Even a dedicated rail link or even a whole network would be much, much cheaper than a conveyor, which are also notoriously unreliable and would halt the entire system on every fault.
From the concept pics they have up it looks more like each container is a self contained 'train'. They say it is for zero emissions but it takes energy to move cargo. 'conveyor' belts do not have free energy. You have to move the belt and the cargo.
Interesting idea though. I hope they come up with some cool ideas.
Surely just use self-driving trains.
