2. Vibration-powered generator - Wikipedia

   en.wikipedia.org/wiki/Vibration-powered_generator

   Piezoelectric based generators use thin membranes or cantilever beams made of piezoelectric crystals as a transducer mechanism. When the crystal is put under strain by the kinetic energy of the vibration a small amount of current is produced thanks to the piezoelectric effect. These mechanisms are usually very simple with few moving parts, and ...

3. Van de Graaff generator - Wikipedia

   en.wikipedia.org/wiki/Van_de_Graaff_generator

   Shows using the Van de Graaff generator and several Tesla coils are conducted two to three times a day. [26] Many science museums, such as the American Museum of Science and Energy, have small-scale Van de Graaff generators on display, and exploit their static-producing qualities to create "lightning" or make people's hair stand up. Van de ...

4. Explosively pumped flux compression generator - Wikipedia

   en.wikipedia.org/wiki/Explosively_pumped_flux...

   Helical generators were principally conceived to deliver an intense current to a load situated at a safe distance. They are frequently used as the first stage of a multi-stage generator, with the exit current used to generate a very intense magnetic field in a second generator. Function of a helical generator. The MK-2 generators function as ...

5. Electron-beam processing - Wikipedia

   en.wikipedia.org/wiki/Electron-beam_processing

   The basic components of a typical electron-beam processing device include: [1] an electron gun (consisting of a cathode, grid, and anode), used to generate and accelerate the primary beam; and, a magnetic optical (focusing and deflection) system, used for controlling the way in which the electron beam impinges on the material being processed ...

6. High-frequency direction finding - Wikipedia

   en.wikipedia.org/wiki/High-frequency_direction...

   High-frequency direction finding, usually known by its abbreviation HF/DF or nickname huff-duff, is a type of radio direction finder (RDF) introduced in World War II. High frequency (HF) refers to a radio band that can effectively communicate over long distances; for example, between U-boats and their land-based headquarters.

7. Particle-beam weapon - Wikipedia

   en.wikipedia.org/wiki/Particle-beam_weapon

   A particle-beam weapon uses a high-energy beam of atomic or subatomic particles to damage the target by disrupting its atomic and/or molecular structure. A particle-beam weapon is a type of space-based directed-energy weapon , which directs focused energy toward a target using atomic scale particles.
