Careful, Doctor! If you keep teaching, you might just foster minds that would save the world!
Years ago, Dad borrowed a little book that was filled with all these interesting inventions (like the farmer who used an old silo as a methane generator from pig muck). Dad came across this page about a solar still. It looked like a little house with a hip roof but it was all glass. Running parallel with the two shorter walls were two short internal walls that did not reach the roof but were sealed at either end to the large walls, making a chamber on either side of the 'house'. The idea was that if you filled the centre 'room' with water, the sun would evaporate the water, the water would run down each roof hip and collect in the two outer 'rooms'. There were rubber bungs at the bottom of each room for collecting the fresh water and one at the top for fill the main room. Dad built one and it did indeed work, albeit slowly. Now if we had some of this foam and felt in the centre room, I bet it would have worked way faster.
Very interesting. So many times when MIT researchers dive into a problem, they develop an innovative and practical solution.
It is not only the salt, in the long run, it is microbial growth.
So use nature and replace the felt with algea😉
Every aircon unit pulls water outof the air.
You can desalinate sea water with tower & a pump.
You can make it more efficiant with some solar heating to remove dissolved gasses, then use the tower column pressure to vaporise the water. Being warmed reduces the vaccume needed. ReCondensation occurs by heat exchange from the output vapor back to the incomming sea water through a normal distilation pipes. Of course, you have to return some salt enriched water back to the sea which is also a feature of filtration desalination.
Thank you for the wonderfully good news, Robert. I hope you and your family are having a great Monday. Sheila Mink in New Mexico
You are a legend Robert. Thank you for sharing your wisdom. You are an absolute Wizard and we all love you. All over the world.
Really? Wizard? This is about the weakest description of a scientific process ever. Almost worthless.
The only thing worthless on this channel is your opinion. You wish you were as clever as Robert.
Interesting idea. Might be useful for a project I was thinking about: a solar rechargeable desiccant dehumidifier.
Yes the MIT paper uses a membrane actually and it’s actually a pressure build up from solar energy the pushes fresh water through and the salt flows away it’s very neat. Because it could be powered by heat from evacuated tube collectors which would be much more efficient. Also your cooling panels can provide additional power to the system I think by cooling the fresh water side you could decrease the pressure over there helping water pump through the membrane. Also desicant dehumidifier idea is awesome. Another advantage of this is that it produces mineral free water which could be used in terracotta evaporative coolers without leaving a mineral build up. Terracotta cooling has similar performance to the radiative cooling panels and would be very complimentary systems. I love your work btw
You and Tech Ingredients are like a couple of old school jazz musicians riffing on each other and I am here for it 😂😂
Too much accent.
Too much 'wau-tuh'.
Too much 'this sounds too much like a guy who likes to hear himself talk.'
Is the article open access? Seems like it requires you to pay. Anyone have any ideas why?
Use concentrated sun, and basically a greenhouse with sea water pumped through a radiator in the ceiling. To condense the water vapor on and collect it!
Did he say solar still? Now I'm getting new ideas on how to adapt this technology. 😎
Thanks, Robert. You're a muse for the ages.
I read about this already. I thought of you and your channel right away. I'm looking forward to you making one for us. Very exciting discovery.
Solar still idea for better efficiency: Black reservoir, curved glass lens solar magnifier, under drip point of lens glass collector and tube for funneling condensed water out of heated evaporation chamber. Control water feed into chamber with controlled drip rate to maximize the surface area to water ratio. Periodically flush evaporated excess salt build up out with excess inflow rate and opening flush exit valve.
I wondered why a lens isn't used to heat up the water. Then again I didn't calculate anything to find out the answer myself. Sounds like a wonderful idea at first glance.
@Robert Murray-Smith. As a kid I tried to make a dome with reflective sides that focused sunlight onto a floating hot-plate that was washed by wave action to remove the salt residue. I was discouraged by those who know more about these things. Still I also thought, that with the use of tubing that was, in parts reflective and non reflective, the water vapour might be transported a considerable distance. This episode brought all that happy philosophising rolling back. Thank you.
Another way of evaporating water quickly, abet not input energy free, would be to use a babbington atomiser. Same as a babbington burner... just with water rather than oil.
Tiny hole in a pipe. Fluid passes over outside of hole. Inside of pipe connected to source of compressed air.
The spray of droplets has massively increased surface area for evaporation to happen from. I would be surprised if salt would drop out as crystalls, Sally water more likely. Could likely be separated out by a centrifugal filter.
When I tested such a while ago I was getting evaporatoration rates for tap water of about 30l/hour. I was doing it outside in summer, and as humidity was increased towards 100% RH, here was a fair temperature drop in garden.
Filters drive the costs up, his point was this tech keeps the cost down.
This is similar to the way that snow machines germinate snowflakes! Great idea 👍
@troywhite6039 filter membranes not best re cost, but a centrifugal filter to separate moist air from water droplets, need be little more than a large diameter drum with a tangential inlet. Air and droplets fly into through that inlet. Being heavier than air water droplets containg the salt want to continue in a straight line and make contact with the walls and drop out of the air flow, and run down to the bottom.of drum. Moist air can make it's way out of a vent at top.
In the hot equatorial regions Solar desalinization is very practical. Nuclear desalinization is eminently practical and provides electrical power as well. We're not short of water, we're short of desire to solve the problem.
Here’s one for you coach! At night in the desert by the ocean pump salt water into black ABS pipe. The pipe is flat and only about half to 3/4 full and can be configured in a serpentine or a manifold. Pull a partial vacuum releasing some or the bulk of the dissolved gases in the water. The other end of the manifold has a reverse P-trap that has no water in it. After the P-trap the pipe runs back into the ocean. The sun heats the ABS pipe, the partial vacuum boils the water under 100 and the steam condenses in the black pipe under the ocean like a heat exchanger. This condensation will help maintain the vacuum. At night flush the pipe out and diffuse the brine far into the ocean. 🎉
You might want to try this on a very small scale because there are a few holes in your idea, especially revolving around your idea of holding a vacuum. I'm not trying to diss you, just suggesting that there are a few things you aren't taking into consideration so some small-scale experimentation might illustrate the problems you'd experience at larger scale.
Phytoplankton that we depend on for the oxygen we breathe are extremely sensitive to changes in salinity. If we want to desalinate water on a large scale, we need to figure out what to do with the brine... Half the reason our freshwater is in this state is because of this mentality that rivers and the ocean are nature's toilets and landfills.
Pumping gas takes a lot more energy than pumping liquid. Same will apply to pulling vacuum on a gas.
It should however be possible to pump water up to fill say a tube that's say 30m high. Then seal the top of, and open a valve to atmosphere at the bottom, alowing water to drain. Pressure at top of water column will then be reduced by whichever the smaller of, pressure equivalent of "30m of water", or vapour pressure of water for the temperature.
Retain the brine for salt production right next to the desalination site. Water and salt production in one place. We need both.
@@cheyannei5983 I like your comment. Apparently you know a thing or two about desalination.
Can ionization be employed in disposing of the brine? City landfills require covering trash with dirt. Can that dirt be partially comprised of brine ?
I really enjoyed that presentation Robert. Your illustrations and examples are excellent and of course it's always extremely helpful to have an endearing personality with intelligence. Well done.
You must be his best friend to be so glowing about such a mediocre presentation.
@@delavan9141 The only thing I know of Robert is what I found here.
Hi Robert, I think I've found where the waters going! down here in Cornwall "liquid sunshine" give or take we get two dry days for a Summer and 362 days of something wet!
I had this solar science kit and there was a booklet inside that talked about some lake, I can't remember the name, where the brine stayed under some deep, while some fresh water stayed above. There was a warning for divers because the brine got very hot and still its density was high and didn't rise on top of the fresh water. So you could casually swim on fresh cool water but dive into scorching brine a few meters below.
I don't know why they didn't mix, nor diffuse, nor rise by convection.
The vapor compression system patented by Sears in the 1980's is the solution to cheap fresh water production from sea water. It was reintroduced by Dean Kemen to solve the water supply in Africa and ended-up in Coke Cola's hands to disapear.
Thank you for linking the paper, Rob!
Brilliant, thank you for sharing this.
I love the idea of using thermosiphon & salinity as the pump.
Love the video! Their version seems to use a submerged filter to allow water vapour down through which I guess allows them to avoid any salt build up at the evaporation site. I'm not sure if the felt and oasis would quite achieve the same thing? I may be misunderstanding though
Fantastic video, thank you.
Does the water free of polluant from foam and flet or anything else that could be used?
Not getting cancer from it or ingesting heavy metals or super toxic elements.
In 1969, just before Col Gaddafi did us a huge favour and kicked us out, I learned about the stone-and-cup while on RAF desert survival training in the Great Libyan Desert. Of course we had no access to seawater, so we had to use a much more personal liquid!
One obvious way to save potable water would be to build simple roofs over the aqueducts carrying drinking water to LA and other cities in hot climates. Shade would reduce evaporation by a significant amount just by employing this simple and relatively cheap method.
Fresh water,
Why I'm building my off grid energy sys. Using a dehumidifier as my final dumpload so I don't have to waist any power sending it to ground.
Using solar panels and multiple wind turbines can get into some times of way more input than the system can hold or store so having a extra
Another fine example of your ability to cut to the heart of the issue and make it so everyone can understand how it works and inspire us to improve our world. On a side note, trees are great sources of water. The bushcraft skill of putting a clear plastic bag over the green vegetation on a tree or other flora is a very efficient way of getting water in nature. I wonder if you might be interested in giving it a go for comparison sake. Love the videos you make and am always eager to see what you have up your sleeve for the next thing. Cheers
Hey, I just heard about that trick, but the issue was, I couldn't find a plastic bag big enough, plus, using a small one gave me a drop or two during a couple of hours.
Where do you get truly massive plastic bags from? Thanks!!
I think more small ones is better or you end up killing your source. This isn't for large scale. It's just for survival type situations. @@DoNotPushHere
@@8ank3r yup but for a couple drops I couldn't imagine how I would be able to survive
@DoNotPushHere
Instead of a bag think, black tube, black panels, black painted cement pool, black painted pond, a deep lake that uses millions of black balls was used in one experiment.
I learned about that method in the Queensland State Emergency Service!
Thanks for bringing this development to our attention. Maybe there's hope for the species after all.
Make solar desalination barges and float them off coast of where ever needed.... could also grow crops the same way.
Excellent - thanks!
Where does the salt go that is left behind from evaporation? Does the saline solution just get saltier and saltier as the water evaporates from the saline solution?
There are many solar desalinization systems which are very cheap, and very energy efficient, using solar power on flat panels that track the sun.
Column, sponge, water, clear tube.
You want the sponge to be below the water, but you don't want the sponge fully submerged for several reasons, you do the old science trick of using a in this case clear tube under water allows one to have a kind of air pocket, you put the sponge down in there to suck up the water.
Heat tube sponge = evaporation, have this condense on a nice rock bed to extra filter + add in minerals and taste.
The reason for the tube and the sponge is well rather several things. One Oil floats on the top of water and if oil gets on your sponge = game over.
2 you have a increase atmosphere situation happening inside the tube.
3 you have the potential to insulate the inside of the tube in several fashions 'aluminum heat shroud on one side?
4 you control where the water goes when it evaps 'this is important'.
It's always the simple solutions (pun intended) that are the best. Fantastic!
Terrific ! I know you know what I am going to say next - how do we scale this up to fill the lakes in drought ridden countries ? Thank you as always for passing on knowledge and inspiration. You might have just saved the world !
@queenstreetsystems
Since MIT invented it, the scale up question needs to be put to them.
@@user-jk1dh2zi7h
a) how do we learn to govern as individuals "race wide"?
b) list the names of the authors of this research.
Beautiful idea sir. Wish a wealthy person would finance an off grid camp for homeless people that do not want to live in conventional housing. They could employ your ideas to sustain themselves.
Your teachings just might ignite the spark some of them need to recharge their self esteem.
👍 this is great for industrial use near the sea
but what if we reverce this?
as in (free nrg) refrigiration to condence the clouds in a high humidity invironment
for single households? ^^
Robert, this is brilliant and revolutionary. Please consider constructing one by the seashore and testing it over a period of weeks.
Go ahead, no one is stopping you.
@troywhite6039 I don't have the expertise. Robert is a superb innovator. I'd be willing to contribute toward a working model. It would be exciting to see him recreate and improve upon MIT's design.
If you have offshore energy, it makes sense to use any excess for desalination.
Thought of this,have invention on a small scale,gets fresh water&salt utilizing both ends of the process to the fullest of value.👍
Instead, an electrical current is applied to the flow, and this “shock electrodialysis,” as it's called, separates the water into ever saltier and fresher flows, running along next to each other in the pipe. Because the current affects the charged salt particles, they just move off to the side.
I was thinking that we could build very well controlled sea water canals into evaporation lakes in deserts, they could be strategically placed so the prevailing winds carry the water vapour where we need it to go. If all the oceans were perfectly still and I dropped a small stone in... does that disprove the "you can't get more out than you put in" argument?
May I humbly suggest searching TH-cam for Laguna Salada Agess. It has the highest evaporation rate in North America if not the world. When it’s flooded, it increases precipitation in the Colorado River watershed by 15%. Great news for the desert southwest.
Curious if this could be combined with some form of solar powered flow battery?
my thought was to lay a big pipe 700 meters deep in the ocean with a reverse osmosis filter at the deepest point, so the natural water pressure down there would do the job of pushing water in through the filter... would just need a pump to pull the clean water out and up to ground level... although i guess that pump would need a fair bit of power...
Phenomenal
Status of the Magma Energy Project
Dunn, J. C. (Sandia National Labs., Albuquerque, NM.)
Abstract
The current magma energy project is assessing the engineering feasibility of extracting thermal energy directly from crustal magma bodies. The estimated size of the U.S. resource (50,000 to 500,000 quads) suggests a considerable potential impact on future power generation. In a previous seven-year study, we concluded that there are no insurmountable barriers that would invalidate the magma energy concept.
(Current global energy demand is approx 600 quads.)
Mimicking nature sounds like the way to go! I have a well, best water on the planet in my opinion, I use a water-to-go bottle with its carbon filter when away from home, it makes tap, river and still water safe but can't handle salt B-)
Sounds very promising - providing the end user is near the ocean. A big part of the problem with providing an adequate supply of fresh water is the staggering quantity needed. A pipeline can transport an adequate amount of natural gas or petroleum for ordinary needs, but transporting fresh water inland is orders of magnitude more challenging. And going from the ocean, it will of course be going uphill.
If only we realised just how precious water is! Reducing consumption could halve the requirements.
No water shortage up here in Seattle. Good time Charlie's got the blues.
The greatest problem facing all desalination technologies is not addressed here. That is, what do you do with the brine produced? It is highly toxic and can’t be discharged back into the ocean. The best solution so far is injection into subsurface salt water pressurized lake-like layers in the earth. Alternatively the brine can be dried completely to salt which creates its own problems. What are your thoughts?
4-6 liters per hour per of sun in half square meter means that the sun must give around at least 4*750 (aproximation of the energy required to distil 1 liter of water) = 3000W, in just half a meter, that means that they are assuming:
the sun does give 6kw per sq meter ( 6 times more that the most optimistic realistic condition or 3 times assuming that the evaporation is 100% efficient and the water only changes phases without a change in temperature). and that is using the low estimate.
assuming a second system to recover the heat in the distilled water that then is moved back to the system to increase efficiency, which would mean that you have to deal with heat exchangers.
this is just a optimized solar still with a pump attached with the classical MIT spin of "we cannot know the enthalpy of water before a round of investments". at this point, the MIT has a track record of incompentence in this field. like when they reinvented the dehumidifier and failed the prediction (that was about as wrong as this) for one magnitude, or the dissecant system, that also failed because they could undestand that introducing a dessicant didn't change the energy required to get the effective water.
If we used up all the ground water and we move on to desalination of ocean water - how long before that dries up?
Great news. Thanks! :)
I am planning to use fltered lavada water in my house for washing and a solar still for the drinking water. I won't have a problem with salt so this should work indefinitely for me.
Left field idea. Water makers run at approximately 800 psi. What if an empty steel pipe was sunk to a depth of 550m, into the sea, this depth creates 800psi. The bottom of the pipe had a filter membrane that would act as a water maker without the need for any power to produce the pressure. The filtered water would travel up the inside of the pipe then pumped to a reservoir. Similar to what happens when you put a straw into a water bath perpendicular. If you keep a finger over the top of the straw, then remove it the water quickly charges up the straw to equalise the external pressure.
Happy to be shot down with physics here. Yes power is still needed to pump the fresh water from the pipe. What strength pipe/membrane filter would be needed. How to clean the membrane. I’m sure there’s a flaw in the idea, but open to a response.
A tidal pump could be designed to not need electricity but you still have mechanical parts to maintain so there's some costs.
What is covering the windows in the back ground?
This kind of thing along with cheap/free energy are the only things that can possibly lead to peace among humans.
I'd to ask you a question, if I may. Do extreme electrical storms in the atmosphere create water (as rain) from its constituent parts?
No. Water is H20. While there is a lot of O2 in the air, free H2 is only there in trace quantities.
I have seen global lightning maps, animated. Lightning is always happening somewhere -- it's virtually non-stop. So if H2 did accumulate in the atmosphere, lightning would give the spark to make that hydrogen recombine with oxygen, producing water, until the hydrogen is exhausted. In steady state, there is no significant generator of hydrogen to replenish.
Technically, the answer to your question could be argued as "yes", by the means I described. But far and away, the practical answer to your question is "no".
Thank you for that explanation @@PeterLawton
Interesting video. Just thought I'd share an idea I got. Perhaps you might like to try using that foam as a solid electrolyte with an electrolyte wicked into it.
Hey Rob, it's all good and all but I have one important question the carbon felt and this green wicking thing will logically be full of salt... At a specific point in salt concentration the salt will crystallize in that green thing and eventually in the carbon felt and it might then stop working. What will you do? Throw it away or regenerate it because it takes also energy for both. Then I would love to know how much energy it takes to "regenerate" the set up and how much energy it takes to produce the components (carbon felt, green wicking thing and the recipient ) 🤔
I was wondering this myself but I think he was just demonstrating one way to wick the water up for faster evaporation as a demonstration not as the only final solution. I haven't gone over the MIT paper yet but I don't think that is part of it, I could be wrong.
The main idea is to evaporate out of the brine as quickly and efficiently and cheaply as possible without have materials clog up. The constant flow of fresh brine at the wicking layer might slow or prevent that.
What are the effects of having PTFE in a heated environment in contact with water you intend on drinking? Teflon isn't exactly known for its health benefits when heat is applied.
LOL
Perhaps you could speed up the process by placing Fresnel lenses over the material to concentrate the suns rays and generate significantly more heat from the sun. That would be a cheap multiplier of efficiency.
thx!!
Ya know I've also heard of using magnetics for desalination hmmm...
80’s kids might remember “voyage of the Mimi” with Ben Affleck.
One problem, albeit minor, is that having some mineral content in water is very healthy; distilled water is domestically only considered fit for machine use or cleaning. I don't think it would be a massive problem, as the areas this could help the most are those with poor access to water and access to poor water, but improving the mineral content would still be a long-term consideration.
Watercube tm in Tampa Florida I have heard of 🎉
I'm 50 seconds into the video and feel to comment. Water also comes from what's known as "Primary Water" in the earth's crust. I believe it's about 3-5x the amount of water in all the oceans combined, and it's fresh, pure water. I have a lot of info on it I received from those who tap into it. A fascinating subject and there was a news article about it I saw a few months ago. But, like oil, those profiting off it need to make it appear scarce in order to charge for it like Nestle and other major corps do, and gov'ts want to control water and food to control the populations.
Finally the word is getting out. Ty
Not wrong on that info, if they only knew.
@@yahnferral9163 Frankly, I'm surprised anyone here would have even heard of Primary Water as it's been so effectively suppressed for so long, so thanks for your comment.
🤓🤓🤓
I think you have a misunderstanding about water trapped in the Earth's crust, most water in the crust isn't in some pockets or anything easily accessible, it is bound in minerals, (excluding aquifers both a small percentage of the water and clearly not what your talking about since it's still part of the water cycle) you can't just drill for that water... You basically have to mine materials and then heat them to the point that they release the stored water, this is a task more energy intensive than just doing desalination... The only case I can think of where this makes any sense is some post-apocalyptic world where we have made the groundwater so toxic or so radioactive that it can no longer be used in any form even after evaporation(in which case I do not understand how we're even alive as a species)
Their is no financial incentive to hiding this, it has been known for at least a century it's just so cost intensive to be useless, no one is mining 200 liters of rock from a km down in the crust to then have to spend energy heating it or using chemistry to produce 1 liter of water... If we are mining for materials that deep we're not going to mine for water
Awesome video!
ive always been abit confused when it comes to what we need from water, like ive always been under the impression that you need minerals in the water and that distilled water would leach nutrients from your body,
what do we need from water? or should i say in water
That's why they add back into the clean, pure water about 5% sea water to get those minerals. Great question.
@@thirsty_dog1364 oh right I didn't think of that I thought it woul be like put cut up fruits in there with some juice and let it sit or something, this tiny bit of information is what I've looked for forever and you explained it so concise thank you :)
We need certain trace minerals in the water not only to replenish what the body needs but because pure distilled will not conduct electricity which our body does us being electrical beings. Alsosome of the cells of our body can explode and become damaged with distilled water which has a density property that over pressurizes the osmosis transfer too quickly. Drinking water needs to be as close to our cell makeup as possible too be less damaging and more healthy. The less oxidation the better to prevent inflammation. You can infuse plants and fruits and minerals and salts in distilled water to bring it back to an electrically and more dense healthy level also which is an added cost but most commercial applications do not want to add more cost than necessary. After all alot of this water gets wasted for other things besides drinking, like flushing toilets.
There is also a mega project in the desert to "regreen" (/!\ Greenwashing?) it with a giant dome glass house...
i had been told the floral form (which is what we use for arrangements) is highly toxic and bad for the environment, is that untrue?
What about the chemicals leaching in from the materials?
This foam is available generically as 'floral foam' and is a fraction of the price of the Oasis brand foam.
Which model works during winter?
I've always wondered since desalination plants are so energy demanding? Why don't we utilize modern advanced nuclear energy options to power desalination plants? The more i learn about our power grid, the more i realize that modern nuclear energy is our best option. Small form reactors, LFTRs, Thorium Reactors, molten salt reactors. Utilizing our advanced technology, Improved engineering & material science. Using our greater understanding of safety & well made designs. We have so much more advanced computer technology & robotics that can be used. It feels like even tho tons of advancement has occurred with engineering designs, safety measures, etc. It still doesn't matter to most people. It's like most people are ingrained with a natural negative response when talking about nuclear energy.
We need to heal from the trauma of our past. See & learn that those things only happened solely from us not understanding what we were doing when it came to nuclear energy at the time. We didn't have advanced enough technology, material science, engineering, safety measures, understanding of how to go about everything, etc. This source of energy will greatly help the world improve towards the future and lowering emissions. More than anything else could, while also providing a very stable electrical grid system. Currently we have alternative energy options but the majority of our grid is powered off of fossil fuels and emission producing sources of energy. We will be so much better going forward commiting to modern advanced nuclear energy options.
It will really allow places to be much more energy independent. Less reliant on fossil fuels. They'll have efficient, stable electrical grids and the rest of the grid could experiment with alternative power sources, etc.
We know if we reduce the atmospheric pressure of water it's boiling temp goes down. I wonder if reducing the pressure of water enough that the outside temp would cause the water to boil would be highly efficient for solar desalination?
This is way bigger than just desalination. This purifies the water too
There was an Australian scientist who did his PhD in the States who, about 8 years ago, developed a long term stable (tested > 2 years) open, ambient atmosphere bioreactor that could desalinate water to ANZAC drinking standard at a rate of about a megalitre a day for a cost of about .001 cents per liter. He couldn't get anybody interested in taking the tech forward and eventually got disheartened and went to work on something else. Too many big players in the desalination industry were making too much off ridiculously expensive and unreliable RO tech. I know about it because I was one of the scientists who did independent checks and validation on the science.
Wonderful technology! Now if only they could invent a technology for balancing the volume in videos across clips! 🙂
The problem is not a lack of water, it's an excess of humans.
Exactly.
Robert, your video clearly shows that the baking dish with the carbon felt layer was exposed to the air during the experiment and the media in the other dish was completely submerged, effectively just being a dish with water in it. Maybe I'm Wrong but, that seemed a little bit silly for a comparison.
Check out the Whisson Windmill, from Max Whisson in Western Australia. He invented this years back. For something that had interest from every corner of the globe it never took off. But the device works. It has been proven.
He didn't invent the MIT process. He invented extracting water from the atmosphere not desalination from ocean water.
I recently encountered a thought-provoking book, "100 Reasons Water Is Not H2O" by Peter Peterson, which challenges the fundamental scientific understanding of water's composition. Peterson argues against the conventional belief that water is a compound of hydrogen and oxygen, presenting a series of claims that question this long-held axiom.
One of Peterson's key arguments is the discrepancy in the behavior of water compared to its supposed constituents. He points out that water, a liquid at room temperature, doesn't exhibit characteristics consistent with a mixture of gaseous hydrogen and oxygen. For example, he questions how two gases at room temperature can form a liquid at the same temperature. He also challenges the process of electrolysis, suggesting that the gases produced during this process do not originate from water but from the decomposition of electrodes or electrolytes.
Furthermore, Peterson delves into the thermal properties of hydrogen and oxygen, highlighting how their boiling and freezing points are vastly different from water's. He also raises doubts about the ability to create water by combining hydrogen and oxygen, noting that no experiment has conclusively demonstrated this. Additionally, he questions the assumption that water can be split into hydrogen and oxygen, pointing out inconsistencies in the electrolysis process and the ratios of gases produced.
Peterson also explores historical and philosophical perspectives, citing figures like Mahatma Gandhi and Antoine Laurent Lavoisier to bolster his arguments. He challenges the notion that water's composition is a 'given' or an unchallengeable truth in science, urging a re-examination of what we accept as scientific fact.
Given your channel's focus on scientific exploration and debunking myths, a video testing these claims could be both enlightening and groundbreaking. Demonstrations revisiting the electrolysis of water, examining the thermal properties of hydrogen and oxygen, or even attempting to synthesize water from its supposed elements could provide valuable insights. This topic presents a unique opportunity to delve into a scientific inquiry that not only challenges conventional wisdom but also encourages critical thinking and a deeper understanding of the nature of water among your viewers.
Thank you for considering this intriguing and potentially paradigm-shifting topic. Your exploration of these claims could foster a fascinating and enlightening discussion.
Sounds like flat earth poppycock
What about micro plastics in the water?
Would lava rock or pumice stone do the same thi g as the green brick sponge?
Probably not as effectively. The green foam is basically a wick to draw water up to be evaporated more quickly.
Desalination is no problem to achieve with solar energy.
Sahara and other dessert areas could be irrigated and we would have possibility to turn desert into agricultural land.
Dessal makes salt excess concentration. Water from thin air is cheaper in energy but is lower amounts
Great topic, our world needs more people like yourself. Do you have any other simple desalination set ups posted such as simplistic diy filtration units from common materials that would serve a tiny seaside camp or houshold? Thank you Robert.🙂
Have a look at using a ceramic flower pot as water filter, the pores can filter out heavy contaminated water from what I've seen.
There are commercial versions available but they are quite expensive.
The pores will clog with the salt so a constant cost of new ceramic filters will need to replace the clogged ones driving up the cost/price of the water.
Like i stated a simple non glazed flower pot can be used which costs nothing, every filter requires maintenance/replacement.
It can possibly be cleaned out with some treatment. @@troywhite6039
The big issue with most forms of desalination is that you are still left with a large quantity of very salty water, if you put it back in the sea, you kill the ocean environment, QED you need to process a large amount of water and only convert a tiny fraction of it, removing water from the air, is the least environmentally damaging.
Salt has many uses globally, sell it for profit.
That Black Matrix Box At The End Of His Video, Is Probably The Key to Making A Solar Salt Water Box That Has Many Thin Levels Of Water. To Evaporate From, And Then Into A Cup 🍵 In England Theres Not Much Sun. But In A Dryer Climate Area, It Would Require A Video Of The Most Efficient and Effective Design. I Pay 1.76 A Gallon For Distilled Water ( No Salt ) and Go Through A a Gallon Every Two Days. 2-4-24
Lol, got to love MIT PR. like they are they only people working on, like, anything.
How about using a fresnel lens to heat the water to evaporation.
good idea
Thank you that's great tats for the paper on it I've been looking for this since I heard about it . Could you try to duplicate it ? Water personal water is a huge social security thing .your dead in days with out it .and if your laid up and cant pay they just cut you off . Thanks again🎉
You only need 1-3 gallons per person per day for drinking
Washing dishes, clothes and yourself in salt water is fine and toilets don't need special water. Disposal is what cost, sewage is anywhere from 15% to 70% to clean before returning the decontaminated water to nature.
@@troywhite6039 there's several things that are taken for granted and water is one .even with all the times whole populations are killed for lack of it . There's a social stupidity in humanity that thinks it's here and will never change. No you need personal water from the air . Not controlled by nature or governments. Next personal energy .next personal food then you might have a chance . Living on presumption will kill you .
sounds like something worthy of real research investment.
Huh. Doesn’t that seem sort of weird that after all the putzing around for decades… oh never mind. Fantastically fresh idea! I must still enthusiastically say.
The control pan should have something black of the same area in the water.
