Any connoisseur of mechanical wonders should follow the blog over at The Long Now Foundation. Here is an excerpted post from their blog:
Early on in the Clock project we saw that of all the modern timepiece companies few were doing truly new things. One of the rare exceptions was Ulysse Nardin. Once we completed the first Clock prototype in fact we hosted Ludwig Oechslin their chief design innovator for several months here in San Francisco to evaluate our Clock which was very instructive.
Long Now member and alumni Camille Davila sent me a note about a recent development at Ulysse Nardin, a cell phone that is charged by an offset weight swinging around from the ambient motion of the owner. This is an adaptation from mechanical self winding watch technology of course, but it is very cool to see it crossing over into other personal electronics. You can see more on this on their website here.
