The rolled up metallized paper capacitor configuration or paper-spaced metal-foil rolls
in D2O Electrolyte cans would be a way to get the high interface fields with or without a few volts
or so applied between the "plates".
The wicking action of paper (or fiberglass) can draw the electrolyte several inches against gravity
allowing the roll to rest on it's side in the can.without need for large amounts of D2O.
Based on Szpak's paper, it would be interesting to see if such a device would self-heat
without an applied voltage.
