Big Picture Science - Water the Chances

Water, water everywhere. But most of it is sea water – you can’t drink it. Discover the most promising technologies for desalination and why solar cells are key. Also, how astronauts filter “water-closet water” to drink it, and how to turn a salt pond back to a wetland.

Plus, from Roman aqueducts to modern-day pumps: a history of quenching human thirst. And, why NASA strives to “follow the water.”


You can listen to this and other episodes at, and be sure to check out Are We A Blog?, the companion blog to the radio show.
