Even better is the statement from the article - "But is it green? It’s better than putting diesel in a car, says Edwards, because the constant running rate of the gennie uses the fuel more efficiently than idling and accelerating in a car."

You know how many stop signs, red lights and traffic jams there are on the Eyre Highway crossing South and Western Australia, which is where this articles starts? ZERO, and if you do stop you best be well clear of the road otherwise the next road train will run you and your EV over.

Regarding the Tesla RV concept, if they use the semi as a model with even half the 1-megawatt battery pack the semi is likely to have you are in for some long recharge times even if you can achieve a 1C constant rate. Pull in with 1/4 charge remaining and you might as well take a nap since the 50kW diesel charging station is going could take 7+ hours if the generator can give you all 50kW of its capacity and you don't use any power during the charge time. If you somehow make it to a superstation with a 150kW recharge rate your wait is better at around 2 1/2 hour as long as no one is using the other side of supercharge to power up their EV with will drop the rate to 75kW. Make camp at a current US 12kW (50 amp site) RV campsite? 31+ hours. More if you start siphoning off power for habitability. A 30 amp site, you might be there a week.

BTW peak power rates for Western Australia average 36.41 cents (USD) per kWh so fully charge your 1/4 full 500kW Tesla RV battery will be $136.53. That is before whoever you are getting power from adds in any surcharges that will probably consume the $63.72 savings over filling up a 3/4 empty 70-gallon gas tank in 5 or so minutes based on the current gasoline cost for Western Australia.

Ummm. The article is about an interim measure to provide power for EV’s. Not semis that don’t exist yet.
