North Korean state television has shown off a bus that reportedly runs on solar power.
The bus, which operates in the western city of Nampo, has 32 solar panels which power an electric motor through a bank of 50 batteries, the Korea Times reports, citing North Korean TV. The city's technology committee spokesman Jeong In-sung says that the vehicle is capable of carrying 140 passengers at 40km/h (25mph).
However, it's not known if the vehicle is fully solar powered, or if is has to be plugged into a charging station before it can take to the road, North Korea analysis website NK News says. One expert in solar technology tells the US-based site that the claim of 140 people riding a fully solar-powered bus has "no credibility".
