  2. Lightning rod - Wikipedia

    en.wikipedia.org/wiki/Lightning_rod

    A lightning rod or lightning conductor (British English) is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. If lightning hits the structure, it is most likely to strike the rod and be conducted to ground through a wire, rather than passing through the structure, where it could start a fire or ...

  3. Harvesting lightning energy - Wikipedia

    en.wikipedia.org/wiki/Harvesting_lightning_energy

    To facilitate the harvesting of lightning, a laser-induced plasma channel (LIPC) could theoretically be used to influence lightning to strike in a predictable location. A high power laser could be used to form an ionized column of gas, which would act as an atmospheric conduit for electrical discharges of lightning, which would direct the lightning to a ground station for harvesting.

  4. Franklin bells - Wikipedia

    en.wikipedia.org/wiki/Franklin_bells

    The system of operation of the Franklin clock considers that the electrostatic force generated by an electric field is used to move the pendulums that strike two metal bells. [8] [9] The Franklin bells uses a metal rod as a lightning rod to attract current. One bell is connected to the lightning rod and the other bell is connected to the ground.

  5. Lightning strike - Wikipedia

    en.wikipedia.org/wiki/Lightning_strike

    Hundreds of devices, including lightning rods and charge transfer systems, are used to mitigate lightning damage and influence the path of a lightning flash. A lightning rod (or lightning protector) is a metal strip or rod connected to earth through conductors and a grounding system, used to provide a preferred pathway to ground if lightning ...

  6. Lightning detector - Wikipedia

    en.wikipedia.org/wiki/Lightning_detector

    Because most of the total lightning is from IC flashes, this ability to quantify storm intensity occurs mostly through detection of IC discharges. Lightning detectors that sense only low frequency energy detect only IC flashes that are nearby, so they are relatively inefficient for predicting microbursts and quantifying convective intensity.

  7. Lightning - Wikipedia

    en.wikipedia.org/wiki/Lightning

    The electric field is strongest on grounded objects whose tops are closest to the base of the thundercloud, such as trees and tall buildings. If the electric field is strong enough, a positively charged ionic channel, called a positive or upward streamer, can develop from these points. This was first theorized by Heinz Kasemir.

  9. Kite experiment - Wikipedia

    en.wikipedia.org/wiki/Kite_experiment

    The experiment's purpose was to investigate the nature of lightning and electricity, which were not yet understood. Combined with further experiments on the ground, the kite experiment demonstrated that lightning and electricity were the result of the same phenomenon.
