Evaptainers is a Refrigerator that Runs on Sunlight and Water
Did you ever come-up with an idea that could help millions if not billions of people around the world? Neither did I. But an MIT student, Quang Truong, has come-up with something so unique and useful that it could benefit millions.
As you know, electricity costs in developing countries are through the roof. Farmers can’t store their goods in refrigerators and according to some stats, 470 million small farms are losing %15 of their overall income due to food spoilage. This had to change.
Spencer Taylor, Truong’s partner in crime says many NGO’s came to help these farmers and offered them refrigerators only to find out later, they have been using them as shelves. Obviously, a poor farmer can’t afford the cost of keeping a refrigerator, so what can be done to help?
This is where Evaptainers comes in, a refrigerator that doesn’t need electricity to run. You read it right, it does not require an electrical connection to work as it runs on water and sunlight. Hard to believe right?
The device looks similar to a cooler and draws heat outside of its interior and onto some highly conductive aluminum plates. These plates are connected with a special type of fabric, that is wet and should be kept wet to dissipate heat via evaporative cooling.
User will need to have six liters of water to keep things cool for 12 hours. Water shouldn’t be an issue because if someone is growing vegetables, he already have access to water, says Taylor.
This is an invention that can change the lives of millions of people and it’s cheap too. You can get it for just $10-$20.
