I had a great idea, certain to appeal to Albany Strollers and Rollers and satisfy the strict standards of Carbon Neutral Albany: By rearranging the community on a spiral path around a central water column we can make everything downhill from everything else! If your destination is above your current location, simply roll down to the bottom of the spiral, enter the water column through the airlock, float back up to the top, then roll down to your destination. Zero energy expended! As illustrated, most of us will bicycle within Plexiglas spheroids, but the system is a natural for scooters and skateboards, too. Pedestrians may find it a bit tedious, but I'm sure we are all willing to make some sacrifices toward the goal of a truly energy-independent and carbon-neutral community.
Some may object to this as a patently impossible perpetual-motion scheme. Others will want to get in on the ground floor of a once-in-a-lifetime investment opportunity. If you fall into the second group, contact me here on the Patch message board.
