"With ground space of 10,000 square metres (107, 640 square feet), a vertical greenhouse represents the equivalent of 100,000 square metres of cultivated land" thanks to the rotating spiral that allows continual planting.

"An inventor came up with the idea 20 years ago but none of the people he presented it to believed in it. He presented it to me 10 years ago and it seemed like a good idea, so I talked to Sweco, a Swedish engineering firm, and they agreed to build these vertical greenhouses," Hassle explained.

1. Plenty n/t

2. Does the thing tilt on an axis to follow the sun? That would be cooler, still! nt

3. That'd be a hell of a mess, you silly.

And all the plants would grow screwy from vertigo.

4. Well, not on a steep angle--a slight one, so that the rays would be maximized! nt

5. I was kidding.

It's not too far-fetched, though the cost would be prohibitive. However, the people of Havana, Cuba grow most of their food within the city and sell the excess on the streets.

Those crazy commies!
