1. A method of producing an electrical charge storage structure, comprising the steps of:
(a) using a first laser beam configured to irradiate an encapsulated, sub-surface region of a carbon pre-cursor material below a surface of the carbon pre-cursor material, the parameters of the first laser beam being selected to create carbon foam in that encapsulated, sub-surface region and a carbon-based material above the carbon foam; and
(b) using a second laser beam configured to remove or ablate the carbon-based material sitting above the carbon foam, the parameters of the second laser beam being selected to expose or alter at least some of the carbon foam, to produce a resultant carbon foam material; and
(c) configuring the resultant carbon foam material for use as an electrical charge storage structure.
