Niigata's Geothermal Snow-Melting System: A Clever Solution
2025-03-09
Facing heavy snowfall, Niigata, Japan, developed a clever snow-melting system in the 1960s called 'shosetsu'. This system uses geothermal heat to warm groundwater, which is then pumped through pipes under roads and sprayed onto the asphalt to prevent snow from freezing. Niigata currently has approximately 571 kilometers of roads equipped with this system, offering a more environmentally friendly and car-friendly alternative to traditional salting methods.
