Root Energy found that Korea's clean-power bottleneck was not the turbine or the solar panel. It was consent - so the company made nearby residents investors, built a regulated climate-finance platform around the idea, and added an RE100 business for corporate buyers.
Aeromine Technologies builds a motionless, bladeless rooftop wind energy system for commercial and industrial buildings. Its 10-foot units sit along a roof's edge and use vertical airfoils to capture and amplify a building's own airflow, generating electricity silently and without spinning blades. The company says the system can produce up to 50% more energy than a comparable rooftop solar array while using roughly 10% of the roof space, and it is designed to complement, not replace, solar. Founded in 2021 and headquartered in Houston, Aeromine has run pilots with BASF and BMW Group and raised a ~$9M Series A led by Veriten in 2024.
