Stanford Engineering Puzzle

March 2006

In last month's puzzle we somewhat fancifully illustrated one way that water could be recycled in future buildings. This month we show you another. Demonstrating and teaching resource conservation are key goals for the Stanford experimental green dorm project, which is being led by faculty and students in the Department of Civil and Environmental Engineering.

Directions for Puzzle:

This month your job is to route water coming from the utility in the bottom left to the shower. Then you will route it from the shower to the rooftop garden, where (after some on-site filtering) it could be used for irrigation. Rooftop gardens can help insulate a building as well as soak up rainwater.

Upon successful completion, a "secret word" will be revealed. For fun we will post (below) the names of ten alumni who successfully complete the puzzle and e-mail the secret word in the subject line to staff member David Orenstein. We'll post winning entry number 1, 11, 21, 31, 41, etc. up to 91.

You must have Flash installed to run this puzzle, which was designed by Scott Kim of Shufflebrain and programmed by Larry Doyle of Cyberiandesign.
