Solar cooling in developing countries
Vaccine saving lives.
Vaccines can be life saving and life changing. However most of them need to be kept not too hot and not too cold.
In a report, “Sustainable Energy for Developing Countries Report,” written for the Tear Fund, one of the primary needs identified for some of the world’s poorest communities (which do not have access to any electricity) is a device to keep medicines and vaccines at a safe temperature to ensure that they can be used. Such communities are often provided with medication free of charge by relief agencies but much is spoilt before use, as there is no means to maintain the items at the requisite temperature. Sometimes eutectic blocks like the ones you might take on a picnic are used during transport and they make the vaccine too cold and damage them. Other places just don’t have the electrical power to work a simple fridge to keep them from damage.
Solar cooling is able to provide an off grid solution. However the currently available ones are very expensive and unreliable lasting an average of only 17 months. Solar Polar’s cooling is simple low cost and very reliable.
Water as a basic human right.
Women in Africa and Asia have to walk five hours a day to collect 20kg water, wasting 40 billion working hours. 443 million school days are wasted because of sickness caused by unclean water. In conflict zones there is a terrible rate of attack during these trips.
In areas of high humidity, the Solar-Polar units can be used to condense water from the atmosphere, making a source of clean safe water close to villages (information from Water Aid).
