During the presentation, Musk says that Tesla will guarantee $.07/kwh for all their trucks. So his numbers are based upon that.

I wonder how that guarantee will be realized? Subsidies? Unless I am missing something, this seems to be artificially lower operating costs of the Semi in order to make to favorable to diesel.

Solar chargers built by Tesla’s solar business unit

they said their factory would be powered by solar panels (it's not) and their superchargers would be solar powered as well (they're not). Kind of one of those things like battery swapping that's not as practical as it sounds.

Not an expert in this field, with costs or anything. My guess if not subsidies, it's a bet that electric energy will be cheaper, or batteries get more efficient to meet that price point in the 2-3 years it takes to ramp up production. In that time, they can get pre-orders.

This reminds me of car companies advertising guaranteed gas prices for certain types of cars back when gas started hitting $3/$4 mark. I would see commercials of new cars saying $2.50/g for the next 5 years or something similar.

Chrysler, $2.99/g for 3 years if you buy new car.
