Has any one heard of a diac? 
(While we are components)

I ran across one years ago.

Ummm, no.  Tantalum caps are NOT suitable for low-ESR applications.  A
"solid" capacitor is one that uses a polymer-film electrolyte
replacement (MUCH more expensive to manufacture--more processing
steps).  The relation of a "solid" capacitor to an electrolytic
capacitor is (much simplified) the relation of a lithium-polymer
battery to a Li-ion battery.
