    If one of the game tweaks is running on Forge 1.7.10/1.12.2, intruders can remotely control both servers and gamers' devices. In one case, an attacker was using a new exploit variant to breach a ...

  3. Heat pump - Wikipedia

    en.wikipedia.org/wiki/Heat_pump

    e. A heat pump is a device that consumes work (or electricity) to transfer heat from a cold heat sink to a hot heat sink. Specifically, the heat pump transfers thermal energy using a refrigeration cycle, cooling the cool space and warming the warm space. [ 1] In cold weather, a heat pump can move heat from the cool outdoors to warm a house (e.g ...

    For example, a conventional heat pump system used to heat a building in Montana's −57 °C (−70 °F) low temperature or cool a building in the highest temperature ever recorded in the US—57 °C (134 °F) in Death Valley, California, in 1913 would require a large amount of energy due to the extreme difference between inside and outside air ...

  5. Thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_generator

    e. A thermoelectric generator ( TEG ), also called a Seebeck generator, is a solid state device that converts heat (driven by temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect [1] (a form of thermoelectric effect ). Thermoelectric generators function like heat engines, but are less bulky and ...

    Space Shuttle Discovery as it approaches the International Space Station during the STS-114 on 28 July 2005. The Space Shuttle thermal protection system (TPS) is the barrier that protected the Space Shuttle Orbiter during the searing 1,650 °C (3,000 °F) heat of atmospheric reentry.

  8. Specific heat capacity - Wikipedia

    en.wikipedia.org/wiki/Specific_heat_capacity

    Dimension. L 2 ⋅T −2 ⋅K −1. In thermodynamics, the specific heat capacity (symbol c) of a substance is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature. It is also referred to as massic heat capacity or as the specific heat. More formally it is the heat ...

  9. Heat wave - Wikipedia

    en.wikipedia.org/wiki/Heat_wave

    A heat wave [1] or heatwave, [2] sometimes described as extreme heat, is a period of abnormally hot weather. [ 3 ] : 2911 Definitions vary but are similar. [ 4 ] A heat wave is usually measured relative to the usual climate in the area and to normal temperatures for the season.
