Hackers set sail to save the world

When you combine one boat with 26 hackers and 100 days at sea, what do you get?

The voyagers hope it adds up to real-world solutions for the globe's most pressing issues -- from climate change to poverty.

Unreasonable At Sea, a new program aimed at creating technology to solve big problems, will put 11 teams of hackers, scientists and entrepreneurs from 16 countries onto a ship in January to see what bright minds in a confined space can come up with. The teams include a water purification startup, a company that is developing technology to give sight to the blind, a group that makes digitally programmable and rechargeable hearing aids, and a company building affordable and fuel-efficient stoves.
