Have tested different materials for galvanic air battery and found that magnesium and graphite most efficient ones, so just glued magnesium chips and thin graphite slices to business cards with dry cotton layer between, got dry "business card" size bttry cells, three of which able to run pulse motor and LED on secondary coil; yes, have to actuated the cell by adding couple drops of water to layer, but dry it can be stored for years...
