A diode allows current to travel in only one direction. With that in mind, [Alex] built a mechanical diode that will only allow gear rotation in one direction to be transmitted through the system.

Thermal diodes, much like their electrical counterparts, provide unidirectional heat transfer, allowing heat to flow in one ...

This one-way electric flow, known as rectification, directly reflects the chirality of the material and could serve as a way ...

Which way does electricity flow through ... Things get complicated when reading schematic diagrams involving diodes and transistors that direct the flow of current. Most schematics are drawn ...
