@@RomanoPRODUCTION there are many inexpensive brushless motors to match the exact needs. Match the motor kv to the expected rpm, and you can have direct drive.

Comparing both wind turbines output was fine, but while you gave a cost for the commercial, we didn't get to see an estimated cost for the diy project. A cost per watt for both for both would have been very usefull, and likely a major decesion factor for many. 😊 And lastly, a better test for 2 turbines with different blade lengths is to have the same wind blow across the entire surface area of the blade. Maybe take a box fan (or four), and make wind tunnel.

Man, the design creativity in that 3d printed turbine is crazy! Very cool of the creator to release it. Too bad wind is nearly useless around me, but around a big lake or ocean I'd totally build my own.

I do believe in the power of a DIY project. It gives you the opportunity to experience and improve the concept. Your DIY wind turbine can be greatly improved. Don't give up!

Some grease on the moving parts might help regaining some lost power as electricity, i think. And the design is mechanically brilliant but, maybe keeping it simpler and finding a way to make a lighter propeller would help a lot.

I came to the same conclusion. Wind power doesn't scale down: To be practical, it must be huge. The power produced is proportional to the cross-sectional area, so if you make your turbine twice as wide you get four times the power. It's also proportional to wind speed *cubed*, so you need to mount it at some height to get a good wind flow. Photovoltaics are linear in scale: Spend twice as much on panels, get twice as much power output.

@@jklmnpqrst It costs less than four times as much. So the bigger you build your turbine, the better your cost-per-watt gets. The cost of building twice as big is usually less than twice as much too - the blades are cheap, it's the bearings and support that make most of the cost. The economics of wind power are just not in favor of small-scale generation. The rapid fall in the cost of wind power generation in recent years is largely just due to the introduction of bigger and bigger turbines. GE has a model with a 220-meter blade diameter! Those things are around the height of a seventy-story building.

@jakegarrett8109

4 жыл бұрын

Filament I buy is about $10 USD per killogram (so about $5 per pound). Since these don’t really need to be solid you could save some weight but even assuming it’s solid then that’s like maybe a pound of plastic. **Technically I rarely pay over $8 per kilo shipped to my door, but I also don’t care about color so if ugly puke green or fluorescent yellow is on sale that’s what I get! I have used more expensive like $50-$60 per roll as well and it’s often a pain and super picky for some reason, so I use the cheap stuff. I typically print ABS and PLA (I even got a nice kilo roll of glow in the dark PLA for $9.99, haha, I literally switched my machines parts to work with 3mm filament just because it was such a great sale, haha! Locally it’s also like $12 for a roll of any size and nearly any color (it’s the clearance rack, but they usually have like 10 rolls of a good variety), otherwise retail store mark up your looking at $17 per kilo but they have a whole rainbow gambit of colors and materials (some specialty like carbon fiber reinforced, wood or metal additive, or TPU will cost more). NEMA 17 motor is like $8-$10, so not a lot and the NEMA stepper does not make a good generator so I’d pick something else personally, but that’s roughly what it cost is like maybe $20 in total with the voltage controller and stuff (could be as high as $30).

I have a large (~2-3kw) BLDC motor just... lying on a shelf in my garage. I bet the parts for that 3D printed turbine would scale right up.

The DIY looks like the more fun option. It would also be customisable, in that you could use a better motor as your generator.

Hey bro i like u r way of calculations n 3d printing n all

Excellent video my friend keep up the Great Work! You also need your own tv show on the discovery channel! Your videos are so educational and will help influence kids to think outside the box.

I think there is a disc generator (Scheibenläufer) used in the commercial unit. The problem with the stepper motor is the cogging torque of the individual steps. This force is also higher with the used gearing. I recently printed a vertical wind turbine and made such experience. On the other hand you need some kind of MPPT for a wind generator. Or just make multiple load cases. A single point of measurement is not significant for comparism between both units.

Man, you're really doing GREAT things! Thank you and compliments! In my opinion DIY wins because of more flexible and customizing system. It's a scalable turbine and I'd the pitch it's working, the efficiency should be higher, am I right? Again, thank you!

Well made video and good conclusion :D

Fantastic video👍 Thanks for sharing👍😀

Nice build!

This is such a good video idea

The assembly did not go as planned because it was "Assy". :) Love the videos!

The variable pitch is really important to it's start up and running, go back to it at some point and give it another go, maybe sort a better generator for the printed one? Great video keep them coming 👍

I love your videos. Love long live Germany.

I was looking at printing the 50 watt turbine but ultimately abandoned it as no one seems to have actually got anything useful out of it, making another video for you :) Great video as usual.

Worth to give a try to the Liam F1 Design!

Finaly a true video...thanks..richtig

Very nice video. thanks. I intend to do a much smaller one but i'm not sure if it even charge a single battery.

I'd be interested to know your thoughts on the difference in durability. I assume you used ABS plastic, do you feel like the DIY option will hold up as well as the store bought in high wind conditions? Also, would you be able to customize out the motor for a direct motor? I wouldn't like to use the gears if I can avoid it.

Another great video!

Great video as always, after seeing this I watched a few other 3d printed turbines on youtube. And it looks to me you forgot the spring in the nose cone that pushes on the swashplate. The tention of the spring dictates the force needed to rotate the blades (not the turbine).

With proper design DIY is the winner.

Great video! It would be great to have a few of these if you lived on the coast along with a solar grid. Someday... someday.

The efficiency was highly reduced by the forward voltage of the Diodes. It was not mentioned if they are shockey ones or not. But lets assume 1.2v for two Diodes. In the buy option an output voltage of around 1.5v can be seen. In this case the loss is a bit less than 50%. At the div option a voltage of about 0.75v can be seen, witch results in about 60% loss.

Very clear. Thank you
