## Summary

Hosts Daniel and Forbode discuss three distinct engineering innovations: an artificial electronic nose from Karlsruhe Institute of Technology (KIT) that uses quartz crystal microbalance sensors and machine learning to distinguish mint types for pharmaceutical applications; a wastewater-to-energy system by Professor Zhen He at Washington University in St. Louis that generates electricity and filters water using microbial fuel cells with carbon cloth anodes; and a satellite-based index insurance model from ETH Zurich that uses real-time soil moisture data to automatically payout farmers during droughts.
