Sharks Might Save Us Fuel, If We Let Them

Forbes - Apr 26th, 2025

Delta Air Lines is exploring innovative biomimicry by testing a 'shark skin' coating on some of its Boeing 767 aircraft to reduce drag and improve fuel efficiency by up to 4%. This partnership with Australian company MicroTau involves applying microscopic grooves, or 'riblets', to the fuselage, mimicking the natural design of shark skin. The immediate impact includes potential significant reductions in emissions and fuel costs, translating to millions in savings across the fleet. Additionally, Delta is experimenting with finlets, inspired by fish fins, on its 737s to further reduce drag.

This development is part of a broader trend of using nature-inspired solutions to address human challenges. However, it raises concerns about the ongoing threats to shark populations, as these creatures face pressures from overfishing, habitat destruction, and climate change. The potential loss of sharks could mean losing access to efficient biological designs that have evolved over millions of years. This highlights the importance of preserving biodiversity, as the loss of these natural blueprints could hinder future technological advancements in sustainable design.

Fair Story

Consider it well-founded

The article provides an informative and engaging exploration of the potential benefits of biomimicry in aviation, specifically the use of shark skin-inspired technology to improve fuel efficiency. It effectively communicates complex scientific concepts in a way that is accessible to a general audience and highlights the broader environmental context. However, the article would benefit from greater transparency in source attribution and a more balanced exploration of potential challenges and controversies. Overall, it is a well-written piece that raises important questions about the intersection of technology and conservation.

Accuracy

The story accurately describes the structure and function of shark skin, specifically the role of dermal denticles in reducing drag, which aligns with scientific understanding. The claim that Delta Air Lines is testing a 'shark skin' coating to improve fuel efficiency by up to 4% is supported by industry reports, although the exact efficiency gain might vary depending on specific conditions. The article also correctly notes the broader context of biomimicry, citing examples like Velcro and bullet trains. However, while the ecological impacts of declining shark populations are mentioned, the article could benefit from more specific data or studies to support these claims. Overall, the story presents a well-researched account but would benefit from additional source citations to enhance verifiability.

Balance

The article presents a balanced view of the potential benefits of biomimicry in aviation, particularly the use of shark skin-inspired technology, while also highlighting the ecological concerns related to declining shark populations. However, it primarily focuses on the positive aspects of the technology and does not explore potential drawbacks or challenges in implementation, such as cost or technical feasibility. The inclusion of viewpoints from environmentalists or industry experts could have provided a more comprehensive perspective on the issue.

Clarity

The article is well-written and easy to understand, with a logical flow and clear presentation of information. It effectively explains complex concepts, such as the structure of shark skin and the principles of biomimicry, in a way that is accessible to a general audience. The tone is neutral and informative, maintaining a balance between scientific explanation and broader environmental concerns. Overall, the clarity of the article is a significant strength.

Source quality

The article does not explicitly cite its sources, which makes it difficult to assess the credibility and reliability of the information presented. While the content appears to be well-researched, the lack of direct attribution to specific studies, experts, or industry reports limits the ability to evaluate the authority of the information. Including quotes from experts or references to specific scientific studies would strengthen the article's credibility.

Transparency

The article lacks transparency in terms of source attribution and methodology. It does not disclose the sources of its information or provide details on how the claims were verified. Additionally, there is no discussion of potential conflicts of interest, such as partnerships between airlines and technology developers. Greater transparency in these areas would enhance the reader's understanding of the basis for the article's claims and the factors influencing its impartiality.
