Bruce Baikie and Marc Pomerleau are putting an earth-friendly spin on wireless networks.
Their nonprofit organization,
Green Wi-FI, is trying to bring Internet access to schools in developing countries via cheap, solar-powered Wi-Fi networks. The newly formed venture came out of a wish to which many parents can relate: showing their kids there's more to life than the daily grind of corporate politics.
The technical concept behind the Green Wi-Fi network is fairly simple. Each node in the network consists of a battery-powered router and a solar panel to charge the battery. The nodes are mounted on rooftops, and the network's Wi-Fi signals are transferred over a grid using a wireless network standard known as 802.11b/g.

Cornell researchers have created a broadband light amplifier on a silicon chip, a major breakthrough in the quest to create photonic microchips. In such microchips, beams of light traveling through microscopic waveguides will replace electric currents traveling through microscopic wires.
The amplifier uses a phenomenon known as four-wave mixing, in which a signal to be amplified is "pumped" by another light source inside a very narrow waveguide.

Funded by the European Commission, the Enabling Grids for E-sciencE (EGEE) project is the flagship Grid infrastructure project of the EU. The second two-year phase of the project started 1 April 2006 and includes:
[*]More than 90 partners in 32 countries, organised in 13 Federations
[*]A Grid infrastructure spanning almost 200 sites across 39 countries
[*]An infrastructure of over 20,000 CPU available to users 24 hours a day, 7 days a week
[*]About 5 Petabytes (5 million Gigabytes) of storage
[*]Sustained & regular workloads of 20K jobs/day
[*]Massive data transfers > 1.5 GB/s
