Electrolysis device to replenish oxygen in Lake Biwa

OTSU, Japan - Researchers from Lake Biwa Environmental Research Institute and Shinshu University have jointly developed a deep-water electrolysis device (photo) to replenish oxygen at deep-water locations in Lake Biwa and began an experiment at the lake on July 18. Electricity to power the electrolysis device is supplied by solar batteries installed in a vessel on the lake. The oxygen density in a water tank that was sunk to the bottom of Lake Biwa rose from 0.4 milligram to 6 milligrams 90 minutes after the electrolysis device inside the tank was activated. Michio Kumagai, a senior researcher at the institute, says that density of oxygen is ''totally enough'' to sustain living organisms. Researchers say they plan to tap the hydrogen produced in the electrolysis process for use as energy.
