Africa’s Food Chain Value Addition: A Breakthrough in Solar Food Preservation

In this moving and transformative video, Professor Singer of Tharaka Invention Academy introduces a powerful grassroots innovation that addresses one of Africa’s most pressing agricultural challenges: post-harvest food loss. Set in the heart of Kenya, the story begins in a mango orchard, where fruit lies spoiled on the ground—wasted not for lack of abundance, but for lack of preservation and transport solutions.

With empathy and ingenuity, Professor Singer unveils a solar-powered food dehydration system made entirely from locally sourced materials. This simple yet revolutionary machine empowers farmers to dry and preserve perishable crops like mangoes, tomatoes, sukuma wiki, ginger, and more—extending shelf life by over a year without the need for electricity, refrigeration, or chemicals.

The video follows the process from harvest to preparation, slicing, drying, and final packaging—highlighting how this method retains nutritional value, reduces transport weight, and opens up new income streams for smallholder farmers. A single kilogram of dried mangoes, once valued at just 150 KES locally, can reach international markets at over 40,000 KES, showcasing the massive economic potential of local value addition.

Beyond technology, this video speaks to hope, resilience, and the return of a diasporan innovator committed to lifting African communities through education, invention, and training. Professor Singer also introduces his broader vision through Tharaka Invention Academy and its invention curriculum, designed to teach youth and adults how to innovate systematically—from dream to distribution.

This is more than a demonstration of food preservation—it’s a call to action for communities, governments, and partners to invest in sustainable agricultural technologies that uplift lives, reduce waste, and build economic independence. Watch now and be part of Africa’s journey from harvest loss to global impact.
