Aside from Sony's battery powered by shredded paper, there were plenty of quirky products and ideas on display at the recent Eco-Products 2011 in Tokyo.
Fumitate Matsuoka from Tokyo-based Kurumaya, one of the few rickshaw makers left in Japan, poses with the latest model. It has a lightweight aluminum frame and a design featuring the new Tokyo Sky Tree, a tower that opens in 2012. It seats three and carries a price tag of 2,100,000 yen ($26,900).

Taiwan's Wellypower Optronics was showing off its Princess Series cold-cathode-fluorescent lamp bulbs, which promise a more natural lighting color. The company is pitching them as essential cosmetics accessories during makeup application.
