What would happen if you combined the unparalleled efficiency of a superconductor with the flexibility and controllability of ...

Scientists successfully control the direction of current in a superconductor, creating a superconducting diode.

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.

Then the diode was known as a "valve," because it forced current in the tube to travel exclusively in one direction. Getting that single directional flow was critical for radio sets which needed ...

This directional behavior is analogous to the way an electronic diode facilitates unidirectional current flow based on the ..

The diode has a very high resistance in one direction. This means that current can only flow in the other direction. This is the graph of current against voltage for a diode. Normally a diode will ...
