Cynthia Lam is only 17 years old but she is one of the 15 finalists for the Google Fair along with other inventions that aim to make the world a better place.
In the photocatalysis process, the water is purified and sterilized, producing hydrogen thanks to the division of the water and this can be used to generate electricity. For the process, only titanium is required as a catalyst and sunlight, but the production of hydrogen is low, which is solved with the addition of reducing agents, a function that some organic pollutants perform very well.
By combining the two mechanisms, energy production performance can be improved and the cost of generating hydrogen can be reduced while water purification is achieved efficiently. Similar methods have been proposed but require external power supplies so they cannot be used in remote locations.
via Teen creates a device that purifies water and generates energy at the same time – VeoVerde.
