Tesla unveiled to much fanfare, a DIESEL electric train to carry workers to and from their Berlin Gigafactory. LOL!
Dave runs the numbers on whether or not they could have used a Battery Electric Train (BEMU) instead of diesel electric. And could they have powered it from the solar panels on the train station roof?
