"Travel by Wire!" is a science fiction short story by English writer Arthur C. Clarke. His first published story, it was first published in December 1937. This story is a humorous record on the development of the "radio-transporter" (actually a teleportation machine), and the various technical difficulties and commercial ventures that resulted.
Wireless power transfer (WPT; also wireless energy transmission or WET) is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, an electrically powered transmitter device generates a time-varying electromagnetic field that transmits power across space to a receiver device; the receiver ...
Efficient long-distance transmission of electric power requires high voltages. This reduces the losses produced by strong currents. Transmission lines use either alternating current (AC) or direct current (DC). The voltage level is changed with transformers. The voltage is stepped up for transmission, then reduced for local distribution.
It is a common subject in science fiction and fantasy literature. Teleportation is often paired with time travel, being that the traveling between the two points takes an unknown period of time, sometimes being immediate. An apport is a similar phenomenon featured in parapsychology and spiritualism. [1] [2]
Technology in science fiction is a crucial aspect of the genre. [ 1 ] [ 2 ] As science fiction emerged during the era of Industrial Revolution , the increased presence of machines in everyday life and their role in shaping of the society was a major influence on the genre.
Energy shield from the game Second Life. In speculative fiction, a force field, sometimes known as an energy shield, force shield, energy bubble, or deflector shield, is a barrier produced by something like energy, negative energy, dark energy, electromagnetic fields, gravitational fields, electric fields, quantum fields, telekinetic fields, plasma, particles, radiation, solid light, magic, or ...
Power transmission is the movement of energy from its place of generation to a location where it is applied to perform useful work. Power is defined formally as units of energy per unit time . In SI units:
The Way Things Work is a 1988 nonfiction book by David Macaulay with technical text by Neil Ardley.It is a whimsical introduction to everyday machines and the scientific principles behind their operation, describing machines as simple as levers and gears and as complicated as radio telescopes and automatic transmissions.
