Artificial Leaf - New Economical Photosynthetic Invention



A team of scientists at the Massachusetts Institute of Technology has successfully developed new technology that can efficiently convert water and sunlight into energy. Yes, if it seems like a dream, then look at this cost effective invention. The world's first practical artificial leaf initiated scientists 21st National Meeting of the American Chemical Society in Anaheim. This new invention surely can get access to generate power from cheaper sources, thereby making it easier for developing countries like India.

This advanced solar cell the size of a credit card can power a house for one day. It is manufactured using silicon, electronics and various other catalysts that promote chemical reactions in this small uređaj.Potiče chemical reactions within the light sheet can be used to break water into oxygen and hydrogen, is still used to produce electricity in a fuel ćelije.Osnovna idea of scientists was to create an inexpensive device that can be easily acquired in developing countries to make further progress.

previous work on artificial leaf

John Turner United States National Renewable Energy Laboratory has developed an artificial leaf, ten years ago, but his invention was quite expensive. In addition, its synthetic sheet is unstable and has a short lifetime of 1 day. However, this prototype by scientists at MIT is an inexpensive, stable and can operate continuously for 45 hours. Scientists have also confirmed that this is an artificial photosynthetic material is ten times more effective in carrying out photosynthesis, the actual list.

statement by the person

Daniel Nocera, who leads a team of scientists at MIT, said that the practice of artificial leaf was one of the Holy Grails of science for decades, and he believes they did. He added that the setting up of artificial leaves in a gallon of water, then placed in the sun will allow this great invention to meet basic electricity needs for a family day. Daniel Nocera has also confirmed that their aim is that each home to its power. Now you can expect to villages in India and Africa can I buy these affordable basic energy systems and to take maximum advantage of new technologies.

To make these new technologies cost effective, scientists have identified a number of inexpensive, common catalysts involving cobalt and nickel, which helped them to get the job done at far less cost. During the research and analysis, it was found that the game card sized leaves can work continuously for 45 hours without showing any decline in production, but scientists are looking forward to developing this photosynthetic material in a way that their efficiency and life span can be boosted even more.
