No, these are actually chemical batteries that generate electricity from the chemical interaction of plates and electrolyte. The "electrolyte" is paper rubbed with manganese dioxide or a similar chemical. Their downfall is that the internal resistance is measured in megohms so the available current is a few microamps at most.
Here's a link to the best known example:
1840 Electric Bell Still Ringing... Note that that's a British "billion" - or a thousand times the US "billion." The bell has thus rung some 10,000 million times... and damn, no one's answered it yet.
Capacitors don't generate any electricity, just store whatever charge you apply until it's drained. Hmm, a 100,000 uF, 50V electrolytic...
hee hee hee... CATCH!
