NEW YORK: Scientists in there search for a sustainable renewable energy source have eventually created an unique “bionic leaf” – a leaf that uses sunlight to produce liquid fuel!
The innovative work carried by a team of scientists from the Harvard University said that their new discovery, dubbed as ‘Bionic leaf 2.0′ uses the natural solar energy to split water molecules into oxygen and hydrogen, and hydrogen-eating bacteria to produce liquid fuels from CO2.
One of the scientists said that the new system can convert the solar energy into biomass with about ten percent efficiency, higher than the fast growing plants in which the photosynthetic efficiency is only one percent.
Daniel Nocera, the Professor of Energy at Harvard University said, “We have developed a true artificial Photosynthesis System. It is not a new dimension, before this people were using artificial photosynthesis for water-splitting but this is a true A to Z system and we have done well in enhancing the efficiency of Photosynthesis”.
According to the scientists, the system can be used to generate usable fuels for various purposes and its uses can be doubled if the principles are applied to develop a particular fuel.
“In Principle, we have the capability and the platform to make any carbon-based molecule. So this has the potential to be incredibly versatile”, said Pamela Silver, the Professor of Biochemistry and Systems Biology.
“We have developed a process which is much better than the actual photosynthesis. We are determined to develop it in a such a way that it is also applicable for commercial technological needs. Our artificial leaf system fulfills the promise in many ways as it uses Solar power to split water and make hydrogen fuel”, she added.
