These people are brilliant. Necessity really is the mother of invention!

Instead of the hand, use a brick for measurement between a container or crate. That's what we do in our village for this evaporative refrigeration. Its quite ancient and works well in villages that has power outages quite often.

I really liked hearing the presenter speak her native language, because usually whenever I watch anything with African people they're speaking in English. This was a very inspiring video. I really liked how they used inexpensive and innovative ways to help their people. I also really liked seeing Africans helping other Africans

I love to hear Swahili it is such a sweet sounding language.

A nice, simple technology using locally available materials, simple know-how, and not labor-intensive! I am amazed! The small farmers are able to preserve their vegetables and still make them marketable!

I love your dedication to make such a beautiful thing and to help farmers.

Thankyou for this it was easy to understand and I am sure my husband and I could manage to do it even in our 70s. We live in Australia where it can be very hot and I am worried that the electricity will cease to exist so I am reasearching ways to keep our food cool. This way beats everything else I have seen so thankyou for this wonderful idea
