After witnessing the effects that hurricanes can have and the mass floodings that hit the Eastern United States a few years ago, two teens invented a device that could help prevent future subway floods. The damage caused by floods was detrimental to the city, the subway system, and individuals who rely on public transportation. In order to find a solution, they came up with a system that uses a metal grate with a built-in, adjustable cover. So, when trains are running, one portion of the grate slides open to bring in fresh air, but when the system is shut down that portion can be slid shut to block the grate, preventing floodwater from seeping through.
Can you imagine the benefits of this mechanism in your city? Share the post!
