Smart people thinking about longevity.

Via Mediabistro we heard about an interesting advance in green design: long-lasting concrete. Engineers at MIT have identified the cause of “concrete creep,” which is essentially the degradation of the most frequently used building material on earth. Getting down to the nano level (some serious science speak going on there), they’re figuring out how to create concrete that can last hundreds of years instead of tens. That’s smart design.
