Who He Is: Marin Soljačić, assistant professor of physics at MIT
What He Did: Soljačić invented “WiTricity,” the first steps toward wireless electricity. That is, moving electricity without cables. It all started when Soljačić awoke in the middle of the night for the umpteenth time to his chirping cell phone, reminding him to plug it in. It occurred to him that in this day and age, cell phones should be able to plug themselves in and save him the hassle.
