When ordinary negative polarity cloud-ground lightning discharges into a grounding substrate, greater than 100 million volts (100 MV) of potential difference may be bridged. [2] Such current may propagate into silica -rich quartzose sand, mixed soil, clay , or other sediments, rapidly vaporizing and melting resistant materials within such a ...
We implemented a two-dimensional (2D) cloak because its fabrication and measurement requirements were simpler than those of a 3D cloak. [ 3 ] Before the actual demonstration, the experimental limits of the transformational fields were computationally determined, in addition to simulations, as both were used to determine the effectiveness of the ...
An operational, non-fictional cloaking device might be an extension of the basic technologies used by stealth aircraft, such as radar-absorbing dark paint, optical camouflage, cooling the outer surface to minimize electromagnetic emissions (usually infrared), or other techniques to minimize other EM emissions, and to minimize particle emissions from the object.
In modern times, it is worn over the habit during liturgical services. Originally, cowl may have referred simply to the hooded portion of a cloak. In contemporary usage, however, it is distinguished from a cloak or cape (cappa) by the fact that it refers to an entire closed garment consisting of a long, hooded garment with wide sleeves.
Powerline worker performs maintenance of a lightning arrester on an electrical transmission tower in New Brunswick, Canada. A lightning arrester (alternative spelling lightning arrestor) (also called lightning isolator) is a device, essentially an air gap between an electric wire and ground, used on electric power transmission and telecommunication systems to protect the insulation and ...
Cellini's Perseus (1545–54), wearing the Cap of Invisibility and carrying the head of Medusa. In classical mythology, the Cap of Invisibility (Ἅϊδος κυνέη (H)aïdos kyneē in Greek, lit. dog-skin of Hades) is a helmet or cap that can turn the wearer invisible, [1] also known as the Cap of Hades or Helm of Hades.

The Ford F-150 Lightning is a battery electric full-size light duty truck unveiled by Ford Motor Company in May 2021 as part of the fourteenth generation Ford F-Series. Four models have been announced, and all models initially will be dual-motor, four-wheel-drive, with EPA range estimates of 240–320 mi (390–510 km).
