We recently stumbled across an article about Phil Sadler, an Arizona native who put together greenhouses in Antarctica to grow food hydroponically for the US base there. His efforts in navigating the political maze to put together the right materials proved successful and he was successful.
Now he wants to take his talents to the other end of the world - the Arctic. There fresh food is notoriously hard, and expensive, to come by in the winter. The article notes restaurants paying more for shipping the food to their door than for the food itself and having to peel back frozen leaves on a head of lettuce until almost half of it was already gone.
Like vertical farms, growing underground in bunkers, and growing food in your own kitchen, this creative application of hydroponics is such a clear fit between problem and solution. It almost makes you wonder why it hasn't happened sooner... Keep going strong, Phil!
