Richard,
	Nature also contains some materials that are conductive and won't leach
into the water. Platinum at first comes to mind but its
very expensive. Platinum is used in electrolysis and sublimation of
many chemicals including Sodium Flouride for Flourine production.
	A better choice that is easily available in micron sheets
and is economical enough to work with is gold leaf. If the sheets
where attached to a rigid surface for support. A workable water
capacitor might be obtained. 
	For example, wrap the gold leaf around both sides of a
plexiglass sheet and wedge the sheets into a plexiglass spacer 
assembly. The spacer assembly could also be the containment vessel. 
Then fill with deionized water and seal.

Just some incomplete ideas.
Flames welcome.
