A bicycle-powered, Linux-based VoIP system: not your usual high-tech architecture. But what if you were one of the more than 1 billion people living without electricity? No power, no phone. The mission of Inveneo, a nonprofit group of inveterate high-tech adventurers, is to bring developing communities that never reached a 20th century level of infrastructure into the 21st century. Its bicycle-powered system brings not just VoIP but also e-mail and Web browsing to remote areas.
