The energy use must be obvious to anyone watching this channel. Would be nice to have the exact number though, so we can compute if the energy costs less than what we make in the time it takes to refill/empty a tank in a non-dehydrating robot cleaner.
@cupcake_toucher445 not much water and condensing - not freezing. And if done smart it should not be that much - the heat generated from condensing new water can be used to evaporate the dirty water.
I have a feeling this thing, although well thought out, is so complex, and has so many moving parts, and has subsystems that absolutely have to function correctly, is going to be a maintenance nightmare after about 3 months of use. I hope they've life cycle tested this thing thoroughly.

This stoopid thing costs 1900. Just to avoid filling the tank every one in a while ? Do you really need all that technology and energy just to fill a tank with 2 liters of water in a home that 100% has running water ? How much energy does it take to condensate that much water from the air ? In a science video, you don't think that would have been interesting ? And how much more CO2 is used because of it just to avoid the huge hassle of taking the tank to your sink to fill it ? This video a perfect example to tech bros thinking they are so smart with their fancy degrees (every video we are reminded bro has a chem. eng. degree) to invent stuff nobody needs and overlooking so many things, basically fixing problems that don't exist.
I have a Roomba combo vacuum and mop and it doesn't do this. I replace my tank with cleaning solution like once every 3 months. It's so frustrating how often I have to fill it, it feels like I have no time for anything else in my life. I stay awake at night most nights just in utter fear of the next moment I'll have to refill it and worrying if there's any more cleaning solution in the bottle. Shit... I forgot it this time, pray for me! /s
For that money you could have a plumber hook it up to the water line, for a little extra he might even be able to connect it to the drainage system as well. Now, you use less energy and you never ever have to empty or fill the damn thing.
I hadn't even clocked that it cose $1500+ and this video plays like a bad infomercial with some token physics wrapped around it. I feel like they misplayed their target audience by putting it on this channel since a lot of people here will immediately key on how inefficient that water recycling cycle must be and he doesn't even mention that this "moisture farming" is going to be even less efficient in dry places like Tatooine.
The syringe plunger actually did move out by roughly 1 mm during the pre-boiling heating phase. Water does expand when heated before boiling (and the syringe may have even had a bubble that he couldn't get rid of), so that's not surprising.
Also, the plunger has friction with the syringe barrel. It’s called break loose force and can be very high. I’m disappointed that he performed such a poor demonstration to sell that product.
This is actually a really cool product. I get that you can just get tap water, but this is also basically distilled water without any minerals which is better for cleaning and it does get rid of the chore. If you have solar, the electricity is basically negligible. All the tech and design solutions in it are actually really cool from an engineering standpoint.
An industrial scale process is almost always more efficient than individual scales. Just replacing the water by hand (making use of the massive sewage filtration system) every once in a while is much more energy efficient than boiling and condensing water on site.

I use my dehumidifier to "generate" water in my basement for my laundry bucket and plants. I need to keep humidity lower in summer and might as well put it to use
@opliko Just a note 😋 Also, when it is that damp in the basement, it could stem from drying clothes down there. I don't know if this exact person does this, but I'm sure a lot of people do. Including people in my own family. Therefore, the note 🤙
1:51 That, my friend, is the reason I watch this channel. Instead of just spewing facts at us and telling us that's the truth, and demonstrate an experiment and make us think. We rediscover the same thing that was discovered centuries ago, and that makes the learning experience so much better.
The change in volume with temperature is demonstrated with tides and the use of the Plimsol Line on boats. The cold north atlantic ocean water is much colder than the Caribbean waters and the volume of water increases with this heat. The density of the water also reduces with this temperature increase....thus the Plimsol Line existing. The 'cold' water wasnt really cold, if you do it with refrigerated water from the fridge, then microwave it, you'll see a change in the volume.
I cringe at the energy waste to condense and evaporate water just so that you don't have to refill and empty a bucket from time to time. That idea just seems completely insane.
The truth is, the water does expand before the boiling point. If it's getting hotter then it expands a tiny imperceivable amount. In addition to the liquid water expanding, there is a very tiny amount of water vapor formed when a particular molecule gets extra hot from collisions. It just immediately turns back into liquid water again the moment it bumps into the edges of the syringe or other water molecules since all the other molecules are cooler on average than that particular water molecule. Atmospheric pressure keeps it like this until the average temperature of the water gets hot enough that the evaporated water stays in the vapor phase for more than a few microseconds. This is when the vapor pressure reaches the atmospheric pressure, aka the definition of a boiling point.

But wait! There's more! Buy now! and you can get this for 499.99 in 3 and a half easy payments!
Wait wait, you might wanna respect the temperature and water steam carrying capacity of the air/gas above the liquid water. Those parameters determine the relative humidity and thus the speed of evaporation. That's is also why we can hardly sweat in already humid air
Condensing water would use an insane amount of energy (I think that thermodynamically, to condense one liter, your heat pump needs to extract as much energy as it would take to boil one liter dry). Compared to throwing away the solid dirt, refilling a water tank sounds like a much nicer chore, so they've just eliminated the easy part.
I could not find an unbiased review of this robot. Also, I can't find anywhere that mentions whether it uses compressor or peltier technology for condensation. Either way, it's a lot of unnecessary extra complexity and power use.
although not unbiased since they gave it to me for free, I actually really like it. You don't hear a compressor kick on. But there is a fan that you hear drawing in the air until the tank is full. You can turn it on quiet mode so you don't hear the fan if you want. I have another good mopping robot and it actually is kind of annoying how often I am emptying and filling it. But with this one it has required zero intervention since I've had it (several months). Also I was surprised it works even in my low humidity (less than 30%).
@@davidkrygier511 That's not really very useful information; unlike a light bulb that draws the same amount of power no matter how long it's turned on, a cooling circuit switches on and off. With an 850W rating it's probably a compressor, and that's how much (i.e. the maximum) power it uses on startup, which is only a few seconds. The constant draw is significantly lower, and of course, once the system reaches its desired temperature, or once it's collected all the water it needs, the only power it will draw is what it needs to charge the battery or keep its monitor circuit running. It could also use Peltier modules, as I wrote above, which are significantly less efficient, although 850W, if accurate, seems on the high side for Peltier modules in such a small enclosure, even with forced air. OTOH, since @TheActionLab wrote that he couldn't hear a compressor, it could very well be Peltier.
It’s a tiny air conditioner(except it doesn’t actually cool the air in a confined space because the heat removed just goes back into the area it was taken from)
Wouldn't that second graph actually have at least a little bit of a curve on the end there, James, just like a "square wave" can't actually magically be _perfectly_ instantaneous?
@@wolfsmaul-ger8318: Right, but it still shot up with a straight line, almost perfectly straight up, where I thought there would still be at least a little curve. But... maybe it's good enough for now.
Nope, no curve. Like Ben was saying, the liquid will increase in temperature until it reaches the boiling point, it'll remain the same temperature as heat energy going into vaporizing it instead of raising the temperature, and only when it's all vapor will the temperature start to rise again. So even at the slightest fraction of a degree below the boiling point, it'll be 100% liquid, and at the slightest fraction above the boiling point, it'll be 100% vapor. That's in theory anyway. In real life, the plunger will resist moving out exerting a bit of force on the liquid and raising the boiling point ever so slightly. This force won't be perfectly consistent as the plunger slides down the tube, so the graph won't be _perfectly_ vertical there for that and probably other reasons.
Surely you mean: The minimum wage employee who's manually remote controlling optimus stomps on your vacuum, calls it a 'filthy animal' and then sweeps up the broken vacuum carcass the traditional way..
In 2003, I was travelling through the mountains near McCall in Idaho, and it was so cold that a cold lake that was just above freezing was steaming. I thought it was a hot spring and was told not to take a dip or I'd die. Fun times.
That's a minor thing. The extra pressure only delays boiling by a small amount. What is happening is like this. Water has a "vapor pressure" that increases as it is heated. The atmosphere is pressing on the plunger at 15 psi. Until the water reaches 100 C, it's vapor pressure is < 15 psi, so the plunger doesn't move. After 100 C, the vapor pressure is greater than 15 psi, and pushed the plunger out.
The 3i S10 Ultra takes the moisture from the air and condenses it into water. That is good for re-using it to mop the floor, but it will also dry out the air, which isn't really good for your well-being. It will dry out the mucous membrane which in turn can raise the risk of infections. It also can aid or even cause respiratory illnesses like coughing or asthma. It will also dry out the skin which can cause skin problems like itching or alligatoring/shingling. So, while this is technically a nice thing, it isn't really healthy for humans (and animals?). I have a device that enriches the room with humidity, which should be between 40% and 60% in order to create a healthy indoor environment.
Thank you so much for this video setting the record straight on how humidity works! Many incorrectly say that the air can "hold" only so much water at a given temperature when in reality the same amount of water vapor would exist with no air at all.
What a coincidence. i decided to pull out an old book of experiments from when i was a kid and started redoing these for fun. The first experiment is water evaporation. Less than 5 minutes ago i stated this and you upload this video. great stuff
This is for selling the information on your house layout, what's in it and who's in it to marketing scumbags. Guaranteed the AI is doing a lot more of this with the data than helping the cleaner be more efficient.
wow ! so now you are a vacuum cleaner sales man ? when are you going door to door ? 🤣seriously , that is an amazing machine ! and i always enjoy your videos , learn new things with each and every one . thanks ! 👍
As a physiotherapist I suggest cleaning your house with a classic vacuum cleaner, doing a little bit of exercise in the process. The only useful advance I’ve seen in the last decades was wireless cleaners, is way more comfortable and safe to clean without wires messing around
You can see this phenomena when cooking if a pan of food is partially covered you see the transition and equilibrium phase - if the same pan is uncovered and heated you can only see steam when the heat is removed🤔
I run a dehumidifier in my living room, and it pulls 5 gallons of water every 3-6 days. I end up dumping the water for the plants 1-2x a week. This sounds like a great way to put that water to good use. The major downsides are the expense (~500watts of power draw), it’s loud while the heat pump is running, and it heats the room fairly appreciably. Wonder if the robot mop is the same.
So I guess for this gizmo to work correctly one would better have the AC off, or else little to no water will be collected … On the subject of water collection, I’d ask you to give the 1965 film Flight Of The Phoenix a watch and tell us how with heat this time, one is able to collect water from water poor environments 😊. The video does also explain why car radiator caps are designed to let steam go at certain pressure, over which water in the system would all turn to steam
That's more about the engine being above it's safe operating temperature and providing a path by which the overpressurised water can leave the system without blowing anything else up. If it was made in the last 30+ years, the car should already be giving you a warning it's overheating well before this happens as running overheated for long periods often writes off the engine.
The cyring example is not correct tho. It does move slightly with the vapor pressure at different temperatures. Piston should move around 3% of air volume in the cyringe at 60 degrees
So I have insight on that mopping robot: as someone who has protible air conditioning that can double has dehumidifiers, I can tell you that given the right circumstances, you can pull 10+ GALLONS of water from the air DAILY. that’s with a strongly powered system. A smaller (possibly more passive) one could definitely make a gallon per day to mop the floor. Easily. Even in winter I bet there’s enough humidity to use water vapor for mopping floors.
For condensation I was used to a different model, which relies on the maximum amount of water which air can contain. When you suddenly cool air down like with your metal, then the amount of water the air can hold decreases, and all excess water turns liquid. (Saturation vapor pressure decreases)
yes but air doesn't "hold" water. It doesn't matter what is above the water. The same amount of water vapor will be present at a given temperature. Most people refer to air "holding" water, but it isn't correct, its just a convenient way to say it.
Okay, at 1:51 right now and after giving it a think, you have to specify the pressure over the water. If we're at atmospheric pressure, then none of the water will vaporize until we reach the boiling point because the vapor pressure has to be high enough to counteract the atmosphere and the weight of the piston. If we're in a vacuum (with a piston of negligible weight) then there would be some vapor and it would continue to grow indefinitely at any (reasonable) temperature, since there's no pressure and it can keep evaporating (as long as you're supplying heat). So in the first case, the graph should just be flat until the boiling point.
water from your faucet cost ~5$/m^3 water from a this* cost ~200$/m^3 (1000W giving 1L/h in a damp room and electricity at 0.20$/kwh) *this = a dehumidifier using electricity to cool down a heat exchanger in order to collect water from the air like what is explained in this video
You didn't mention: the friction in the syringe plunger, the change in pressure within the syringe, the relative humidity of the air. But I did skip the giant advertisement at the end.
How does the relative humidity in the air affect evaporation? Probably because a higher humidity means quicker and closer collisions from the water evaporating from a surface, meaning it somewhat quickly goes back into the surface?
@@HelloKittyFanMan For the price of $1900, I don't see that being relevant. It's also probably not going to regulate your indoor humidity like a dedicated dehumidifier would do, it's only meant to regulate the water in its tanks.
@@HelloKittyFanMan It isn't going to prevent you from needing a dehumidifier, so you can't save effort by buying only it and not also dehumidifier. Unless I misunderstood you and that's not what you meant?
If you boil water in closed compartment to 100 Celsius water is still in liquid state but if you open relief valve it becomes steam. In petrochemical industry or plastic industry relief valves are adjusted to that scenario if not tanker or reactor will rapture.
Seems so odd that after robot vacuums being around for so long they still haven't found one that can conquer its true nemesis: stairs. I'm never going to get one if I still need a regular vacuum even if I were to spend all of the effort of occasionally moving around which floor the robot is on.
It would be interesting to see this with the top of the syringe sealed. Then, as the plunger moves, the pressure will increase in the air space, and thus against the plunger, increasing the boiling point of the water. Basically, you would see gradual movement as the water heats (starting above 100 C).
Huh, that mop is kind of cool. I've had a dehumidifier running for a while and it's shocking how much water it pulls out of the air. I've been thinking that there has to be some interesting things that could be done with that water rather than me dumping it down the drain every couple weeks.
I disagree with the graph you showed at 3:03. If the vapor pressure is raising it means there is more vapor, if you keep the temperature constant, sure, the rate of codensation and evaporation are the same, but that's not the experiment. You even said it yourself: "it's solely determined by the temperature of the water, the higher the temperature of thee water the more water vapor there will be".
there needs to be empty space already there. In a syringe with only water there is no space for it to evaporate into. It would have to push the syringe back but it can't do that until the vapor pressure is at the atmospheric pressure, which is the boiling point
Ooh that looks like a refregiration cycle in there. Careful with that, if Alec from Technology Connections sees it he'll probably once again make a super long indepth video on it XD
Did you take account of the friction from the plunger seal in the syringe? I bet the result would be at least a little different if a fictional frictionless plunger were used.
Great infomercial, the tech is interesting enough to make the watch worthwhile. If it had been a roomba review, I would be griping. You have an interesting channel, more so than most on RUclips. Keep it up!
Why is the steam rising from a hot cup of tea or any hot liquid turbulent in nature? Is it because of the movement of the air combined with the difference in the energy of individual steam particles (water vapour)? Can you try placing a steaming cup of tea or water inside the vacuum chamber?

You went down a few notches in the trust dept. You could have at least mentioned the high energy use and told us to make our own conclusions. Not unsubscribing yet but might after next time.
The energy use must be obvious to anyone watching this channel. Would be nice to have the exact number though, so we can compute if the energy costs less than what we make in the time it takes to refill/empty a tank in a non-dehydrating robot cleaner.
How much extra energy does it use on collecting a boiling water, just for you to never have to change the water?
For real. I would bet money that it's 10 times cheaper just to get the water from a tap ... Than waste electricity this way
Heaps of energy, I'm sure. Though that amounts to
Fr bro how can he pay so much electricity cuz he is too lazy to refill water every month and clean dirt tank every week 🤦
@mikeissweet 1$? Boiling and freezing water everyday?
@cupcake_toucher445 not much water and condensing - not freezing.
And if done smart it should not be that much - the heat generated from condensing new water can be used to evaporate the dirty water.
I have a feeling this thing, although well thought out, is so complex, and has so many moving parts, and has subsystems that absolutely have to function correctly, is going to be a maintenance nightmare after about 3 months of use. I hope they've life cycle tested this thing thoroughly.
It's some skymall nonsense for sure
You know they won't be - they're paying youtubers to hawk their e-waste for goodness sake.
The electricity usage to be constantly condensing and distilling water would seem to be an inefficiency.
I did some back of the envelope math, and it costs about $60 per year more than a standard robot mop to operate. The amount of water we're distilling is not very much, and we're not doing it very often really. This said, it is $60 more per year than if you just replaced the water somehow, so it is less energy efficient, it's just nothing astronomical.
That robot is loud as hell. At night, it can sometimes wake you up.
This stoopid thing costs 1900. Just to avoid filling the tank every one in a while ? Do you really need all that technology and energy just to fill a tank with 2 liters of water in a home that 100% has running water ? How much energy does it take to condensate that much water from the air ? In a science video, you don't think that would have been interesting ? And how much more CO2 is used because of it just to avoid the huge hassle of taking the tank to your sink to fill it ?
This video a perfect example to tech bros thinking they are so smart with their fancy degrees (every video we are reminded bro has a chem. eng. degree) to invent stuff nobody needs and overlooking so many things, basically fixing problems that don't exist.
Cry about it
I have a Roomba combo vacuum and mop and it doesn't do this. I replace my tank with cleaning solution like once every 3 months. It's so frustrating how often I have to fill it, it feels like I have no time for anything else in my life. I stay awake at night most nights just in utter fear of the next moment I'll have to refill it and worrying if there's any more cleaning solution in the bottle. Shit... I forgot it this time, pray for me! /s
For that money you could have a plumber hook it up to the water line, for a little extra he might even be able to connect it to the drainage system as well. Now, you use less energy and you never ever have to empty or fill the damn thing.
Having 3 Xiaomi robot vacuum , now I NEED this.
I hadn't even clocked that it cose $1500+ and this video plays like a bad infomercial with some token physics wrapped around it.
I feel like they misplayed their target audience by putting it on this channel since a lot of people here will immediately key on how inefficient that water recycling cycle must be and he doesn't even mention that this "moisture farming" is going to be even less efficient in dry places like Tatooine.
The syringe plunger actually did move out by roughly 1 mm during the pre-boiling heating phase. Water does expand when heated before boiling (and the syringe may have even had a bubble that he couldn't get rid of), so that's not surprising.
Also, the plunger has friction with the syringe barrel. It’s called break loose force and can be very high. I’m disappointed that he performed such a poor demonstration to sell that product.
This is actually a really cool product. I get that you can just get tap water, but this is also basically distilled water without any minerals which is better for cleaning and it does get rid of the chore. If you have solar, the electricity is basically negligible.
All the tech and design solutions in it are actually really cool from an engineering standpoint.
Action you’ve been educating us for years… get your money bro
An industrial scale process is almost always more efficient than individual scales. Just replacing the water by hand (making use of the massive sewage filtration system) every once in a while is much more energy efficient than boiling and condensing water on site.
And all that for ONLY a cool $1900! And $200 off, whoa!
"Thank you to 3i for sponsoring a MAJOR portion of this video". And thank you Action lab, I finally understood how some refrigerators make ice without needing access to plumbing. You are always interesting
This late-night shopping channel is great for falling asleep to.
I jest. Looking forwards to less overtly spoon-fed sponsored videos, and your own mad science next year.
Thanks for all the videos!
I use my dehumidifier to "generate" water in my basement for my laundry bucket and plants. I need to keep humidity lower in summer and might as well put it to use
Thank you for your service 🌱🌱
Note: Drying/evaporating 1 liter of water costs about 0.7 kWh.
It is better to dry outside if possible.
@@jsjs6751 How do you propose he takes his basement outside?
@opliko Just a note 😋
Also, when it is that damp in the basement, it could stem from drying clothes down there.
I don't know if this exact person does this, but I'm sure a lot of people do. Including people in my own family.
Therefore, the note 🤙
1:51 That, my friend, is the reason I watch this channel. Instead of just spewing facts at us and telling us that's the truth, and demonstrate an experiment and make us think. We rediscover the same thing that was discovered centuries ago, and that makes the learning experience so much better.
Lol, the last 3 minutes got auto-skipped.
The change in volume with temperature is demonstrated with tides and the use of the Plimsol Line on boats. The cold north atlantic ocean water is much colder than the Caribbean waters and the volume of water increases with this heat. The density of the water also reduces with this temperature increase....thus the Plimsol Line existing.
The 'cold' water wasnt really cold, if you do it with refrigerated water from the fridge, then microwave it, you'll see a change in the volume.
I cringe at the energy waste to condense and evaporate water just so that you don't have to refill and empty a bucket from time to time. That idea just seems completely insane.
The truth is, the water does expand before the boiling point. If it's getting hotter then it expands a tiny imperceivable amount. In addition to the liquid water expanding, there is a very tiny amount of water vapor formed when a particular molecule gets extra hot from collisions. It just immediately turns back into liquid water again the moment it bumps into the edges of the syringe or other water molecules since all the other molecules are cooler on average than that particular water molecule. Atmospheric pressure keeps it like this until the average temperature of the water gets hot enough that the evaporated water stays in the vapor phase for more than a few microseconds. This is when the vapor pressure reaches the atmospheric pressure, aka the definition of a boiling point.
But wait! There's more! Buy now! and you can get this for 499.99 in 3 and a half easy payments!
Wait wait, you might wanna respect the temperature and water steam carrying capacity of the air/gas above the liquid water.
Those parameters determine the relative humidity and thus the speed of evaporation.
That's is also why we can hardly sweat in already humid air
Condensing water would use an insane amount of energy (I think that thermodynamically, to condense one liter, your heat pump needs to extract as much energy as it would take to boil one liter dry). Compared to throwing away the solid dirt, refilling a water tank sounds like a much nicer chore, so they've just eliminated the easy part.
I could not find an unbiased review of this robot. Also, I can't find anywhere that mentions whether it uses compressor or peltier technology for condensation. Either way, it's a lot of unnecessary extra complexity and power use.
although not unbiased since they gave it to me for free, I actually really like it. You don't hear a compressor kick on. But there is a fan that you hear drawing in the air until the tank is full. You can turn it on quiet mode so you don't hear the fan if you want. I have another good mopping robot and it actually is kind of annoying how often I am emptying and filling it. But with this one it has required zero intervention since I've had it (several months). Also I was surprised it works even in my low humidity (less than 30%).
@@TheActionLab How long does it need to run for that - how much power does it use there?
@@TheActionLab your a garbage channel that makes videos for companies
850watt according to the manual
@@davidkrygier511 That's not really very useful information; unlike a light bulb that draws the same amount of power no matter how long it's turned on, a cooling circuit switches on and off. With an 850W rating it's probably a compressor, and that's how much (i.e. the maximum) power it uses on startup, which is only a few seconds. The constant draw is significantly lower, and of course, once the system reaches its desired temperature, or once it's collected all the water it needs, the only power it will draw is what it needs to charge the battery or keep its monitor circuit running. It could also use Peltier modules, as I wrote above, which are significantly less efficient, although 850W, if accurate, seems on the high side for Peltier modules in such a small enclosure, even with forced air. OTOH, since @TheActionLab wrote that he couldn't hear a compressor, it could very well be Peltier.
It’s a tiny air conditioner(except it doesn’t actually cool the air in a confined space because the heat removed just goes back into the area it was taken from)
Wouldn't that second graph actually have at least a little bit of a curve on the end there, James, just like a "square wave" can't actually magically be _perfectly_ instantaneous?
it is not perfectly straight up but it is also just supposed to be a vague graph
The horizontal axis is temperature, not time. The boiling isn't instantaneous, but the temperature stops increasing until it's all vapor.
@@wolfsmaul-ger8318: Right, but it still shot up with a straight line, almost perfectly straight up, where I thought there would still be at least a little curve. But... maybe it's good enough for now.
@@BenAlternate-zf9nr: I wasn't saying it was, right? It just seemed like that spike should have at least a little curve.
Nope, no curve. Like Ben was saying, the liquid will increase in temperature until it reaches the boiling point, it'll remain the same temperature as heat energy going into vaporizing it instead of raising the temperature, and only when it's all vapor will the temperature start to rise again. So even at the slightest fraction of a degree below the boiling point, it'll be 100% liquid, and at the slightest fraction above the boiling point, it'll be 100% vapor.
That's in theory anyway. In real life, the plunger will resist moving out exerting a bit of force on the liquid and raising the boiling point ever so slightly. This force won't be perfectly consistent as the plunger slides down the tube, so the graph won't be _perfectly_ vertical there for that and probably other reasons.
The science behind it is really cool. But, frankly, I don't have fancy mopping robot money.
"Green light technology"
So... reflection?
Seems like a lot of hoopla for a lot of energy waste.

Thats the very light duty floor droid. That might not fare well as the experiment clean up droid.
In 2003, I was travelling through the mountains near McCall in Idaho, and it was so cold that a cold lake that was just above freezing was steaming. I thought it was a hot spring and was told not to take a dip or I'd die. Fun times.
"green light technology" lol
I mean it's technology, and it has a green light. I don't see a lie. ¯\_(ツ)_/¯
The piston is sealed with rubber and its very hard to move, that's why it moves only when water is boiling
That's a minor thing. The extra pressure only delays boiling by a small amount.
What is happening is like this. Water has a "vapor pressure" that increases as it is heated. The atmosphere is pressing on the plunger at 15 psi. Until the water reaches 100 C, it's vapor pressure is < 15 psi, so the plunger doesn't move. After 100 C, the vapor pressure is greater than 15 psi, and pushed the plunger out.
The 3i S10 Ultra takes the moisture from the air and condenses it into water. That is good for re-using it to mop the floor, but it will also dry out the air, which isn't really good for your well-being. It will dry out the mucous membrane which in turn can raise the risk of infections. It also can aid or even cause respiratory illnesses like coughing or asthma. It will also dry out the skin which can cause skin problems like itching or alligatoring/shingling. So, while this is technically a nice thing, it isn't really healthy for humans (and animals?).
I have a device that enriches the room with humidity, which should be between 40% and 60% in order to create a healthy indoor environment.
Thank you so much for this video setting the record straight on how humidity works! Many incorrectly say that the air can "hold" only so much water at a given temperature when in reality the same amount of water vapor would exist with no air at all.
Never thought that a science channel would be sponsored by a vacuum cleaner company 😅
What a coincidence. i decided to pull out an old book of experiments from when i was a kid and started redoing these for fun. The first experiment is water evaporation. Less than 5 minutes ago i stated this and you upload this video. great stuff
You DONT need AI for this. We have been doing this kind of detection for ages with simple cameras and algorithms.
you do need ai to detect dog shit, cables, socks, toys, etc. You also need ladar and this expensive garbage robot doesn't have one.
This is for selling the information on your house layout, what's in it and who's in it to marketing scumbags. Guaranteed the AI is doing a lot more of this with the data than helping the cleaner be more efficient.

wow ! so now you are a vacuum cleaner sales man ? when are you going door to door ? 🤣seriously , that is an amazing machine ! and i always enjoy your videos , learn new things with each and every one . thanks ! 👍
As a physiotherapist I suggest cleaning your house with a classic vacuum cleaner, doing a little bit of exercise in the process.
The only useful advance I’ve seen in the last decades was wireless cleaners, is way more comfortable and safe to clean without wires messing around

You can see this phenomena when cooking if a pan of food is partially covered you see the transition and equilibrium phase - if the same pan is uncovered and heated you can only see steam when the heat is removed🤔
I run a dehumidifier in my living room, and it pulls 5 gallons of water every 3-6 days. I end up dumping the water for the plants 1-2x a week. This sounds like a great way to put that water to good use.
The major downsides are the expense (~500watts of power draw), it’s loud while the heat pump is running, and it heats the room fairly appreciably. Wonder if the robot mop is the same.
So I guess for this gizmo to work correctly one would better have the AC off, or else little to no water will be collected …
On the subject of water collection, I’d ask you to give the 1965 film Flight Of The Phoenix a watch and tell us how with heat this time, one is able to collect water from water poor environments 😊.
The video does also explain why car radiator caps are designed to let steam go at certain pressure, over which water in the system would all turn to steam
That's more about the engine being above it's safe operating temperature and providing a path by which the overpressurised water can leave the system without blowing anything else up. If it was made in the last 30+ years, the car should already be giving you a warning it's overheating well before this happens as running overheated for long periods often writes off the engine.
The cyring example is not correct tho. It does move slightly with the vapor pressure at different temperatures. Piston should move around 3% of air volume in the cyringe at 60 degrees
Are you talking about dissolved air
Ok sure, now how much energy does that use compared to producing the water and transporting it through the pipes in the usual way near you?
apparently the device is rated at 850 watts, but nothing about which function is specified
So I have insight on that mopping robot: as someone who has protible air conditioning that can double has dehumidifiers, I can tell you that given the right circumstances, you can pull 10+ GALLONS of water from the air DAILY. that’s with a strongly powered system. A smaller (possibly more passive) one could definitely make a gallon per day to mop the floor. Easily. Even in winter I bet there’s enough humidity to use water vapor for mopping floors.
What a mind blowing cleaning vacuum design! But really did you drink your evaporated and re-condensed dirty water?
Thank you for the graphical explanation. Makes it so easy to understand. Cheers!!!
For condensation I was used to a different model, which relies on the maximum amount of water which air can contain. When you suddenly cool air down like with your metal, then the amount of water the air can hold decreases, and all excess water turns liquid. (Saturation vapor pressure decreases)
yes but air doesn't "hold" water. It doesn't matter what is above the water. The same amount of water vapor will be present at a given temperature. Most people refer to air "holding" water, but it isn't correct, its just a convenient way to say it.
This amazing device is WAY ahead of its time. A taste of things to come in the near future. I love Action Lab videos.
Okay, at 1:51 right now and after giving it a think, you have to specify the pressure over the water. If we're at atmospheric pressure, then none of the water will vaporize until we reach the boiling point because the vapor pressure has to be high enough to counteract the atmosphere and the weight of the piston. If we're in a vacuum (with a piston of negligible weight) then there would be some vapor and it would continue to grow indefinitely at any (reasonable) temperature, since there's no pressure and it can keep evaporating (as long as you're supplying heat). So in the first case, the graph should just be flat until the boiling point.
The boil restriction reminds me of rush hour on subway train: There's nowhere to move so nobody staggers about.
Dont know why you find the sudden rise in volume surprising
water from your faucet cost ~5$/m^3
water from a this* cost ~200$/m^3
(1000W giving 1L/h in a damp room and electricity at 0.20$/kwh)
*this = a dehumidifier using electricity to cool down a heat exchanger in order to collect water from the air like what is explained in this video
You didn't mention: the friction in the syringe plunger, the change in pressure within the syringe, the relative humidity of the air. But I did skip the giant advertisement at the end.
How does the relative humidity in the air affect evaporation? Probably because a higher humidity means quicker and closer collisions from the water evaporating from a surface, meaning it somewhat quickly goes back into the surface?
Thanks for the breakdown. Now we can make our own.
Various open-source projects could be compiled to make one.
Someone just need to design a dishwasher with a robot vacuum station underneath and forget all the extra doodads.
Next, robots that can bring you a glass of water without going to the sink! 😮
Must smell nice when the robot collects cat shit and then the unit boils it 🤣🤣🤣🤣
So it's a dehumidifier then. Yup!
"So... then"? What if you saved yourself some effort because ya only need one or the other word?
@@HelloKittyFanMan For the price of $1900, I don't see that being relevant. It's also probably not going to regulate your indoor humidity like a dedicated dehumidifier would do, it's only meant to regulate the water in its tanks.
@@5467nick: I don't even see a connection between what you're talking about and what I was talking about.
@@HelloKittyFanMan It isn't going to prevent you from needing a dehumidifier, so you can't save effort by buying only it and not also dehumidifier. Unless I misunderstood you and that's not what you meant?
@5467nick : I wasn't even talking... 1. about that, or 2. to you.
If you boil water in closed compartment to 100 Celsius water is still in liquid state but if you open relief valve it becomes steam. In petrochemical industry or plastic industry relief valves are adjusted to that scenario if not tanker or reactor will rapture.
Seems so odd that after robot vacuums being around for so long they still haven't found one that can conquer its true nemesis: stairs. I'm never going to get one if I still need a regular vacuum even if I were to spend all of the effort of occasionally moving around which floor the robot is on.
I do a type of void speed painting where I turn my crayon into a universal transponder. I do believe you can take anything out of emptiness.
if you skip back (with the left arrow key) when the syringe is in the microwave oven you can see there's an increase in volume, albeit minimal.
It would be interesting to see this with the top of the syringe sealed. Then, as the plunger moves, the pressure will increase in the air space, and thus against the plunger, increasing the boiling point of the water. Basically, you would see gradual movement as the water heats (starting above 100 C).
Interesting video, James. How much does this thing cost: $2000?
Happy Christmas!
Huh, that mop is kind of cool. I've had a dehumidifier running for a while and it's shocking how much water it pulls out of the air. I've been thinking that there has to be some interesting things that could be done with that water rather than me dumping it down the drain every couple weeks.
Ah yes, my favorite, Water and Air.
I disagree with the graph you showed at 3:03. If the vapor pressure is raising it means there is more vapor, if you keep the temperature constant, sure, the rate of codensation and evaporation are the same, but that's not the experiment. You even said it yourself: "it's solely determined by the temperature of the water, the higher the temperature of thee water the more water vapor there will be".
there needs to be empty space already there. In a syringe with only water there is no space for it to evaporate into. It would have to push the syringe back but it can't do that until the vapor pressure is at the atmospheric pressure, which is the boiling point
@@TheActionLab oh now that makes sense. Thank you for explaining!
Wireless package delivery is pretty easy, but you can't teleport the water either.

It must be real rough in ActionLabland, boss just straightfaced the line "green light technology".
Did you take account of the friction from the plunger seal in the syringe? I bet the result would be at least a little different if a fictional frictionless plunger were used.
It gets wet by itself and it sucks. Two outta three ain't bad.🍽
Great infomercial, the tech is interesting enough to make the watch worthwhile. If it had been a roomba review, I would be griping. You have an interesting channel, more so than most on RUclips. Keep it up!
Woops left the dog at home came back and my expensive robot vacuum is in pieces everywhere
This robot is pure luxury....it spoils energy to catch water which is already available at your pipes.
Have you let a little can of dust for Ottis during the panteone season?
2:13 there is a clear volume increase
Yeah, I was about to comment this
Will Thunderf00t debunk that thing? 🤔
Why is the steam rising from a hot cup of tea or any hot liquid turbulent in nature? Is it because of the movement of the air combined with the difference in the energy of individual steam particles (water vapour)?
Can you try placing a steaming cup of tea or water inside the vacuum chamber?
So, the robot station is like a dehumidifier? That device pulls water from the air and is collected in a container. Am I close?
