How To Build Cheap Water Heaters With Solar and Recycled Cans - The Life-Sized City - Buenos Aires

In this excerpt from the S03 episode in Buenos Aires of The Life-Sized City, Mikael visits the neighbourhood of Carlos Salas - 40 km from the city center - to meet Pablo from the NGO Sumando Energias.
Pablo shows Mikael how his NGO builds cheap and efficient water heaters using only cans, bottle and tetra briks. Providing the citizens of the low-income neighbourhood with hot water for the first time.
Some solutions are so simple and beautiful and have an immediate impact on the lives of our fellow citizens.
This system should be on the curriculum in schools everywhere, to show the students what is possible and how it helps the less fortunate citizens.

Underrated channel.

[@vaiyaktikasolarbeam1906]

this is so cool . I mean it works like the common solar heater but I never thought we can build that from our garbage

[@Seaninirish]

Fantastic idea! And so inspiring to see such an example of true solidarity! Thank you

[@VulpeX2Triumph]

Impressive!

[@swampdaley6088]

Outstanding!

[@Korina42]

Genius!

[@thewayiseeit2069]

As a ex plumber I’m worried about the bacteria that might be created in the storage of the holding tank of water doesn’t reach a very hot temperature.

[@Ponen77]

I guess they could run the usual cleaning routine that water holding tanks go through...like say chlorine bleach disinfection every 6 months

[@nevillenewman2785]

@@Ponen77 Plus, the water actually does get quite hot. Our condominium complex in California heated their big swimming pool with a system similar to this. Of course, in that setup, there was chlorine in the water already so any bacteria got a double-whammy.

the water is gonna boil fast, ever left hose on sun? actually it's nice school project but simple thinner black hose does the job too

[@onisetolordava5844]

I like everything simple too. thank you.

[@unmanaged]

great content... we have to get you some more subs! keep up the good work and I might just build one of these to heat a greenhouse.... :P

[@LifeSizedCity]

Let us know if you build one!!

[@simonbannow3905]

Imagine you learned such things at school

[@JLOFlix]

Very cool!

[@nevillenewman2785]

Why does the return to the tank only enter halfway up, rather than at the top of the tank? Is that just the way it works out, using no pumps and only convection to move the water? I would have expected them to run the pipe up another foot or two to the top of the tank, but I'm sure they have a very good reason to not do that.

[@stefgav]

Can anyone point me to how I can educate myself to build one of these?

[@mikeretz8747]

Pop can water heater

[@spencervance8484]

If someone wants to use hot water at night?

[@kevinrees3811]

what type of tubing did you use inside the heater

[@ktcadd]

It looks like green pipe, Tuboplus, good for hot water as far as I know. Not sure if it's available in the States, but we have it here in Mexico.

[@Silenceisconsent]

Be nice if that gave instructions

[@James-kv6kb]

The intros are just getting longer sick to death of this American crap

[@bigjim9640]

first lol
