On May 5, freshmen from MIT’s Terrascope learning community presented a variety of technologies for reducing global energy. During the spring semester, the students worked in teams to develop prototypes, models and examples of real solutions for energy reduction. This year’s projects included a device to extract heat from a shower’s wastewater stream and heat up incoming cold water; a vertical wind turbine built partially from urban trash, for use in poor Cairo neighborhoods; and a system that exposes uranium-binding polymer to seawater and retrieves it from the ocean. The subject was co-taught by CEE Professor Charles Harvey. For more information, please see here.
