ELON MUSK HAS always dreamed big, and tonight he showed off his biggest reverie yet: the fully electric Tesla Semi. Powered by a massive battery and capable of hauling 80,000 pounds, it can ramble 500 miles between charges. It'll even drive itself—on the highway, at least.1
And Musk promises production will start in 2019.
The big rig, which Musk unveiled at SpaceX's Hawthorne, California headquarters Thursday night, is just the latest step in his mission to make humanity forget about planet-killing fossil fuels and embrace the gospel of electric power.
That is, of course, if he can convince the trucking industry it's time for a new way of moving stuff around—and if he can actually make the thing.
