Abstract
A self-powered display system has a display module with a housing comprising sidewalls and having a display panel comprising signage. An array of light emitting diodes is in the housing. A battery powers the light emitting diodes. A wind generator can also be provided to charge the battery. The wind generator comprises a generator enclosure, a wind turbine in the enclosure to receive an external air flow, and an electrical generator rotor connected to the wind turbine to generate electrical power to charge the battery. In one version, the wind turbine comprises a hollow hub and blades extending radially outward from the hub, with the electrical generator in the hub.
