1954: Invention of the solar battery by Bell Telephone scientists, Calvin Souther Fuller, Daryl Chapin and Gerald Pearson capturing the Sun's power. First practical means of collecting energy from the Sun and turning it into a current of electricity. 1955: The hovercraft is patented by Christopher Cockerell.
The electric guitar was a key instrument in the development of musical styles that emerged since the late 1940s, such as Chicago blues, early rock and roll, rockabilly, and 1960s blues rock. Electric guitars are used in almost every popular music genre. [239] U.S. patent #2,089,171 was filed by Beauchamp on June 2, 1934, and issued on August 10 ...
It was the first convenient battery for the masses and made portable electrical devices practical, and led directly to the invention of the flashlight. The zinc–carbon battery (as it came to be known) is still manufactured today. In parallel, in 1887 Wilhelm Hellesen developed his own dry cell design. It has been claimed that Hellesen's ...
In the early 1920s, there was a growing interest in the development of domestic applications for electricity. [39] Public interest led to exhibitions such featuring "homes of the future" and in the UK, the Electrical Association for Women was established with Caroline Haslett as its director in 1924 to encourage women to become involved in ...
Some of the devices which would enable wireless telegraphy were invented before 1900. These include the spark-gap transmitter and the coherer with early demonstrations and published findings by David Edward Hughes (1880) [9] and Heinrich Rudolf Hertz (1887 to 1890) [10] and further additions to the field by Édouard Branly, Nikola Tesla, Oliver Lodge, Jagadish Chandra Bose, and Ferdinand Braun.
Voltages used for electric power transmission increased throughout the 20th century. [50] The first "high voltage" AC power station, rated 4-MW 10-kV 85-Hz, was put into service in 1889 by Sebastian Ziani de Ferranti at Deptford, London. [33] The first electric power transmission line in North America operated at 4000 V.
