The problem isn’t so much finding uses for the heat, it’s getting the heat out of the tunnels to begin with.
These are some of the deepest tunnels going under some of the most built up parts of the UK.
- BJones12 1y agoI wonder if an extremely tall subterranean windcatcher [0] with its bottom at the top of a tunnel could passively cool the tunnel. [0] https://en.wikipedia.org/wiki/Windcatcher https://en.wikipedia.org/wiki/Windcatcher
- avianlyric 1y agoThese basically already exist around the network. But that simply isn’t even close to moving enough energy to make a difference.
- Full_Clark 1y agoThe catch here is the cost of the buildings you'd need to destroy in order to build the surface portion of the windcatcher. The deep underground lines run under heavily populated areas of London. To build enough windcatchers to move the needle on tunnel temps, you'd need to buy many plots in one of the most expensive cities in the world.
