On Nov. 17, 2017, NPR’s Bill Chappell reported “Tesla Unveils Its Electric ‘Semi’ Truck, And Adds A Roadster”. The tractor trailer truck is streamlined and can haul 800,000 gross vehicle weight (GVW) up a five percent grade at 65 miles an hour up to 500 miles before charging. This is a big deal. Most people can barely afford to buy or lease an electric car, but lots of companies can write off a fleet of trucks as a business expense. They might even get an environmental benefit. There is a freeway down in Long Beach California that is bumper to bumper around the clock. Replacing diesel with electric would clear the air quite a bit. Cross country hauling would mean slipping in a new truck every 500 miles. It is possible that means drivers would get a chance to rest and have fewer accidents. One interesting detail. There is only one seat and it is in the center of the cab. It means you can sell it around the world no matter what side of the road people drive on. Frankly I think the extra room is for the technology that drives the truck without a human driver.
