I saw this on the Today show this morning:
https://www.edisonmotors.ca They're a startup company that is developing a diesel electric logging truck, with a large battery pack on board. So far they've built a proof of concept truck using a 1962 Kenworth. It has a 3306 CAT diesel generator charging a battery bank, running a frame mounted electric drive motor into a traditional set of 46,000 rear ends. From what the owner said, they want to move towards motors in the wheels for production trucks, and are also planning on retrofit kits for existing trucks. It will be interesting to see if they can succeed.
