  2. Air ioniser - Wikipedia

    en.wikipedia.org/wiki/Air_ioniser

    An air ioniser (or negative ion generator or Chizhevsky's chandelier) is a device that uses high voltage to ionise (electrically charge) air molecules. Negative ions, or anions , are particles with one or more extra electrons , conferring a net negative charge to the particle.

  3. Ion wind - Wikipedia

    en.wikipedia.org/wiki/Ion_wind

    An electrostatic pinwheel, or corona spinner, attached to a small Wimshurst machine (electrostatic generator) is shown stationary and rotating. Ion wind, ionic wind, corona wind or electric wind is the airflow of charged particles induced by electrostatic forces linked to corona discharge arising at the tips of some sharp conductors (such as points or blades) subjected to high voltage relative ...

  4. Air purifier - Wikipedia

    en.wikipedia.org/wiki/Air_purifier

    An air purifier or air cleaner is a device which removes contaminants from the air in a room to improve indoor air quality. These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics , and at reducing or eliminating second-hand tobacco smoke .

  5. Air freshener - Wikipedia

    en.wikipedia.org/wiki/Air_freshener

    Air fresheners from Febreze. Air fresheners are products designed to reduce unwanted odors in indoor spaces, to introduce pleasant fragrances, or both. They typically emit fragrance to mask odors but may use other methods of action such as absorbing, bonding to, or chemically altering compounds in the air that produce smells, killing organisms that produce smells, or disrupting the sense of ...

  6. Magnetohydrodynamic generator - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_generator

    An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current. The MHD generator uses hot conductive ionized gas (a plasma) as the moving conductor. The mechanical dynamo, in contrast, uses the motion of mechanical devices to accomplish this.

  7. Ion-propelled aircraft - Wikipedia

    en.wikipedia.org/wiki/Ion-propelled_aircraft

    The air mass in the gap between the electrodes is impacted repeatedly by excited particles moving at high drift velocity. This creates electrical resistance, which must be overcome. The result of the neutral air caught in the process is to effectively cause an exchange in momentum and thus generate thrust.

  8. Electroactive polymer - Wikipedia

    en.wikipedia.org/wiki/Electroactive_polymer

    Examples of ionic EAPs are conductive polymers, ionic polymer-metal composites (IPMCs), and responsive gels. Yet another example is a Bucky gel actuator, which is a polymer-supported layer of polyelectrolyte material consisting of an ionic liquid sandwiched between two electrode layers, which is then a gel of ionic liquid containing single-wall ...

    The DELTA Pro 3 and DELTA Pro Ultra offer higher capacities, [16] [18] with app-based monitoring and control for home backup power, [18] and are expandable for increased energy needs. [ 18 ] [ 16 ] The DELTA Pro 3 is the first of EcoFlow's units to include the company's X-Core 3.0, an integrated architecture system.
