Clip: Season 5 Episode 1 | 7m 26sVideo has Closed Captions
A look into how photosynthesis is being used to harvest clean energy.
Scientists have used artificial photosynthesis to generate clean energy. This process typically requires electricity or natural gas but now researchers have developed a new device that's more than twice as efficient and runs only on water and sunlight. Zetian Mi, professor of Electrical Engineering and Computer Science joins Hari Sreenivasan via Google Hangout to discuss this breakthrough.
