Claim 0:
1. An elevator system comprising:
an elevator cabin within a wind turbine;
a traction wire rope for vertically driving the elevator cabin;
a traveling power cable providing a power source to the elevator cabin;
a housing unit installed in the elevator cabin, the housing unit containing a supercapacitor, an electronic circuit, and at least one light source, wherein the electronic circuit distributes energy received from the traveling power cable to power the at least one light source, and charge the supercapacitor using any remaining energy; and
a control system configured to control how the electronic circuit distributes the energy between the light source and the supercapacitor, the distribution based on whether the energy satisfies an energy threshold,
wherein, when the energy received from the traveling power cable is insufficient to power the at least one light source, the electronic circuit draws energy from the charged supercapacitor to power the at least one light source for a period of time to allow sufficient power to be received from the power source to power the at least one light source.
