Like Jamie, Sarah, and Marc, I too find this a really innovative and worthwhile product. Living where I currently do, in a city that experiences extreme seasonal air pollution I am already extremely vigilant about checking monitoring stations and have a node in my apartment as well. The idea of being able to pool data on mass from contributing individuals has the potential to track trends and anticipate problems. As Jamie suggests, I would be more willing to invest in a technology that makes me feel like I am contributing to the greater good and making a difference. While this seems like something that could be added to existing mobile technology, the idea of putting this powerful yet simple tech device in the hands of ‘citizen scientists’ helps increase the appeal of an already very marketable item. The request for funding is quite clear and understandable – sign me up!
