  2. Air ioniser - Wikipedia

    en.wikipedia.org/wiki/Air_ioniser

    There are two types of ionic air purifiers, the fanless and fan base ionizers. The fan base ionizer uses its fan to circulate air around the room rapidly, but it is noisier and consumes more energy, while the fanless types distribute air slowly, taking a longer time to purify air, but are noiseless and more energy efficient.

  3. Ionized-air glow - Wikipedia

    en.wikipedia.org/wiki/Ionized-air_glow

    Nitrogen glow Oxygen glow Electrical discharge in air Particle beam from a cyclotron. Ionized-air glow is the luminescent emission of characteristic blue–purple–violet light, often of a color called electric blue, by air subjected to an energy flux either directly or indirectly from solar radiation.

  4. Air purifier - Wikipedia

    en.wikipedia.org/wiki/Air_purifier

    Most ionizers produce less than 0.05 ppm of ozone, an industrial safety standard. There are two major subdivisions: the fanless ionizer and fan-based ionizer. Fanless ionizers are noiseless and use little power, but are less efficient at air purification. Fan-based ionizers clean and distribute air much faster.

  5. Negative air ions - Wikipedia

    en.wikipedia.org/wiki/Negative_air_ions

    Negative air ions (NAI) are important air component, generally referring to the collections of negatively charged single gas molecules or ion clusters in the air. They play an essential role in maintaining the charge balance of the atmosphere. [1] [2] The main components of air are molecular nitrogen and oxygen.

  8. Aeroponics - Wikipedia

    en.wikipedia.org/wiki/Aeroponics

    Aeroponics is the process of cultivating plants in an air or mist environment, eliminating the need for soil or an aggregate medium. The term "aeroponic" originates from the ancient Greek: aer (air) and ponos (labor, hardship, or toil).

  9. Thermogenic plant - Wikipedia

    en.wikipedia.org/wiki/Thermogenic_plant

    This is because the smaller plants do not have enough volume to create a considerable amount of heat. Large plants, on the other hand, have a lot of mass to create and retain heat. [5] Thermogenic plants are also protogynous, meaning that the female part of the plant matures before the male part of the same plant. This reduces inbreeding ...
