  2. Plasma-powered cannon - Wikipedia

    en.wikipedia.org/wiki/Plasma-powered_cannon

    A clear disadvantage of the plasma cannon is its weight. Even a small plasma cannon with only the firepower of an air gun weighs about 20 kg (44 lb) (without current supply). A foot soldier thus could not carry a plasma cannon powerful enough to be useful. It would have to be mounted in a stationary position or on a vehicle.

  3. Radiological warfare - Wikipedia

    en.wikipedia.org/wiki/Radiological_warfare

    Radiological warfare is any form of warfare involving deliberate radiation poisoning or contamination of an area with radiological sources.. Radiological weapons are normally classified as weapons of mass destruction (WMDs), [1] although radiological weapons can also be specific in whom they target, such as the radiation poisoning of Alexander Litvinenko by the Russian FSB, using radioactive ...

  4. Directed-energy weapon - Wikipedia

    en.wikipedia.org/wiki/Directed-energy_weapon

    The MARAUDER (Magnetically Accelerated Ring to Achieve Ultra-high Directed-Energy and Radiation) used the Shiva Star project (a high energy capacitor bank which provided the means to test weapons and other devices requiring brief and extremely large amounts of energy) to accelerate a toroid of plasma at a significant percentage of the speed of ...

  5. Death ray - Wikipedia

    en.wikipedia.org/wiki/Death_ray

    While based in fiction, research into energy-based weapons inspired by past speculation has contributed to real-life weapons in use by modern militaries sometimes called a sort of "death ray", such as the United States Navy and its Laser Weapon System (LaWS) deployed in mid-2014. [5] [6] Such armaments are technically known as directed-energy ...

  6. Project Excalibur - Wikipedia

    en.wikipedia.org/wiki/Project_Excalibur

    Plasma is a gas, and its energy causes it to adiabatically expand according to the ideal gas law. As it does, its temperature drops, eventually reaching a point where the electrons can reconnect to nuclei. The cooling process causes the bulk of the plasma to reach this temperature at roughly the same time.

  7. Fold mountains - Wikipedia

    en.wikipedia.org/wiki/Fold_mountains

    Fold mountains form in areas of thrust tectonics, such as where two tectonic plates move towards each other at convergent plate boundary.When plates and the continents riding on them collide or undergo subduction (that is – ride one over another), the accumulated layers of rock may crumple and fold like a tablecloth that is pushed across a table, particularly if there is a mechanically weak ...

  8. List of fictional countries set on Earth - Wikipedia

    en.wikipedia.org/wiki/List_of_fictional...

    This is a list of fictional countries from published works of fiction (books, films, television series, games, etc.). Fictional works describe all the countries in the following list as located somewhere on the surface of the Earth as opposed to underground, inside the planet, on another world, or during a different "age" of the planet with a different physical geography.

  9. Antimatter weapon - Wikipedia

    en.wikipedia.org/wiki/Antimatter_weapon

    An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon.Antimatter weapons are currently too costly and unreliable to be viable in warfare, as producing antimatter is enormously expensive (estimated at US$6 billion for every 100 nanograms), the quantities of antimatter generated are very small, and current ...
