Hail Cannon
A hail cannon is a shock wave generator claimed to disrupt the formation of hailstones in the atmosphere. These devices frequently engender conflict between farmers and neighbors when used, because they are loudly and repeatedly fired every 1 to 10 seconds while a storm is approaching and until it has passed through the area, yet there is no scientific evidence for their effectiveness. Historical use In the French wine-growing regions, church-bells were traditionally rung in the face of oncoming storms and later replaced by firing rockets or cannons. Modern systems A mixture of acetylene and oxygen is ignited in the lower chamber of the machine. As the resulting blast passes through the neck and into the cone, it develops into a shock wave. This shock wave then travels through the cloud formations above, a disturbance which manufacturers claim disrupts the growth phase of hailstones. Manufacturers claim that what would otherwise have fallen as hailstones then falls as slus ...

Machine
A machine is a physical system that uses power to apply forces and control movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems. Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input force, known today as mechanical advantage. Modern machines are complex systems that consist of structural elements, mechanisms and contr ...

Weather Modification
Weather modification is the act of intentionally manipulating or altering the weather. The most common form of weather modification is cloud seeding, which increases rainfall or snowfall, usually for the purpose of increasing the local water supply. Weather modification can also have the goal of preventing natural disaster, damaging weather, such as hail or hurricanes, from occurring; or of provoking damaging weather against an enemy, as a tactic of military or economic warfare like Operation Popeye, where clouds were Cloud seeding, seeded to prolong the monsoon in Vietnam. Weather modification in warfare has been banned by the United Nations under the Environmental Modification Convention. History A popular belief in Northern Europe was that shooting prevents hail, which thus caused many agricultural towns to fire cannons without ammunition. Veterans of the Seven Years' War, Napoleonic wars, and the American Civil War reported that rain fell after every large battle. After thei ...

Pseudoscience
Pseudoscience consists of statements, beliefs, or practices that claim to be both scientific and factual but are incompatible with the scientific method. Pseudoscience is often characterized by contradictory, exaggerated or unfalsifiable claims; reliance on confirmation bias rather than rigorous attempts at refutation; lack of openness to evaluation by other experts; absence of systematic practices when developing hypotheses; and continued adherence long after the pseudoscientific hypotheses have been experimentally discredited. It is not the same as junk science. The demarcation between science and pseudoscience has scientific, philosophical, and political implications. Philosophers debate the nature of science and the general criteria for drawing the line between scientific theories and pseudoscientific beliefs, but there is widespread agreement "that creationism, astrology, homeopathy, Kirlian photography, dowsing, ufology, ancient astronaut theory, Holocaust den ...

Cloudbuster
A cloudbuster is a device designed by Austrian Psychoanalysis, psychoanalyst Wilhelm Reich (1897–1957), which Reich claimed could produce rain by manipulating what he called "Orgone, orgone energy" present in the atmosphere. The cloudbuster was intended to be used in a way similar to a lightning rod: focusing it on a location in the sky and grounding it in some material that was presumed to absorb orgone—such as a body of water—would draw the orgone energy out of the atmosphere, causing the formation of clouds and rain. Reich conducted dozens of experiments with the cloudbuster, calling the research "Cosmic orgone engineering".Myron Sharaf, Sharaf, Myron (1994). ''Fury on Earth: A Biography of Wilhelm Reich''. Da Capo Press (first published by St. Martin's Press, 1983), pp. 379−380. *Also see There have been no verified instances of a cloudbuster actually working and producing noticeable weather change, such as causing rain. Orgone therapy is seen as pseudoscience. A m ...

Cloud Seeding
Cloud seeding is a type of weather modification that aims to change the amount or type of precipitation, mitigate hail, or disperse fog. The usual objective is to increase rain or snow, either for its own sake or to prevent precipitation from occurring in days afterward. Cloud seeding is undertaken by dispersing substances into the air that serve as Cloud condensation nuclei, cloud condensation or ice nucleus, ice nuclei. Common agents include silver iodide, potassium iodide, and dry ice, with hygroscopic materials like table salt gaining popularity due to their ability to attract moisture. Techniques vary from static seeding, which encourages ice particle formation in supercooled clouds to increase precipitation, to dynamic seeding, designed to enhance convective cloud development through the release of latent heat. Methods of dispersion include aircraft and ground-based generators, with newer approaches involving Unmanned aerial vehicle, drones delivering electric charges to ...

Acetylene
Acetylene (Chemical nomenclature, systematic name: ethyne) is a chemical compound with the formula and structure . It is a hydrocarbon and the simplest alkyne. This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities such as divinyl sulfide and phosphine.Compressed Gas Association (1995Material Safety and Data Sheet – Acetylene As an alkyne, acetylene is Saturated and unsaturated compounds, unsaturated because its two carbon atoms are Chemical bond, bonded together in a triple bond. The carbon–carbon triple bond places all four atoms in the same straight line, with CCH bond angles of 180°. The triple bond in acetylene results in a high energy content that is released when acetylene is burned. Discovery Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet ...
