  • German engineering goes green with a fog-collecting system that serves the water needs of an arid Peruvian village.

    Biologists Kai Tiedemann and Anne Lummerich are finding ingenious ways to help people living in arid regions find and develop new sources of water. Bellavista, a small, hillside settlement near Lima, Peru that is unconnected to the municipal water supply is enveloped in fog through most of the winter. There, the pair designed a fog-catching system that captures and collects fog-water for use by the local population. Built in 2006 by members of the community, the system delivers hundreds of gallons a day to its resevoir during the foggy winter months.

But there’s another, lesser-known dimension to this......read more

A bite of an orange is endless summer. Now, in this scariest of seasons, California is also where our nightmares collect. At the moment, the largest fire in the......read more
