While you are hanging out on the Internet (in your underwear, maybe?) on a Saturday, kids that are smarter than either of us are out there getting ready to change the world. 18-year-old Eesha Khare, for instance, not only invented a supercapacitor that could someday be a phone battery that charges in just a couple of seconds; she also won $50,000 for it. Khare is one of the three big winners from the Intel International Science and Engineering Fair. She and 17-year-old Henry Lin—who created a model that simulates thousands of galaxies—picked up Intel Foundation Young Scientist Awards. Meanwhile, 19-year-old Ionut Budisteanu won the Gordon E. Moore Award and $75,000 for his AI model that could lead to a cheaper self-driving car. Khare’s invention is the one with some really immediate potential though, and quick-charging phones is something we all want.
