Ky has designed a closed-loop hydroponic farm system that centers around a bird feeder. Birds eat the feed and their byproducts fall in water that fertilizes plants including sunflowers (which provide a replenishment to the bird feed) and fruits and vegetables. Ky has a working prototype already yielding food in Hawaii, and also built one from scratch on the Semester-at-Sea ship. The system can be constructed entirely from biodegradable and recycled components, and construction and maintenance are simple. Ky and his team will be training economically-disadvantaged families in urban food desert settings to build and operate these systems, generating some diversity in their food supply through this sustainable and innovative technology.
