21Space tether — Artist s conception of satellite with a tether Space tethers are cables, usually long and very strong, which can be used for propulsion, stabilization, or maintaining the formation of space systems by determining the trajectory of spacecraft and… …
22Power engineering — Power engineering, also called power systems engineering, is a subfield of electrical engineering that deals with the generation, transmission and distribution of electric power as well as the electrical devices connected to such systems… …
23Kilogram — Kg redirects here. For other uses, see Kg (disambiguation). Kilogram A computer generated image of the international prototype kilogram (IPK). The IPK is the kilogram. The IPK, which is roughly the size of a golf ball, sits here alongside a ruler …
24Fusion power — The Sun is a natural fusion reactor. Fusion power is the power generated by nuclear fusion processes. In fusion reactions two light atomic nuclei fuse together to form a heavier nucleus (in contrast with fission power). In doing so they release a …
25Electrohydrodynamics — (EHD), also known as electro fluid dynamics (EFD) or electrokinetics, is the study of the dynamics of electrically conducting fluid. It is the study of the motions of ionised particles or molecules and their interactions with electric fields and… …
26Instabilité électrothermique — L instabilité électrothermique dite aussi instabilité de Velikhov ou instabilité d ionisation a été prédite par la théorie par le physicien russe Evgeny Velikhov en 1962, prédiction qui fut confirmée expérimentalement dès 1965[1]. C est une… …
27geomagnetic field — Magnetic field associated with the Earth. It is essentially dipolar (i.e., it has two poles, the northern and southern magnetic poles) on the Earth s surface. Away from the surface, the field becomes distorted. Most geomagnetists explain the… …
28Cavity magnetron — Magnetron with section removed (magnet is not shown) …
29Plasma (physics) — For other uses, see Plasma. Plasma lamp, illustrating some of the more complex phenomena of a plasma, including filamentation. The colors are a result of relaxation of electrons in excited states to lower energy states after they have recombined… …
30Gyro monorail — The gyro monorail, gyroscopic monorail, gyro stabilized monorail, or gyrocar all denote a single rail land vehicle, road or rail, which uses the gyroscopic action of a spinning wheel, which is forced to precess, to overcome the inherent inverted… …
