The Future Of Urban Farming?

I have this day dream where I play the lottery and win a huge jackpot. I take a big chunk of my winnings and build a large urban farm in Chicago. This urban farm, aside from giving me more space to play with plants, would serve as a teaching center for inner city kids and adults. I already know where it would go and can picture the buildings designed to look like farm houses and barns, the greenhouse, the fruit tree orchard, and nursery. My urban farm would produce organic produce and ornamentals for the community that surrounds it and create future generations of Chicago residents that are environmentally conscious. While I've been thinking about the use of land on a horizontal plane some forward thinking architects have been thinking vertically.
