Although for now, even switching the touring boats to electric engines, which should be easy enough (why do the private companies benefit from public space selling 25€/seat tours in the city center while spewing huge clouds of exhaust into the air and dumping oil and dirt into the river? – they should at least switch to clean engines and for a limited km range tours this would be sensible) is not done in Berlin. Even the ferries that the transport company operates are not all electric (cause they actually rent some of them from the private boat touring companies), although there they could even be tethered and not require a battery at all. Anyway, all of this is just optimistic hippie talk, I will rather just move to Switzerland than wait for Germany to clean up.
