Green Wifi "seeks to bridge the last mile internet access with nothing more than a single broadband internet connection, rooftops and the sun".

Mesh WiFi is a network technology and topology in which each user is also an wireless access point, moving signals to and from neighboring users to create a wireless network (the 'mesh') without a separate wireless infrastructure.

OLPC is an MIT/UN initiative to develop a $100, 2-watt laptop powered by foot pedal or hand crank. Wired 4/06
