Solvatten is a simple portable device which uses sunlight to purify water for drinking. It was invented by  [sv], and was intended mainly for domestic use in the developing world. Provided the sun is strong enough, it takes two to six hours to produce ten litres of drinking water.[1] It works through a combination of the natural ultra-violet radiation and heat (infra-red radiation) in sunlight, and also incorporates a filter mesh.[2]

The device is marketed by a company, Solvatten AB, founded in 2006.[1]

The device[]

The Solvatten device consists of two hinged parts which can open in the manner of a book, revealing two transparent plastic surfaces. Each half can hold five litres of water. When the device is placed in the sun, the plastic allows ultra-violet radiation to reach the water, which is also heated by the sunlight. It becomes safe to drink within two to six hours.[2] Use of the device can reduce the use of wood to boil water, thus acting to limit deforestation and carbon dioxide emissions.[2]

Reception[]

The device has received several awards:

  • 2009: World Wildlife Fund, "Climate Solver"[2]
  • 2011: , "Best Green New Product Innovation"[3]
  • 2011: , SACC New York-Deloitte Green Award[4]
  • 2013: The Energy Globe Award Mali[5]
  • 2013: Sveriges Ingenjörer, The Polhem Prize[6]
