l did bump into this when l visited Eco-Resource centre in Nairobi, Kenya. l got fascinated by the simplicity and its functionality. The simple piece of innovation so ideal for the preservation of vegetables and fruits in areas especially rural where there is no access to electricity.
Built with PVC pipes, corrugated zinc, wood, jute bag and water which serves coolant, a preservation system that can preserve fruits and vegetables for 2 weeks. lmagine how much harvest in the rural ares would be saved from waste when such simple innovation is being utilized.
l remember some years back when l worked in an agrarian community in Southeast Nigeria, l recollect visiting a local market which holds every four days and the amount of vegetables and fruits being wasted there is heart-rending. The locals bring their farm produce to the market, sell what they are able to sell, what is left over is heaped away as waste as it made no sense to them carrying the left-over back when there are still the same produce waiting in their farms for harvest for the next market day. The goats and pigs that roamed around the market looked so well-fed as the feed off from the farmers left-overs.
With such simple technology which can be constructed in homesteads with N5,000 ($30), Fruits and vegetables will have a longer shelf life.
