IN SHORT
HELLA
BOCCARA
FOUNDATION
Development of target group-adaptable products and services, to promote decentralized systems for energy, food, water and medicinal plants by using the only freely available energy source, the sun.
WHAT YOU SHOULD KNOW
ABOUT THE FOUNDATION
The Hella Boccara Foundation has the goal to improve the quality of life in the Global South by helping to reduce the prosperity gap between the Global North and the Global South. With its own projects and developments, the Foundation enables the creation of autonomous and sustainable structures that use solar energy as an energy source, based on decentralized, low-threshold and efficient technologies.
Solar energy is the largest and most reliable source of energy in the Global South. Combined with appropriate storage technologies it is always available, clean and free of charge. This reduces dependencies of non-regenerative sources of energy and makes them obsolete step by step. Thus, economic independence and prosperity are strengthened and emissions responsible for the global climate change are avoided.
To accomplish its goals, the Hella Boccara Foundation coordinates the transfer of technologies based on solar energy to the Global South through its Transfer, Technology and Training Centers (TTT Centers).
-
To convert the sun's radiation directly or indirectly into all required forms of energy
-
to store energy in a sustainable and efficient way
-
to create energy-adaptive micro environments (microclimate zones).
-
to promote self-regulating systems for the production of food and medicinal plants
CLEAN
PHOTON
“Clean Photon” is a system for disinfecting bacterially contaminated water using sunlight and photocatalytic materials. Unlike conventional methods, it works with a broad spectrum of light to rapidly destroy bacteria, viruses, and other microorganisms.
The system consists of a flat water container where a photocatalyst activated by light generates free radicals that eliminate pollutants, offering a simple and less weather-dependent solution to water purification.
SOLAR CABINET
DRYER
The SCD (Solar Cabinet Dryer) is an indirect, double-pass solar dryer.
Air is heated through a flat-plate solar collector and recirculated over the food trays inside a sealed chamber at temperatures between 45 and 60°C, ensuring that the product is never exposed to direct sunlight.
Most of the heat is transferred to the food in the form of infrared radiation from the underside of the absorber plate, providing a heat transfer rate 4 to 6 times greater than that achieved through convection alone.
This process enables rapid and uniform drying without the risk of scorching or nutritional degradation of the product.
A programmable fan maintains stable temperature and humidity levels throughout the drying cycle, extracting hot, moisture-laden air through the base of the unit.
The sealed chamber protects the food from insects, dust, and other sources of contamination, eliminating the main risks associated with open-sun drying.
The system features a modular design and incorporates an electronic module powered by solar photovoltaic energy, allowing it to operate even in locations where electricity supply is unreliable or unavailable.
This solution is already being used by community groups in Guinea-Bissau, where SCD dryers help preserve food by extending its shelf life from 2 days to up to 6 months, reducing post-harvest losses—which can reach 60% in these regions—and creating opportunities for local income generation and new employment.
TECHNOLOGY, TRAINING & TRANSFER
The technologies promoted by the Hella Boccara Foundation can be freely combined and allow for complete autonomous villages, ecologic greenhouses and other systems. These will be built and maintained locally, thus creating stable jobs. Demonstrations and trainings will be provided at the Technology, Training and Transfer Centers (TTT). The TTT-Centers will work interested people, and transfer the necessary knowledge and training during courses, both in practice and theory.
