Here's an article I found interesting after having taken a studio based on biomimicry in my undergrad work:
It's about a hydropower generator inspired by the mouth of a basking shark. (Designed by an industrial designer!)
It's easy to understand the implications of nature's inspiration in the engineering world as nature often already beautifully does things we are seeking to do mechanically. The implications of biomimicry on architecture are still, for me, harder to understand. In our studio, at least, it was easy to initially turn to looking at ideas inspired by nature about buildings, mechanics that were sadly tack ons, or literal mimicry.
There's a biomimicry club at the GSD, now that I think about it. Maybe I should drop in.
