When the dam broke it immediately was clear why dams are thicker on the bottom 😅

If you move the turbine back and have the water flow over it instead of under it will generate more power..

I think you're trying a lego version of what is called a Pelton turbine, where you force the fluid to hit a "spoon" on the edge of a radial turbine. This, however, requires a really fast flow (that hits the edge of the blade for max angular moment) and a special design both for the blades and their amount (the flow of water might hit the back of the next blade, lowering power output). I suggest going for the so called Kaplan turbine. Its design will definitely be trickier (I can help), but the fact that it is an axial turbine will let you worry less about the speed of incoming water, but most of all you can still use a flat blade instead of a curved one which is great for Lego. This will undoubtedly improve the performance. Lastly, the output section is really important and it is crucial that you control the flow. Make it a conic shape (with the section increasing downhill): this will slow the flow down and it will maximize the energy that the turbine can absorb)

The sight of that battery box and motor fills me with pain, knowing how much those things cost.

Call me a conspiracy theorist but I don’t think a beaver built this

This is what real muscular and succesful men watch

I always find these videos interesting cause it's taking whats considered a kids toy and making incredible feats of engineering

I think youd have more success with fan-shaped or screw-shaped turbines, rather than those paddle-shaped ones. Idk if there are technical terms for those, but there you go. I also dobt know if there are any lego pieces for screw-shaped turbines, but im pretty sure any boat propeller piece would work for the fan-shaped one.

the restraint on this guy not to say anything when the dam broke is insane

Really cool to see how you managed to get this working!

Just as I thought this channel couldn't get any cooler...

I think a simple gearbox would've allowed the turbine to spin easier while still being able to turn the generator

I wonder if someone would 3d print you LEGO Pelton Wheel blades? Pelton Wheels remove nearly 100% of the waters kinetic energy. Also, thanks for including the failures! Seeing the process is half the fun for me - the other half is the projects/challenges - and the third half (roll with me on that) is the LEGO!!!!!

Pretty cool! But when I look at it, if you want to improve it, then I think that you should make the turbine only let water flow through if it turns the turbine. You could do this multiple ways, but I think that would greatly improve the efficiency of this system. Either way, great job! Very interesting to watch, thank you,

a couple more lego dams and you wont have to pay the eletricity bill!

now you need to make one that becomes self sufficient and can run it's own pump lol

Water.))))))

I really like Lego models that include water they're so cool

Really interesting experience good job 👏

Wow ! This is serene and developed. 우와 ! 이것은 고요하고 발전된 것입니다.

I felt that when it broke 😅

I think that you should use a gearbox with a small gear on the turbine and a big gear on the motor, making this will increase the force and reduce the speed but will make the motor spin and create some power you can store. Also you could calculate the efficiency if measure the power taken by the water pump and the output power of the lego generator. Great project, thanks for sharing!

I love your experiments...somehow I feel like you may be my high school science teacher lol

Bro created his own energy source 😂

It would be really cool if the turbine could generate enough power to operate the water pump, thus creating perpetual energy! My guess is that clever use of gravity would be required.

That's really cool! *Now make a lifesize one.*

The last words should have been: "UNLIMITED POWAAAAAA!!!"

Your water videos are the best!

Could you weave a piece of kitchen plastic wrap in between the layers vertically to improve water retention?

A tsunami is coming down the river in Lego City!

6:40 just change the ratio of the bevel gears and it will work you are making this much harder for yourself mate

What a Dam good video

Dat is prtty darn cool!

谢谢分享！太开心了😊

I love making water pump videos from lego, so I really like your videos, especially the video have water pump

Do more stuff with water! 😃

Would adding scoops to the turbine blades and pouring the water over the turbine instead of under, increase efficiency?

Cool channel, very entertaining yet educational, I can see not only adults but the youth also be interested in what you upload. Just in case nobody's already mentioned this, from what I've gathered, the motor and generator serve different purposes, if you used a generator it would have less resistance and spin faster, which is ideal for what you're doing. Keep up the nice work!

Love lego

This is incredibly cool.

A proper penstock (from top of water level, to very bottom of tank) would help with water pressure. Also having water exit turbine at only 90* contact area is wasting basically 270* of the wheel surface area (why real ones have a completely circular scroll case.) This scale makes a good turbine design more difficult, but I’m sure it’s possible!

You can tell that he experience true pain when it first collapsed

Amazing idea definitely gonna subscribe to see further content furthermore how much power you think you can generate?

just imagine howmuch preassure is on a normal dam.

Try an over run feed to the turbine. That way the weight of water will be pushing down on the blades

Love seeing the progress and the interactions with water. Are the lego motors water proof?

me when i saw how tall the wall was: "Daaaaaanm!"

"yo you got an phone charger?" "here"

aiiiii that first test

We now know how the three gorge dams going to go

3:37 The fact, that powered up hub fell into the water, scares me, and I see that the light on the hub fades.

By letting the water flow over the turbine instead of under, you can use the weight of the water also for extra power. Like how old timy water wheels work. Now you are missing most of the power generated by the water that passes by the turbine as it rotates.

DAM! That's a lot of work... And work editing!

So cool!

I think if the turbine had more curve to allow water to travel on it and it entering at better angle would allow it to spin faster rpm with a lot less water

ooh this gonna be cool love your work

Bro learned real quick why dams are not flat walls lol

Because you had the gear ration set as big to small instead of small to big, improves torque on motor/generator

Lego nuclear power plant

LoL fun exersize ... you should calculate the power efficiency ... consider higher reduction gear on the power wheel for turbine

Good job. You converted like 10 watts from the pump to like 0.1 watts or less (;

if you manage to force the water to "fall" directly onto the turbine you could abuse earth's gravity pull to an extent

there is only so much time it will take for someone to make perpetual motion from lego

Wow! Yet another great video. Keep it up! :)

if u use turbine no.2 and make it angled it will work perfectly

Wow This is cool I think I am the only one to nevwr play LEGO!

Return angle are expansive. If you need a idee, you can do seed press or oil press with really seeds

Damn!

You should make an even bigger dam

That was interesting to get to see what happens when a dam is not built properly🤔🤔🤔🤔🤔

hi what are the parts you used for building the turbine? pls tell me asap I wanna do something like this but maybe with wind.

I did too. In 1969 for my 6th Grade science fair in a 10 gallon fish tank. It wasn't nearly as fancy as yours but water did come down a sluice and into a building where it turned a generator that lit a flashlight bulb. I had to have an external power and pump to return water to the reservoir but that was hidden.

I don't know much about lego... Or dams... But this pretty cool

Goooooooooooooooooooooooooooooooooooooooooooooooooooood!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Dude i love it!

Dont know for sure but maybe some cogwheels can help a bit

its a shame this video only has 925 likes in four days

overshot waterwheels are a lot more efficient compared to undershot and stream driven wheels

When your It’s time to generate electricity using a steam turbine, or better yet, build a nuclear power plant

3:39 Dam it! Oh and by the way, maybe you meant "First kill"

❤

Secret: add another turbine it’s so simple!

That's awesome. Your videos a great!

make a oil rig next please any of your water videos are awesome!!

Dude awesome!

my man working at hydro-quebec tabarnak

3:40 LOL 😂

Next time you should try it in a real river😊

Dam, that's cool

Put it more forward to create more pressure

100 commen tthis is a great build keep up the work

Amazing one!

ths is cool/fasinating

It's so cool

Well. Ill be dam.

The pain when I saw his hands 😭

Adorable ^×^

Dam

Over shot the wheel and ad buckets for more power. You've technically got a water wheel not a turbine. Still cool.

3:30 Never watched Lego dam breach experiments before, huh? Also, i noticed you didn't twist the stones while building your dam.
