"Carbon neutral" sounds pretty straightforward—simply remove as much carbon dioxide from the atmosphere as you put in. The trouble is, civilization began emitting CO2 when humans burned the first lump of coal about 4,000 years ago.
A great article in MIT's Technology Review got me thinking of something that's so obvious, but almost always subconscious: your mobile phone provider knows so much about you. Every time you make a call, send a text or download data, your provider knows who you were talking to and for how long, along with exactly where you were at the time of the connection, accurate to within a mile.
This staggering stream of data is a gold mine for the mobile operators--both from an academic and commercial perspective. Now, they just have to figure out how to make the most of it, answering complex privacy questions along the way.
SimCity players have struggled to keep their virtual towns alive against fires, tornadoes, and even UFOs, but can they handle strained water supplies and rising energy costs in CityOne? IBM's so-called "serious game" challenges urban planners to navigate the labyrinthine issues facing today's growing cities -- and perhaps to test better real-world policies.
