As a 7.0 magnitude earthquake strikes New Zealand, and millions of people are being displaced by the monsoon flooding in Pakistan, we are reminded of Mother Nature’s powerful force and our lack of control over her moods. However, today’s playlist presents lifesavers: three speakers who have found ingenious solutions to the consequences of disaster.

Some of these solutions are being used to help the flood victims of rural Pakistan, with the help of Jacqueline Novogratz of the Acumen Fund and TED’s Chris Anderson. Chris shares these stories on his own blog: http://tedchris.posterous.com/.

With his Lifesaver filter, Michael Pritchard demonstrates his solution to finding clean drinking water in desperate situations, in what appears to be a wine-into-water-type miracle.
