An energy-free charcoal cooler helps rural farmers keep fruits and vegetables fresh for weeks without electricity. It lowers temperature, reduces spoilage, and extends shelf life—tomatoes can last over 30 days instead of 4. Charcoal absorbs moisture and blocks heat, preventing drying and shrinkage. It works best in dry climates and is a simple, effective solution to reduce post-harvest losses.

@Abelvicent Wow. Nice. Didn't know this. Thanks for sharing.
@disisdeguey
Thanks so much as we , we believe more people would love to learn more about this, please help us boost, 🙏🙏 such that we can learn from each other
@Abelvicent Done. And also searching information about this. You have a great project there..greetings from Spain.
@Abelvicent ummm, charcoal coolers are simple evaporative coolers (you forgo to mention the water you need to rinse on this continuously).
They're pretty inefficient, because, surprise, using a black building material is not optimal for keeping a hut cold, and thus you need to sprinkle it with more what than you'd need for a better-suited building material. You just need something porous! It doesn't need to be, of all things, charcoal!
The << 1 °C reduction on temperature compared to outside:
@Abelvicent observed in https://csrl.cals.iastate.edu/files/inline-files/implementing_charcoal_coolers_to_reduce_post-harvest_losses.pdf , that's honestly a weak result.
Keeping your vegetables in the shade is better than in the tropic sun. *Any* box in the shade should do better than this at keeping temperatures closer to nighttime averages (open the box in evening, close in morning:contents colder than daytime air).
I'm very very doubtful of these "simple tech" wonders where neither the efficacy nor the actual resource usage (water can be more eff. used for cooling) is mentioned.

Thanks for breaking for me to know what am missing out
@funkylab
Thanks again thank 😌, the world 🌎🌍 requires, simple """togetherness"" and sharing ideas 💡💡💡💡 am great full that you observed it,,
@Abelvicent hm, is sharing bad ideas really what the world needs? You're in a unique position where you can research the things you share before you share them!
@funkylab
I can not be here, urging with,,, that's what works out in , where you leave, am free to share what works well for our community members,,,and l have ever done it practically,,,
I just left you to say what you wanted, next time think before you atour out something
@Abelvicent I'll surely continue to do so!
@funkylab That's good
