Emily Cummins of the United Kingdom is only 23, but she's already invented a solar-powered refrigerator currently being used in Africa. The thing uses zero electricity, can be partially manufactured locally, and keeps its contents at a cool 6 degrees Celsius (43 F).
"I'm passionate about encouraging young people to reach their creative potential, especially in the field of sustainable design," said Cummins, who learned to tinker in her grandfather's shop as a child. Cummins was recently named an Oslo Business for Peace Honoree, an award bestowed by Nobel Prize winners, and also won a Ten Outstanding Young Persons of the World award from Junior Chamber International, a global nonprofit youth service organization.
