Abstract
An exhaust device includes a housing, a drive unit, and an electric generator. The housing includes a tubular wall with a tube axis, and a mounting wall transverse to the tube axis. The tubular wall has an inlet end portion to be connected to a source of exhaust gas. The housing is formed with a vent for discharging the exhaust gas. The drive unit includes a drive shaft disposed in the housing, and an impeller connected to the drive shaft such that the exhaust gas received from the source can drive rotation of the drive shaft. The electric generator includes a stator mounted on the mounting wall, and a rotor coupled to the drive shaft such that the rotor is rotatable with the drive shaft relative to the stator to generate electricity for operating a load, such as a lamp unit.
