We coat our algae growth chambers with a propriety thin film. The film is able to filter the sunlight such that only targeted wavelengths of light within the visible spectrum can pass through at 100% transmittance. Our lab-scale tests have shown that algae oil output can be modulated by the wavelengths of light that the algae are grown under. The films completely block UV and IR light, which promotes the overall growth of our algae and reduces unwanted heating in our greenhouses. We therefore produce more algae and save on energy usage.
