The masts of this line were designed for eventual upgrade to 380 kV. However the first transmission at 380 kV in Germany was on October 5, 1957 between the substations in Rommerskirchen and Ludwigsburg–Hoheneck. The world's first 380 kV power line was built in Sweden, the 952 km Harsprånget – Hallsberg line in 1952.
In 1957, she was sold to Hugo Neu Corporation of New York City and was used then as a power facility abroad by the International Steel and Metal Corporation. In 1959, she was renamed Somerset. [4] MH-1A, the first floating nuclear powership. The first floating nuclear reactor ship was the MH-1A, used in the Panama canal zone from 1968 to 1975.
On November 12, 2017 Guangzhou Shipyard International (GSI) launched what may be the world's first all-electric, battery-powered inland coal carrier. The 2,000 dwt vessel will carry bulk cargo for up to 40 nautical miles per charge.
The Danish physicist Valdemar Poulsen creates the world's first magnetic recording and reproduction, using a 1 mm thick steel wire as a magnetizable carrier. Nikola Tesla publicly demonstrated the first wireless remote control of a model ship. 1899: The dog "Nipper" is used in "His Master's Voice", the trademark for gramophones and records.
Used early on in electrical generation and to power ships, turbines were bladed wheels that created rotary motion when high pressure steam was passed through them. The efficiency of large steam turbines was considerably better than the best compound engines, while also being much simpler, more reliable, smaller and lighter all at the same time ...
Columbia was the first ship to carry a dynamo powering electric lights instead of oil lamps and the first commercial use of electric light bulbs outside of Thomas Edison's Menlo Park, New Jersey laboratory. [7] [11] [12] Due to this, a detailed article and composite illustration of Columbia was featured in the May 1880 issue of Scientific ...
It was the first submarine in the world with electric battery-powered propulsion. [8] He developed the theory of gliding flight, developed a method for the manufacture of ship and plane propellers (1892), and presented a general theory for screw-propeller thrust (1920). He is known for developing several models of early submarines for the ...
A simple electromagnet, consisting of an insulated wire wound around an iron core. An electric current passing through the wire creates a Magnetic field, with a north pole at one end and a south pole at the other. The first application of electricity that was put to practical use was electromagnetism. [18]
