A beautiful and very tolerant country, Sweden, in Russia is better known for some reason as the homeland of the sexual concept of the “Swedish family” and the musical group “Abba”.
In fact, the largest Scandinavian power has made much more for the world than many modern inhabitants.
Say, it was in this state, around the middle of the 18th century, that a scientist named Christopher Polgem lived. It was he who, remembering, perhaps, the device of the Roman term and depicted on paper a drawing of a heating system with air channels.
True, there is also a version that not proud Latins pushed at this act of the wise Polarm, but their own compatriots, who lived under the king of Goros. Well, or, as archaeologists testify, in the Stone Age, about 6,000 years ago. This is evidenced, in particular, the fact that it was in Sweden that the remains of one rather primitive system were discovered. Namely – just what we call the warm floor. With the help of special channels, the ancestors of modern Swedes lifted warm air to the very surface of the earth and warmed those who slept there.
