I can't begin to tell you how happy I am to have found your channel Mr. Smith. You're a modern day Mr. Wizard providing conceptual physics & engineering lessons in practical applications~
He does a really good job of explaining the stuff. With this one, you can print the tinkercad files, throw in the coil, a couple bearings, the magnets, and a shaft. He talks about this over this video and the one a few videos back he referenced in this video. He's laid it all out. Over the course of these two videos. Honestly IKEA could use a youtube channel where they walk you through how to construct the things. I'd prefer that format
What I love most about the serpentine coil is how easy it is to make. Even if it were less efficient, it would still be a huge upside that a child can build them.
Once you have the design, protopasta makes an 80% iron infused PLA that has a permeability of 5-8. Making the stator and cover out of that would further improve the flux change the windings would see.
This is basically what I have been working on and commented on an older video. A little longer coil and stronger magnets. So cool to see you doing the same thing and bathe same time basically. Keep up the great work!!!
Mr. Murray-Smith, what a fabulous resource you are for ideas and things to ponder and consider. And it's tons of fun watching you and seeing your enthusiasm! Keep up the great thinking and tinkering!!! The world could use more people like you!!! God bless you, sir!
I suggest (again) inserting a steel cylinder inside the rotor. This will magnetically connect the N/S back ends of the magnets, strengthening the magnetic field intersecting your serpentine coil. You will have to apply more torque but will get higher voltage out, which makes the generator even more effective for its size.
Will it make a difference if the steel cylinder touches the magnets? or should the magnets and steel be separated? If it should be separated, does the distance from the magnets to the steel have an effect on the efficiency of the generator?
Great idea :) 3:05 if you make 3 coils to install them in 3-phase configuration, you would be increasing the horizontal length, which we avoided with the serpentine coils 😅
Have you tried using halbach arrangements instead of NSNSNS? Isn't the best magnetic field the one with the most cross section going through the wires perpendiculary? NSNSNSNS looks like small circles, the opposite of the serpentine coil's objective How to not waste the part of the field that is perpendicular to the surface of the magnets? And the part of the field that's pointlessly in the middle of the rotor? Maybe it's only relevant in bigger rotors so that the geometry of the rotor is closer to being flat(larger diameter), or not at all But you've optimized for the best electric field reaction to the accelerated magnetic field, but what about optimizing the magnetic field itself? I'd love to see a 2d halbach array using many small magnets, maybe offset/intercalated so that the resulting magnetic field is like a larger diameter cylinder parallel to the surface of the magnets/rotor. I really hope there's something useful around this idea
Instead of an outer sleave you should have another cylinder of magnets. Gauss rating is at the surface of the magnet. The further away the copper from the surface of the magnet the greater loss of gauss. To combat this you need to force the field lines of the magnets to travel to another magnet. This will improve efficiency by creating a magnetic circuit. Double the magnets for two rotors and one stator.
@@Unpopular_0pinion well just being able to overlap the coils and fit more copper into the stator is one major advantage in the serpentine's case, then there's the point that three-phase generators can be very easily converted into motors with a controller, and finally I'd say a three phase generator if wired correctly should be able to produce a much higher frequency of ac current with the same speed of rotation.
@@Unpopular_0pinion not generally it's just able to be used in a wider variety of situations without needing extra electronic components. Being able to take up the empty space with more windings does allow for more power out of certain configurations however.
This an absolutely brilliant video, This also makes an most excellent motor when ran (can use hall effect sensors or reed switches ) as such. A man named John Bedini designed a motor called a "window' motor , and i made several of them and realized they make excellent alternators, when ran as such. There is no cogging , which is nice , and its easy to get good current out at low rpms.... The serpentine coil makes it all so much easier.
A great simplification of a very complex topic. I'd like to see a video on low RPM generators - would it be possible to get more than a couple of watts out of a DIY low rpm (100-600rpm) gen by using larger magnets, bigger stator cores etc (with no gearbox required) or is it always preferable to use higher RPM in an AC gen? Keep up the quality stuff !
great question dude! firstly yes, technically you can reap greater power by increasing magnetic field and stator core size but it also depends on what the application is. if your trying run appliances, some may be fine but other more complex electronics are tuned to function at a certain Hz (frequency) which is determined by the rate the the N and S magnets push and pull the electrons back and forth in the circuit. so rpm determines the Hz. but if your application was energy storage, than you can repurpose the energy as it suits ;)
Very cool. I am looking at small, pedal-powered generators for a pedal car project. I know using a generator and motors will be far less efficient than a chain drive. This ought to help me save some of that efficiency. Thanks!
I am just amazed that his design has not been used way sooner Robert. Know for sure that now a many people will make the same method to make wind energy machines. Depending on location, this would make one self-sufficient and not care about cost of energy. Especially since electricity today is just going through the roof on ones electric bill. Nice work Sir. Peace vf
Robert you have inspired me to make these coils, though I have taken it a step further . I own punch presses and do tool and die work. I have built tooling which will form right angle serpentine coils out of 1/4" or 3/8" solid thick copper. No wrapping of single strands. The die is a progressive die set and the serpentine is taken up on a larger computerized machine coil, normally used for metal stamping of parts. Can cut to length making the diameter nearly any size wanted. Willing to supply samples for anyone interested. Keep up the good work.
Hi Robert, Your latest video is interesting. In my experience not enough is given to the magnetic circuit. Your generator would probably give more output with an iron rotor and a surrounding iron casing.
Great project, hope you release the files at some point. I would love it if you tried to short out the coils and give the generator a spin whenever you measure the open circruit voltage, the braking can give an idea of how well the generator performs.
What would happen if you made 2 stators, one on the inside of your coil and one on the outside of your coil in the same orientation? Would that increase your energy density any? Perhaps test layering coils and stators around the same axis to see if that will increase your power density. See if 2 coils can power the third to create over-unity output?
This is why you pass information down from one generation to the next and this is why its a good idea to actually engage in historical research and history instead of neglect it and pass it off as outdated, you will not imagine the amount of stuff we have lost due to ignorance, This is something that would better our future use of better more effective motor generation

If you made the magnets horizontal in a radial direction and made the serpentine coil flat in the horizontal direction you can bring the coil closer to the magnets. You can also stack the magnets and coils making a layer of magnets and coils alternately. You stack them as high as you want to produce the output you want.
Hi Robert. Great video, thanks a lot! Just to get this right... This now is not three phase? It only has three separate coils that you can arrange either in parallel or in series? And how would I arrange three serpentines to act as three phase generator? Have them run down in one slot and leave two empty before coming up again, or have each coil covering a 120 degrees segment of the stator?
Very nice. I'm looking forward to seeing a purpose built darwin to match this ... Looks like the more depth on the coil the better. Magnets to match. I'm stuck at the magnetic rotor stage, not having access to ceramic bearings at an affordable price. I'd happily accept any donations here in India ....
Fantastic well done Mate. Remember the graphene ink coil? Any chance you can build a serpentine gen with one, isnt your ink more conductive than copper? if you coat a thin fishing line with ink let it dry then paint it with resin?Then wind your coil? Please pretty Please??? And lighter than copper.
I love your channel! I am not sure it has been mentioned before you could get more flux through the coil if you returned the magnetic flux on the rotor. You have a high reluctance path from the back of the magnets to the front of the magnets so you lose half the magnetic field that comes from the back of the magnets. You could build a low reluctance path to return the magnetic field from the magnet face that faces the coils to the back of the magnet by building the rotor in the shape of a cup made of magnetic material. The stator would fit inside the cup. The rotor cup would spin around the stator. You need the rotor in a cup shape so you don't make eddy currents - makes things a bit heavier and harder to build but you should be able to double the flux, hence the efficiency. Carry on!
Hi I have been watching your material for quite some time now, always enjoyable and informative thank you. If the serpentine coil is more efficient why do you suppose it hasn't been adopted in commercial alternators and motors. Just a thought
Awesome as always Robert! So in this configuration, would one turbine twice the length be more efficient that 2 turbines at normal length due to minimized bend points? When would you reach effieincy saturation purely from extending the straight section length?
Hello, great video's love em! Can i ask how you secure the magnets to the plastic? Glue/tape or something else... Also if you use stronger magnets will that effect the watts/amps output, say N52 magnets?
just a question ... could be used some kind of cvt transmission to optimize the rpm and power got from a wind turbine, and protect it from strong winds? Cheers
Aren't commercial alternators, like used in cars, established technology in terms of mass production, friction losses (eg good quality bearings), using a light coil instead of heavy magnets etc?
More stimulating information. But I have to point out one tiny error - The serpentine configuration does not give a higher ration of copper wires in the vertical plane to the horizontal plane (tops/bottoms) over a standard coil configuration. But that takes nothing away from the other advantages of the serpentine configuration.
Could you maybe also tell how many meters/grams of wire goe in a certain design? I would like to experiment with this and am looking to buy enameled copper wire. It's not cheap so would be nice to know if I need to buy 500grams or better 1000gram spools (of maybe it is a lot less used in such a generator) ?
Is it “right-anglesness” or the length of the wire that increases efficiency? Because wire in serpentine configuration is longer at the shallower angle than at the right angle.
How much more power would making the stator and magents say around 6 foot in length in a long tube, like this little one you made? to power make a vertical blade setup that would be secured to the shaft (if shaft is pointing up), and the vertical blade setup surrounds the 6 foot tube from top to bottom? a simple flat bearing at the bottom can secure the bottom of the vertical blade setup. Hope that made sense, as these vertical blade wind turbines, i always found it odd that they use one small looking generator instead of expanding that generator vertically within the blades. probably has been done and it didn't make much energy? if it needs more torque to spin. just increase the vertical blade design, granted at some point you'll have 4foot wide blades, but would be an interesting experiment as i haven't seen any youtube vidoes doing that.
follow up to my recommendation in another video. pu 12 soft iron fins in the middle of the coil that I recomended, as well as 12 fins offset half way outside the coil.
Hey! An interesting idea to let this motor deliver more watts (in higher wind speeds) without going over the current limit of the wire would be to have a circuit that has a sort of adaptive resistance or reluctance to limit current while allowing the voltage to climb, making a sort of varying voltage, constant current generator. This would obviously be limited by the dielectric strength of the wire insulator, but what are your thoughts? Maybe combine elements of this idea with a computer controlled magnetic gearbox to maximize output sort of like knee-point tracking in solar?
Robert, i watched the video where you say you can use a mosfet to induce maqgnetism in a electro magnet. In another video you said the longer copperwire the higher voltage, the wider it is the higher amperage. So i guess we agree that the more copper used in weight the more watt will you get. But you might be able to create a strong magnet field on your electromagnets, with just very low input watts. So do you really need a wind turbine, to make 6watts?
I love your work and enthusiasm hurry up and fine tune this and issue the ultimate window generator. Each video I can seeing you getting closer can't wait for the day you drop the final design plus cad designs legend keep plucking away
Before I watched this video I had an idea about how you could fit this sort of thing in a downpipe. The diameter looks about the same, so the idea is to have the serpentine coil just inside the downpipe and a hollow rotor vertically mounted with the secret ingredient of a fan or archimedes screw inside the rotor so that rainwater turns it to generate electricity. OK, some losses due to structure to hold the axle in place, and probably a conical shape to cover the coils and direct water to the centre. Consider that water is denser than air. Well, something to think about.
Just had an Idea you might enjoy: A suspended water tank swaying in the wind could be fitted with a small tube, and a few tesla valves at the bottom, and would act as a rectifier pump.
I have used 20mm square x 10mm neodinium magnete n52. What if i wound up down up over each magnet and so on. I would effectively have 3 vertical sets of wires passing each magnet.
How would one determine the optimum ratio of the copper wire used to make the 180 degree turn from north to south as opposed to the straight- line generation sector of the generator thru increased axial length to be the most efficient in terms of cost to returns; would the magnets be the determining factor?
You can increase the output by doping the stator with iron powder. Also you can angel your magnets having 2 like poles pointing toward each other and increase the magnetic field strength. Tesla gives heaps of info he ran 42 poles or more. But good place to start.
Robert, are these files available on Tinkercad yet? I looked in your designs and couldn't see it. Thanks for all your work. I have printed 8 ugrinsky blades inspired by your video. It runs in the slightest breeze and I intend to use it to heat a 12v element in a radiator.
Thanks for your bold claims" 😉 Keep 'em coming! Switch from a joule thief... Eddie current...magnetrons..capacitors cascading... tilting leverage...gravity...... ideas ..ideas!
I was thinking about this and what if instead of, or in addition to, rotating the 12 magnets at once, what if we rotated the magnetic field in each of the 12 positions? What I am imagining are two coils, an inner and outer coil, and 24 magnets in alternating alignment. As an example each set of two might be say N/S then S,N, with coils on each side. Then something that rotates the actual magnets. I am imagining a gear-like system where every, just as an example, 1/12th of a turn is effectively equal to one full revolution of two of these.
Think I'm going to have to watch this several times,, the information about the angle of the coil and opposed to the polarity of the magnets,, as I have a bunch of microwave magnets,, and I'm wondering how wide I'll have to space my wire crossings so glad I don't have multiples influence at any one time
Hello sir. Came into your wind turbine series rather late and find it fascinating. Now watching your other videos and have subscribed. What are your thoughts on the Halcium Powerpod which I am certain you are well aware of? Cheers
Have you talked about axial flux motors before? I saw someone use those motors for a wind turbine generator, id love to hear your opinion on that. Love your channel thanks a bunch!
Hey Rob nothing wrong with sque the magnets to the same angel as coils lol lol cutting it at a small angle will give the best results so sque both one a just a little more than the other the out put goes down a touch but less force to turn goes down quicker

Hi Rob thanks for answering the wire size, I saw someone on the internet creating their own serpentine generator and he was saying the creating a larger magnetic north by having 3 North's then 3 south's etc etc produce a larger field and hence a larger voltage, what's your thoughts
i don't think it will help much - you need a changing magnetic field and it need to change for each length of wire that goes through it - if you have a broader field the field changes more slowly with respect to rotational speed - or at least that's how i see it - but i could be wrong
You should be able to increase the useful Flux and the power density with a halbach array built using two levels. If the magnets have magnetic fields oriented along the shortest length --assuming the same magnet shape-- then you could use the 3d-prints as--is, alternating North, south radially; if you then modify the magnet holder (is that the armeture?) so that a second ring of magnets are inboard of the exterior ring and can be oriented to make a halbach array. (IE, every north of the inner ring is oriented annularly towards a south of the radially oriented outer ring.) Thus, with only a minor modification, this design should be able to double or triple the usable magnetic Flux: twice the magnets with a field shaped into the used volume. The magnets are in the center, right? I'm suddenly forgetting the assembly pattern. Regardless, the above comments assume the magnets are internal of the coils. The described geometry would have to change (though only slightly: the radial and annular componets swap) if the coils were within the magnet housing.
Can you demonstrate adding multiple generator modules to same axle. Would it produce more watts by adding more coils and magnets to same axle. Or would the conservation of energy with increased inertia of the added modules maintain same ratio of input and output power. Thank you.

For something this size, throwing a $2 buck-boost convertor on it after rectification would work just fine.
Hey Rob, are you using solid wire? I see on the web that twisted wire will reduce electromagnetic power.
Absolutely brilliant robert you never cease to amaze me!
just a question ... could be used some kind of cvt transmission to optimize the rpm and power got from a wind turbine, and protect it from strong winds? Cheers
Great video, thanks. How's the stopping smoking going?
Awesome stuff Robert... Has always!
Thanks Robert another informative video.
The voice of Top Gears Jeremy Clarkeson. love it
Aren't commercial alternators, like used in cars, established technology in terms of mass production, friction losses (eg good quality bearings), using a light coil instead of heavy magnets etc?
How on earth do you add two more coils?
More stimulating information. But I have to point out one tiny error - The serpentine configuration does not give a higher ration of copper wires in the vertical plane to the horizontal plane (tops/bottoms) over a standard coil configuration. But that takes nothing away from the other advantages of the serpentine configuration.
Could you maybe also tell how many meters/grams of wire goe in a certain design? I would like to experiment with this and am looking to buy enameled copper wire. It's not cheap so would be nice to know if I need to buy 500grams or better 1000gram spools (of maybe it is a lot less used in such a generator) ?
Is it “right-anglesness” or the length of the wire that increases efficiency? Because wire in serpentine configuration is longer at the shallower angle than at the right angle.
How much more power would making the stator and magents say around 6 foot in length in a long tube, like this little one you made? to power make a vertical blade setup that would be secured to the shaft (if shaft is pointing up), and the vertical blade setup surrounds the 6 foot tube from top to bottom? a simple flat bearing at the bottom can secure the bottom of the vertical blade setup.
Hope that made sense, as these vertical blade wind turbines, i always found it odd that they use one small looking generator instead of expanding that generator vertically within the blades. probably has been done and it didn't make much energy? if it needs more torque to spin. just increase the vertical blade design, granted at some point you'll have 4foot wide blades, but would be an interesting experiment as i haven't seen any youtube vidoes doing that.
Where do you source your magnets?
Also a BOM would be awesome for future projects
Great vid 👍 thank you 👍
follow up to my recommendation in another video. pu 12 soft iron fins in the middle of the coil that I recomended, as well as 12 fins offset half way outside the coil.
Super interesting Rob, thank you
Looks like a neat wood working project for fun if not function.
Any idea how to get the magnets?
Hey! An interesting idea to let this motor deliver more watts (in higher wind speeds) without going over the current limit of the wire would be to have a circuit that has a sort of adaptive resistance or reluctance to limit current while allowing the voltage to climb, making a sort of varying voltage, constant current generator. This would obviously be limited by the dielectric strength of the wire insulator, but what are your thoughts? Maybe combine elements of this idea with a computer controlled magnetic gearbox to maximize output sort of like knee-point tracking in solar?
Robert, i watched the video where you say you can use a mosfet to induce maqgnetism in a electro magnet. In another video you said the longer copperwire the higher voltage, the wider it is the higher amperage. So i guess we agree that the more copper used in weight the more watt will you get. But you might be able to create a strong magnet field on your electromagnets, with just very low input watts. So do you really need a wind turbine, to make 6watts?
I love your work and enthusiasm hurry up and fine tune this and issue the ultimate window generator. Each video I can seeing you getting closer can't wait for the day you drop the final design plus cad designs legend keep plucking away
Before I watched this video I had an idea about how you could fit this sort of thing in a downpipe. The diameter looks about the same, so the idea is to have the serpentine coil just inside the downpipe and a hollow rotor vertically mounted with the secret ingredient of a fan or archimedes screw inside the rotor so that rainwater turns it to generate electricity. OK, some losses due to structure to hold the axle in place, and probably a conical shape to cover the coils and direct water to the centre. Consider that water is denser than air. Well, something to think about.
Excelsior! Optimization in all regards! The goes Win, Place and Show!
Just had an Idea you might enjoy:
A suspended water tank swaying in the wind could be fitted with a small tube, and a few tesla valves at the bottom, and would act as a rectifier pump.
Awesome work! Really amazing !👍👏👏👏👏👏
I have used 20mm square x 10mm neodinium magnete n52. What if i wound up down up over each magnet and so on. I would effectively have 3 vertical sets of wires passing each magnet.
Thank you, Robert.... it is interesting...!!!
That gold globe in the background cracks me up....
How would one determine the optimum ratio of the copper wire used to make the 180 degree turn from north to south as opposed to the straight- line generation sector of the generator thru increased axial length to be the most efficient in terms of cost to returns; would the magnets be the determining factor?
You can increase the output by doping the stator with iron powder. Also you can angel your magnets having 2 like poles pointing toward each other and increase the magnetic field strength. Tesla gives heaps of info he ran 42 poles or more. But good place to start.
Robert, are these files available on Tinkercad yet? I looked in your designs and couldn't see it. Thanks for all your work. I have printed 8 ugrinsky blades inspired by your video. It runs in the slightest breeze and I intend to use it to heat a 12v element in a radiator.
Thanks for your bold claims" 😉 Keep 'em coming!
Switch from a joule thief... Eddie current...magnetrons..capacitors cascading... tilting leverage...gravity...... ideas ..ideas!
is that a generator, or an alternator?
I was thinking about this and what if instead of, or in addition to, rotating the 12 magnets at once, what if we rotated the magnetic field in each of the 12 positions? What I am imagining are two coils, an inner and outer coil, and 24 magnets in alternating alignment. As an example each set of two might be say N/S then S,N, with coils on each side. Then something that rotates the actual magnets. I am imagining a gear-like system where every, just as an example, 1/12th of a turn is effectively equal to one full revolution of two of these.
Think I'm going to have to watch this several times,, the information about the angle of the coil and opposed to the polarity of the magnets,, as I have a bunch of microwave magnets,, and I'm wondering how wide I'll have to space my wire crossings so glad I don't have multiples influence at any one time
Good job 👏 👍
Great video Rob🎉
Hello sir. Came into your wind turbine series rather late and find it fascinating. Now watching your other videos and have subscribed. What are your thoughts on the Halcium Powerpod which I am certain you are well aware of? Cheers
Have you talked about axial flux motors before? I saw someone use those motors for a wind turbine generator, id love to hear your opinion on that. Love your channel thanks a bunch!
Keep these great videos coming.
Hey Rob nothing wrong with sque the magnets to the same angel as coils lol lol cutting it at a small angle will give the best results so sque both one a just a little more than the other the out put goes down a touch but less force to turn goes down quicker
if you have two tuning forks of the same frequency if we hit one dose the other start singing dose the second one slow the first ones singing water is called ice liquid steam maybe plasma if in right con but are they all water do you make a coil sing but electric dont go though air but it will if plates are very close across the two lines dont work and there is diff in caps laden jar also some things take what magnitizem amps they need others will act like a hole with no bottom until so hot they blow those are the fun ones to tinker with the ones of old in glass under vacuum dont blow as easy of the sold state the best to play with is the harder to find like the diodes with cool metal inside resistants not always a loss there is a almost perfect way to build a inductor ac resistance and dc resistance is not the same period!! another thing if we know the distance between two corners of a triangle and know the angel of another could we make a close estimate of how far up our drone or kite airplane or any thing else is the human eye can not see detail that far away definity impossible to see detail at say 200 to 250 thousand miles up but a drone battery would die before that hell is the moon not 244k miles away now that would be one hell of a battery if we was flying a drone over the ocean it would disappear from bottom to the top because of a thing called vanishing point the triangle from our eye to the drone "looking like setting on top of the water from our view" back of across the water to our feet from feet to our eye makes up this elongated triangle the more elongated the less light can reflect back to our eye the bottom of our drone will disappear first because of this them if we keep going it all will disappear we will need a good zoom lens to bring enough light back in to see it again no one has ever seen a boat go over the carve lol did it truly go over if zoom lens bring it back over that carve same thing with the sun lol lol before you parrot test YOURSELF the foolish is where you find the truths no one needs to know you was foolish enough to test instead of parrot others lol rob has to know this stuff i am not writing this to him no one wants the never ending onslot of insults by tring to show some one truth
What does the waveform look like?
More like a square wave or more sinusoidal?
Hi Rob thanks for answering the wire size, I saw someone on the internet creating their own serpentine generator and he was saying the creating a larger magnetic north by having 3 North's then 3 south's etc etc produce a larger field and hence a larger voltage, what's your thoughts
i don't think it will help much - you need a changing magnetic field and it need to change for each length of wire that goes through it - if you have a broader field the field changes more slowly with respect to rotational speed - or at least that's how i see it - but i could be wrong
@@ThinkingandTinkering
Ah i see thanks
A silly question would litz wire work as well less well or better ?
Exactly what do you mean by removing the top or the bottom (at around 50 seconds or so)?
I love your content keep up the good work!
You should be able to increase the useful Flux and the power density with a halbach array built using two levels. If the magnets have magnetic fields oriented along the shortest length --assuming the same magnet shape-- then you could use the 3d-prints as--is, alternating North, south radially; if you then modify the magnet holder (is that the armeture?) so that a second ring of magnets are inboard of the exterior ring and can be oriented to make a halbach array. (IE, every north of the inner ring is oriented annularly towards a south of the radially oriented outer ring.) Thus, with only a minor modification, this design should be able to double or triple the usable magnetic Flux: twice the magnets with a field shaped into the used volume.
The magnets are in the center, right? I'm suddenly forgetting the assembly pattern. Regardless, the above comments assume the magnets are internal of the coils. The described geometry would have to change (though only slightly: the radial and annular componets swap) if the coils were within the magnet housing.
Could you use ProtoPasta Rustable Magnetic Iron PLA to direct the magnetic flux through the coil to increase output?
Can you demonstrate adding multiple generator modules to same axle. Would it produce more watts by adding more coils and magnets to same axle. Or would the conservation of energy with increased inertia of the added modules maintain same ratio of input and output power. Thank you.
Wouldn’t this do the same as a large diameter traditional circular coil with lots of smaller magnets in same p/n configuration?
I want a 7 kw with a 30amp max output just like the one u can buy to run a house. How big do the magnets need to be
How are you planning on TURNING it is the more important question. That's a big generator.
