Keith talks with Wonyong Choi of Pohang University of Science & Technology in Pohang, South Korea. Wonyong tells us about his research into generating hydrogen from water using sunlight. The process called "artificial photosynthesis" is simply converting carbon dioxide to hydrocarbon. Wonyong also is looking into cleaning the environment using sunlight and photocatalysts.
