Convection plays a role in thermionic emissions by enhancing heat transfer, which can improve the efficiency of thermionic devices. One application is in thermionic converters, where convection helps maintain optimal temperature gradients for electron emission. Additionally, convection can be utilized in cooling systems for thermionic emitters to prevent overheating. Lastly, convection can influence the design of thermal management systems in space applications, where thermionic devices may be used for power generation.
The wave pendulum was first demonstrated by Richard Berg in the 1980s. It consists of an array of swinging pendulums that transfer kinetic energy in a wave-like pattern, creating mesmerizing visual patterns.
It was invented by neutrogena in 2008...... I think.

The term "thermionic value" typically refers to the thermionic emission, which is the release of electrons from a material when it is heated to high temperatures. This phenomenon is significant in various applications, including vacuum tubes and certain types of electron sources. The thermionic value can be influenced by factors such as temperature and the material's work function, affecting the efficiency of electron emission.
A thermionic thermometer is a device that measures temperature by detecting the electrons emitted from a heated surface. It relies on the thermionic emission phenomenon, where electrons are released from a heated cathode and collected at an anode to generate a measurable signal related to the temperature of the cathode.
