We all owe Nikola Tesla a debt of gratitude: the Serbian-American inventor was integral in designing the alternating current electrical supply systems that power the modern world. Yesterday, on the day that wouldve been Teslas 158th birthday, Musk showed his appreciation for the man by pledging a million dollars to help build a Tesla museum. The pledge was prompted by Matthew Inman, who created webcomic The Oatmeal, and organized a successful crowdfunding campaign to purchase Teslas Wardenclyffe lab back in 2012.
