This is a bee smoker, which, unlike others, needs no external power source, instead of this, it uses the thermal energy generated by the fuel which produces the smoke (for the thermic-electric transformation it uses ThermoElectricGenerators).
-No external energy source needed
-Built in rechargeable battery- for lighting the fuel
-<3mm holes covering the fan- no bees can be harmed
-It has no black colored parts- so the bees wont charge if they see it.
