abstract="When a building is on fire, the building may be dark because of a power failure or heavy smoke. In this case, the people inside the building may lose their sense of direction and may possibly become trapped in the building. Although there may be some emergency lights and indicators located at specific corners of the building, they may not be adequate to direct the occupants to a safe place, or they may be inoperative because of a failure of the emergency devices. In this study, laser scattering and energy harvesting technology, integrated with automatic sprinklers, is proposed to solve the problem of fire evacuation when there are inadequate or faulty emergency lights or indicators. When the automatic sprinklers are activated by the fire, the water flows through micro-turbine generators attached to the sprinklers, which generate electricity that is used to supply power to the illumination system. The illumination system uses a laser projector with a holographic pattern to project evacuation signs and highlight exit locations. It is believed that with this technology, the possibility of survival and the chance for rescue are increased. The energy harvesting technology proposed in this study has another innovative benefit in that no battery or utility wire is needed.<p />",
