As the liquid turns to gaseous nitrogen at around -196 C, [The Action Lab] figured that it could be used to propel a simple steam engine at room temperature. Testing this out had amusing results.

Dr Vijay HS further explained that liquid nitrogen has two properties which can cause problems for a person's health. "First is the temperature itself, which is around -190 to -200 degrees Celsius.

Today, these applications all require liquid nitrogen or liquid helium. If future room-temperature superconductors end up having high critical current densities as well, you could cheaply build ...

Scientists in the United States have created a testing platform for energy harvesting in solar-plus-storage systems under ...

Nitrogen makes up about 78% of the Earth's atmosphere. Liquid nitrogen is very cold, so it is often used to freeze food. The boiling point of nitrogen is −196 °C, so liquid nitrogen is very ...
