Scientists have found two main ways to conduct cloud seeding. The second method is to use a cloud-seeding device called a balloon. A balloon is inflated with a mixture of water vapor and sulfuric acid. This mist is then blown up to a height of several hundred feet. It is this mist that is used to seep clouds into thunderstorms.

How much does it cost to seed a cloud?
In ideal conditions, seeding increased winter precipitation by up to 15 percent. A cloud seeding program in the region could cost between $27 to $214 per acre-foot of water in a low cost scenario and between $43 to $427 per square foot in an expensive scenario. The study was funded by the National Science Foundation, the U.S. Army Corps of Engineers and the Department of Energy.
What are the side effects of cloud seeding?
To analyze the amount of silver in the snow, samples can be collected and sent to the labs. Silver iodide is a naturally occurring element that is found in the earth’s crust. It is used as an additive in many industrial processes, such as the production of silver nitrate and silver sulfide, as well as in a variety of consumer products, including toothpaste, deodorants, cosmetics, and food additives.
(EPA) regulates the use of iodides as a pesticide, but does not regulate their use in cloud-seeding applications. EPA does, however, require that the application be conducted in accordance with the National Aeronautics and Space Administration’s (NASA’s) National Environmental Policy Act (NEPA), which requires that all research and development activities be carried out in an environmentally responsible manner.

What material is used to seed clouds?
Dri uses a compound called silver iodide (agi) to help in the formation of ice crystals. Silver iodide can be found in the environment at low concentrations and is not known to be harmful to humans or animals. AgI to coat the surface of the clouds with a thin layer of silver, which is then blown into the cloud.
As a result, the silver-coated cloud is able to remain in place for longer periods of time than if it were not coated with silver. In addition, silver can act as a catalyst for the release of other chemicals, such as carbon dioxide and water vapour, that would otherwise be trapped in a cloud’s updraft.
How long does it take to seed a cloud?
Depending on the seeding delivery method, the seeding effects can range from almost immediate to 30 minutes. The cloud will remain in place for a period of several days, but will eventually dissipate. In contrast, base-seeding is a method in which cloud particles are released from a cloud base, usually at altitudes of 100 km or more, and then spread out over a wide area.
Is cloud seeding safe for the environment?
The most common chemical used to seed clouds is known to be toxic and is regulated by the Clean Water Act and the Toxic Substances Control Act. TSCA is a federal law that regulates the use of toxic chemicals in the United States. EPA has also stated that the process is safe and does not pose a threat to human health or the environment.
Does cloud seeding stop hail?
States, cloud seeding is used to increase precipitation in areas experiencing drought, to reduce the size of hailstones that form in thunderstorms, and to reduce the amount of snowfall that falls on the ground. (NOAA) and the U.S. Department of Agriculture’s (USDA) National Agricultural Statistics Service (NASS) are the primary agencies responsible for collecting and disseminating weather data.
(NCDC) collects data on precipitation, temperature, humidity, wind speed and direction, sea surface temperature (SST), and sea level pressure.
How toxic is silver iodide?
The silver ion is among the most toxic of heavy metal ions, particularly to microorganisms and to fish. Ag is less important as an environmental contaminant because of the ease with which it forms insoluble compounds. Ag is not likely to focus on harmful levels in the aquatic environment. Ag is a major component of the earth’s crust.
Is silver iodide addictive?
It’s basically a dangerous drug. In addition to being a bleach and an explosion, it is extremely addictive. The short, but powerful, high of silver iodide is offered in concentrated doses. The drug is also extremely toxic to the liver, causing liver failure and liver cancer. It can also cause kidney failure, which can lead to death if not treated quickly.
The drug has also been linked to a number of other serious health problems, such as heart attacks, strokes, and strokes of the blood vessels in the brain and spinal cord, as well as liver and kidney damage, according to an article in The New York Times.
