This is really cool. This is an example of how technology, properly diffused, can help us figure out ways to live more sustainably.
I really hope my mechanical engineering friend Seth posts a comment on this thread that points us in the direction of his ongoing work involving the design of buildings and urban areas to be more in accord with environmental processes. His work involves finding ways to measure both the indoor environments of multi-storied buildings and the local environments created as a result of urban infrastructure.
Seth: I encourage you to read this as a gauntlet thrown.
