This is an amazing project undergoing development is Manhattan. The project aims to convert an abandoned underground subway station into a 1.5 acre park. How? By setting up parabolic mirrors above ground to catch sunlight, using fiber optic cable to transmit that sunlight underground, and similar parabolic domes underground to re-disperse the light again, providing lighting conditions adequate for photosynthesis to take place. Meaning plants could be grown underground and a 60+ years-abandoned trolley station could be converted into a beautiful recreational space! Here’s how the light would be transmitted:
And here’s how the park would look:
This is an awesome idea for a ton of reasons! A beautiful recreational space, reusing old space to create something new, and hopefully promoting interest in the environment! Definitely a project to keep an eye on!
