The sunflower has found optimal space utilization for its seed head by packing of the seeds by arranging them in spirals of Fibonacci numbers. This ensures that the seeds will always be packed uniformly, and with maximum compactness. This has been researched to be used in solar power technology to reduce the required amount of land while boosting the amount of sunlight the heliostat mirrors collect.
In addition sunflowers turn throughout the day, always following the path of the sun to ensure maximum solar collection.
