Low-cost supercapacitors for energy storage

Rikhil Seshadri, Minnesota, USA 13-15

Seventeen percent of the world’s population does not have access to usable electricity. The hypothesis was that supercapacitors charged by solar panels or crank generators could power small LED lights and other devices such as small ultraviolet lamps that could be used for water treatment. This allows energy-poor regions of the world to start to address many of the problems they face, such as access to lighting and clean water. The supercapacitors should be made from locally available materials and easily fabricated without access to complex manufacturing facilities. They could also be made by volunteers at nonprofit organizations to be sent to places in need.
