In , 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 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. The truck itself looks a bit like a heavy lunar rover. At the front a closed cabin for the operator, in the middle the vibration plate and hydraulics, at the back the diesel engine and pumps. Some parts are covered for noise insulation, but most parts are clearly visible and open. 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.
