Our planet is experiencing an increase in the temperature with each passing day. So, the devices that can keep your dwelling cool are much in demand. But not everyone can afford these luxurious items. For those unprivileged ones here is an ingenious cooler that can be made at home using scrap materials and even trash. The Solar Cooler in a Can is a project to beat the sweltering heat simply by adding water.
Based on the recent invention of Emily Cummins, originally designed for impoverished families in Africa to keep meat and milk from going bad, this evaporation fridge comprises of an inner and outer tube, with a wet material in between the two layers. The inner tube holds perishable items in a sealed container. The wet material between the two tubes contains water, which on evaporation removes heat from the inner tube and lowers the temperature.
To build this portable cooler, all you would require is an old paint bucket, an empty lantern propane tank, 2 plastic tank caps, 4-6 rags/washcloths and 2 mesh gutter covers. Doesn’t it sound interesting to make a cooler yourself, that too one which is safe for the environment? Simply collect the items from the scrape lying in your house and follow the instructables.
