A hovercraft (pl.: hovercraft [1]), also known as an air-cushion vehicle or ACV, [2] is an amphibious craft capable of travelling over land, water, mud, ice, and various other surfaces. Hovercraft use blowers to produce a large volume of air below the hull , or air cushion, that is slightly above atmospheric pressure .
It is not possible to turn the hoverboard on a dime, or dash around town like Fox famously did, but subtle changes of direction can be made using touch sensitive plates under the feet.
A hoverboard (or hover board) is a fictional levitating board used for personal transportation, first described in science-fiction, and made famous by the appearance of a skateboard-like hoverboard in the film Back to the Future Part II. Many attempts have been made to invent a functioning hoverboard.

A hole opened up in the ice and Bågenholm's head and torso were pulled in as meltwater filled her clothes. [10] Her body became trapped under the ice, which was 20 centimetres (7.9 in) thick. [12] When Falkenberg and Næsheim found Bågenholm, only her feet and skis were above the ice. [10]
The first stage of cold water immersion syndrome, the cold shock response, includes a group of reflexes lasting under 5 min in laboratory volunteers and initiated by thermoreceptors sensing rapid skin cooling. Water has a thermal conductivity 25 times and a volume-specific heat capacity over 3000 times that of air; subsequently, surface cooling ...
[6] [20] [28] This will allow the PSCs to break ice with a thickness between 6 and 8 feet (1.8 and 2.4 m). [4] Designed according to the International Association of Classification Societies (IACS) Unified Requirements for Polar Class Ships , the PSCs will be strengthened to Polar Class 2 which is intended for vessels operating year-round in ...
