Cryogenics is the study of the production and behaviour of materials at extremely low temperatures. It is used in a variety of applications, including cryogenic engineering and cryobiology.

At low temperatures, materials exhibit a range of unusual properties, including superconductivity, superfluidity and reduced friction. These properties make cryogenics an important tool in a variety of scientific and engineering disciplines.

Cryogenic engineering is the field of engineering that deals with the design and construction of equipment and systems that operate at extremely low temperatures. This includes the study of the behaviour of materials at low temperatures, the design of cryogenic engines and the development of cryogenic storage methods.

Cryobiology is the study of the effects of low temperatures on living organisms. It is used to understand the effects of cryogenic conditions on the human body, as well as to develop methods for cryogenic preservation of tissue and organs.

How cold is cryogenic freezing?

Cryogenic freezing is the process of cooling an object to a very low temperature, typically -196°C. This is done using a specialised cryogenic chamber, filled with a liquid coolant such as nitrogen or helium. The object to be frozen is placed inside the chamber, and the coolant is circulated around it until the desired temperature is reached.

The main advantage of cryogenic freezing is that it can preserve the object for a very long time, without the need for constant refrigeration. This makes it ideal for applications where long-term storage is required, such as for medical samples or archaeological artefacts.

How much does it cost to cryonics?

The cost of cryonics varies depending on the specific procedure and the provider, but it typically ranges from $30,000 to $200,000. Some providers offer discounts for pre-payment or for signing up for multiple procedures, and many insurance policies cover at least a portion of the costs. What is cryogenics for humans? Cryogenics for humans is the science of using extremely cold temperatures to preserve human tissue. This can be done by freezing the tissue, or by using cryoprotective chemicals to prevent ice formation. Cryogenics is used for a number of medical applications, including organ transplantation, fertility preservation, and cancer treatment. It is also used in cryonics, which is the practice of storing human bodies at very low temperatures in the hope of revived them in the future.

How many people are cryogenically frozen?

There is no definitive answer to this question as it largely depends on the definition of "cryogenically frozen." If we consider cryogenic freezing to simply refer to the process of cooling a body to very low temperatures in order to preserve it, then the answer would be difficult to determine as there is no centralized registry of individuals who have undergone this procedure. However, if we consider cryogenic freezing to refer specifically to the process of freezing a body with the intention of reviving it at a later date, then the answer is much more clear.

As of March 2019, there are only four companies in the world that offer whole-body cryogenic freezing services: Alcor Life Extension Foundation, Cryonics Institute, KrioRus, and Suspended Animation, Inc. According to Alcor, they have cryogenically frozen 1,099 people as of December 2018, while Cryonics Institute reports that they have cryogenically frozen 2,262 people as of July 2018. KrioRus does not publicly disclose the number of people they have cryogenically frozen, but according to their website, they have performed over 1,000 cryopreservations since their founding in 2005. Suspended Animation, Inc. has only performed two whole-body cryopreservations as of March 2019.

In addition to these four companies, there are a number of individuals who have elected to cryogenically freeze themselves without the help of any organization. It is difficult to estimate how
