As a class, our goal was to enter the LAGI (Land Art Generative Initiative) 2012 design competition as one entry.  Each student were to own and design a playground equipment that can harvest and utilize energy from the landfill underneath and/ or the kids that play on them.  Somehow, harness and convert the energy kids would exert at parks in the first place.  The site was located in Freshkills Park (the former Freshkills Landfill) in New York City. 

After some field research and observations, the playground equipment I found to be rich with potential and an ideal candidate was the popular swings.

Looking into wind-powered energy and technologies, it was natural to think about how the swing could capture the amount of airflow when in use. 

#1. Air pass thru vents.
#2. Air moves fan/ turbine.
#3. Turbine generates electricity!

Due to the size of the turbine and generator and the location, on a given day, a single set of  Wind Swing can generate enough electricity to power electrical devices (phone, tablet, computer, etc.).
