20120153772 | METHOD AND DEVICE FOR GENERATING ELECTRICITY AND METHOD OF FABRICATION THEREOF - Particulated structures and their method of manufacture for use in an electrical generator employing gas-mediated charge transfer are disclosed. The structures comprise a multiplicity of particles which contain voids between first and second opposing surfaces of said particles. At least a portion of said opposing surfaces are modified such that the charge transferability of said first opposing surfaces differs from the charge transferability of said second opposing surfaces. | 06-21-2012 |
