Jonathan Walker, a high school student in Panama City, Florida, built a filter that turn cars’ carbon emissions into oxygen.
Walker, who has been praised by the U.S. Environmental Protection Agency (EPA) and the Yale University Science and Engineering Association, achieved a large reduction in pollutants in the first 30 tests he performed with his device.
He told The News Herald of Panama City that the average concentration of carbon dioxide fell from 14.6% to 3% with the use of the device.
There was an average of 0.49% oxygen, which rose to 12.65%, without the filter.
The young student told the newspaper that he was looking to create something that would not only mitigate emissions, but purify them to release something even better.
Vehicles are one of the largest contributors of greenhouse gases on the planet, which has been noted in this COVID-19 pandemic, with the global reduction, in the first half of 2020, of an average of 8 % of emissions of these pollutants due to quarantines compared to the previous year.
Walker said that he hopes to soon file a patent for the invention, which he considers to be highly viable.
The young inventor used PVC (polyvinyl chloride) tubing, rubber tubing (to store carbon emissions) and a dryer vent hose for the filter. He also used calcium, activated carbon and LED lights, among other elements, to transform the pollutant into oxygen.
The student explained that the “concept” is already proven and now the idea is to reduce the size of the device.
