I prefer this concept over wireless. Note, the truck has a fossil fule engine to go off the grip for a short distance to unload, rest etc.
The concern of wireless is that wireless high power transmission is less efficient than wired, it rely on high frequency microwave which is more dangerous to human nearby especially the passengers. It is similar to wireless communication is always slower than wired counterpart.
Personally, I don't think any of this will be necessary. The battery revolution is just around the corner.
