ガス灯
Gas lighting was one of the most debated technologies of the first industrial revolution. In Paris, as early as 1823, controversy forced the government to devise safety standards (Fressoz, 2007). The residues produced from distilled coal were often either drained into rivers or stored in basins which polluted (and still pollute) the soil. One early exception was the Edinburgh Gas Works where, from 1822, the residues were carted and later piped to the Bonnington Chemical Works and processed into valuable products.
