When electricity is scarce, reliable cooling of medicine and vaccines poses a challenge.
Coolar turns the problem - heat - into the solution, by powering a refrigerator with 60°C hot water (i.e. from solar heat) instead of electricty!
It's the most reliable, sustainable & economical refrigerator.
What if reliable and sustainable cooling could be made available to everyone - improving basic health care and dietary options for people living off-grid - without the use of CO2-intensive generators or hazardous batteries and refrigerants?
