Rochus Jacob designed this energy-harvesting rocking chair. It works by storing energy while you rock during the day, then lights up the attached OLED lamp at night. It is a neat concept, however there is no reason to wait for future technologies to build one. Just start with this human-powered fan design, add a small generator and a standard LED, grab your whittling project, and you should be set to go. [via gizmodo]
