Researchers at University of Edinburgh and Italian National Research Council's ITAE research institute have developed a prototype solar powered fridge that can allow delivery of life saving vaccines to the remote areas of developing countries.
The researchers revealed that the system can generate up to 5kgs of ice every day and can store vaccines at 20 C to 80 C for up to three days, the minimum time set by World Health Organization.
The researchers hope that their project will lead to the development of a more compact and market-attractive prototype in the future.
"We are pleased by the results obtained so far on the proof-of-concept prototype. We are now seeking to develop a first generation commercial version which combines the solar thermal and adsorption based technologies", Dr Giulio Santori, of the University of Edinburgh, said.
