Thanks for taking one for the team.
Wow! Almost ordered that junk yesterday. Thanks for the heads up, I got enough unreliable junk bought over the last 20 years
Was one of them shapely as well. 😄
Look it spins, and very nice decoration for your garden.
Thanks you saved me money by testing this.
Love it mate years ago i did the same towing a trailer with turbines mounted high on a steel pole, i had no camera i was just sorting the facts from lies
My biggest surprise was that it didn't disintegrate at anything over 30MPH.
It go somewhere around 7000rpm and I fully expected the blades to come apart. The best made part of the whole thing was the blades lol
you know, it is difficult to not believe that.." it is quite cheap, even if it is not be enough good as they said... it could be a good stuff ..." THANK YOU TO SHOW HOW MUCH A PIECE OF SCRAP IT IS! HOPE EVERY ONE IN THE WORLD LOOK FOR INFO ON YOUR CHANNEL! AGAIN THANKS A LOT!
Funneling the air to hit the turbine only at the front and exit only out the rear would be a big improvement. I picture an upside down bowl over the turbine with an opening at the front and back, kind of like an igloo with a front and back door. I suspect the blades aren't optimized in the least for capturing wind, so that would be the next step.
I was thinking the same thing... wonder if it could be mounted sideways, but on the back of the car/truck to just catch the scoop part of the fans. And what is the max wind speed the unit can handle?
My good sir it’s one of the funniest things I have seen in a while so thank you. Those lantern style turbines are junk, I had one and now it’s just yard art.
Agreed. Wouldn't touch this product with a ten foot pole. Need a thunderstorm to have decent output voltage. Not to mention you wouldn't be able to enter some supermarket car park. A dust collector indeed.
Be interesting to put this in a wind tunnel with a variable fan and wind speed monitor.
Vertical wind turbines have a problem, in that they have to overcome the counter resistance of the blades from 180 degrees on the other side. The only way to overcome that resistance is by using a fixed stator surrounding the vertical turbine, to block wind from the opposing side and redirect that air into the cup side. For a stator just picture a few 2 x 2 boards, angled around the vertical turbine, blocking the opposing side and redirecting that air to the cup side. The stator is essentially squeezing more air into the cup side. You can get by with just one board while testing on your car top. I tested an Apollo 500 watt propeller turbine by mounting it to my truck, and I got my rated voltage at 12 MPH. I did have to adjust the angle of the propeller blades through angled spacers to get that performance. Most turbines are the horizontal propeller type because they are more efficient than vertical turbines.
Look at www.windside.com
May change your mind on verticals
It's amazing how the blades didn't break off from the vibration of the road !!!
if your battery is completely dead it may not take a charge so the wind generator cannot push it in so it will read low and the same if it's full the regulator will not pass power through same with a dead battery the regulator stops it you are probably better doing open circuit test but the regulator can and will stop any output. Also the newer models appear to do a better job going by the reviews
I almost bought one of these. Thank you for saving me from my stupid mistake.
I know Im randomly asking but does anyone know a method to log back into an instagram account?
I was dumb lost my password. I would love any help you can give me
@Hudson Vivaan instablaster :)
@Archie Ronin Thanks so much for your reply. I found the site thru google and I'm trying it out atm.
Seems to take quite some time so I will reply here later with my results.
@Archie Ronin it did the trick and I now got access to my account again. Im so happy!
Thank you so much you saved my ass!
@Hudson Vivaan Happy to help :)
I'd take one of those and rework it, use it for the platform. Thanks for the video.
With a lot of the junk eBay if there's a problem the vendor is forced to accept the return....so this one went back. If I'd have gotten stuck with it I probably would have tried to get retrofit it to a F&P type motor to see if it'd work better with a real stator/rotor assembly.
Would have loved to see 'concluding thoughts'; awesome amount of willingness to try!
I bought one of these because they look cool, I was 100% sure the output would be horrible and it was. I am going to experiment with a variable voltage converter so that I can boost the voltage to somthing useable and maybe get a watt or 2 outta it.
There you go, he did all the test and that crap is crap!!! awesome test sir! you saved us a lot of money on this junk!
You need to match the load impedance to the turbine.
Use a 8- 24VDC input, 200 Watt MPPT standalone (not grid-tie) inverter to convert DC to 120VAC to match the turbine impedance to the load impedance over the speeds and output voltages of the 3-phase alternator of the turbine.
Using a 3-phase rectifier to convert the 3-wire star configuration 3-phase alternator output to dc is OK. Use your 2-wire dc wattmeter betwern the rectifier and the inverter input as before to measure power input to the inverter. Connect a 120vac incandescent light bulb as the load to the inverter output.
This turbine will work, perhaps better than you expect (but may not deliver the rated 400 watts), especially at the high speeds you were driving at which exceed most practical normal wind speeds. But you have to know what you are doing and give the turbine a fair chance to work !
no need MPPT on non pure dc source, rectifier to load or drained battery is good test, you tested it right, you could also create a variable load, its funny these people think ac generators are effective with mppt controllers, it pulsating dc from the rectifiers, its not like pure dc from solar cells
This thing is a well known scam.
I have low voltage output problem. It produce only 8-9 DC volt when connect with a 12 V battery. Do you mean the turbine work only with complete system setup? If so, please guide me. Thanks
Love it. Great job.
Also be wary of Chinese/Ebay solar panels. I bought one that was claimed to be 200W but I measured it at 100W.
Lookong to the output voltage with 10v at 60 miles, as if the generator is for 6V battery. The build seems good, so if you can put a boost converter to test it one last time before throwing it..
This could be interesting if he had checked that the wind speed at the turbine actually matches the car's speed.
Air flow is probably extremely turbulent on the car roof. Almost no turbine will perform well in turbulent flow. That is why they are mounted high on poles away from obstacles!
exactly
I believe the test is a little flawed also. Put a charge controller on it and a load resistor and connect the charge controller to a battery. You will get different results I am guessing
I came looking for a comment like this. Wind speed near the roofline of the vehicle would be severely affected by the slipstream over the windscreen of the car. In a wind tunnel you would probably find the the mounting point on the roof is in the middle of a low pressure zone or an eddy with very low air speed. also any cross winds or tail winds will change the airspeed across the roof surface. This is why a plane can fly into a headwind and stay airborne even though its stall speed is greater than its ground speed.
he should have actually addressed the framerate of his roof camera. When the turbine spin matched a multiple of the framerate, it appeared to quit spinning, but it didn't actually.
You guys are applying the thinking of HAWTs to VAWTs. You can't do that. VAWTs are not as vulnerable to turbulent air as HAWTs. If there is an issue - it's with the generator.It would have been nice with a variable load, as a tired car battery not necessarily pulls large amps when fed.
Looks great!
We have pretty light winds as we are in a valley. We have good solar but looking at adding a small wind turbine to top up the 48v lithium battery in cloudy weather and at night. What cheap wind turbine would you recommend for light winds?
Light wind makes it a bit difficult...that means either mounting it very high up (60~100ft) or making it very large to be able to gather enough wind to make it productive. You're most likely going to be looking at a scratch build and one of Hugh Piggot's axial flux designs would be the best option financially and for performance. Some of the larger companies might also be able to help get you in the right direction...Bergey, for example.
Thanks for this, I was considering one of these to supplement my 200 watt solar setup during the winter months, my setup is not ideal and in winter the sun is too low for the panels to give a reasonable output, looks like I'l have to come up with something else, I cannot go with a larger turbine as space is an issue.
If a wind turbine would help there are some out there that are worth looking into...just not this one. Go through my videos, I've got a couple that have done pretty well...and if you subscribe you'll get notifications of when I do new ones. I try to focus on inexpensive micro turbines specifically.
@@ToysforWatts you want a rutland 914 or 504 etc also air-x wind. Steer clear of cheep chinese junk it will sit in you shed for ever or the bin.

@@davidleebls1874
I have one of these, this idiot knows nothing about electrics or wind turbulence
My unit (CORRECTLY INSTALLED) produces 2.8 amps at 20 mph
Good luck to You! Very good video, at least, even these couple vatts are big surprise, from this garden decoration :) keep up the good work. Also, look at internet shops, there are conventional type turbine for some about 120 bucks shipped. Maybe, is it worth to make testijg for this also.
Brilliant!
Chinese say "Lantern Windmill rated 400 Watts in one day." Or .2777 Watts per minute. Strange thing is, that if you hook up 110VAC LED indicators to them you can get a decent amount of light out of one.
5to8 amps charging 12v battery
When your driving 40 to 70 and stick the hand out you fan feel your hand being pushed with a lot of force, I imagine properly making a wind fan thats able to funnel most of the air into a narrower cavity and the right flan blade design that can increase air drag flow and were looking at a very viable amount of sufficient power to transfer that energy to a back up battery pack, especially if you drive electric vehicles. while your using one, the other one is being charged, and when the one your using runs low on energy, you turn on the 2nd one to continue, as the wind fan generator charges the first one that was depleted. But never charge a battery as its being used because that creates extra load, then the battery can overheat, reducing lifespan, and can even expand and explode.
Thanks for the info
Well done 👍
Big thanks almost bought
Well done! Well done !! Well done !!!: a great idea. Having created the wind, moving the car I recharge the batteries that will allow me to travel forever: a great idea
Could charge electric cars but idea is test wind speed,
thanks for video ! I have same tourbine charge the battery with 150ma .this is rabish not tourbine
Will I have one thing to say the say not to use sold wire on them. It need to be stranded wire
May have worked with LEDs?
thank you for this you saved me some cash :)
How can you measure “watts” with no load?
Who else was waiting for the ratchet strap to get tangled ? I stayed for the whole video.

When you run the 3 wires to the rectifier ( charge controller ) it changes the current to 12 V DC so that it can charge your battery. If you want to run your lights off this system you either need to go from the battery, which is DC to an inverter which will give you 110 v AC and that is what your light need to run. Or switch your lights to 12 v. DC. Another thing. You are using the worst wire to do this application. The electricity runs on the outside of the copper wire. So using single strand wire in a DC application limits the amount of electricity your able to send through the system. After running through the rectifier the wire should be shorter and much thicker as well as multiple strand. Just rule of thumb for 12v DC.
DC doesn't care if the wire is solid or multi strand. As long as it is thick enough to carry the amperage you expect to run through it, and I think that wire looks like a few mm core which is fine for that test. You are thinking of (and yes I had to look it up to be sure) 'skin effect' which does not even come into play till you get to higher frequencies.

sometimes obvious truth can be so funny and entertaining :D
it probably has an emergency brake inside to prevent it from being destroyed by bad weather and your giving it bad weather conditions.
Hey, is your turbine still working?
It's acting like one leg may not be connected. running on 2 of the 3 legs greatly limits the current available from the field strength of the magnets. Check the wires with an Ohm meter, (make sure the turbine isn't spinning) and make sure you see same resistance between any 2 wires.(within 5%) to make sure there are no internal shorts, or, disconnects. You might try using one of the heavy duty six-diode bridge rectifiers you're using with your other turbines. Forget 400 watts, let's try for a more realistic 40 watts. It just doesn't look big enough, to have the swept area to produce any more power than that, at any reasonable wind speed. (let alone, it's rated wind speed)
so it's supposed to be a 400 watt turbine but it produces the amperage of about a 60-70 watt solar panel seems underpowered to me perhaps?
Ha I was just thinking about this
There are several factors that could have caused this outcome. With a dead battery at the end of its life it probably wasn't accepting a charge...nor was there any charge controller connected. You cannot expect any reliable results if you don't know what you are doing. What is the probability that you actually broke off one or more wires when you were pinching them with your calliper? Pretty high I'd say.
You are under the air foil in a vacume move it forward 5 feet so it's a the break of the windshield you will get a very different result but it's still crap the last generation is decent though
It's actually in a high pressure area (according to Ford's aerodynamics testing)....the air where the turbine is would actually be densest/fastest where I put it....BUT I actually sat down and did the math after putting the video together. Ignoring all ideas of whether positioning was responsible for the results, the turbine was spinning nearly 6000rpm at one point and peak open voltage didn't come anywhere near manufacturer claims. There's no way it would reach that kind of rpm on a pole in my field...it really was just a bad stator/rotor combination.
Is there a turbine motor that could replace the one you have to make it work?
Anything is possible but, in general, I don't think it's worth the hassle with this style vane.
I have one of these useless things so how do I improve performance or do I need to buy something else? André
I have not seen any way in which to make it better. I imagine that some come with better stators...mine had very small wire and magnets and very little of either, there was no saving it. I'd suggest forcing a return and refund if you can and buying something else.
Your car will be using more gas because of the drag and weight. Its a tiny amount but so is the power you generate. Also these drag-type vertical axis wind turbines are very inefficient because the drag keeps it from spinning efficiently, perhaps try the helix type.
I don't think he meant to break the laws of thermodynamics 😊
Question is how much higher is your fuel consumption....
What receiver did you connect it to? Or did you forget to connect anything apart from your meter... :s The lights are not rated for the voltage the generator is supposed to output, are they... Put some effort into it next time:S
I want to know how much and how much voltage will come out when RPM is turned on
It was spinning several thousand RPM at times and was making
Dude. The mph on many turbines are 10- 24 mph
(atmosphere wind speed). If you exceed that the safe mode kicks in and dumbs down to protect the system.
No...no they don't. Charge controllers have brakes integrated into them sometimes, but the turbines are just copper and magnets. And when the brakes are on, they don't just stop electricity from flowing, they stop the turbine from turning.
Is there an actual turbine set up that works made in the USA? I wanna do the van life thing & was thinking this would be good to have with solar for gloomy windy days. Any suggestions ppl??
Not many great examples made in the US...there are a few that "claim" to be made in the states but so far every example I have come across has been assembled stateside at best, and have lackluster results. If you truly want it made in America, you'll have to do the making...which is not hard. You can look up axial flux designs and the work of Hugh Piggot...get all your materials here and follow his instructions and you'll have en exceptional turbine.
If you want something off the shelf that you know will work, though, the iSta Breeze i1500 is the most budget friendly consumer grade model that will actually meet or even exceed manufacturer claims.

Dont think I'd buy that kind of wind turbin good way to test it
This sound from the view on the roof is very peaceful.
it can be used for next electric car designs . . a wind turbine
Epic video bro! 🤦♂️
What we need is smaller versions of these to screw on the car when it's windy outside and we are not using our car, like at night, simply to make use of the car roof and the wind.
He thinks he testing wind speeds, but driving 100kmh is tornado, windmill work 10m/s speeds but hard calculation when shoe is measure instrument and bad connection and too long and thin wire needs 6mm2 wire and good battery no dead car battery
Just FYI: there were bulbs missing in the xmas lights.
Thanks for this testing... it seem like the unit is worthless.. 1 solar panel will product more and living with 50 mph winds all the time for spit or two is not good for me.
Seems like it’s sitting in a void .. windshield deflection of air flow ?
It was sitting in the densest possible air. Look up shutter sync.
Did you read the manual ? I have been using this wind generator and it work perfect.
So.... What did you do different than shown in the video?
I'd love to know
Also, you seem sus as your account joined youtube less than a minute before posting this comment.
Who is the producer ?
No label anywhere .
I got a "1500 W" with the 3 wires very thin
and discovered all different outputs have same sizes just different background on add. Is there any international body to report and get rid of all these scans ?
I'm doing a lot of research on where they're all coming from and it seems like there are five major manufacturers of these micro turbines, three of which are contract factories that just make whatever they're told to make according to the specs they're given. In the end the seller's are not the manufacturers and they're the ones making "claims" about production capabilities.
Two of the factories make higher end machines...my 700 watt turbine is from one of these factories.
In the end, though, it's not easy to determine exactly where each machine came from.
@@ToysforWatts Thanks for reverting.
OK, I will try to see if it works. Does it matter how you connect the 3 yellow thin cables from the generator to the 3 black on the regulator? No marks anywhere.
Of course red and black goes to battery.
I turned the generator by hand and got about 12 V. How can I bench test it to check how many watts it produces.
The add said 1500 W - so maybe 150 W
ha ha with those 3 thin threads.
I am bugged about China churning out so much poor stuff. I got a "quality GPS tracker " not worth the wrapping. No more poorly made Chinese stuff here.
@@janerikrendahl4161 Are you taking account of the 3-phase output, and properly rectifying it before taking readings through your meter? difficult to see your wiring layout in the video, but 3-phase rectification must be done correctly (apologies if you already know this).
Elon Musk..Wait a minute..let`s add that to the cybertruck
It would be ok if it was charging super caps and powering garden lights
maybe you need more resistance and a bigger motor that kicks in when you achieve say 25 mph and chokes it at 35 mph with the use of a gear and clutch system.?like an automatic gearbox..creating something that spins too quick may not work like we think it should and im no scientist.
I think theres lot of people like me thats mechanically inclined and been interested in wind and solar, but never studied Amps and watts to understand what we need for our projects.
I have a 20ft camper on land that I bring a Marine battery to run a couple lights at night mostly on weekends or a week at a time. I thought something like this would be good to keep my battery charged all times so I can leave my battery there becouse i bring it home to charge it.
Does anyone have any recommendations that works for me? I dont go solar becouse of shade. The battery would have time to charge for at least 5 days before I'm back. I thought something like this would be nice becouse its small more hidden for what i want. Any ideas is welcome.
Thanks for the good video.
What size battery are you charging and what kind of wind can you rely on? You say no to solar because of shade, but shade makes me think you're around trees and that tends to interfere with wind turbine operating also.
@@ToysforWatts right around 1000 CCA marine . Its about a truck battery and a half. Its heavy. I bought it at walmart 12 years ago. Biggest one they had. Still good. I do plain on up grading battery I dont have it by me to give information on it. But I do plan on upgrading battery. I don't use a lot of power battery is actually lasted 2 weeks every night for couple hours before I recharged it.
I am around trees in a planted Pine Forest. Thought I would mount on a 35 foot pole trees are only 20- 25 ft high. I do get good wind above tree line real consistent. Lake Michigan winds.
You should have blocked half of the turbine from the wind so only one side gets the wind. It would spin it more consistent then if wind hit it directly the same on both sides of it. Like a water wheel only being pushed by a force in one section of the wheel, the same with the wind. It should only get the wind on one side of the wheel for maximum spin. Try that. :)
I commented the same thing i hope he listens and tries again
Yeah but what for? Real world wind conditions will be similar. The wind direction changes so having one side blocked would make it worse in the real world. Obviously here it would make it better…
U can not use that type of wire dc current will not travel thru solid wire. Try 10g weld wire and then it will work. Has to be stranded wire
He confused watts with kilowatt-hours on the meter readout. Should have calculated the watts by multiplying the amps X volts instead of reading the kilowatt-hours. Anyway, it obviously needed much more wind to get going, so this is not going to be practical any way you cut it. Thank you for showing us the actual performance!
Where would you place the failure to work as advertised, the blade design, the motor, or it's just an all around piece of crap? What would happen if you took the blade portion and attached it to a car fan motor, Robert Murray Smith used one from a Nissan Micro in one of his videos, but it wasn't with a lantern blade configuration. I'm in the process of building a Vardo/sheep herder trailer and planning on solar panels placed on the length of the mollycroft, and being a big redundancy fan thought a small wind turbine on a separate system would be the ticket, the lantern style blades looks as if it would best option
In this case it had very small wire and a very small amount of it. The magnets were also small but could have been serviceable with a better stator. It was just built far too lightly.
It's the 20 ft of extra wire and the fact that he used single strand instead of multi-strain mc4 that carries more current. Change the wire lose the excess footage and redo the test
Lol, All I can say is "paper weight"!! Good test though!!
Good concept, but a few flaws I Can see . The turbine is not actually getting the amount of air speed you are driving, as it is not in clean air and the point of compression has changed due to the aerodynamics of the vehicle. Maybe put it on the hood instead of the roof
The hood is actually a low pressure area. The highest densities around the 2005 Ford Expedition are directly in front of the grill and about 12" behind and above the top edge of the windshield. Air has to compress and go up and over the hood...it's not a particularly aerodynamic vehicle and air does not flow cleanly around it. I chose top center because it was the densest air I could safely get. Trust me, at the one point the turbine was running between 6000 and 7000 rpm...the location exposed the turbine to more wind and rpm than it would ever get during reasonable use and still produced next to nothing.
But all those lights you’re trying to use as loads appear to be 120V AC Lights, and the machine is supposed to output 24V DC, right? And your charge controller is looking for a battery, to charge, right? You may be right, but we cant really know for sire because your loads aren’t the right loads to use... you need to connect the charge controller to a battery, then the battery to an inverter, then plug your lights into the inverter. Or juat use a dump load resistor.
ANY load should have drawn some wattage out of the turbine. A 120v AC lamp would act like any other kind of resistant load. The take away from the experiment wasn't suppose to be "well it turns out this allegedly 400w 24vdc turbine can't run a 120v 500w work lamp"...the take away is that the turbine was not producing any usable power regardless of wind speed. I could have built the perfect system and there still wouldn't have been enough copper and magnet inside to make it work.
Toys for Watts what you say is true if you connect the output of the generator directly to the lamp, but not it it’s a charge controller. If that’s a charge controller it won’t put current to a lamp unless it’s a designated lamp connection. A charge controller is sensing the voltage level of the battery it’s charging and won’t send current to a short circuit and won’t send more current than what is safe for charging the battery. The current exiting the charge controller is dependent on the battery level, that’s why connecting lights to the output of the charge controller won’t work.
I believe your cars aero dynamics were interfering with the wind. It seemed to spin better at 30-40 mph. It probably needed to be 5 feet or so above the roof. Nice effort...

Optical illusion. The frame rate of the video causes a speed up then slow down as the frequency match up and diverge. The same as videoing a propeller of an airplane. André
Trying to run a 120 volt lamp on about 12 volts was never going to work.
Especially because it's 120 V AC an the output from the charge controller is DC...
those Lantern turbine has electric brakes on them when spin too fast they slow down
Could they have invented a more inefficient wind turbine than one?
THANK YOU I was thinking to order its claiming 4000 watts the liars
Its crazy, they range from 800w to 4000w+! (exact same models /price)
This should be reported as a scam.
Chinese ethics = $$$$ pay suckers
Funny thing is that in his previous video he said that it is a 400W unit just before he started pinching some of the wires inside with a calliper to measure them. I cannot see that the manufacturer would have been this far out... and apart from the clueless manner in which the test was conducted, the chances are that he severed some of the wires when he had his calliper in there and the alternator was running on only a few windings.
Link broken for the turbine
Real nice test! Would be nice if you had also a windmeter on top to see what the m/s was on the speed you drove and the amound of whats
You can calculate it.. It's not that hard
Do you recommend it?
No. It produced virtually no power whatsoever.
@@ToysforWatts okay, thanks for your answer. I also have a vertikal Windturbine and also the other ... But I also think that vertikal Axis ist just expansive waste. Look at my Channel If you where interestet, IS IT OK when i Link your Video under my newest Upload?
Feel free to share the channel wherever you like, the more traffic I get the faster I can get to a point where I can play with and review more of these things :)
Rubbish but nice decoration and talking point with neighbors.
Am i only the one that waiting for that thing to fly away
I think the design of the turbine part is fine it must just have a total rubbish generator. I think if you bolted that rotor to a dc electric scooter motor or anything similar, you would get a much better result.
No way. That design is absolute rubbish. The air that gets sliced into by the leading edge creates a fckd up vortex on the trailing edge causing loss in efficiency.
@@haywoodjablome440 yeah i get that but easily fixed with wid deflectors focusing the wind to only catch the trailing side.
brought one 07/23 worked ok on my caravan until i got it up to 110 km blade broke off cost more to replace blade than to buy a new one
I will be honest here when saying the Chinees make brilliant watt meters.
Everyone did notice the meter reads what is current and he was stopped while showing us. The battery went from 10 volts to 11 volts so it was receiving a charge. cant say how much because we cannot see meter while vehcile is moving.....Inaccurate testing of this....
It wasn't suppose to be an accurate test. It's easily the least informative test I've done and was only done to demonstrate that it was simply incapable of coming anywhere near the seller's claimed outputs. You can see the break down of the generator in the link below...too small of wire, not enough of it, and tiny TINY magnets. Producing anything at all was impressive in a way. czcams.com/video/H7_UFuM9ZZY/video.html
So to do any good you would need a wind speed between 35 to 40 mph. Not good in my opinion.
So the conclusion is that the blades spin fine but the power is low? And the reason it didn't spin when you drove faster is because of a brake function? That's why your meter was blank?
It was actually spinning very, very fast the whole time. When it looked like it was spinning slowly, backward, or not spinning at all it was what's referred to shutter sync. Search CZcams for shutter sync, you'll get a much better explanation than I can give and some awesome examples of like helicopters that seem to have completely motionless blades while flying. It's pretty neat :)
Power was low because the wire in the stator was very small, there was very little of it, and the magnets were weak and small. It was a very poor combination for a wind turbine.
@@ToysforWatts thanks for the explanation!
I feel like a smaller fan or fanss could work if it was funneled in aerodynamically to the sides of the vehicle.
Defintely dont trust any numbers from Them but something is wrong with your battery or your connection to it... The thing has to get at least 200w but I've seen other tests that give 400.. get a multimeter and another battery connected to an inverter, connected to a load.. Scrape the gunk off the battery terminals or try new battery
Maybe your trying to run a 110 volt light set off of your 12 volt system. That doesn't work.
His testing is definitely faulty
The top of vehicle camera seems to show the turbine slow and stop at higher speeds. Suggests turbulence from the vehicle or set up or the turbines internal brake system for high wind speeds
Good to know. Not a viable option, even in windy Twin Falls, Idaho.
