Electric organ (biology) in research because of their resemblance to nerve-muscle junctions. The stack of electrocytes has long been compared to a voltaic pile, and may even have inspired the invention of the battery, since the analogy was already noted by Alessandro Volta. While the electric organ is structurally similar to a battery, its cycle of operation is more like a Marx generator, in that the individual elements are slowly charged in parallel, then suddenly and nearly simultaneously discharged in series to produce a high voltage pulse. To discharge the electrocytes at the correct time, the electric eel uses its pacemaker nucleus, a
Anaerobic digestion streams and lakes released flammable gas. In 1778, the Italian physicist Alessandro Volta (1745-1827), the father of Electrochemistry, scientifically identified that gas as methane. In 1808 Sir Humphry Davy proved the presence of methane in the gases produced by cattle manure. The first known anaerobic digester was built in 1859 at a leper colony in Bombay in India. In 1895, the technology was developed in Exeter, England, where a septic tank was used to generate gas for the sewer gas destructor lamp, a type of gas lighting. Also in England, in 1904, the first dual-purpose tank for both sedimentation and
