213. Dehumidifying Walls Help Switzerland Hit Net Zero By 2050

The Next Byte Podcast · 4 Mar 2025 · 17m

What this episode covers

The hosts discuss research from ETH Zurich on dehumidifying walls made from marble waste and geopolymer binders, designed to passively absorb humidity and reduce energy consumption in buildings. They analyze the binder jet 3D printing process used to create the porous macro-structure and critique the scalability of this manufacturing method for large-scale construction. The conversation covers simulation results showing significant comfort improvements, potential carbon payback periods, and the structural challenges of retrofitting such materials into existing European and American building frameworks.

    Literally unearthing a climate solution with Cody Finke of Brimstone

    Cody Finke, co-founder and CEO of Brimstone, explains how his company is decarbonizing cement production by replacing limestone with calcium silicate rocks like basalt. He details the chemical process that eliminates process emissions and creates a magnesium byproduct that passively sequesters CO2, making the material carbon-negative. Finke discusses the strategic pivot from developing novel materials to producing ordinary Portland cement to ensure rapid adoption by the construction industry, and outlines the path from lab validation to pilot plants and eventual commercial scaling.

    Transforming Cooling Systems for Energy Efficiency and Global Impact with Ross Bonner

    Ross Bonner, CTO and co-founder of Transaera, explains how his company uses metal-organic frameworks (MOFs) to create air conditioning systems that use 40% less energy than conventional units by decoupling dehumidification from cooling. Bonner details the transition from GE Aerospace to MIT, where he and co-founders Serene Gnanamanickam and Mirchadinka combined 15 years of MOF research with a focus on HVAC efficiency to address the global equity crisis in cooling access. The team developed a desiccant wheel architecture that integrates with standard rooftop HVAC equipment, allowing for rapid adoption by manufacturers without requiring new installation processes. They are currently validating the technology through commercial pilot programs, aiming to scale production as MOF manufacturing costs decrease to eventually serve underserved markets in hot, humid regions.
