Passive Cooling and Energy: 5 Biomimicry Examples
Termite mounds, silver ants, pinecones — nature's zero-energy approaches to thermal management. All examples use zero active energy input.
Passive cooling — managing temperature without mechanical refrigeration — is one of biomimicry’s most commercially promising areas. As global temperatures rise and energy costs increase, technologies that cool buildings and surfaces for free are attracting serious investment. Nature has been doing this for millions of years.
