Prokop Divis lightning rod designs
Already during his tenure in Louka Monastery Divis he dealt Hydrotechnology and built several water mains. After he moved to Přímětická rectory, set up a small laboratory here and became interested in static electricity. He constructed a device "electrum," which consisted of a glass ball in the stand, at which rotational friction and gaining power. With this device perform simple electrostatic experiments. When they began to realize that lightning is actually a huge electrical spark and that the charge could be sucked out of the clouds and lead the country.
In 1759 it affected the whole of Central Europe an unprecedented drought. In Přímětice However, the villagers believed that the true cause of the drought is Diviš lightning which scatters the clouds. Therefore, in March 1760 they broke into the rectory garden Přímětice, loosen the grounding chains and the whole structure of the lightning torn down and destroyed. Fortunately Divis left a detailed description in his treatise "Descriptio Machinae meteorologicae".
