The Water Canary by Sonaar Luthra

tn_22084Just added from the TED collection this video presentation by Sonaar Luthra. After a crisis, how can we tell if water is safe to drink? Current tests are slow and complex, and the delay can be deadly, as in the cholera outbreak after Haiti’s earthquake in 2010. TED Fellow Sonaar Luthra previews his design for a simple tool that quickly tests water for safety — the Water Canary.
