I came across this enigmatic construction sign yesterday on the side of the West Side Highway in Manhattan. I did a double-take, trying to determine if, perhaps, I was the only one who could see this message.
What do you see? I honestly can't think of a reasonable explanation...
The opening keynote speaker at the Towards Carfree Cities conference is Mia Birk, from a bike/ped planning firm here in Portland called Alta Design. Check out the short episode of "Big Ideas for a Small Planet," above, featuring Mia talking about the pedestrian & bicycle planning movement in Portland -- she's very eloquent and the makes the argument for bike- and pedestrian-friendly cities in a very accessible way.

I've heard this story in various forms over the past few years, but according to the London Times, pedestrian power is ready to be harnessed:
Underfloor generators, powered by “heel strike” and designed by British engineers, may soon be installed in supermarkets and railway stations. The technology could use the footsteps of pedestrians to power thousands of lightbulbs at shopping centres. It works by using the pressure of feet on the floor to compress pads underneath, driving fluid through mini-turbines that then generate electricity, which is stored in a battery.
Apparently, this technology can also be used to harness power from anything that regularly moves due to environmental factors: train & car bridges, antennas, buildings, etc. Photo: Preshaa on Flickr, who is also working on turning this graphic into a t-shirt.
