If you are insanely interested in urban homesteading like I am, you must watch this! I had briefly read about the Dervaes family before, but seeing this video amazed me. Not only are they growing huge amounts of food on very little land (enough to feed themselves and sell a bunch to local chefs), you'll also see at about 5:30 in the video that they use very little electricity (solar powered), and bio-diesel (fry oil recycled from local restaurants). Off the grid, and growing their own food, all within a crowded urban environment. These are skills that will help us ease out of the cheap energy era. The more we know and learn from families like this, the better. Watch and be inspired!
