Some are asking why this isn't more widely used. Answer: Nitinol has a cycle-life of about 1million, so even with constant refresh of cold and hot, the Nitinol will internally "wear-out" within several days of constant use.
The mixing of the hot and cold causes a reduction in the thermal differential. This is the main reason the ice is melting so fast, and why is slows down so soon. It is very important.
Errol Husaberg I fully understand that the mixing isn't the driving principle of a heat engine, it would just make for a good visual since the engine so profusely mixes the hot/cold reservoirs. It's just a visual way to track how much work is being done by the nitinol and how soon the liquid needs to be replaced.
maybe coating the spring in some water repellant would prevent the water from grabbing onto the spring, so the two liquids wouldn't mix as fast, making the runtime last longer? or maybe adding a drop of soap to destroy the surface tension?
dmk also add several setups on two tanks and then add a small dynamo to produce a working prototype.. and then trial it using an electrical hot water service and a dynamo.. and a cold tank.. then have the dynamo charge battery banks and say goodbye to the power company.
I find the spring a non optimal source for the technical memory property being translated accurately. However, The pin of a gear shaft can have a geometric locking pattern that twisted the integral gear, with a small oriface for the water to move in, (account for surface tension so it can enter.) Describing the pin of the gear that we want mechanical energy to translate the gear for an output of that energy with minimal loss to the gear set between the exchange and movement of water between sides. The gear pin, would be twisted on one side going through tho the other side which would be housed in the warm water section. A tighter twist. As the gear changes in the water, The intermediate twist opens and orifacei which warm water enters forcing the gear to turn back, With each turn and interlocking geometry it would slowly turn the gear. However, to explain the geometry, more a mechanical pencil or pen wit ha push button top. If you examine them, you will see how interlocking geometry's are really helpful. Click once, it goes down and locked because it gets trapped in a place where it can't get back because of the one way shape. you push again it gets back because it goes to the top bypassing the interlocking part. Click, click. I hope that explains what I am stating. So a hollow pin, that as the other turns and clicks into place, it opens a challen to its hollow inside, the warm water rushes in, and spins it back. Clicks again. its closed. The cold water turns it again. ORificae opens... I think it would be slow... and the water in the oriface and hollow pin would need to escape easily, so when the other click open it then goes ota natural position of closed for the warm water to eh other side, but opens a valve like mid t, that drains the water that entered. This would accurate the process. Further more, then the mechancial energy owed have to then be able to have enough stored energy to pump the solution back into the warm area and heat it up also. Whilst the other side is cold. But moderating the properties of escat temrepratures needed. Room temperature. Also the size, ration and thrust of its memory are important. IT would be an interesting relation. to attempt optimize its potential energy. Most of that energy is stored in the actual metal. IT does have a half life, but not sure on the time.. It's a thought, been following this product for awhile.... Applications that I could see useful, are in cars that have variable environmental controls, with wire heating of windows, one could use the metal to alter the contours of the cars for optimized weather, or other useful things, or for winter ponds, verse summer ponds, a way in which the seasons auto mate a process of control, by utilizing the sun, and cold of the climate changes. As for a engine design, it could be an interesting pneumatic, or combination with copper plates and magnets, as a when the copper gets to hot, it could serve as a auto shut off. There are many interesting uses... .
Thanks, good presentation. I got some Nitinol wire, but not sure how best to join it. Can't seem to find any Flux 400 anywhere, or it's not commercially available. How did you join your Nitinol wires? You find it better straight or coiled like you have it?
I would think there would be a real world applications here, say in geothermal in climates where it's cold. Iceland comes to mind. Great video! Thanks.
3.6 K views. Latheman's crazy machines promised to have a bourbon for each view. This machine could have saved the whole world, but the inventor spent the rest of his life inebriated and no more progress was ever made.🤪 Great video. Thanks for sharing.
Thanks for the demonstration. It's a neat scientific 'toy'. It's also quite good at extracting water from the reservoirs at the same time as it moves the heat from one to the other! Odd that it starts by removing cold water, and ends with removing warm water. I wonder why? Shall have to look out for one of them, and improve it with a tray to stop the water from making a mess. The green 'white balance' adds a certain je ne sais quois to the video. ;-p
Does the gear ratio mean this works with a lot of slip between the spring and the wheels? Since of course the spring can't travel at two speeds at once. If that's the case I imagine the gear ratio needs to be nearly even, with just a slight advantage.
Very good! I'm thinking nanoscale applications along the lines of single-celled flagella, rotating discs in a transmission system, etc. Magnetic dynamism could be integrated into the system using Praseodymium.
I bought one but can't get it to run, the wheels look a little chewed up and I think the plastic gears are slipping. Did I just get ripped off or is that the condition of yours as well?
I cannot imagine that nitinol could shrink and expand sooo fast in cold and warm water, I also don’t understand how that little motor keeps spinning no matter how am look at it, but it is pretty interesting stuff.
Would this work as a solar engine? In a horizontal configuration; having the sun heat up the spring on the top side of a divider, and cooling the spring in the shade below that divider...
Ok looks trippy and I like it BUT how will it fair if you were to put a dynamo of whatever size off one of the shafts? Would the resistance kill it making it more of a gimick? It's not very good in the fact you need energy to heat and/or cool water but what sort of power could something like this actually generate?
question, would you say it is sort of related to the steam engine? have you done tests on the effectiveness of your device? Things are only rediculous if we cannot find a practical application for them.
I saw an article on something like this back in the 60's. Using salt to make the drive-band expand. Israel showed a concept drawing of a huge wheel using the Dead Sea for the salt side.
Hello, I just recently learned about nitinol and was absolutely blown away by it's almost magical properties, and I was wondering if you'd be able to share with me some details about the machine, transition temperatures, or if you even had plans of some sort available and were willing to share. I understand it's a big ask and I'm just glad to see such a fascinating contraption. Amazing work!
The original research, at least as pertains to energy generation, was abandoned in the 70’s, so I don’t know if their stats are still available. It looked promising back then, but who knows what problems arose which made them give up on it. The little machine in this video is the best I’ve seen so far. It seemed to have some power compared to the other attempts.
Interesting. How long will the spring last before some kind of fatigue sets in? Any estimate of thermal efficiency? Will it scale up to a useful power output?
we might not be able to use these for large industrial scales. but these devices are still important. they can be used in cases where resources are limited. Say for instance in the wild or we stranded some where at which we could use nature. eg: get natural ice, get water from hot spring and build one to do whatever you need and can use it for. For the sterling engine; we could use it in times of no electricity. Just build a small one that connects to a small generator, light a candle to get it running and charge your phone or radio.
The idea of generating mechanical power directly from heat seems like it could be more efficient than the general format of internal combustion engines. You'd need to refine the mechanism far more than this simple, crude demonstration, of course. But if we invested as much thought and research in this technology as we've already invested in internal combustion, we would probably have a much more advanced result.
Dorpz YTP I was thinking in terms of an alternative form of fossil fuel engine. So you'd get the heat from burning fuel. And the cold could be maintained by a radiator. It would still require fuel, like current gasoline / diesel engines, but I think it might be more efficient (so you get more energy out of the same amount of fuel). But admittedly, this is just a guess on my part. My thought was that there is so much wasted energy (heat, noise, etc.) in an internal combustion engine, and if there was a way to translate heat from combustion directly into mechanical work, it would be far more efficient. Whether this is true or not, I don't know. You'd need to ask an engineer that specializes in this area.
Couldn't it be associated with classic engines ? Engine produce heat and this Nitiol engine need two temperature liquid to function : water cooling system could become energy sources ?
Trials have been made with these and the best output they could get was 16% of the power going in, also the metal fatigues quickly so it needs constant replacements. You are better off with high precision Sterling engines. Still a very neat process that could have it's use in smaller applications.
MsSomeonenew I didn't realize the metal fatigued. (It makes sense that it would, but this is pretty weird metal, so I thought maybe it was exceptional in that respect as well.) That would pretty much kill the idea right there. I'm surprised at the low efficiency though. I mean, where else could the energy be going, for it to be wasted? I can't see how vibration, friction, or heat could be accounting for over 80% of the energy input. (Eventually, my curiosity about this will bug me enough that I'll have to either do some proper research or perform my own experiments!)
what if we use a powerfull magnet motor wich could power up a heater and a cooler in order to keep 1 side of the water warm ,while keeping the other side of the water cold, this way the nitinol motor could spin indefinitly, And since a magnet supposedly should run indefinitly, we could speak here about a perpetual motion machine😊
Does is works in reverse? I mean attaching a motor to the pulleys and make one glass of water heat up while the other cools down, like with an AC unit.
No. It's not like cranking a household fan motor to make it a generator for a light bulb, (which works,) but more like trying to make that one motor power your entire neighborhood. No matter how fast you make the little generator spin, it will break long before you could put a dent in any of your neighbors' utility bills. The heat and lack of heat in the two glasses are massive power sources, compared to the molecular reaction in that tiny spring. Unfortunately due to surface tension, the engine is also self-sabotaging by pulling cold water into the hot glass and hot into the cold glass, along with its own temperature differential. That effect does, however, increase the speed at which the two sides normalize to ambient temp. If your goal is spending fuel to get room temp water, this is the machine you're looking for. :D
Would the belt run in the same direction if the upper wheel had the smaller cog? I still dont get, why it does not block, as the belt "pulls" on both sides inside the warm water. If it is about torque, the big cog should "win", imho...
Where can I buy the pulley system from?... Do you sell it?... or can you please give details on how to make it?... Thank you, love this video. I want to have fun and teach kids.
The last one of those I saw used loops on bicycle spoke like wheel. The loops would expand in the hot water and slide a roller on the spoke to push against a central cam which would spin the assembly. The loops would then move into cold water tank contract then repeat.
Do you think would there be force enough for wire to go through some squeezing rollers to take out most of the liquid transport with wire? Or maybe high surface tension treatment for the wire ("a lotus plant surface effect") to make less mess? Warm beer and cold beer? - way to equalise all beer temperatures? Application could be a cocktail mixer wonder to keep your glass full and cold enough all the time - with moustache a careful drinking while spinning is needed though :) For the video a tea might do visually instead of Bourbon - maybe things are not turning green so fast with a cup of tea? Well done - Thanks for sharing.
So, you have to expend energy to heat the water, and energy to create ice to cool the water. is the energy potention of the geared engine enough to be a net positive energy return? Solar stills could be used to provide the hot water for that side of the engine, but is there a zero-energy way to chill water to a low enough temperature to make this engine work? some sort of peltier, perhaps, or other low/zero cost chilling mechanism?
I'm building a gimmick that is basically a Terminator T1000 from the T2 film using gallium...and I thought this metal also has interesting properties...can you help me brainstorm ideas on what to do with it?
The question is: Does it produce more energy than it takes to a) keep the water in container A cold; and b) keep the water in container B hot? Also, does it work better in some liquids, than others?
1. no its like 10% efficiency if it produced more than it takes to keep the temperatures correct it would be infinite energy and thats impossible 2. possibly
hey have you though of using it as a heat exchanger instead of an engine? pretty much does the same as a vapour chamber just without gases and also you can define the path the wire travels. The only problem is the water sticking to it and falling into the warm water glass. maybe a comparison between this and a plain 6mm solid copper tube in a U shape could show some interesting data.
Amazing, hook it up to a DC motor and you have a little generator! If you live in Alaska you always have Warmth (your house) and cold (outside) maybe something like this can be used over there for power. ALSO, can you provide website from where you got this. I searched for "smart wires' and I got to some American website about power cables.
The problem is it will always be bringing the warmth out and the cold in. The power needed to maintain the temp differential would be more than the generator would produce...
Kenny Downs Have one side of the generator being close to a fireplace, the other side in the snow (on the other side of the wall). You'll be keeping the fire going and getting free power. By the way Nitinol engines produce more power than they consume, it is actually one example of the laws of conservation of energy being reversed (one of many examples). Yep, the conservation of energy laws are completely bogus. They apply to some things, but not all things. Devices that operate over 100% efficiency will actually run cold, they will absorb heat from the environment and turn it into electricity (this reverses entropy of the universe). My statements are controversial, but take them with a grain of salt.
+Naoki Kashima You aren't getting free power. The power comes from heating the wire. Just because it's power that wouldn't have otherwise been used doesn't mean it's free. A much more efficient way to make energy would be to simply turn the snow into steam using the fire and run a turbine off the steam. I'm pretty sure you'd experience a lot less mechanical loss.
Kenny Downs If you want to know more about over unity devices check out: John Searl Generator, Testatika Genrator, Hendershot Generator (this one uses static power), Bitoroid transformer, Edwin Gray Motor.... the list goes on an on. We're living in an era where certain technology never reaches the light of day (because it will upset the current economic structure).
I's it the gear reduction which dictates the drive direction? I guess the problem is if you live in a warm climate it will cost energy to create ice or other cold source in the first place and if in a location with an abundance of ice then again it cost energy to have a heat source?
That burner would have been perfect for keeping the cup on the right hot. Cuz the cold cup although super close would be relatively unaffected, as opposed to a conventional burner stove. Missed opportunity
It's s good demonstration of real life application of SMA. But the problem is you need to heat/cool water & that takes lot of energy. So this engine can't be called a free energy generator.
This is similar to Sterling engine in that it is a heat difference engine. I could see something like that possibly used for pumping ground water in a hot climate. The sun and hot air could heat it up while cool ground water cools it down. Or anything similar with solar heat and large body of water.
Differences between hot and cold and space are really huge so maybe it would be vary good for powering space craft for a few years before fatigue stress starts to set in the metal.
Great experiment! Figure out a way so the nitinol wire does not need to touch the water and your engine will work great! Perhaps using a similar idea to how a nuclear reactor cools down with out contaminating its water. Try using a induction method. great job!
So the water is like a battery. The energy it takes to make the ice and the energy it takes to make the hot water might equal 1500watts and the engine might produce only 0.5-1watts if attached to a small generator...
There's an easier way: Dig down in the right place near those and you can get a steady source of superheated water. It's too mineral-laden to use directly, but you just have to run it through a heat exchanger and you get good old steam suitable for running a turbine. That process scales up a lot better than a nitinol engine and is more efficient.
Geothermal energy is already an established technology - it's just more practical to use conventional steam turbines. Theres two hundred years of investment in making steam turbines as efficient as they can be.
funnily enough it work similarly to warp drive, by contracting and stretching the "spring" either side of the wheels, in either glass causing it to move, contraction and expansion,
Nitinol motors have been around for a long time- the first time I read about them was in 1980 or so. A big reason why these types of devicesaren't more common is that they are very expensive for the amount of power that is recovered. These kind of heat recovery devices might seem like perpetual motion machines or something similar that appears to break some physical law, but they do not. It takes a temperature difference to make power (just like steam engines do), and these nitinol motors are no different- what is different is thatthey operate at very low temperature differences- something like 150 degrees, something no steam engine can do- I know they have been investigated for potentially making steam plants operate more efficiently, as in take the waste heat that is being thrown away and make some more power with it, but I'm sure that the benefits vs cost didn't work out. At one time I played with this stuff and tried to rough out how much it would cost per horsepower.... it was something like 25 to 50 dollars per hp, which is ridiculously expensive, even if the "fuel" (waste heat) is free.

You should dye the hot and cold liquids so you can track how fast they mix visually.

So how does this compare in efficiency to say a stirling engine?

It's very inefficient. The heating of the water takes a lot of energy and a lot is lost. Ice also takes a lot of energy to make.

what if we use a powerfull magnet motor wich could power up a heater and a cooler in order to keep 1 side of the water warm ,while keeping the other side of the water cold, this way the nitinol motor could spin indefinitly,
And since a magnet supposedly should run indefinitly, we could speak here about a perpetual motion machine😊
can that technology be used to make volcano power plant?
how much is the conversion efficiency?
Does is works in reverse?
I mean attaching a motor to the pulleys and make one glass of water heat up while the other cools down, like with an AC unit.
No. It's not like cranking a household fan motor to make it a generator for a light bulb, (which works,) but more like trying to make that one motor power your entire neighborhood. No matter how fast you make the little generator spin, it will break long before you could put a dent in any of your neighbors' utility bills.
The heat and lack of heat in the two glasses are massive power sources, compared to the molecular reaction in that tiny spring. Unfortunately due to surface tension, the engine is also self-sabotaging by pulling cold water into the hot glass and hot into the cold glass, along with its own temperature differential.
That effect does, however, increase the speed at which the two sides normalize to ambient temp. If your goal is spending fuel to get room temp water, this is the machine you're looking for. :D
Would the belt run in the same direction if the upper wheel had the smaller cog?
I still dont get, why it does not block, as the belt "pulls" on both sides inside the warm water.
If it is about torque, the big cog should "win", imho...
Where can I buy the pulley system from?... Do you sell it?... or can you please give details on how to make it?... Thank you, love this video. I want to have fun and teach kids.

hmm with some freon and room tempurature air, would this work more efficiently? (with some way to keep the freon of course)
The last one of those I saw used loops on bicycle spoke like wheel. The loops would expand in the hot water and slide a roller on the spoke to push against a central cam which would spin the assembly. The loops would then move into cold water tank contract then repeat.
Do you think would there be force enough for wire to go through some squeezing rollers to take out most of the liquid transport with wire? Or maybe high surface tension treatment for the wire ("a lotus plant surface effect") to make less mess?
Warm beer and cold beer? - way to equalise all beer temperatures?
Application could be a cocktail mixer wonder to keep your glass full and cold enough all the time - with moustache a careful drinking while spinning is needed though :)
For the video a tea might do visually instead of Bourbon - maybe things are not turning green so fast with a cup of tea?
Well done - Thanks for sharing.
he could just coat it in a hydrophobic coating.
+attack125 you mean something like his own semen ?
does the spring always move the hot water to the cold water or can it transfer the cold to the hot water?
Wouldn't it be doing both? One side of the spring is moving from hot to cold, the other the other.
Is there any way this could be operated with the heat from sunlight? Maybe to power a fan?
Do you have the schematic for that pulley contraption? Can you shave it please
using solar heated water for hot input next?
So, you have to expend energy to heat the water, and energy to create ice to cool the water. is the energy potention of the geared engine enough to be a net positive energy return?
Solar stills could be used to provide the hot water for that side of the engine, but is there a zero-energy way to chill water to a low enough temperature to make this engine work? some sort of peltier, perhaps, or other low/zero cost chilling mechanism?
there will NEVER be a positive net return. free energy does not exist.
Well there are different grades of nitinol, typically they will revert at temperatures of 60-115 F.
I'm building a gimmick that is basically a Terminator T1000 from the T2 film using gallium...and I thought this metal also has interesting properties...can you help me brainstorm ideas on what to do with it?
I know this is a 5 year old video but how did you join the two ends of the spring?
I thought it only contracts when heated, why does it expand when its getting cold?
The question is: Does it produce more energy than it takes to a) keep the water in container A cold; and b) keep the water in container B hot? Also, does it work better in some liquids, than others?
1. no its like 10% efficiency if it produced more than it takes to keep the temperatures correct it would be infinite energy and thats impossible 2. possibly
How much power it can deliver for the unit temperature difference...??
I wonder if you could use nitinol to improve the efficacy of a stirring engine. Not you, specifically, but someone.
Would make a great science toy! Also, would be an interesting way to build a pump!
hey have you though of using it as a heat exchanger instead of an engine? pretty much does the same as a vapour chamber just without gases and also you can define the path the wire travels. The only problem is the water sticking to it and falling into the warm water glass. maybe a comparison between this and a plain 6mm solid copper tube in a U shape could show some interesting data.
imagine an airconditioning unit that almost powers itself based on the temp difference from inside and outside..
Yes, then think some minutes more and forget about it.
I see you use a spring but how do you connect the two ends. the ones I can order are strat.
wonder what the possibilities for using nitinol technologies in the home to recycle energy used in a fridge freezer or your heating.
Nice job! where did you even find a loop wire like that?
I have a way to optimize the use of this metal in an engine that could power a vehicle interested in hearing about it?
A hot air and a fan for the coolmside works also. Just need the spacing to be set up different. Air is less messy
Any idea how much load it can handle?
Can we use this nitinol with peltier? It is complete engine..
Amazing, hook it up to a DC motor and you have a little generator! If you live in Alaska you always have Warmth (your house) and cold (outside) maybe something like this can be used over there for power. ALSO, can you provide website from where you got this. I searched for "smart wires' and I got to some American website about power cables.
The problem is it will always be bringing the warmth out and the cold in. The power needed to maintain the temp differential would be more than the generator would produce...
Kenny Downs Have one side of the generator being close to a fireplace, the other side in the snow (on the other side of the wall). You'll be keeping the fire going and getting free power. By the way Nitinol engines produce more power than they consume, it is actually one example of the laws of conservation of energy being reversed (one of many examples). Yep, the conservation of energy laws are completely bogus. They apply to some things, but not all things. Devices that operate over 100% efficiency will actually run cold, they will absorb heat from the environment and turn it into electricity (this reverses entropy of the universe). My statements are controversial, but take them with a grain of salt.
+Naoki Kashima I will definitely take them with a grain of salt.
+Naoki Kashima You aren't getting free power. The power comes from heating the wire. Just because it's power that wouldn't have otherwise been used doesn't mean it's free. A much more efficient way to make energy would be to simply turn the snow into steam using the fire and run a turbine off the steam. I'm pretty sure you'd experience a lot less mechanical loss.
Kenny Downs If you want to know more about over unity devices check out: John Searl Generator, Testatika Genrator, Hendershot Generator (this one uses static power), Bitoroid transformer, Edwin Gray Motor.... the list goes on an on. We're living in an era where certain technology never reaches the light of day (because it will upset the current economic structure).
I's it the gear reduction which dictates the drive direction? I guess the problem is if you live in a warm climate it will cost energy to create ice or other cold source in the first place and if in a location with an abundance of ice then again it cost energy to have a heat source?
Potentially you could control speed by the tightness of the spring then?
That burner would have been perfect for keeping the cup on the right hot. Cuz the cold cup although super close would be relatively unaffected, as opposed to a conventional burner stove. Missed opportunity
What about electricity, can expand and decompress with electricity?
Can this run 240sx for drifting pls?
How do you make a spring out of that material.
Unbelievably cool!
It's s good demonstration of real life application of SMA. But the problem is you need to heat/cool water & that takes lot of energy. So this engine can't be called a free energy generator.
Lets supuse we use it in cars, how would you keep it warm and cold?
Very clever device! ! Nitinol was discovered by the US Navy in WW2
GREAT! May I ask how did you bring it into spring shape and how did you connect to a spring loop? Thanks in advance from Taiwan.
He probably bought it but you could also just wind it yourself. You have heat the material up to something like 500F for it to keep it's shape.
How can i contact the publisher to as about this am doin it as a project for college thanks for help
Electic power generator for home use would ground breaking. or when can you build one
So what makes beer and coffee a nuclear waste I used to mix seagram's and coffee. So what makes that combination a waste for real
if this could work in extremely hot air as apposed to liquid, it could be applied to anywhere that had a hot exhaust pipe.
And turn a common byproduct into a very short lasting shitty power soirce, likely made at a loss
Cool stuff here. Mind trying it with a thermal camera if you can get a hold of one?
Legal Planet or he can dye the waters different colors so more people can see it, seeing it is cheaper than a thermal camera
Is there a crystal lattice structure within the metal?
This is similar to Sterling engine in that it is a heat difference engine.
I could see something like that possibly used for pumping ground water in a hot climate. The sun and hot air could heat it up while cool ground water cools it down. Or anything similar with solar heat and large body of water.
Differences between hot and cold and space are really huge so maybe it would be vary good for powering space craft for a few years before fatigue stress starts to set in the metal.
How dare you even THINK of hot coffee mixed with cold beer ? Way cool engine, take a point.
wonder if this could be used as supplemental motor for a small boat, an outboard heats the water and the outside water is cold Hmmm! nice vid thanks
A plastic tray under the two glasses of water ..
Great experiment! Figure out a way so the nitinol wire does not need to touch the water and your engine will work great! Perhaps using a similar idea to how a nuclear reactor cools down with out contaminating its water. Try using a induction method. great job!
From 1:00 to 1:29 you show how you can turn the pulleys back and forth, can you please show that over and over again, I didn't see enough of that!!!!
So the water is like a battery. The energy it takes to make the ice and the energy it takes to make the hot water might equal 1500watts and the engine might produce only 0.5-1watts if attached to a small generator...
How much is the efficiency of it? 10%?
Probably closer to 0.10% , but I don't really know.
The efficiency is above 10%, that much I know for sure, but less than 50%.
Not at all… probably 0.0000004 something
mehhh idk probably around like 110% or something
great video interesting properties inspiring me more in the search of perpetual motion
I wish you the best of luck but I think you will be at it a long time. I appreciate anybody who searches for ultimate efficiency though.
nice goal. will keep you busy untill you die. all goals should be life long.
yeah I agree until I read somewhere laws of thermodynamics only dealt with the infra red spectrum of energy..
fidel catsro
where? donald duck?
@@fidelcatsro6948 what
Hahahahaha
Could be uses to harness energy of geezers and glaciers in Iceland! Any technical reports or thermodynamic studies?
There's an easier way: Dig down in the right place near those and you can get a steady source of superheated water. It's too mineral-laden to use directly, but you just have to run it through a heat exchanger and you get good old steam suitable for running a turbine. That process scales up a lot better than a nitinol engine and is more efficient.
+Vyl Bird Thanks for the insight.
Geothermal energy is already an established technology - it's just more practical to use conventional steam turbines. Theres two hundred years of investment in making steam turbines as efficient as they can be.
I don't get how it creates the movement. How does that contracting spring cause the whole thing to rotate?
funnily enough it work similarly to warp drive, by contracting and stretching the "spring" either side of the wheels, in either glass causing it to move, contraction and expansion,
it doesn't. prettuy sure it's fake. even looks like he flips a switch when he "pushes down" the ice
yeah i was being very sarcastic :-)
Nitinol motors have been around for a long time- the first time I read about them was in 1980 or so. A big reason why these types of devicesaren't more common is that they are very expensive for the amount of power that is recovered. These kind of heat recovery devices might seem like perpetual motion machines or something similar that appears to break some physical law, but they do not. It takes a temperature difference to make power (just like steam engines do), and these nitinol motors are no different- what is different is thatthey operate at very low temperature differences- something like 150 degrees, something no steam engine can do- I know they have been investigated for potentially making steam plants operate more efficiently, as in take the waste heat that is being thrown away and make some more power with it, but I'm sure that the benefits vs cost didn't work out. At one time I played with this stuff and tried to rough out how much it would cost per horsepower.... it was something like 25 to 50 dollars per hp, which is ridiculously expensive, even if the "fuel" (waste heat) is free.
I presume that comment wasn't directed at me?
