Harvesting lightning energy. Since the late 1980s, there have been several attempts to investigate the possibility of harvesting lightning energy. A single bolt of lightning carries a relatively large amount of energy (approximately 7 gigajoules [1] or about the energy stored in 38 Imperial gallons or 172 litres of gasoline).
Van de Graaff generator. A Van de Graaff generator is an electrostatic generator which uses a moving belt to accumulate electric charge on a hollow metal globe on the top of an insulated column, creating very high electric potentials. It produces very high voltage direct current (DC) electricity at low current levels.
Cloud seeding can be done by ground generators or planes. This image explaining cloud seeding shows a substance – either silver iodide or dry ice – being dumped onto the cloud, which then becomes a rain shower. The process shown in the upper-right is what is happening in the cloud and the process of condensation upon the introduced material.
Lightning is a natural phenomenon formed by electrostatic discharges through the atmosphere between two electrically charged regions, either both in the atmosphere or one in the atmosphere and one on the ground, temporarily neutralizing these in a near-instantaneous release of an average of between 200 megajoules and 7 gigajoules of energy, depending on the type.
A lightning strike can also create a large Lichtenberg figure in grass surrounding the point struck. These are sometimes found on golf courses or in grassy meadows. [ 12 ] Branching root-shaped " fulgurite " mineral deposits may also be created as sand and soil is fused into glassy tubes by the intense heat of the current.
Atmospheric electricity describes the electrical charges in the Earth's atmosphere (or that of another planet). The movement of charge between the Earth's surface, the atmosphere, and the ionosphere is known as the global atmospheric electrical circuit. Atmospheric electricity is an interdisciplinary topic with a long history, involving ...
Franklin bells (also known as lightning bells) are an early demonstration of electric charge designed to work with a Leyden jar or a lightning rod. Franklin bells are only a qualitative indicator of electric charge and were used for simple demonstrations rather than research. The bells are an adaptation to the first device that converted ...
Lightning Field, photo by Walter De Maria. The Lightning Field (1977) is a land art work in Catron County, New Mexico, by sculptor Walter De Maria. It consists of 400 stainless steel poles with solid, pointed tips, arranged in a rectangular 1 mile × 1 kilometre grid array. [1] It is maintained by the Dia Art Foundation as one of 12 locations ...
