One of the big criticisms that's been leveled at the much-vaunted OLPC
project is that it's missing one key element: internet access. Well, a pair of Sun Microsystems employees are looking to remedy that situation with the Green WiFi project, which promises to bring cheap, solar-powered WiFi to developing countries. The project's modeled on MIT's Roofnet wireless mesh network project (and isn't the only one, either
), but takes things one step further by making each node solar powered, meaning that the network could be extended virtually anywhere. They've also taken care of the other big hurdle: price, using off-the-shelf gear and open source software to keep the nodes down to no more than $200 each. Although still in the prototype stage, the team says they're going to start deploying their first grid network in India later this summer, PVC or not.
