Abstract: Various examples of methods and systems are provided for increasing productivity of one or more photosynthetic cultures via self-powered light systems. In one example, a system includes a waterproof casing and a light module enclosed within the waterproof casing. The waterproof casing is configured to be neutrally buoyant in a culture tank comprising the one or more photosynthetic cultures. In another example, a method includes placing a self-powered light system within a culture tank, the self-powered light system being neutrally buoyant within the culture tank. The method further includes causing turbulence of water within the culture tank, and the self-powered light system harvests energy to power a light of the self-powered light system via the turbulence of the water within the culture tank.
