Kalmia species are used as food plants by the larvae of some lepidopteran species including Coleophora kalmiella which feeds exclusively on Kalmia.hey grow in acidic soils, with different species in wet acid bog habitats (K. angustifolia, K. polifolia) and dry, sandy soils (K. ericoides, K. latifolia). Kalmia was named by Linnaeus to honour his friend the botanist Pehr Kalm, who collected it in eastern North America during the mid-18th century.
Tesla electrified Niagara Falls!! In 1895, the Westinghouse Company and Nicola Tesla built the first hydroelectric alternating current system at Niagara Falls. Tesla was determined that the awesome power of the Falls should be harnessed to the awesome power of polyphase alternating current.
But other than that, there was little real progress until the English scientist William Gilbert in 1600 described the electrification of many substances and coined the term electricity from the Greek word for amber. As a result, Gilbert is called the father of modern electric power. In 1660, Otto von Guericke invented a crude machine for producing static electricity. It was a ball of sulfur, rotated by a crank with one hand and rubbed with the other.
