- The MTA is exploring geothermal technology to cool subway platforms by moving heat deeper underground.
- Target stations include the 1 line's 168th Street and 181st Street stations, known for being particularly hot due to their depth.
- Underground subways have multiple heat sources, including electronics, air conditioning units, and train car systems.
- The proposed cooling technology aims to maintain platform temperatures between 82-85°F on hot days for deep stations.
- Installation requires extensive work, such as sending pipes deep underground.
- Current cooling methods like street vents are ineffective for deep stations.
- The MTA is considering storing excess heat in the ground if it can't be released outdoors.
- Some newer stations already use 'air tempering' systems with fans and dehumidifiers.
- Riders have complained about extreme heat and broken air conditioning, especially on the 1 line.
