Same, I applied some nail polish when mine started crumbling and it has been able to hold it in place, but the hole is there already

Anyone please feel free to correct any misconceptions I might have had below, if you have more examples, let me know too:
Keep in mind that stuff like this is expected to vary a lot depending on design, temperatures, solar irradiance, humidity, shapes, water flow, wind speed, wind direction, drag, etc
Based on “Design integration of novel porous ceramic evaporative cooling systems”, their design had a water consumption ranging from 0.4 to 0.8 l/h/m² (liter per hour per square meter of surface area) (whereas predicted data from simulation was around 0.4 to 1.1 l/h)
For comparison, misting systems, which can be a popular technique to improve outdoor comfort in public spaces, might use around 0.8 l/h per misting nozzle
On another study, “Experimental study of cooling effects of a passive evaporative cooling wall constructed of porous ceramics with high water soaking-up ability” DOI, shows an evaporation rate of 20.7 kg/day for an area of 1.1m², converting to l/h/m², it is around 0.784 l/h, where it had max-min air temperatures at 36.4 and 26.2 °C, relative humidity (RH) at 72% and mean wind speed at 0.6 m/s
Another experimental study using porous ceramic water containers measured cooling capacity approaching 225 W/m² of exposed wet ceramic surface under hot and dry conditions (30–35°C air, 35–50% RH).
Computer modelling and experimental investigation of building integrated sub-wet bulb temperature evaporative cooling system DOI
A separate study, from the same author at different conditions, with air temperatures up to 45°C and RH up to 50%, found up to 280 W/m²:
Investigation of an Evaporative Cooler for Buildings in Hot and Dry Climates DOI
Considering latent heat of vaporization of water is about 675 Wh/kg at 30°C, it would give us an evaporation rate of around 0.333 and 0.415 l/h for the previous 2 studies respectively
If we consider that, on average, a healthy adult goes between 4-10 times per day to the toilet and that each time you flush, you can use between 4 to 22 liters of water depending on the efficiency of your toilet… yeah, I think we can agree we might have a bigger problem with water usage somewhere else
Summary of water usage below assuming the system is up 24 hours per day, which was not the case in all above examples
| — | Liters per 24h |
|---|---|
| Study 1 | 9.6 - 26.4 |
| Misting nozzle | 26.4 |
| 26-36 °C / RH 72% | 18.9 |
| 30-35 °C / RH 35-50% | 8 |
| 45 °C / RH 50% | 10 |
| Water efficient toilet | 16 - 40 |
| Old inefficient toilet | 88 - 220 |
So if you haven’t already, and if you can, change your toilet with more efficient option. Bonus points if you get a bidet
TLDR: You are more likely to waste more water going to the toilet than having a passive evaporative cooling wall


I might be wrong, but I remember seeing some numbers and your toilet would use more water than a similar system, so I still think it might be worth it (unless you use compost toilet with no water, then the comparison goes kaput). Let me try to find the source


Don’t leave us hanging, tell us more about your vision for the place, if you don’t mind. Is it a work in progress? What’s next on your to do list for it?
I make my own garam masala
Whatś in yours? I’ve seen quite a few different recipes, so just curious about yours


Did you only read the summary or the full report on Tesla? I linked 2 different pages so you can have your facts straight


I beg to differ, see Mozilla’s “Privacy Nightmare on Wheels” report for Tesla
In short: currently all options suck


I’d like to push back a little on your second paragraph, as most of the listed things mentioned can be remediated with appropriate planning/actions. Of course every case is a different one, this always depends on the local context, but as a general rule:
Trees are expensive to maintain
If you plant native trees, that usually isn’t a big problem, as they have been adapting themselves to those conditions for thousands of years
in addition to cracking sidewalks and roads
You can always select appropriate trees species that don’t have such aggressive root system that tends to crack them
they need water
Once again, native trees are your best bet, in conjunction with water harvesting techniques, I don’t think it will be a problem. I always recommend Brand Lancaster and Andrew Millison work on this subject. See Harvesting Rain Water for more details

the leaves need to be cleaned up
I always find this a weird obsession, why do we have to clean them up? In a forest, it usually lies on the floor and becomes nutrients, habitat, reduces water evaporation from the soil, protects the soil from erosion, etc
they need to be trimmed
This one depends a lot on the context, but at least around here, trimming usually means butchering trees and making them completely unbalanced, which makes the population even more upset as your point below becomes the likely scenario
they pose a liability risk so need to be covered by insurance
Healthy trees are not likely to cause problems. Again this one depends on how the city deals with it, but routine check ups should be more common
Considering all the benefits greenery has in our lives, I still think we come out way ahead with it in the long term, even if we were only looking at it from an economic perspective
Sounds cool. Did you DIY? Do you have to move often?
I don’t think pitch is a problem as those plants cling to trees at 90° and the layers are glued, but I understand it is not a solution that can be installed anywhere :)
I’ve seen green roofs on bus stops and favelas in Rio, Brazil, where their roofs have terrible infrastructure. From what I understood, they basically partnered with a local university to try to reduce the heat island effect in favelas, as most of them had no greenery at all
They came up with a cheap solution involving a plastic liner, similar (perhaps the same) to those used in ponds; a geotextile layer of bidim, which is a lightweight material; and plants that don’t need soil to grow, like those found growing on rocks or trunk of trees. Which means it is super light and still provide the same benefits as a green roof with soil in it


My house being a dome lacks a traditional roof for solar panels,
Can you solder? You could probably go that route if you don’t mind losing your round(?) dome aesthetics. I’ve seen some adaptations where regular rails were put in place and then additional supports soldered into the structure to lift it up and fit into irregular areas


Do it, and post updates to let us know how it goes :)

You can always prune them back too
