Farming using sea water

Imagine farming using sea water ! But this person is doing exactly that (link). Carl Hodges is growing salicornia, a crop nourished by ocean water that holds the potential to provide food and fuel to millions.
A few miles inland from the Sea of Cortez, amid cracked earth and mesquite and sun-bleached cactus, neat rows of emerald plants are sprouting from the desert floor. The crop is salicornia. It is nourished by seawater flowing from a man-made canal. And if you believe the American who is farming it, this incongruous swath of green has the potential to feed the world, fuel our vehicles and slow global warming.
The Earth's ice sheets are melting fast. Scientists predict that rising seas could swallow some low-lying areas, displacing millions of people. Hodges sees opportunity. Why not divert the flow inland to create wealth and jobs instead of catastrophe? He wants to channel the ocean into man-made "rivers" to nourish commercial aquaculture operations, mangrove forests and crops that produce food and fuel. This greening of desert coastlines, he said, could add millions of acres of productive farmland and sequester vast quantities of carbon dioxide, the primary culprit in global warming. Hodges contends that it could also neutralize sea-level rise, in part by using exhausted freshwater aquifers as gigantic natural storage tanks for ocean water.
