Not a Moonshot, A Mindshift | Lindsey Hermes | TEDxStLouisWomen

Quick Overview

Lindsey Hermes argues that addressing seemingly small, overlooked issues in infrastructure and industry, like using plant-based materials for road maintenance, can lead to massive, scalable positive impacts, such as significantly cutting concrete-related CO2 emissions and improving safety, thereby shifting focus from large, flashy projects to essential, sustainable solutions.

Key Points: The speaker advocates for focusing on 'small solutions' like plant-based asphalt additives instead of only seeking 'big solutions' for existential problems like climate change. An anecdote about her father's accidental discovery in 1994—a plant-based compound that dissolved asphalt but not petroleum-based grime—led to the development of biodegradable detergents and sustainable infrastructure solutions. Asphalt is the most recycled material in the US, but its production is responsible for 8% of global CO2 emissions, highlighting the need for change. The speaker's father's invention, based on soybean oil, successfully replaced petroleum-based grime cleaners and extended pavement life, saving maintenance budgets and emissions. Research shows that preserving existing infrastructure, like roads, is far more cost-effective and environmentally friendly than full replacement; for instance, preserving one mile of road costs about $10 compared to $167,000 for full reconstruction. The core message is a 'mindshift' away from just building new things (replacement) toward maintaining and preserving what already exists, which is often invisible but crucial for efficiency and sustainability.

Context: Lindsey Hermes presents at TEDxStLouisWomen, framing her talk around the concept that significant global problems, like climate change, can be addressed through overlooked, small-scale innovations rather than only massive 'moonshots.' She uses the personal story of her father, a career scientist who worked on sustainable chemistry in his makeshift lab, as the central example of how small discoveries can yield large, scalable societal benefits, particularly in infrastructure and environmental impact.
