Clean drinking water—it's an underappreciated luxury coming at long last to students in Flint, Mich., thanks to Elon Musk. Following his July vow to assist in the Flint water crisis, the Tesla and SpaceX CEO and the Musk Foundation donated $480,350 to the Flint City School District, allowing for new water-filtration systems at all 12 district schools and an administration building, per CNET. The district celebrated the work, to be completed by January, in a tweet of thanks, reports Business Insider. "You're most welcome. Hope to do more to help in the future," Musk replied.
