TEEN scientist Taylor Wilson is the youngest person to build a nuclear fusion reactor -- in 2008, at age 14, in his parents’ garage! Fusion releases energy when two or more atoms join to form a new atom, as when hydrogen fuses into helium, producing the energy of the stars.

MEET Stella, the world’s first solar-powered family car. Built by Dutch university students, the four-seater’s rooftop solar panels help it go almost 400 miles on a single charge. Since it is energy-positive (it creates more power than it uses), it can also be a source of electricity.
