There is something fishy going on in the Hagerbach Test Gallery, deep in the Glarus Alps in Switzerland. Today the former iron mine is a place of invention, where new underground technologies are explored, tried and tested. In one of the 80m caverns two tanks of Rainbow Trout swim around, unaware that their waste products are providing critical nutrients for an array of leafy vegetables and herbs that are growing in hydroponic beds. 

In this episode we talk to Swiss Centre of Applied Underground Technologies (SCAUT) Managing Director Klaus Wachter to find out how tunnels could become homes to farms of the future. And we explore other projects that are opening up the world beneath us.
