By storing excess electrical energy that is generated by the dynamo in a capacitor, and getting the spring to unwind only when the capacitor charge falls below a certain threshold, it has proved possible to extend the playing time of the second-generation radio to about an hour.

ECONOMIST: Clockwork technology

The better the insulator, the more charge a capacitor can hold.

ECONOMIST: Combinatorial chemistry

Engineers had learned that a resistor, which restricts the flow of electrical current, is best made of certain materials and a capacitor, which stores electrical charge, of others.
