Electrolysis is the reverse process of a Fuel Cell.

By connecting electric power onto the 2 cylindrical metal elements the cup acts as an electrolysis unit, and by connecting the JouleThief onto the 2 metal elements the unit acts as a Fuel Cell.

First electricity is introduced into the unit (cup of salt water), than electricity is provided by the same unit.
