Well here's one of those feel good green designs that would never work because of its complete lack of real-world practicality: it's the cork tent. Called the Tree House and designed by Ana Correia, Vasco Lopes, Vera Gomes and Bruno Guerreiro for Dideia, the design uses cork for its insulating, natural and lightweight properties. Hop inside and be protected like a 50-year-old bottle of fine wine.
While it looks about like the size of a beer keg, it has the ability to roll up into a handy carrying case so that you can easily get it from the car to the campsite. Maybe I'm not all that well-versed in cork, but from what I've seen, it's not exactly the most durable, flexible material. Seems like this tent would crack and splinter every time that you roll it up--if not before hand while it's pitched at the campsite.
And is cork even waterproof? It always seems like it absorbs wine. Waterproofing is kind of important when it comes to the tent. In fact, it's kinda the whole idea.
I don't think I'll be trading in my no-see-um and rip-stop for cork anytime soon, but I'd love to see one of my buddies in one of these. Preferably, next to a big hill. Looks like it could really get tumbling.
