Geothermal Drilling. Reinvented.

Discover the future of geothermal drilling


Heating from the earth

Our earth stores near infinite reserves of energy. Yet, only 1% of Swiss households use geothermal energy for heating. We aim to push forward the energy revolution and establish geothermal energy as a viable and cost-effective source of heating.

Grabowski is a 2.5 m by 135 mm tube that replaces the massive 6 m tall and

10 t heavy drills that are currently used. All in all, Grabowski requires 6-8 m2 of space and can thus drill in any garden, parking garage or even basement.

Grabowski operates completely autonomous - it is simply installed and deinstalled at the drill site. While it drills, it tracks its every movement and steers itself downwards in a straight trajectory.

Gentle on the earth

Grabowski does not require any of the diesel-consuming equipment that conventional drills use such as compressors. Instead of consuming 700l of diesel per borehole, it simply plugs into an electricity outlet.
