Air use not very good at transferring heat. To have effective air cooling you need to pump lots of air. The current ventilation shafts certainly have their limits and especially night time the noise may become an issue if you put serious jet engines there.
- toomuchtodo 9y agoYou'd pipe chilled coolant down into The Tube and perform the heat exchange below ground (cooling the air below). The energy intensive chillers would run on the surface. But first, regenerative braking; you must stop adding more energy into the system before you consider a method to extract the existing thermal energy.
- maxerickson 9y agoThey already use regenerative braking and are running all of their ventilation shafts at full blast all the time (with upgraded fans). The groundwater system in the article more or less does what you suggest, without the expense of the chillers.
