I will be waiting for your that vedio 👍👍

i never knew his name was James 😀

Ok now I know his name thx

Wait 4:20 is this perpendicular motion

@@maniacmemes5746 you don't knew his name? His one clip was shown on TV there hosts tell his name

I have seen it tho often

@Unsesquipedalian oh yea i have a nickel titanium wire in my bottom row of braces

Body panels of a car lol be putting auto body shops out of business

rice cookers. when all the water is absorbed, theres nothing to stop the temperature from rising, and as soon as it gets above boiling temp a shape metal alloy triggers a switch that stops the heat. ive also heard of them being used in a similar way in shower heads as a safety measure that block the water if it gets too hot.

There are magic props designed using this.

Yes

I want to see how many watts it could produce if connected to a small generator. It would be pretty amazing if this could charge a battery

So.... Caterpillar Drive?

it wouldn't make any power. It barely spins itself. Apply load and it will stall

@@dieselgeezer18 You could make it as powerful as you want by increasing the width of the band.

Hmmmm idk

I used nitinol wire probably thousands of times and never had any problems until I accidentally overheated the wire in one spot. After that it had problems getting back into position.

Good question with a weird/fun answer, not only does does nitinol not fatigue like other alloys it actually GETS STRONGER over time kzfaq.info/get/bejne/bpOUdqycr6fOqYE.html and this lab tested it to 23 million cycles kzfaq.info/get/bejne/pbGdjNSGuKrHmGw.html I looked into this material a few years ago. Most of the documentaries are from the 70s but well worth a watch and it seems that the applications for this material are numerous with my favorites being self expanding stents (triggered by body heat) to repair collapsed arteries and self reforming tires on the mars rover intended for use in an environment where regular rubber tires would shatter like glass.

Yes like all metals it undergoes fatigue, nitinol engine can last between 10^4 to 10^7-8 cycles depending on the strain (lower strain= longer cycle duration).

@@aetius31 that seems crazy..strong enough for light weight high efficiency heat combustion engine…

That is exactly what I wanted to hear, thank you

Yeah, you can have a ton of fun, implanting devices into people. That doesn't sound suspect at all.

@@Mecharnie_Dobbs Yeah, especially when you are saving the lives of those people

💡that might work

Heat pumps do a similar thing using liquid gas instead of Nitinol

You mean like lifting a cup of rocks? 🤔

​@@willyjimmy8881 i had a feeling a numb nuts would come along and request clarification. No, i do not mean weight, I mean electrical load.

@@h7opolo The numb nuts is the one who clearly says non-electric THEN requests an electric load application. Anyhow, read about OTEC, not Nitinol, but applies the hot and cold theory in large scale applications.

@@h7opolo please do not ridicule someone who is asking questions!! People like you are the reason why children grow up with a fearful aptitude. When I was a kid my parents used to clear my doubts gently but not so much in the school, so after a point of time many students stopped asking questions. I don't know how it is affecting them now but surely it does affect people. 😕

@@willyjimmy8881 Rocks, number one component of all starship bridge consoles.

Excellent question...I want to know the same...

Hmm.

I was wondering the same thing.

I've heard it can bend an infinite number of times (if it's pure) but can't say for certain.

Yes, just like all metals. It's more of a question of how much it takes.

Agreed, this would be so cool!

I dont think that air really heats it up fast enough for it to properly work. warm water with cold air would be better, but also less common in reality unfortunately. cant scientifically back it up for now, but definitely feels that way

@@allylilith5605 you could keep some room-temperature water in the boat and have the wire wrapped around the wheels in a figure 8 formation, so that the narrow point of the "8" is above both bodies of water. Wrap some toweling arround the wire at certain points, to stop it from carrying drops of cold water into the room-temperature water. If it was full-sized, then you could sit in the room-temperature water to stop it from cooling down. Or you could have the tiny buckets attached to the room-temperature wheel, to catch bits of room-temperature air and force them to bubble through the water in the boat, to maybe stop it from cooling down? No, put something black over the water in the boat, so it will absorb sunlight and so stay warmer than the water the boat floats in.

What's the name of this metal?

@@jayantpramanik9569 Nitinol

He copied this from other channels.

Thanks, Sharuk! We're glad you found our service useful 💪

And vsauce too!

TRUEEEE

Yeah 😃😃

@@weakboy6871 some days ago, I tried to saw the very first video of vsauce and I just came back by seeing the thumbnail... Thinking how that channel transformed into an educational channel!

OK YOU DONT HAVE TO FUCKING YELL

Oh wow, it's pretty old

@NotRickroll👇 bro youre better than that

As in change the shape it remembers? Yes

Isn’t that what he’s showing at 3:17?

This is like a flipflop logic when reset is high

@@marsrocket no they mean if it gets hot enough you can shape it to remember whatever you want as it’s regular shape

general electric actually did a feasibility study on nitinol robotic actuator back in the 80s. Unfortunately its energy efficiency is extremely low about 16% base on experimental data, compare to electric motor of 95% and internal combustion energy of 30%, and even lower than pezoelectric motor of around 25%. And another issue is once you get to full scale actuator, it's very difficult to get the heat out to reset nitinol wire, so its cooling energy need for the equivalent power is much higher compare to other similar type of engine. Nitinol actuator does have pretty small packaging though, so in situation where power efficiency is not needed and it's operating in a thermal stable environment, some thing like endoscopic robot. Another setback that nitinol actuator suffers is since heat conduct through actuator material it self, so unless you have a very accurate heating and cooling control, its position precision control is much less when compare to pezoelectric motor that can have micron level precision at a high seek rate. So overtime nitinol actuator lose out to pezoelectric motor on the precision front and lose out to electric motor on energy efficiency front. Its only niche left is that it has very small packaging need, so mostly used in endoscopic robot that go through small pipe or go through human blood vessel to clear out plague.

Omg I found another person who knows that word. I am unable to experiment but I have plenty of experiments to try. I have been studying Soundwaves and Sonic light for about 5 years now. I recommend the video from the thought emporium if you haven't found it yet. He details the basics of the setup and some ways it can fail. We need to try the experiment with larger scale. Also with different materials. Also the bubble created appears to be plasma but has never been studied in any way. I want to know the energy available in said plasma and if somehow it's greater than the energy required to provide the Soundwave we've solved infinite energy.

@@V1ctoria00 I've already watched that one but unfortunately I don't have the equipment nor money to buy it 😒

I believe the way you'd do that is to heat it above the austenitic phase he mentioned in the video. This would cool down in the shape you put it in, form the rigid austenitic bonds, and then further cooling relaxes those bonds into the martensite phase which makes the metal exhibit plastic behavior.

I guess you just have to hold it in place as you heat it up: kzfaq.info/get/bejne/jJ-hqLaqzJ7Tmmg.html

I was thinking the same thing

I think this explains it, from Wikipedia: "Nitinol alloys exhibit two closely related and unique properties: the shape memory effect and superelasticity. Shape memory is the ability of nitinol to undergo deformation at one temperature, stay in its deformed shape when the external force is removed, then recover its original, undeformed shape upon heating above its "transformation temperature". Superelasticity is the ability for the metal to undergo large deformations and immediately return to its undeformed shape upon removal of the external load. Nitinol can deform 10-30 times as much as ordinary metals and return to its original shape. Whether nitinol behaves with the shape memory effect or superelasticity depends on whether it is above the transformation temperature of the specific alloy. Below the transformation temperature it exhibits the shape memory effect, and above that temperature it behaves superelastically."

you just have to heat it up enough, not necessarily melt it

I was thinking the same thing too

Keep up the good work !

yes it must be more than 200 c

Yeah, this channel is fun to watch

Huh?

Nitinol has a memory temperature where it will "remember" the shape it is currently in. This is around 500°C.

Yes

No

Cool

Holy sht i actually were the first one
