2 nd Tesla Recall, page-4

The Tesla car battery is about 360 kgs and costs about $15K (roughly)

A Tesla car loaded is about 2000 kgs (2 ton)

Now lets look at a B Double"

Its fully loaded weight is 63 Ton or 31.5 times that of a car.

This, IMO, means that a B Double battery would cost $472,500 & weigh 11.34 ton

A B Double is the most economic way of moving goods Melb-Syd-Bne.

So the verdict: Not economically viable due to battery cost
& battery weight

Diesel for a B Double costs approximately $1/Klm.
