What is 10' tall, has six hydraulic legs, and is powered by the wind and solar panels? The prototype pod house built by art collective N55 in Copenhagen, Denmark. With the help of MIT, N55 built the pod over a two-year period at a cost of £30,000. Designers say it provides a solution to the problem of rising water levels as the house can simply walk away from floods. One of the designers says, "This house is not just for travellers but also for anyone interested in a more general way of nomadic living." It won't be long now until the Japanese make Howl's Moving Castle.
