the disk.

[@Knotmuch42]

He would have to adjust the disk design a bit. Since he put the magnets inset in the surface, he would either have to inset magnets on the other side of the disk or make the disk thinner and drill the holes all the way through so that that magnet is flush with both sides of the disk.

[@phantomcorsair8476]

Smaller rectangle shaped magnets in the same space will give more pules per revolution, and if you place a coil of wire next to these magnets, ac current will be generated, which can be retified into dc for charging batteries etc. so this can be dual purpose, heating water and generating electricity.

[@adonisengineering5508]

Using a windmill to generate electricity... why does that sound familiar? :)

[@karyjas1]

Now just got to learn about halback pattern, minimize the distance between magnets and the metal, increase the interaction amount, aka more copper pipes, and maybe not pipes, but solid blocks with channels for water, maybe use pure iron to redirect the magnetic field so less of it is dispersed in air. Sounds like a fun project and i want to see success and good performance

[@ThalassTKynn]

And have the water pipe between two discs with the same magnet orientation, too.

[@karyjas1]

@@ThalassTKynn Another good way to do it it have a ring, with magnets on its inside, centrifugal force will be applied outwards, but the magnets are facing in, so they are kept in there tight, and then the metal piece that heats up could be in the middle of the ring. A minimalistic design

[@ThalassTKynn]

@@karyjas1 Yeah that'd be a good way to do it

[@onkelnb]

Do you plan on bending an omega-shaped copper pipe as a heat exchanger to cover more of the magnet surface?

[@KarolOfGutovo]

At this scale I think it'd be easier for one end to go in straight, and then the other turn sharply up and then meander into going back to the house EDIT: also, copper doesn't work well with induction, since it's a good conductor. You want electrical resistance for the heat to be emited. A PVC pipe with a carbon steel cable through the middle might be the best? Since it won't be heated on the surface. Or a steel pipe encased in some insulation

[@owllymannstein7113]

I was thinking that too, you could pump the water through the pipe and potentially regulate the speed of the water so that it doesn't get too hot before it leaves the part over the magnet. You could also potentially have two, one on the topside of the wheel and one on the bottom, depending on what (if any?) drag they put on the wheel.

[@KarolOfGutovo]

@@owllymannstein7113 making it go through the magnet heated part faster wouldn't change the temperature equilibrium though, as each liter would also emit less heat when going through radiators and would return to the heater warmer than if it went slower. I think a better solution for temperature regulation would be moving the pipe closer or further from the magnet wheel

[@redsquirrelftw]

Crossed my mind to try this with hard drive magnets, cool to see that it actually works. If you can bend a long copper pipe to go all around it so that all magnets are affecting copper at all times, I think it would actually be very effective. Could also have a pipe on both sides of the disc as the magnetism will work both ways.

[@londonnight937]

Tim, once you get the windmill and the magnet wheel setup done, consider the following: At zero speed, you have maximum torque on the windmill blades/on the magnets, but you produce zero power. At maximum speed, you will have zero torque being applied to the windmill blades, and zero torque at the magnet wheel. The magnet wheel is happier the faster you spin it, that is not of concern. It is the windmill blades who have this intrinsic bell shaped curve of their power output versus speed. At the ends of the graph, the power is zero. The maximum power point is somewhere in between, at a certain speed. That maximum power point speed varies a little bit with load and wind speed, and it is certainly not in the middle of the graph. Your best bet would be to have the windmill turn at the speed at which in most use cases the windmill will produce maximum power, or at least close to maximum power. What I want to say with all of this is, make sure that you don't try to operate the windmill at speeds that are far from this perfect sweet spot. If you can't adjust the blade pitch based on load and wind speed (overspeed furling of the blades does not count) then the only way you can affect this operating spot is by setting the reduction ratio correctly (between windmill and magnet wheel). The sweet spot can only be found experimentally. For this, the best thing would be a CVT (continuous variable transmission) in between your windmill and the magnet wheel, and measuring the power output while changing the CVT setting to see where is the maximum power produced, for your average wind speed. But for this experiment, you need constant wind. After you have found the ideal transmission ratio, a classic fixed ratio transmission can be installed, which is more efficient and cheaper than a CVT. Changing any parameter of the system (diameters, nr of magnets, etc.) will require you to do the experiment again. See this just like you see an internal combustion engine: the engine of a car is efficient only at a certain speed. Good luck!

[@OstrichWrestler]

Perhaps you can regulate it with the load using a centrifugal governor; controlling the proximity or exposure of the stationary conductor to extract more or less energy to keep it in the sweet spot.

[@londonnight937]

[@randywl8925]

[@GWAForUTBE]

If the copper was a big round plate with radial cooling fins, you would not need water. It would circulate air and heat it. Apparently aluminum works well with a carbon coating .

[@LabRatJason]

@@OstrichWrestler Came here to say this. Glad to see others thinking the same way. The simplest mechanism maybe a ramp shape where the coil is pulled up the ramp by the magnetic "drag" forces. As the coil rises up the ramp It gets further from the magnets and produces less drag. The incline of the ramp plus a return spring should be enough to tune and control the power output.

[@JamesSeedorf]

You could look at building a hallbach array as it concentrates a magnetic field on a single side allowing for use of less powerful potentially cheaper magnets, or just fewer

[@wayoutwest-workshopstuff6299]

So interesting, isn't it?

[@JamesSeedorf]

Yep! You could also consider spinning the metal thru some stationary magnets and dripping water onto the metal. Then you could put a magnet above and below to get a very strong field. I have a stationary bike like this and it can get quite warm.

[@tomtruesdale6901]

Very impressive Tim, I think you might want to consider some other material for the disk if you increase the speed anymore. I don't think I would trust MDF to last at higher RPMs. Also maybe build a bracket to hold the water pipe above the disk and make it bigger to cover more area, I bet it would heat the water faster. Hope your health improves very soon.

[@redsable6119]

You seen in the one clip he showed someone using an aluminum disk for the base. This is smart as it it tougher and will act as a heat sink to keep the magnets cooler, as neodymium magnets will lose their strength at higher temps.

I'm guessing that the MDF is a comparatively cheap test rig to see what sort of heating you can get from the moving magnets. Why sink the money into a fat piece of aluminium before you know it's going to work in your particular set up?

Hi! Here's another idea. Maybe you'll like it too. In some nuclear power plants, when they have excess rotational energy they want to dump, they have big spinning wheels partially submerged in a water tank. The wheels have cups that close around a volume of air when rotating -- and subsequently pull the cups apart when the wheels take them under water. It doesn't boil the water but it heats it up a lot.

[@MistahBufo]

This is fascinating as heck. I'm imagining the windmill powering a chain of gears that graduate upwards and in turn spin many magnetic discs, heating a large, even area of pipes on a wall or a floor or even suspended in the air above or below the spinning discs of magnets. Free hot water for as long as the windmill spins.

[@gabrielhacecosas]

I have been thinking and it seems to me that the best solution is to put a three-phase alternator with a small pulley, and another huge pulley like the one you already made and generate electricity, transport it by cables and put electric resistors inside the house. In the end if you produce heat and you have to transport it through pipes, it's expensive, cumbersome and you lose a lot along the way. And in Spain I have found old 20kw generators for 300€. I don't think your windmill will generate that much.

[@MrChainsawAardvark]

A few thoughts on scaling it up to the windmill. For one, you could have one large power take-off shaft, and then multiple belts coming off to multiple spinning magnetic wheels - much like how the old water powered factories of the early industrial revolution worked. Following on that, you can have more than one pully, and thus get a gear ratio/transmission effect going, so a large slow windmill can translate into small fast disks. Directly induction heating a house might be a bit hard, but boiling water with induction and setting up a steam plant might work well.

[@grimace4257]

Steam can be pretty scary at the best of times, careful Icarus 💡😂

[@WairarapaTV]

Actually you don’t need to gear. Just move the plate closer or further away and the inductive load will increase or decrease. If the wind is light keep the plate further away. If the wind gets faster bring it closer. This should maintain the velocity about the same.

@@wayoutwest-workshopstuff6299 Not sure how you mean with "reverse"? You can always spin the disk / base-plate in the opposite direction, that's no problem. But to "reverse" the magnetic field itself, you would need to physically change the magnets orientations. But from your wheel-construction, I assume you want the strongest magnetic fields to be aimed "upwards" away from the "base-plate", so i don't see any need for "reversing" the magnetic field, as that would aim most of the magnetism into the wooden plate instead, where most of the magnetism would be wasted. If by "reverse" you mean something about the "flips" in the magnetism? The shape of the magnetic field will be more "spiky" and it uses groups of 3 magnets to make 1 "spike". The magnet field goes "in" to magnet A, "through" magnet B and "out" from magnet C and back "into" magnet A (and half through E) again.

Cody's lab did something similar and managed to melt a small bit of metal with it. For heating water maybe get a thinner disc of aluminium to mount the magnets in and then have a coil of copper pipe on either side of the magnets for doubling the efficiency?, you could connect the two coils and then water will automatically rise up and form a very slow moving pump that can be used to automatically draw water from a container and heat it gradually.

[@MisterTalkingMachine]

The reason copper pots and pans aren't usually used with induction stovetops is that the electric resistance matters too, and with copper it's too low, try aluminum next time

[@Knotmuch42]

suggestions 1) curve the copper pipe so that it matches the arc of the disk. that way the ends of the pipe are getting the same induction effects as the middle of the pipe 2) make a stand to hold the pipe (something I am sure you thought of, but didn't bother with for this proof of concept) Ideas 1) A loop of copper pipe that matches the circle of magnets so all the magnets are utilized all the time 2) several curved pieces of copper pipe that when laid end to end would make a loop that matches the circle of magnets (the separate pieces would either need to air gapped or insulated so that the electrical inductance does not transfer from one pipe to the adjacent pipe) Then compare the results of the 2 set ups

Basically this is an electric generator with a short-circuited windings. It is possible to move the heating part to another place, but then you will end up with a regular generator and heater.

no, the copper should be one continuous plate, so as to let eddy current form around each magnet, as they do. they dont make a "current" flowing "along the pipe". they make a small "eddy" directly above a magnetic pole. pipes dont contain enough "conductor" to allow a free path for induced eddy currents... unless you happen to push the magnet THROUGH the pipe. at whic point eddy currents will be produces AROUND the diameter of the pipe itself. the old trick of dropping a magnet down a pipe...

Neat. The temperature thing is the big issue. One of those laser thermometers will help. A design where the magnets are locked between two sheets is a good start, whether you rotate the magnets or not. One magnet coming adrift with low clearances and high speed will likely rip all the other magnets out in an explosive disaster. Even one at 1000 rpm is undesirable, it could cascade the wheel out of balance. Glue doesn't like heat either. The two sheet thing requires fatter magnets to leave safe clearance. The magnet ring could benefit from cooling fins on one side, but this uses power, but you might be able to duct the warm air somewhere useful, away from the magnets. You could also go full boar and along with heating water on the bottom side use the finned side to generate electricity via other magnets. It all depends on the size of your windmill, you're just harvesting the 'free' power. Good luck, stay safe.

I think I have mentioned this in an earlier video, but you could use an electric motor with permanent magnets as a heating element. Simply submerge it in water and short the terminals. Basically, use the motor as a generator and convert the current directly into heat in its own windings. This would be far easier to build and the magnetic fields are much stronger, so no need for a transmission. Also the loading could be controlled if the leads are not shorted directly but with a resistor in between. Different resistor values result in different loads. Please give this a try and if you have questions, feel free to ask.

[@MusikCassette]

it also kind of is the same thing.

[@srmofoable]

Oil would be a far better liquid to submerge the motor in..... .... but really why submerge it? As you said, just short the winding with a heating element. But I don't think this is really about getting the job done efficiently. It's probably more about content and playing around.

[@bobsmith5088]

Not sure I understand that completely, but it sounds like it would only work at high rpm.

[@wideyxyz2271]

This is just a test of concept mock up. I'm sure more durable materials will be used in the final construction.

[@PermireFabrica]

@@MusikCassette Yes! That's the point. However, far easier to build and I think also cheaper. Plus, the benefit of controlling the load is also kind of neat.

[@dudu4027]

Nice. Thank you for the video 👍 I had a past project to replace my house boiler by a non mouving copper sphere with water flowing in the sphère. The sphère was surrounding by magnet attached to a windmil shaft. The windmil can follow the wind direction by turning arrond the sphère axis. Simple is beautiful.

@@wayoutwest-workshopstuff6299 I Never buid it. I leave in south of France and the sun is more powerfull compare to the wind. So i build a solar thermal system to heat the floor.

[@mckenziekeith7434]

One of the things you will eventually have to work out is how to adjust the mechanical loading of the windmill as windspeed changes. This is important to extract energy efficiently. The only way I can think of without dramatic changes to your system is to move the copper farther or closer to the spinning disk (rotor).

[@sebastian19745]

One idea for making it more efficient. Make two magnet disks and mount them with magnets facing each to the other. Between the magnets, put a loop of (flatten) copper pipe. And turn the disks. The polarity of the magnets on the oposite sides (on separate disks, facing the pipe) may be N_N or N_S, you may want to check to see what and how big the difference is. Also, the distance between the magnets and the pipe should be the smallest you can achieve. Also, you can make a small coil (maybe with a iron core) from few turns of copper wire and measure the voltage and frequency of the induced current when placed bettween the two magnet disks, and so you can also see the difference in the magnets polarity beween the two disks. The frequency being in the low range, you can hear it through a speaker or, better a piezo speaker. Cant wait for updates. Btw, Cody from Cody´s Lab, has done something similar few years ago.

[@MultiBigDenis]

Add a copper winding to the wheel with magnets and we get a generator, the energy developed on it will be easier to transport to the house and easier to regulate, and at least something will really heat up. My acquaintance has a two kilowatt wind generator at the peak (until they were light, at the initial stage of construction, the wind energy was used, and now this is a reserve source of energy) in winter hesitates the garage, while watering the garden in the summer ...

[@awatt]

No

[@carneeki]

I think an interesting experiment would be if you could run a loop of copper above the disc, and also below the disc to see if you can use more area to get faster or more efficient heating

[@MikePerreman]

Thats so cool, i bet you could get quite a bit more than 100°C if you let the pressure build up

[@TheZombieSaints]

Now you're talkin'! Can't wait for your future videos 👏👏👏

[@vsiegel]

The "Can it run Doom?" of magnet constructions: "Can we do it with Halbach arrays?"

[@YodaWhat]

There is no Halbach array in the video. What is there, is a VERY crude approximation that uses the magnets inefficiently. To make it much more efficient and much more like Halbach arrays, the magnets should be placed of a rotating steel disk, which will provide a magnetic return path for the magnetic fields, on the 'cold' side, the side away from the object being heated. The benefit is that on the 'hot' side, the magnetic fields will be more intense, and that will "jiggle the electrons" more violently, creating more heat. It is not perfect, but it is an improvement.

[@oldbatwit5102]

Wonderful stuff. I'd imagine that the main problem of wind power will be the gearing.

[@GHOOGLEMALE]

Very interesting - A great experiment - Can't wait to see your next test with it

[@CALOCALKY]

That so cool ,a water tank above and, ide soposed another below wouldn't duble the contact surface area

[@growleym504]

It would be interesting to see the change in torque on the shaft, when metal is heated within the oscillating magnetic field. Without a torsionmeter of some sort, one could maybe just measure the changing current drawn by the drill press motor and convert watts to horsepower and torque. There must be a back force from the eddy currents in the heated object. An example already in use and manufacture is magnetic braking on an aluminum fishing reel spool, which is quite effective in making casting without backlash much easier. So obviously that concept is worth exploring. Also, you should try placing a metal object in the field that is free to rotate coaxially with the magnet rotor disk, and see if you can cause a non-ferrous metallic object to function as a motor. This concept could be used perhaps as a not very efficient torque converter or constantly variable transmission.

[@scott98390]

This is fascinating - I've missed your content, Tim.

[@zestoslife]

Blows my mind that it works with non ferrous metals. If you hadn't shown it working with copper I wouldn't have believed it. Hope your health improves.

[@peters9929]

There are a number of utube videos where magnet is dropped down a up ended copper or aluminium tube. this is how a reluctor brake works as found on a engine dyno really magic stuff

[@baladar1353]

AC generators (alternators) work on the same principle, the difference is only they have coils of copper (eletromagnets) instead of neodymium magnets. The (primer) coils need to be excited with some current, this way the generated current can be regulated easily.

[@ShadowManceri]

It would even work with plastic bottle and water because water itself is slightly magnetic. But it's not efficient at all.

[@zestoslife]

@@baladar1353 I hadn't connected that copper wire isn't magnetic in the power generators / alternators. It is obvious know you mention it, funny how dots can stay unconnected for so long.

[@SunRabbit]

If you calculate the amount of wattage used to propel the drill press, and calculate the amount of heat generated, you'll find that it's less efficient than a toaster's resistance heating element. The most efficient system for generating heat is a deep-Earth geothermal bore where for a one-time investment of [a LOT of money] you get essentially free heat forever. Mostly used in places like Iceland where the Earth's crust is very thin, but you can do it anywhere.

[@katelights]

you should be able to maximise output by having the copper tube go all the way around the circle. then you could circulate water through the loop. I suspect the optimal solution would be a large disk of metal with channels through it for the water to flow.

[@oOfretlessOo]

I would add heat exchanger/accumulator to heat up a water reservoir that would then heat water passing through it. But consider pressure safety. Magnet disc in this setup won't be able to produce enough current for substantial flow heating.

[@HugeRademaker]

"I am still ill..." Meanwhile working his ass off. You are amazing!

[@martinpalmen3917]

If you make 2 circles with magnets on the disk and a spiral of coppertube feeding water from innercircle to outher circle you could make a closein inductionheather for the pool or to heat home in a closed system

[@stevergr9039]

You can increase your efficiency quite a bit by having two identical disks rotate in sync to each other. That will create a homogenous magnetic field through the copper pipe.

[@cooperised]

Worth noting that the effect would be stronger with a ferromagnetic material, though of course you do have the problem of the magnets trying to stick to stuff. The phenomenon of "magnetic hysteresis" increases the heat output quite a lot - this is why induction stove tops will only work with ferromagnetic pans.

[@JGnLAU8OAWF6]

Steel backing should work even better since magnetic field wouldn't need to go through air as much, and full aluminium ring to maximize surface area.

[@Santafefrank]

[@tbix1963]

Thanks for sharing your ideas and video. Very interesting and entertaining. Imagine if you had a coil of small diameter copper tubing wound to the same diameter as your circle of magnets. Install it to a fixed point above the magnets and give it a water reservoir and circulation loop. Put a power meter on your motor input and compare the power needed to spin with empty no water tube to a water filled tube and compare how much load it puts on the drill motor vs amount of water and temperature gain.
