After the success of The High Line it seems like The City of New York is up to try and make some of the most out there public space and park projects happen. In this case it happens to be the LowLine(giving a nod to its above ground compatriot in Chelsea). An old warehouse in the Lower East Side is currently open to the public as a proof of concept for a new type of underground park and green space. The project has successfully raised over 100K on Kickstarter this year and has the support of many local officials and politicians. My favorite part of this idea and the project in general has to be the technology behind it. To create a naturally sun drenched park underground is of course by no means impossible, but it does take some serious engineering feats. Here they have utilized six tubes or collimators, which are controlled by a computer and GPS system to follow the movement of the sun and channel the greatest amount of light into the underground space during all times of the day. Once the light has made it below the surface and into the space it is reflected by a series of lenses and the anodized aluminum parabolic curve diffuses the light.
