Founded over 40 years ago by an economist, Practical Action's aim is to help impoverished people "use technology to challenge poverty", to gain "access to technical options and knowledge", and "influence the social, economic and institutional systems for innovation and use of technology." The "Downloads" tab has a link to "Practical Answers" that cover almost two dozen themes and lets users browse the extensive library, submit technical questions to expert, and it also provides users with a section entitled "Share" which documents peoples' experience with Practical Action. Visitors will also find the "Featured Articles" section of the Downloads useful and full of such practical information as "Build Your Own Tippy Tap", for hand washing after toileting and a "Solar Voltaic System Design Info Sheet" that covers electrical design issues. Back on the homepage, visitors will find links to their social networking, e-newsletter, and the latest from their series of blogs.
