I'm very aware of that Tom Scott video, don't worry. It is an okay middleground, but look at the people in comments pointing out the wear on the trolley.
WTF Germany how did I not know this was a thing and why aren't we doing it here in the US?
Question though. Obviously the wires can't cover every road and the truck sometimes has to drive off the wired road. Do they have small batteries to carry them between the wires?
There are 5 testing areas for this atm and only a handful of trucks which use that. These are hybrid trucks having batteries and electrical engines besides the main traditional diesel engine. So it's far from an widely adopted tech right now.
If they can get that to work this can be massive, assuming we don't want to improve our rail infrastructure. It will also keep trucks from the passing lane
Is this a trial or is it getting installed all over? It's the best solution to electrify goods transport by road. Only a small battery required for off grid to delivery point and back
