Pot-in-pot refrigeration without electricity

Posted by steve on September 6, 2004

As IFTSP has maintained, going forward to a sustainable future requires applicaition of what we know, and sustainability promoting inventions are often simple and quickly taken up. Take the ROLEX-award winning pot-in-pot invention by Mohammed Bah Abba. Separated by a layer of constantly wet sand, the evaporating effect cools the inner pot.

Food spoilage is radically reduced, farmers can now sell their wares over longer periods, eppplants lasts for 27 days, and African spinach for 12. Based on simple technology and local materials, the invention helps bolster the local economy of rural areas.

Sustainability Circles revisited

Method notes

I reviewed the script from the circle exercise and realised the instructions were far richer in detail than I had first realised. (See below.)

Conclusion. Always review tapescripts and document the invention in pictures and other ways (reports etc).
