300‑500% efficiency, groundwater at 10‑15 °C year‑round → open‑loop geothermal cooling cheap vs standard AC. Catch: Minnesota outlawed new installs in 2015. Verify address‑level permits before you dig. The physics is solid; the regulatory maze isn’t. Could smart permitting frameworks unlock this low‑grade heat resource without wrecking aquifers? #GreenTechnology #CleanWater #EnergySaving #EcoTech
