Taiwan's version of a "super toilet," which uses even less water for flushing than regular water-saving toilets, will hit U.S. stores early next year.

The super toilet developed by Chen Wei-lung, an assistant professor at Chaoyang University of Technology's Department of Industrial Design, with help from the local industry, can flush 99 percent of 100 resin balls with only four liters of water during tests. The industry standard is 95 percent flushing efficiency.

Regular toilets use nine liters of water for flushing.

Taipeitimes.com quoted Chen as saying that the super toilet will be mass produced in China. The product will not be sold in Taiwan due to a limited market and its higher price than local toilets.
