Scientists create stem cells for CO2 capture and conversion of solar energy fed
A team of scientists at Princeton University in the United States, in partnership with a starup in New Jersey, the Liquid Light Inc, created an electromechanical cell capable of transforming a combination of carbon dioxide (CO2) and water in formic acid, using solar energy to a local supplier of electricity.These cells used to convert CO2 are made of channels that contain liquid, which in turn is surrounded by metal plates the size of rectangular Lunchbox, and are constructed from parts of easy attainment.The researchers used a process called matching impedance to balance the power generated by the solar panel with the amount of energy that the cell could deal, in order to create an optimal efficiency for the system.Such a process has an energy efficiency of 2% through the superimposition of three cells together â€" totaling twice the efficiency of natural photosynthesis and the best energy efficiency of a device created by man. The process is similar to artificial photosynthesis system developed by Panasonic, but with a 10 times greater efficiency, referred to Inhabitat.The product of the process, the formic acid is found naturally in the Ant poison and is currently used as a preservative, antibacterial agent for animal feed and for the production of a salt used to thaw the runways of airports. In addition, the formic acid also has the potential to store energy inside the fuel cells that produce.Foto: Juan Antonio Capó / Creative Commons
