Abstract
A solar-powered light source may comprise a solar-powered energy production module. The solar-powered light source may be self-righting. At least one of the energy production module, an energy storage module, a light emission device, or a diffuser may provide the weight for the self-righting effect. The weight may be located substantially near a bottom portion of the solar-powered light source in order to keep the solar-powered light source positioned upright.
