Designboom shows us just about the coolest vertical farm yet, by Studio Tjep. Actually, it is much more than a farm; it is a restaurant and amusement park as well. It is designed to educate as well as produce; "The entire process is visible to the visitor, giving the complex a didactic function as to new agricultural developments."
All food for the restaurant comes from the central structure and directly adjacent fields. Oogst 1000 combines extreme fun with extreme usefulness. One can see this amusement park as a huge people processor. Hotel guests are also the farmers, when you work, you can stay for free.
But the best thing about it are the pay toilets; since waste is a valuable resource, they pay you half a euro when you use them. Be sure to do the flyover video at Oogst.
