A better use for The Shard?

The future of urban farming is under construction in Sweden as agricultural design firm Plantagon works to bring a 12-year-old vision to life: The city of Linköping will soon be home to a 17-story "vertical greenhouse."

The greenhouse will serve as a regenerating food bank, tackling urban sprawl while making the city self-sufficient. Plantagon predicts that growing these plants in the city will make food production less costly both for the environment and for consumers, a key shift as the world's population grows increasingly urban—80 percent of the world's residents will live in cities by 2050, the United Nations estimates. "Essentially, as urban sprawl and lack of land will demand solutions for how to grow industrial volumes in the middle of the city, solutions on this problem have to focus on high yield per ground area used, lack of water, energy, and air to house carbon dioxide," Plantagon CEO Hans Hassle says.



The greenhouse is a conical glass building that uses an internal "transportation helix" to carry potted vegetables around on conveyors. As plants travel around the helix, they rotate for maximum sun exposure. Hassle says the building will use less energy than a traditional greenhouse, take advantage of "spillage heat" energy companies cannot sell, digest waste to produce biogas and plant fertilizers, and decrease carbon dioxide emissions while eliminating the environmental costs of long-distance transportation. And growing plants in a controlled environment will decrease the amount of water, energy, and pesticides needed.
The greenhouse, which will open in late 2013, is already serving as a model for other cities—Plantagon hopes to install the transportation helix technology in regular office buildings around the world, eliminating the need to build entirely new structures. The tallest models even have a name: Plantascrapers.

Fake that

I did my first talk for one of the regular Sceptics in the Pub meetings at The Monarch pub in Camden on Monday night. I was talking about crime science and how changing perceptions can be a powerful weapon in solving problems. During one part of the talk I mentioned products that are specifically designed to 'trick' people. Here's a great example. They're called 'seat savers' and they're cast in soft vinyl. The idea is that you leave them on your seat at an event and no one swipes your place.

I don't know how well they sold but I assume not so well as the New York-based company that made them, called Jeremy's Place, seems to have vanished from the Internet. However, I did find another company called Fake Food Online who still appear to be trading. Here's the site.

Meanwhile, here's a similar idea. This one not only fools our senses but plays with our emotions too, most notably disgust. These 'Anti-Theft Lunch Bags' are pre-printed with what looks like green mould. The idea was developed by Sherwood Forlee and Mikoko Ouchi of the the. Design Agency as a tongue-in-cheek method of preventing co-workers or fellow college students helping themselves to your food. Interestingly, I've read reports that some people, even when shown that it's nothing more than fake, printed mould, still won't eat the sandwich afterwards. The initial impression of yuckiness is so strong that it effectively puts some people off. I guess it's that 'First bite is with the eyes' thing that makes Japanese chefs so extraordinarily careful about presentation.

Nasty eh? I include it for a reason. I'm working on a new book at the moment and one part of it talks about perception. I've interviewed some fascinating people so far and was lucky enough to spend some time chatting to comedian and musician Tim Minchin who had some very interesting stuff to say about 'magical thinking' and superstitious notions of tempting fate. One spin-off of this chat was that Tim introduced me to an old friend of his from Australia called Rob Schutze who trained as a psychotherapist specialising in helping people with Obsessive Compulsive Disorder. Rob has some great examples of when our mind seems to operate against us, like it's a separate entity. Did you know, for instance, that chewing gum doesn't lose a lot of flavour as we chew it? It loses some but what actually happens is that our minds get bored with it and effectively 'switch off' the taste. To prove it, try leaving a bit of 'tasteless' well-chewed gum (on the bedpost?) overnight and return to it in the morning; it will seem to have got quite a lot of its flavour back. You can get the same 'bored brain' effect by concentrating on another activity such as reading while eating. The food will 'lose' its flavour. But if you then stop reading, shut your eyes and concentrate on thinking about what you're tasting, the flavour will return. Chefs like Heston Blumenthal recognised this long ago and use sound and vision to do the opposite - to enhance the taste by making you concentrate more on the food. Famously, his 'Sound of the Sea' seafood dish looks like objects on a beach and you eat it while listening to a recording of crashing waves on a MP3 player concealed inside a seashell.

This brain/taste/perception thing is so powerful that if you melt a bar of chocolate in front of people, pour it into a mould shaped like a dog turd and then ask them to eat the resulting object many won't; the association is so strong. It's also why, here in the West, we don't eat insects even though many are very tasty; certainly no less tasty than the bugs we do eat like shellfish (I wrote about this at some length here). Fascinating stuff eh?
