Making Liquid Oxygen: Far From Easy but Worth the Effort
1 min read
Summary
YouTuber Shahriar has created a liquid oxygen distillation plant using a pressure swing adsorption oxygen concentrator and a Stirling cycle cryocooler usually found in a superconducting RF filter.
He harvests the Cryocooler to cool the oxygen down to a liquid, using a test stand with forced air cooling and a manifold to supply a constant oxygen flow.
The diodes are used to monitor the temperature at the cold end of the cryocooler and once powered, the cryocooler attains a temperature in the 77 Kelvin range.
This enables Shahriar to produce at least a hundred milliliters of liquid oxygen within an hour that passes all his tests.
This is the first time liquid oxygen has been made in this way and is an interesting use for what is normally a superconducting RF component.
