European scientists developed machines to generate static electricity decades earlier. In 1663, Otto von Guericke generated static electricity with a device that used a sphere of sulfur. [ 1 ] Francis Hauksbee developed a more advanced electrostatic generator around 1704 using a glass bulb that had a vacuum.
This is a list of the world's largest machines, both static and movable in history. Building structure ... Tunnel boring machine: 99 m (324 ft 10 in) [8] 17.5 m (57 ...
Bucyrus-Erie was an American surface and underground mining equipment company. It was founded as Bucyrus Foundry and Manufacturing Company in Bucyrus, Ohio, in 1880.Bucyrus moved its headquarters to South Milwaukee, Wisconsin, in 1893.
Electrostatic machines are typically used in science classrooms to safely demonstrate electrical forces and high voltage phenomena. The elevated potential differences achieved have been also used for a variety of practical applications, such as operating X-ray tubes, particle accelerators, spectroscopy, medical applications, sterilization of food, and nuclear physics experiments.
The largest air-insulated Van de Graaff generator in the world, built by Dr. Van de Graaff in the 1930s, is now displayed permanently at Boston's Museum of Science. With two conjoined 4.5 m (15 ft) aluminium spheres standing on columns 22 ft (6.7 m) tall, this generator can often obtain 2 MV (2 million volts).
The next two largest units were captured by the United States and brought across the Atlantic Ocean, but they were half the size at 16,500 ton. As Cold War fears developed, American strategists worried that this would give the Soviet Air Force a crucial advantage and designed the Heavy Press Program to help win the arms race. [1] [4] [5] [6]
Big Brutus, while not the largest electric shovel ever built, is the largest electric shovel still in existence. The Captain, at 28 million pounds (13 kt) – triple that of Big Brutus – was the largest shovel and one of the largest land-based mobile machines ever built, only exceeded by some dragline and bucket-wheel excavators. It was ...
Marion's huge power shovel models eventually culminated in the world’s largest: the 1965 Marion 6360. The 6360 at the Captain Mine, Illinois, operated with a 180 cubic yard (138 cubic meter) dipper. With an estimated weight of 15,000 tons (13,600 tonnes), this machine is one of the heaviest mobile land machines ever built.
