Hmmm, I like autonomously hauling containers through tunnels as an application for Tesla.
* Could this application use battery chemistries unsuitable for other transportation applications?
In most cases and areas underground, temperatures are stable and relatively benign (there are exceptions ) so a narrower operating temperature range might be acceptable. The distances are probably mostly short and weight may be less of a factor, so the energy density requirements might be lower. Rapid acceleration and highish speeds might make power density the more desirable characteristic.
* Could it create an early entry point for the Tesla Network? It’d be a good way to encourage citizens and regulators to get warmed up to the idea of autonomy. Probably no or minimal regulatory approval needed — it is presumably a private way. Of course, the Boring Company could also run the vehicles.
* Tunnels are protected from the elements, so minimal protection is needed on the transporter. Perhaps just a skateboard as this suggests. This opens up lots of possibilities for utilizing volume for components (other than current rate limiting battery supplies) and possibly sharing lines while not taking up a lot of design cycles and logistics bandwidth.
All in all a nice application especially if other battery technology or capacity can be used.
Roads leading to container ports are often congested, built up old towns restricting options. Relatively short tunnels going to pick up points closer to major roads could help. Over time, simply extend.
