Lightning Lightning is the emission of light due to electricity discharging from cloud-to-cloud or from cloud-to-ground. This electrical discharge results from the buildup of positive and negative charges within a thunderstorm. In a calm sky, the positive and negative charges are all mixed up. However, during a thunderstorm, rapidly rising air interacts with rapidly falling air to create separately positive and negative charged areas within the cloud. The positive areas are where protons are located, while the negative areas are where the electrons are located. Protons are important parts of atoms that do not typically float around on their own, unless you are causing a nuclear reaction by splitting the atom. ...read more.


Cloud-to-ground Lightning flash. Because opposites attract, negative charges at the bottom of the thunder cloud want to link up with positive charges at Earth's surface. Negative charges are carried down from the base of the cloud to the ground. This is an originator of the Lightning, called a stepped leader. When the stepped leader is approaching the ground, a positive charge shoots up to meet the stepped leader. This positive charge is known as a streamer. When the stepped leader and the streamer do meet up, a short circuit occurs. This short circuit allows the positive charges to be carried up into the cloud. ...read more.


So while your car may be hit by Lightning, as long as you stay inside, you are safe. Lord Kelvin in 1887 did some work on the explanation of the Skin Effect Ground current are circles of energy caused by lightning hitting the ground which then spreads out along the surface. If it contacts a fence or a water pipe or wire entering a house it can be transmitted for quite a distance and cause injury to persons near these paths, this is because of conduction. Harnessing lightning The idea of harnessing the power of lightning goes further back than the time of Benjamin Franklin. This can't be done. It would be hard to get enough lightning strikes occurring and the energy from lightning is converted to other energy forms like thunder, heat, light, and radio waves.
