Mulle Mek collects an electric car. Yuhanson G.

The skillful mechanic Mulle Mek is the hero of many children's books. From a pile of unnecessary pieces of iron, he can make a car, a motorcycle, an airplane, and much more, and at the same time explain in simple words how all these machines work.

This time Mullah decided to assemble an environmentally friendly electric car. But he doesn’t understand electricity very much, so friends come to the rescue-Lucas Diesel and Doris Raysson. They will tell Mullah and readers what electric current is, where it comes from and how it works.
