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.
In alternating current, or AC, the electron flow reverses 120 times each second (in the USA) or 100 times each second (Europe). This is the way electricity is delivered to homes in nearly all of the developed world.
