Germans build mega-station without AC, then explain why. Online mockery erupts: 'Genius...'

Deutsche Bahn's explanation for omitting air conditioning from the new Stuttgart 21 underground train station has sparked widespread ridicule online. The railway company released a video asserting that the station's subterranean placement will naturally regulate temperatures, eliminating the need for artificial cooling.

Because the station will only be finished by the next ice age. Smart.

René Krull, from the Stuttgart 21 technical project management, explained that building elements will absorb the surrounding earth's temperature, maintaining a constant internal climate. He further elaborated that the station's position at the lowest point of the Stuttgart basin, with tunnels gradually ascending, would cause incoming air to cool and descend, further aiding temperature control. Train movements themselves are also expected to contribute to air circulation.

My great-great-great-grandchildren will surely enjoy the pleasant temperatures when they finally open it.

However, this technical justification has failed to convince many social media users. Comments ranged from sarcastic remarks about the station opening during the next ice age to questions about how the system would handle heat generated by trains. Critics also pointed to the ongoing delays and cost escalations of the Stuttgart 21 project, which has already seen its completion date pushed back to 2031, adding a layer of irony to the air conditioning debate.

Due to this, the building elements adopt the temperature of the subsoil, and the massive construction in combination with the location in the ground allows the temperature inside to remain relatively constant.
