SolarSack
Abstract
SolarSack is a water container that uses the sun to kill bacteria and virus in water, making it safe to drink.
SolarSack combines a clever design, with the right material, resulting in a retail price of only 2€. With a Solarsack, you can purify 4 liters of water in 4 hours, and it can be reused over 150 times, providing over 600 liters of water.
SolarSack is a good investment, both for the customers and the planet, as it is 10 times cheaper than boiling with charcoal, and 20 times less of a strain on the environment, per liter of purified water.
