A group of scientists at Massachusetts Institute of Expertise has successfully developed a brand spanking new expertise that can effectively turn water and sunlight in to energy. Yes, if this seems more like a dream, then have a glance at this effective yet cheap invention. World’s first practical artificial leaf has been unleashed by scientists at 21st National Meeting of American Chemical Society in Anaheim. This new invention can definitely become an approach for generating power from a less expensive source, thereby making it simpler for developing countries like India.
This high tech solar cell of a size of a credit card can power a house for a day. It’s been fabricated using silicon, electronics and various other catalysts that encourage chemical reaction within this small tool. The spurring of chemical reaction inside the leaf can make use of light to break water in to oxygen and hydrogen, further using it for producing electricity in a fuel cell. The main idea of the scientists was to generate an cheap tool that can basically be acquired by the developing countries for further advancement.
Earlier Works on Artificial Leaf
John Turner of United States National Renewable Energy Laboratory developed an artificial leaf, 10 years ago, but his invention was expensive. In addition to this, his artificial leaf was unstable and had a short lifespan of one day. However, this prototype developed by scientists at MIT is cheap, stable and can work for 45 hours continuously. Scientists have also affirmed that this artificial photosynthetic material is 10 times more efficient in carrying out photosynthesis than a actual leaf.
Statements by Person In Charge
Daniel Nocera, who leads the team of scientists at MIT, said that practical artificial leaf has been of the Holy Grails of science for plenty of years & he believes that they have done it. He added that placing these artificial leaves in a gallon of water & then placing in sun will permit this major invention to fulfill the basic electricity needs for a day of a relatives. Daniel Nocera also affirmed that their objective is to make each home its own power station. Now it can be expected that villages in India & Africa can purchase these affordable basic power systems & take maximum advantage of the new expertise.
To make this new expertise cheap, scientists configured a set of low-priced, common catalysts that included cobalt & nickel which helped them to make the job done in far less expense. In the work of research & analysis, it was found that these playing card sized leaves could work constantly for 45 hours without showing any drop in the output, but scientists are seeing forward to develop this photosynthetic material in a way that their efficiency & lifespan can be boosted even more.
