Wired to a battery— to run the coil of the dynamo/magneto.... “continuous” power for as long as the battery lasts. When drained... it’s over with.
An “outside source of energy” within the system, which also loses energy within the moving parts.
This is this asian/indonesian guy with the glue gun— who is actually quite good at producing more efficient mouse traps— using a system known to American country/rural/mountain folk: the water bucket baited rolling bar with climbing ramps. Kills dozens a night mice— rats bigger tend to fill the bucket up to where they can jump out and not drown.
