Solar Bag Cleans Water While Walking

July 25th, 2012 by  


Clean water is hard to come by, but a solar-enhanced bag has combined portability and potability.

The Solar Bag, designed by Ryan Lynch and Marcus Triest, is exactly what it sounds like: an over-the-shoulder messenger style bag that can be filled with water and lugged around while the sun’s UV rays purify. The Solar Bag can decontaminate about 2.5 gallons of water in as little as six hours.

Lynch said the bag was designed to be used by families in sub-saharan Africa.

    Yeah, sure six hours of walking around, uhuh. May be worth drilling for water instead.

    How does the UV get to it if it’s black? Sounds more like solar pasteurization.

  • Ryan Lynch

    Its 2.5 gallons, not 2.5 liters
