@annoyed707 if you have sunny days in the winter some could be harvested for heating at night.
Not much but every bit helps.
We are not looking for a single solution to solve this we need many options.
Think low carbon electric generation
Think heat pumps for moderate temps
Think thermal mass/ solar storage.
Better structure design.
We currently heat with propane I’d like to add a air source heat pump for the milder days and run propane on the cold ones.
But as always cost is an issue.

You didn't specify the energy density of the MOST fluid, so I found it for you. It's 396kJ/kg, which is 110Wh/kg. Lithium ion batteries are almost 3 times that.
Volumetric density is 359 kJ/L (100 Wh/L), compared to more than 730 Wh/L for Lithium ion batteries.

Maximum theoretical specific density is "966 kJ kg−1 = 268 W h kg−1 (unsubstituted norbornadiene)"
from the paper. I don't know if links are permitted. Anyway, they're using derivatives to increase the energy collection efficiency, and possibly stability, so you can have 3%, 18 years or 268 Wh/kg, not all at once.

The idea of using this to power headphones and mobile phones is ridiculous, "both" from the energy density, the flammability, the toxicity, the heat generation, and the fact you need a TEG or a Stirling engine generator in the device.

The chemistry is based on Norbornadiene-Quadricyclane photoisomerization.
Norbornadiene is flammable, Quadricyclane is flammable and toxic.

It might be useful as a way to extract/store energy from short wavelength sunlight (~300nm) as an addition to other technologies that doesn't perform well with those wavelengths. E.g. as a thin layer of fluid channels on top of solar cells. In that case it could probably cool the PV cells, increasing its efficiency. If it blocks too much of the useful light this would be useless of course.

@hyfy1970 Was the mentioned "oil" a literal "snake oil" or just a joke... The chemicals composition of the "body oil" of those winter resistant animals, should be analysed at melecular or atomic level... Thus, scientist will have an idea on how their blood, water fluid, etc- was able to prevent the scape of "heat energy" from their body- during the duration of the annual winter season... The blood & water chemistry of those dessert wild animals, should be also studied in great details- to know how their body withstand the super. hot environment of such dessert area...

The problem unfortunately with these "meta stable" isomers that are high energy, is there is a substantial decay rate generally speaking. I wouldn't be surprised if that "shipped liquid" had lost at least 3/4s of it's "high energy" isomer. High energy states aren't really that metastable if they were easy to get to, versus say a redox reaction like reducing CO2 to methane, where substantial energy is involved, any oxidation/energy release would be completely insignificant. This is just an isomerization, granted a pretty good one but easy come easy go, it's not as if we have carbons being reduced here. Redox reactions generally just release more energy too, if you put it on par with Lithium I'd say head to head good ol' Lithium batteries would probably outdo this in energy density, couldn't say by how much, but guesstimate 50%.
Even if the conversion is higher energy than I think, say extreme UV wavelengths, most of that energy is filtered out by our ozone layer. This would make sense to me if it's decay rate is reallllllly small.
This isn't a jug of gasoline you can use years later. Similar to a nuclear isotope (or evaporation of gasoline from a lackluster container) there will be decay, and likely very very significant. Anything to stabilize it will invariably lower efficiency further by pushing the envelope of bond breaking higher. Also.... catalysts are generally not cheap, what they are using really matters here (is it Nickel mesh on carbon? is it palladium?).
I always thought photo switching was a cool concept, but after a Master's on this shit, it's still too much of a gimmick for real world high energy processes. I know it seems Im shitting all over it...I kind of am....it does have some pretty neat applications, as a SWITCH...not as an energy medium.
You would likely have much higher efficiencies with concentrated solar simply heating a material engineered to have ungodly heat capacity, versus a single bond based conversion of isomers. Capturing photons is best left to large conjugated bonds or metals chelated complexes with lots of happy d orbital electrons to do the jumping states.

Something to consider is using different storage methods to their particular advantages. Like you mentioned, MOST could be paired with photovoltaics to harvest some of the heat of the panels. Sure it's not the most efficient for electricity generation, but we often use our electricity to generate heat. Skipping a few conversion processes makes it inherently more efficient, and there should also be a way to qualify the ability to capture waste energy from other processes.

I find the concept of light directly converted to chemical storage then converted straight to heat in a closed loop system very interesting. The conversion efficiency of light to doesn't need to be real high if you can collect for 8 months to get you through 4 months of heating during the winter especially since you would be collecting during the long days of summer to use during the short days of winter. Appropriate sizing of the system with long term storage would be easier also as you wouldn't have to over build your system in summer to insure enough in winter. I like the idea of having a 120 degree F heat source on winter days with a high of -10 degree F when even air - air heat pumps don't operate efficiently. It would be important to know life span expectancy of this system as I am disappointed in compressor life in heat pumps.

Long term storage absolutely is not going to happen; we are talking days at best. Norbornadiene is manufactured from acetylene and cyclopentadiene. Cyclopentadiene is obtained at a yield of 14 kg/ton during cracking of nafta. Acetylene is also an oil byproduct. When you crack hydrocarbons to get propane, ethylene and similar lighter fractions you also get some acetylene. That's two low volume oil byproducts that aren't made in any other way. The energy released when quadricyclane converts back to norbornadiene is 89 kJ/mol, and at 92 g/mol that's about 1 kJ/g (compared to e.g. 40 kJ/g for home heating oil).

The average amount of home heating oil in the US for the people who still use this as their primary heating energy source was 591 gallons/year (~2.0 tons/year) in 2021. Let's say only half of this is in winter and the other half is in summer when excess is available (heating requirements in summer are still significant due to hot water). So then you need 40 tons of this chemical; and to produce this you have to crack 2900 tons of nafta for each household that requires it, and nafta is only a part of all oil consumption. This is patently untenable since 2900 ton of oil equivalent is far more than a household uses in a lifetime.

This material is also not very nice to work with. The norbornadiene and quadricyclane are both flammable (flash point similar to pure alcohol; diesel, jet fuel and heating oil and similar are not flammable; they are combustible; you can easily put out a match in them because the flash point is much higher than room temperature so there are no flammable vapors above the liquid). Quadricyclane (the goal is 100% quadricyclane before you start to withdraw energy and convert it back to norbornadiene) is not stupidly toxic; but it's still pretty nasty. Hazard pictogram is a skull and cross bones, flammable sign and a dead fish (long term hazard to aquatic environment).

I like it! It sounds like a trade-off between efficiency and convenience/affordability. The fluid doesn't capture a large amount of solar energy, but the energy it does capture is rendered into a stable, portable form that can be piped around and used in countless different ways. I don't think anyone will be storing it for years when the sun will still be shining tomorrow, but there's definitely a case to be made for storing sunlight in the summer and using it in the winter.

Ryan Ballantyne

I'd be curious to know how this compares to the original chemical method for storing solar energy: photosynthesis. Years ago I read about a project that was growing algae in tubes that had CO2 bubbling through them. The CO2 came from electricity generation (ideally, a solid oxide fuel cell) that used the algae as feedstock in a semi-closed-loop system. It doesn't seem to have gone anywhere, so maybe it didn't really work? But it sounded promising at the time.

@Pete Venuti and yes, the example I just gave you is stated to go from colourless to coloured with heat not UV, opposite to what I told you. I don't know if this is new, or if my memory is failing me.
It does, however, seem to encompass charge redistribution as you were enquiring.

michael hart

@Pete Venuti We're probably of similar age.
As I've indicated, I'm really a chemist, not a physicist, but a female friend of my brother's wife used to enjoy telling me that her brother had Feynman as a PhD supervisor. That's as close as I got. :)

Pete Venuti

@michael hart yes , but I'm sure you know certain groups and motifs tend towards certain properties. I was just hoping if I could learn more about existing ones with interesting and relevant properties I might be able to make something with some similar characteristics. I'm just an amateur home chemist so for me to play with these things is akin to alchemy, but what the heck , if that's what I like to do with my time, right?

Pete Venuti

@michael hart "cold fusion" and muon catalysed fusion are technically two different but related things, as I understand it , 'cold fusion' is usually referred to as Crystal ~~lettuce~~ lattice confinement nowadays, amongst other things, and it's still good to get your perceived of as a leper, yes.
Chemistry using muons instead of electrons , or together with electrons , is definitely something I have never seen studied and only recently might even be possible with one of the high flux low speed muon generators being built. That would definitely be fascinating.
Yet it just occurred to me , in my dialogue with you, that maybe the Pauli exclusion principle doesn't apply to an electron/muon combination which suddenly gave me hope that muon catalyzed fusion might actually work!
I used to live by Brookhaven national Labs as a kid in the '70's/'80s, and had some interesting chats, I wouldn't have had to go far out of my way to have met Feynman and I regret not doing so...

michael hart

@Pete Venuti I don't really "know" of any. The particular one was for commercial purposes but text books work with simpler molecules. In principle you can tweak a molecule with an infinite number of variations.
Many enzymes do their fancy work using a transition metal, D block, element and transition metals are not really my strength either.

@tomas pecl 60c is fine if you are planning to use it for heating up your home with it. Imo thats about all this is good for. It might be able to heat up water warm enough for a shower but you would need a decent custom heat exchanger to get the water hot enough.
Actually i.dont think it would heat water well since most hot water tanks store water at 60°c as is. I don't see how a 60° fluid is going to heat water to 60°

@Daneel Olivaw rock conducts heat more than you might think. Stone houses are quite poorly insulated for this reason. I would think using rock to store heat wouldn't be great.

@Ouknow144 A catalyst is a material which helps chemical reactions to happen. It is enough that the chemical touches the catalyst and then the reaction will happen. You would not need light or heat or other energy to be supplied to the catalyst to work. Look up what is a catalyst.

This is cool because it is a new technological concept I haven’t seen before, rather than just a refinement of an existing concept. The isomer + catalyst approach is fundamentally different from producing a liquid fuel that requires later combustion (and needs careful handling from combustion dangers), or straight thermal storage. And because it’s liquid, it could theoretically be made in sunnier areas and shipped to less sunny areas, if the energy density makes shipping worthwhile.

What excites me the the most is the solar “rechargeable” fuel is tailored to a certain spectrum meaning if you make other molecules Tailored to the rest of the electromagnetic spectrum (and they don’t react negatively to each other) you may be able to mix different spectrum fluids together to get a ton of coverage. So stacking these different tailored fluids in the same receiver may be interesting.

You know I think theres a possibility to capture solar rays outside of our atmosphere instead of in our atmosphere, since theres more temperature variation in space because of the vaccum, the strength of sunrays aren't inhibited by our atmosphere.

jay armstrong

Interesting. The lower % of energy capture might be offset by the fact that it can heat your water, or that it functions as part of a battery with much longer lifespan than Lithium, for example.

Tony Su

For very, very long term storage the calculus probably moves from efficiency to total cost of ownership.
Efficiency wouuld be more critical to short term storage and use on demand, but if something is to be stored for... say 18 years, then efficiency would probably be the least important parameter of all.

Keiko Mushi

A few questions. How cost-effective and environmentally friendly is the catalyst? Also, how does the liquid react to cold conditions?

Marcel Poisot

2y↑8

This seems like a very promising idea, even if it only helps with heating (and not electricity in general). But so many questions remain. How much does the fluid cost? What is the energy storage density? What are the environmental risks (biodegradability, health impacts, side effects of production, corrosion of pipes, etc). I wonder how stable the fluid is. Is there potential for a fiery runaway reaction like with batteries? Would it really be cost effective to pipe or truck this stuff around, or would it need to be produced and used onsite, and thus only applicable to a niche target like food and beverage factories? I feel it could easily take another 10 years of intensive research to find a mix of chemicals to achieve reasonably wide band sunlight utilization and still meet all the other requirements. And that's if they're lucky.

jay armstrong

One way to find out 👍

Aurtisan Miner

This would be perfect technology for northern climates like Alaska and Canada. There is so much sunlight during the summer but almost none during the winter time. To be able to store that heat from the summer and use it in the winter would greatly reduce our energy costs.

fudgesauce

2y↑6

As mentioned in your video, the efficiency of the system depends critically on the max-min temperature differential. IIRC, the chemical goes through about a 60 deg C change when it encounters the catalyst, which means it is useful only for direct heat, like heating water or warming a house, not for electricity generation. The comment that it could be used to power headphones really says it all -- such applications are 0.0000001% of the energy budget. We need solutions for generation of GW levels of power, not mW levels of power.

David s.

Fredrik Larsson

2y↑12

This opens for something very important: the use of solar also in the parts of the world that only has sun enough during eight - nine months a year. But even more important is that you can compensate for the need of energy by using a lot of absorbing units. It gives the ability for the producer to adapt to the need for electricity rather than the limitations of the storage. In the long run, I dare say that's the key to economy because there price per unit will be possible to lower quite drastically in the end. We already have everything needed to absorb sunlight, it's the other end that's the problem. This should solve that problem.

soylentgreenb

That's the wrong conclusion. Concentrating Solar thermal is only suitable in the deserts that span about 15-30 degrees above and 15-30 degrees below the equator (at the equator is usually very wet and rainforest like climate and totally unsuitable). PV generates energy under suboptimal conditions; if it is 50% overcast you will get power as soon as the sun is not blocked; solar thermal requires continuous sun and generates essentially nothing if it is partially cloudy with a few minutes of sun and a few minutes without.

autohmae

I've been saying h2fuel also exists, an other liquid medium for hydrogen, You can fuel up your car with this liquid at the gas station.

7:36 - Whenever I hear that something mechanical is controlled by machine learning and AI, I'm skeptical of it. That's entirely marketing speak. Why is there a need to adjust things 30 times a second? The sun moves half an arcsecond in the sky in that time. What mechanical system is going to have that accuracy?

Also "While most systems usually" -> "this system is capable of" sounds like this system has not yet been optimised and so they're throwing around big numbers to make it sound impressive. The point of the current systems heating to ~500C is because that's the operating point for the working fluid (salt). They could heat up much higher than that if they weren't cooled by the working fluid.

They are non-toxic. The downside right now is that it's still in the lab. Low energy collected and recovered, but they're starting to try and scale that up. It'll be interesting to see how this progresses.

Michael Grubaugh

Using covalent bonds to store energy (as opposed to ionic bonds, which are used in batteries) would be much better at high density, long term storage. The ideas might be good, the tech might be hopeful, but I wouldn't invest money in the company.

Philosophy Man

FINALLY! Far too long have we been storing things as heat. As soon as I was a freshman in college when learning about energy stability curves i knew we could artificially spike it up to a high energy dip. Want it reversed? Find a way to make the origional state flow back/use it in completely different reactions. EZ money. Its exactly what pur body does with glucose.

Mike Lucido

Have always loved the way you present every article, but I have to say the tower power systems kill birds like crazy. I thought you might have added that piece of information.

James Early

MOST interesting! I’d like to learn more about their molecular gymnastics, and whether they would consider working with kinetic architecture modeling groups, etc?

Patrick Poe

I've been using technology similar to this for a long time, except the molecules have stored sunlight from eons ago. The downside is that it currently takes eons to close the cycle. We're in the process of upgrading to a shorter cycle regenerative system using a carbohydrate foam matrix. 😉

Mark Pukey

Very cool idea! And your recap added a lot of good perspective. Thanks.

So a 63 degree C temperature change is about 145 F for us Americans. Cycling that past a low speed fan would be plenty of heat for your home, and probably enough for most home water heaters. I can't wait to see this as a commercial product in a few years.

punkdigerati

Another thermochemical energy storage solution are salt hydrates. You add the heat to dehydrate them, where they can be stored stabily for long periods, then add water back where it generated heat exothermically.
The big hangup is that to do it efficiently you need really high temperatures, but that computer learning driven CSP might work.

Niclas Kårlin

The main story should be that enough energy was found from the sun in Gothenburg, since it's mostly cloudy :-)
But, great idea, I was thinking about storing the heat rather than electricity just the other day.

delayedlaughter

It resembles photosynthesis in some ways. Even if green costs more right now, consider the high value gained in energy security and personal power storage, portability, and use. Fusion would be nice , but isnt here yet.

Earl Otto

Thanks. Love innovation and those of you who are willing to share it. The best to you always innovators

Ollie Tower

Its an amazing concept because so much energy is lost through the transfer of solar into dc or ac energy while implementing these in systems would require only the transfer of heat (stored).

Wouldn't solar vacuum tubes be more efficient at producing heat?
BTW, this would make a great subject matter for a video, this tech is rarely mentioned.

Guy Tech

Solar Trough concentrator systems use the vacuum sealed tubes. The problem isn't the collection of solar energy its the working fluids that limit the efficiency. CSP systems just arent economical and several CSP companies ended up going bankrupt.

Chimel31

@C D Yeah, I am looking at them for winter next year (wood stove this year). €700-800 each panel though. I am renovating an old house and will add pipes for low temp floor heating, maybe wall heating too in some rooms, so these panels combined with an extra large tank could be perfect. Still running the maths on them, as I'd like to use these pipes for cooling too, maybe from the ice cold condensed water from the heat pump, and I'd like to use them for hot sanitary water too. When renovating, it seems that whatever you do, you need to "invent" everything. Not many people are specialized in low temp floor heating, for instance, even less use cellular glass floor insulation, etc.

@Mauro Rossi Not needed... Wave, hydro, and wind can easily power all the global needs as it is forever. Batteries will advance soon, he shows he here monthly as battery tech advances yearly now. The Solution Project Map details it, using good data

Harvesting ? for sure. Storing ? no way.
There is no viable economic solution at the moment, that store the energy we can capture during the summer in using during the winter. Just imagine this for 18 years!

fire2000k

Combining photovoltaics on a home's roof with thermal energy storage for home heating would boost the overall efficiency of solar for homes and industry. Maybe they will find a chemical that stores even more energy as it changes its molecular shape.

Shrapnel (Official)

Did I miss when they said how long they could pull energy? Was it instant discharge like a capacitor? Slow like a battery? How long did how big of amount made X watts and how long did X watts last?
I blindly ask this, I have not checked into it yet. I am going to read into this, sounds interesting enough to read at the very least.

Moosetick2002

Doesn't water or any liquid store heat (solar energy) infinitely long until they radiate it out? Or have solar energy powered pumps move water higher as energy storage? That can store the power for centuries if needed.

Alireza Akhavi

really amazing high quality videos thank you very much sir! :)

BW W

Love your videos! I always learn so much about the topics you cover.

Avi Cohen

Imagine a thermoelectric paint. It develops a voltage across itself, when exposed to sunlight.
You paint a conductive substrate, you paint a thermoelectric paint, you paint a conductive substrate collecting mesh.
You paint the two substrates, both bottom and mesh down to copper foil electrodes, and to a huge battery.
Every huge structure becomes a thermoelectric generator. Bridges, sky scrapers, marking lines on the side of the road, ....

George Galamba

In terms of long-term storage efficiency, how does this compare to green hydrogen?

Paul Pease

I live in MN. 16 hours of daylight in midsummer, while biggest single use of energy is heating in winter when there are barely 8 hours of sun. If this was efficient enough I would just use it to store solar energy and then use the heat released with a heat pump to replace my furnace.

pearcey77

I'd love to know more about MOST - how is it produced? What's the environmental footprint of producing a litre of it? What if something happens and it gets released into the environment? What does disposal/recycling of MOST look like?

fuelban

Very interesting as usual, fantastic subject. I think there's only better to come on this subject.. I've been working on HHo since 2006 and whilst a fascinating subject matter for guys like me, ( working in a shed) as it were.... I truly appreciate and believe hydrogen is our global answer to this energy dilemma we face..... Nice video....

BloodyIron

I feel like I'm watching an educational video on advanced technology the Human Race is researching in an online game of Stellaris. But it's an early game so we're still only on solar in various forms, and haven't finished researching Fusion tech. That comes in like 30 turns and we don't even have like space colony ships yet so we're still doing stuff slowly.

Boy do I love science!

Leonardo Rivera

Simple question: how do we know that the energy released comes from the solar or light exposure and not from a simple reaction from the catalyst and the yellow fluid? In other words, aren't we seeing just a chemical reaction that has nothing to do with the exposure to light? I don't think that was covered.

Ryan Gibbons

Possible and an under appreciated observation, but not likely in this arrangement. Light triggered molecular bond heat storage and release is promising.

That "Swedish liquid", sound's interesting in small niche applications, where its properties can be best exploited. But at 3% efficiency, compare it to using solar energy to make synthetic fuels, and see what the costs and efficiencies are.

John Sherwin

The Australian ZBM generation 3 solar battery seems to have standard chemical properties similar to this.
Fire retardant, full discharge, common chemicals, easily recycled, heat tolerant and unharmed by zero use.

Paul Brouyere

I’m quite convinced we all need to capture as much of solar heat we can get and store it in materials that can stand the heat. Only non toxic materials should be used for underground storage where leaks may occur. Earth is a good keeper of heat which can free this energy during winter. Low temperature but mass heating (like floors) during winter is best for small energy losses. You don’t need 18 years of storage. And of course insulation counts.

Luís Guerreiro

As solar power has its peak during daylight(when people are consuming more power), is it really that necessary to store solar power? I would think that renewables such as wind power, where the peak is not matched by the demand, would be more relevant in what concerns energy storage.

Joffrey Heyraud

Please note you can also use photovoltaic panels to charge a Li-Ion battery in Sweden and then ship it to China. This is a much more efficient way to transfer Swedish sunshine energy from Sweden to China (so far).

Christopher Smith

It's interesting. At first from the thumbnail I thought it might be a joke and the liquid was gasoline, or honey, but they hold energy longer. It ends up that it is still maybe a hydrocarbon?

Plants store solar energy from the sun. All you have to do is harvest parts of them, dry them out and then burn them when you need them. It keeps for thousands of years if left dry and away from ultraviolet light.

David Willims

i wonder can they combine the different methods and storage into one more powerful power source?

vijayan chomatil

How about having a solar thermal system for the purpose of desalination and storing power. The desalinated water creates brine which is stored in a way that it can retain a tremendous amount of heat for running a steam turbine for power.

mark5009mark5009

Since it hasn't been 18 years since they've started this adventure. How do they know it will hold that energy for 18 years? A lot can happen in 18 years especially in chemical compositions

The ability to store energy for longer time periods would work well in sunny northern locations, such as Alberta. Layering over existing solar installations and then transporting the high energy state fluid to cities would allow 16 hours of summer sunshine to heat homes during 16 hours of dark in January. Cool!

David Clark

@Roger Starkey Depends on what is cheaper.

Roger Starkey

@David Clark
I understand, but it doesn't make sense to store the energy in the fluid, then transport it to Edmonton. Send the electricity, then have the fluid in Edmonton.

David Clark

@Roger Starkey Southern AB has way more sunshine hours than Edmonton, and more room for large scale solar farms.

Roger Starkey

2y↑1

Why transport the fluid?
Use the heat locally and export the "raw" solar electricity now not used for heating via cables to be stored in the city.

Bill Angelos

Think about how great this could be to energize this liquid in northern africa or the middle east and piping it into Europe to be an oil or gas replacement, then piping it back (closed loop) so that it can be charged again. Could completely solve the energy problems in the EU and eliminate the need for batteries.

Methane "battery", BEAUTIFUL!.... I see NOTHING explosively wrong with this scenario! I wonder if increasing the surface-area of the atomic structure of this "energy storage" with some charcoal, potassium nitrate, and sulfur would increase the "yield"?.... I don't know... Maybe these experts should try it.

Greasyfingers60

As I am trying to relate to this MOST chemical storing heat, what I thought of is these crystal/solution heat packs that we use for hand warmers and neck warmers. I get it now. The warming packs are reusable by boiling until the solution is dissolved, and they release heat in an exothermic reaction initiated when you are ready to use them, by clicking a metal disc inside the pouch. I wonder how efficient a solar thermal concentrator would be that boils them. Heck, why not scale this up on a continuous process for large scale storage?

E bailey

My best guess is the future will contain a wide mixture of all these technologies. Molecular energy sounds like it will be part of that mix.

Does the absorption of solar energy have a cooling effect? If so that may be an added beneficial effect as it could help to prevent heat from entering a building, reducing the electrical cost of cooling.

Cold climate heating during winter for residential.
Here in Canada a large portion of our carbon release is for heating, a system like this that could harvest and store heat in the warm months for winter use would be great but as always cost will matter.

Someone else brought up, and I think it's a really good idea (could even be a central theme your channel, if you wanted it to), is doing some recap videos on past topics you've covered, which ones went big, which ones failed, and which ones are still progressing. I know you occasionally re-cover a topic, but a video covering a quick breakdown of various projects would be really interesting.

These early ideas RARELY scale up and become viable commercial products when cost, durability, etc. come into play. Great if this works, but just because something is being tested at a few watts in a lab doesn't mean it's "very promising" as a commercially viable / competitive energy product.

I love the idea of a single home dish style concentrated solar. Also, combining steam generator and water desalination.
Just imagine, a home with water catchment system where some is used as grey water (flushing toilets) and the rest is made potable by a solar still/ concentrated solar steam generator

Daniel

@Shpoople I don't know if it's really only "500 square feet", I'm not that fluent in freedom units, but you should stop assuming how houses are built around the world. The US is an anomaly, and houses with a 60/70 m^2 footprint are not uncommon here
Ask google for European town for a picture if it's too hard to imagine

Shpoople

@Daniel If your building is really "500 square feet" you aren't building any higher than 2 stories. That's the size of a large shed or a small house

Daniel

@Shpoople you know you are allowed to build higher than the ground floor, right?

@Daniel well if you can fit a family of four in 9 square meters, more power to you... But, not everyone lives in South Sudan...

@Nate B In case I misunderstood your OP, I meant that what you flush out the toilet is called black water. Did you mean using grey water to flush toilets (which is both the best solution and what people are already doing here and there)?
