HUGE Lego Technic Flywheel & Clutch Lifting weights with Stored Energy! 4k 

Thank you for this :)

While flywheel based roller coaster launches do absolutely exist, and were produced by a German company, none exist in Germany. Hydraulic, pneumatic, or magnetic launches are far more common methods used on coasters.

What Ride are you talking about, Fluch von Nowgorod?

@@spaceistheplace2293 in Italy we have a magnetic coaster it’s called highspeed

I can’t imagine the clutch on one of those things

Cheers for doing that again Sam! Appreciate it :)

You can calculate horse power from this really easily. Hp is defined as how fast a device or engine can lift a weight to a specific height. I think the weight is 500 pounds and the length is 10 feet. That’s probably wrong though. But what you’ve built is almost exactly how hp was invented except instead of a flywheel it was a horse. Very cool and you should totally calculate the hp of the different flywheels.

James Watt, a Scottish engineer and designer of an enhanced steam engine in the late 18th century, gets credit for the term horsepower. He measured how much weight a horse could lift over a known distance in a minute and found it to be a little over 32,500 foot-pounds of force. He then rounded up and divided by 60 to get 550 foot-pounds per second. And, voila, horsepower. So I had the equation a little backwards but the idea is the same. Here is the actual equations you might need to calculate this. en.m.wikipedia.org/wiki/Horsepower

@@letsdosomething6691 Yes, if you measure how long it takes to lift the weight by a height then the power is simply m x g x h / t. I would regard this as being a measure of the power transfer capability of the clutch rather than the flywheel (which is technically and energy storage device)

@@GazRsExtremeBrickMachines can you try the top speed gear model using brushless DC Motor?

Thankyou very much! they’re fascinating things, I really wanted to push it more, next time hopefully :)

Theyre good weapons too if you put 2 teeth on each end of them

Actually they can’t hold that much energy. The chemical energy stored in an equal mass of gasoline could do this lifting for hours or even days.

@@Mike-oz4cv I know, the fact that it can even lift the weights is impressive. I wouldn't expect it to get off the ground.

thats why theyre so heavvy

Hey thank you Taylor, honestly I’m pretty new to clutches with Lego and have a bit to learn. There was just too much torque to handle on this one :)

Hey thank you that means a lot :)

no problem just getting those good ideas is the key

Hi

Hello there! I have one idea for you to try- if you could attempt on making Mars rover type of vehicle- 6x6 or maybe 8x8 drive with some insane suspension, and also maybe a claw to lift some stuff and put into some type of a bow on that vehicle. Sounds pretty challenging but i think it would be easy for you!

Box* sorry I missed letter while typing.

@@brickleymotion hey there nice idea! I think they use a rocker type rear axle which work well! I will do something like this thanks! Also a weird 8x8 vehicle :)

Hi there thank you for that nice to read! I’ve seen a few on RU-vid and always found the power fascinating :)

@@GazRsExtremeBrickMachines you could built some lego version of a batteryless UPS with your flywheels to measure the stored energy ;)

Hey thank you for that I’m glad you liked it :)

Hey that’s a great point and idea, it definitely would put them through their paces! :)

@@GazRsExtremeBrickMachines I'd love to see it!!!! You can also test power transfer with it lol

@@GazRsExtremeBrickMachines Looking back now, it seems when the string winds on the shaft it's essentially changing the pulley ratio by changing the diameter of the shaft. So as it lifts it gets harder to lift. Perfect stress test for clutches and flywheels!!!

I’ll pass the compliment on cheers :) Sometimes not as adorable at 5am haha.

@@GazRsExtremeBrickMachines Oh, believe me, I know; I've got one that won't shut up, and I can't figure out what she wants. x.x lol

@@Sean-Ax lol Awe bless! Food food or a different flavour food to the last 7 flavours…. Charlie’s life long friend/sister(Ruby, was in a few videos) died a few weeks back and he’s so clingy at the moment! He still goes around looking for her which is so sad. I now miss her waking me up at silly times :)

Hey thank you :)

Hey thank you very much! Originally I had no clutch but I couldn’t keep tension in the line and things got messy lol. I do have a different way to do it next :)

Hey thank you for that I’m glad you like it :) From another Gaz in 84 :)

Hey Jared thankyou so much that means a lot! Sorry for the late reply 😀

Hey there thank you so much that info and idea, I will look into it cheers :)

Care to elaborate?

@@mister_bomb7777The original energy source for the entire system here is batteries.

😂 I remember I used to watch many moons ago! I might connect my 39 motor setup on this and see at rpm things get interesting lol.

Hey thank you very much! I’ll definitely use more motors next time, it could get interesting… lol :)

Lol he’s quite a big guy as well, 7 KG! Lol

Hey thank you so much! Appreciate the feedback :)

Hey Chris hope you’re well! Cheers :)

Hey there thanks for the suggestion I really do appreciate it! Nice idea :)

Hey great to see you about :) thank you very much!

Hey there interesting idea I like that! I will definitely do things different next time! And thank you very much :)

@@GazRsExtremeBrickMachines something else i thought of, if your clutch continues to slip you can make a "clutch pack". How they normally work is they have disks keyed to the shaft and a "cage" going around the entire pack, alternate one disk for the shaft and one for the cage until the clutch stops slipping.

Hey thank you very much :)

Thank you Felix that means a lot 😀😀

Indeed I hope you’re good! And thank you :)

@@GazRsExtremeBrickMachines 👍😉

Hey there thank you so much for the that i appreciate it! That’s a cool little idea I like it. I do love flywheels too I have a good little test soon and will use one on a Lego saw as well :)

Do you think small ratcheting mechanism could solve that problem?

@@shlushe1050 well... I don't think so, a ratcheting mechanism won't absorb the shock, it'll just hold the elevator up and prevent it from falling, but how will we get the elevator down after that?

@@abossoum2392 that's the point lol, after it goes up it'll hold itself up showing how efficient it is at transferring power. Then to release it you can release the holding lever, ratchet and tooth

Hey Lee thankyou so much that means a lot thanks! I hope things are good, cheers :)

Hey thank you so much :)

Hey there I stayed at a hotel once which stored energy in a flywheel at cheap electric rate and released it at expensive rate :)

@@GazRsExtremeBrickMachines That's really cool! I didn't know local business implemented such technology at all!

@@EnigmaScience I was surprised too!

Hey cheers Carl it’s been too long! Originally I had no clutch but I couldn’t keep tension in the slack line well enough and then it wanted to destroy itself when it hit the top lol. I think the gearing would help but I’m hoping to pull or lift a lot lot more! I know you’ll know so much more about Lego clutches than me, I think this is my first! 😀😀

@@GazRsExtremeBrickMachines oh I get it now. Why not use a differential as torque sensor - when it hits the stops, the torque rises rapidly and the diff operates a cut off switch and disengages drive. Not a million miles away from the auto geabox thst @MaxBrix and others did. I know little of Lego compared to you! 'tis great to see what other people come up with. Now RC cars.... there's some good stuff there and I bet you're just a few moves away from getting into that as well. Take care 👍🍺🇬🇧

I’m still trying to keep away from RC! I love your 4x4 crawler so much! Thanks for the info Carl I really do need to learn a bit more on this! It’s weirdly one thing I never played about with much when I was younger. 😀🍺

Hey thanks Max I’ll look into that! Cheers :)

Interesting point and I will check that out! You could have hit the problem, I’ll take a look cheers :)

Hey Nathan nice to see you around still thank you very much :)

Omg I’m so glad to see you reply :) and thank you very much I hope things are good!

@@GazRsExtremeBrickMachines your welcome! You to man

Thank you so much :)

Hey there cheers thanks for that :)

Hey Easton I searched for your name on replies but it didn’t show! Thankyou very much as always! I’ve been well thankyou, a few around me not so which I think had some effect but I’ll be busy busy from now on :) Great to see you about 😀

Hey there thank you for, interesting :)

Hey thanks Alessio, it’s been so long! Hope you’re good :)

@@GazRsExtremeBrickMachines You too! :)

Oh wow thank you for that cheers :)

The thought scares me lol. But yes every little helps :)

Thank you so much :)

Hey there thank you for that I think I will get rid of the clutch, I’ll play about with things. The big problem is getting things to handle the torque :)

Thank you very much for this comment! Sorry I’ve been away and logged out. I’m continuing with the project shortly :)

Hey hey thank you so much! Hope you’re good :)

Hi Edwards thanks for that I’m glad you like it, was a fun project

Hey there I hope you’re well! It will happen and so glad to see you comment! Cheers :)

@@GazRsExtremeBrickMachines im doing great. all I can say is you are the best!

Haha hey Donnacha! Nice to see you still around thank you! You would need big brakes lol, I think I used two thirds of my panels! There’s a crazy amount in there. Think 300 plus eek

Hey thanks Erik, more work needed on the clutch :)

Hey there it is, so nice to see you around still thank you 😀

I wish you did! Awe thank you, he stayed with me till 7am the next morning whilst I finished filming and editing. :)

Oh nice cheers for that :)

Hey hey I hope you’re well :) so glad to see you around I was worried my channel would disappear from the radar :)

Hi there I’ve read about the buses using huge flywheels, fascinating stuff. The energy is immense!

Oh wow thanks for that info! It’s scary how much energy big heavy flywheels can hold! Although my experiment didn’t show it too well lol :) I know the lmp1 cars a few years ago had flywheels where a passenger seat would usually be and spun up during braking by electric motors and then released the charge back to the front axle at the corner exit.

@@GazRsExtremeBrickMachines oooo, nice that is another cool use of flywheels.

Hey! Thank you very much 😀😀

Hey there that’s a very interesting idea thank you for that! Your English is great too :)

Hey hey! Yes hopefully for a long time 😀

Hey there that’s a great suggestion! Thank you so much, the second flywheel is a great idea!

Hey thanks I’ll pass it on :)

Hey yes nice idea, I needed a double clutch when one engages the other disengages maybe :)

Hey there! Thank you very much appreciate the feedback :)

Thank you very much Peter :)

Hey there great to see you comment! It means a lot after all this time 😀

Hey there thank you for that! A bigger clutch would help hugely! Also my rubber studs have gone a little dry which didn’t help :)

Cheers I’ll pass him the compliment :)

Hey yes they do they’re fascinating things! I stayed at a hotel which spun a flywheel under cheap rate electric and released the energy during high rate! :)

Hey thanks for the idea it’s much appreciated :)

Hey thank you for that! I know it’s been too long :(

I was hoping someone would explain how to work it out :) The energy always surprises me.

@@GazRsExtremeBrickMachines I can help with that! The energy stored in the flywheel is 0.5 x I x w^2, where I is the moment of inertia and w is the rotational speed ( in radians per second (= rpm / 60 x 2π)). The moment of inertia depends on the mass distribution through the flywheel, but for a solid disk is 0.5 x Mass x radius^2. This energy is then transferred to gravitational potential energy, which is calculated as the mass of the load (in kg) multiplied by the gravitational constant (approx. 10m/s/s) multiplied by the vertical ascent (in metres), i.e. energy (in Joules) = m x g x h. In your last case before the clutch gave out the machine lifted 1kg by about 50cm (guess) so that gives 5J of energy output. The efficiency of conversion is simply the ratio of these two energies. P.S. don't be disappointed if the efficiency looks quite poor!

@@sammason2300 that’s great info thank you so much! With a working clutch I have confidence it can do much better haha. I really appreciate the time for that reply cheers Sam :)

@@sammason2300 hey could you copy paste that as a new post if you get chance! I will pin! People like this stuff :)

Hey Aaron I should have done this tbh. I was worried it would lift to slow but it would have been ideal. Cheers :)

Thanks Ian much appreciated :)

Hey there I kind of wanted to try this but the nylon kept binding too much producing a lot of friction which didn’t help. I’m sure with a proper set up you could store quite a lot of energy like that :)

makes sense

Hey thank you very much :)

@@GazRsExtremeBrickMachines 👍

Hey that’s a great idea! The energy stored is something else, the problem is not snapping an axle when converting it! I’m actually filming the supersonic video tonight all being well :)
