The Hestia Project

I enjoy reading up on science and one of the web sites I check daily is Today I ran across an article on The Hestia Project an effort by researchers at Arizona State University and Purdue University to create a city-wide CO2 emission visualization system. Pretty impressive they model CO2 fluctuations hour by hour and building by building.
