## Summary

Paul Gross, Co-founder and Co-CEO of Remora, explains how his company retrofits semi-trucks with a device that captures at least 80% of CO2 emissions directly from the tailpipe. Gross details the engineering challenges of adapting carbon capture technology for mobile use, including managing variable exhaust conditions and minimizing weight to avoid reducing payload capacity. He outlines the business model, which involves selling the hardware to partners like Ryder and splitting revenue from the sale of captured carbon credits, while also discussing the potential for carbon-negative operations when paired with biofuels.
