Generating Ions from Liquids
31:12 - 42:52 (11:39)
Scientists have discovered that they can generate jets of ions from liquid by applying a strong electric field to stresses the liquid, causing a cone to form at the tip that generates a jet of ions. By providing the liquid with a support, the electric field can be focused on the tip, requiring less voltage to create the field.

Summary
By putting a liquid into an electric field a jet of ions can be generated from the tip of that liquid. The electric field pressure pulling on the ions balances the liquid's own restoring force, its surface tension.

Researchers build thruster chips by manufacturing hundreds or thousands of sharp structures and then applying voltage to create a strong electric field that focuses on the tip, allowing the tiny cone to form on top, and finally, supplying the liquid to the tips.
