In this segment of the video, the narrator discusses the Fibonacci sequence, the golden ratio, and the golden spiral, highlighting their prevalence in nature and potential applications in modern engineering, specifically in turbine design. The Fibonacci sequence, not actually created by Fibonacci from calculating rabbit populations, is explained as a series where each number is the sum of the two preceding numbers. The relationship between the Fibonacci sequence and the golden ratio is explored, with references to the division in extreme and mean ratio as proposed by Plato and Pythagoras. The segment emphasizes the significance of these mathematical concepts in various fields, including architecture, art, music, and potentially in optimizing energy harvesting in turbines.

In this segment of the video, the speaker discusses the concept of the Divine proportion, also known as the golden ratio, which is approximately 1.618. They mention how this ratio was first discovered in the 15th century and had further associations in the 20th century. The discussion delves into the relationship between the golden ratio and the Fibonacci sequence, explaining how the two are closely connected but not exactly the same. Various myths and misconceptions surrounding the golden ratio, such as its supposed use in human body proportions, the Mona Lisa, and ancient structures like the pyramids, are also touched upon. The segment concludes by highlighting that despite the widespread associations with the golden ratio, not all natural spirals are true representations of it, with examples like galaxies and ocean waves being cited as being logarithmic rather than in the golden ratio.

In this segment of the video, the speaker discusses different types of spirals, including logarithmic spirals such as the golden spiral and Archimedes spiral. The importance of these spirals in turbine design is highlighted, with a focus on Fibonacci-inspired turbines. The speaker introduces a small turbine model and promotes a learning platform called Brilliant for understanding mathematics, science, and engineering. The segment concludes with a discussion on Savonius wind turbines, known for their simplicity and reliability in urban environments.

In this part of the video, a team of researchers from Spain is exploring ways to improve the efficiency of turbines. By using blades that follow the Fibonacci spiral instead of the standard curve, they achieved a 14% increase in efficiency with higher power and thrust coefficient. The Fibonacci shape increases the drag force of the advancing blade and reduces the drag force of the returning blade, enhancing the driving force. The video discusses real-world examples of the Fibonacci sequence in nature, such as sunflowers and pine cones. Inspired by these patterns, researchers are exploring the use of the Golden Ratio in designing wind turbines to maximize energy capture.

In this segment of the video, two types of alternative energy turbines are discussed. Firstly, a hydro energy turbine based on the golden spiral design was tested and found to be 15% more efficient at slow water speeds compared to a conventional propeller turbine. This design aims to maximize energy harvest from gentle water flows. Secondly, the Liam F1 Archimedes turbine, based on a logarithmic spiral design, is showcased. This turbine utilizes a spiral shape to harness wind energy through a combination of lift and drag forces, differing from traditional horizontal axis wind turbines. The turbine’s unique design allows it to spin with minimal wind input, showcasing its potential for energy generation in low-wind conditions.
