I remember talking with Phil Windley
about one of his ideas to leverage OnStar
as a distributed sensor network. He posited that all of these
cars tend to have temperature sensors, some form of GPS, and the
wireless communications … they could be used to create a nationwide
temperature map.

Now here is another article about taking this further to use cell
phones as the source of distributed sensor information. Very cool
idea. Everyone carrying the right kind of cell phone could opt-in
to providing sensor data to one or more servers. A huge variation
on SETI@Home!

Let’s see … what would someone pay me to participate in this? And protect my identity …

Scientists work to turn mobile phones into a distributed network
capable of measuring pollution levels — and possibly detecting
biological weapons before they can be launched. By Rachel Metz. [Wired News]
