Conventional wisdom indicates that salt water, while looking refreshing, offers no source of adequate hydration. Thus, crops could never hope to be grown in the stuff. However, a group of researchers in the Netherlands just proved that conventional wisdom wrong by creating a salt potato. 

The potatoes were grown using a steady diet of salt water under exacting conditions. The result? A sweet and slightly salty potato that tastes, and smells, unlike any other spud out there. Also, they just might make a French fry that doesn't need extra salt.

The big news here is that the researchers suggest this same process could be used to grow other crops using salty sea water. There has been no word if the reverse will prove to be true. In other words, the world still waits for fresh-water-weed.
