In #Munich, you might see (and hear, feel) this weird machine, making weird vibration and sound sweeps. This is part of the Giga-M project. Its goal is to create a detailed 3D map of the underground in Munich and surrounding areas (in total 1100 square kilometres) that will be made available as #OpenData to assist in planning geothermic plants. Switching away from fossil fuel for heating. Impressive!

A so-called Vibro Truck. A heavy metal plate is lowered to the ground and a vibration sweep is initiated. Thousands of probes are distributed all over the city that receive these sweeps, allowing to create a detailed 3D map of the underground, showing potential hot water streams that can be used for geothermics.

@jwildeboer As long as it is shallow well geothermal! The deeper stuff may yeild more "steam power", but it does so at a higher cost that has yet to be calculated - employ the right technologies to decarbonize! 👍🤞✊

@decapitae I am living close to a rather big deep geothermic installation that is up and running since 20+ years and goes 3000 metres deep (Riem). Munich has a total of 6 in operations. See swm.de/unternehmen/geothermie (German)

Geothermie in München und der Region Die SWM sind einer der führenden deutschen Experten für die Tiefengeothermie und verfügen über jahrelange Erfahrung. Unsere erste Geothermie-Anlage ging 2004 in Riem in Betrieb: Sie ist bis heute ein Vorbildprojekt. Aktuell betreiben wir sechs Geothermieanlagen, weitere kommen hinzu.
