A Swiss startup, Borobotics, has introduced an innovative autonomous drill designed to make geothermal energy more accessible for homes and businesses. The compact device, nicknamed the “world’s most powerful worm,” aims to simplify and reduce the cost of tapping into the Earth’s natural heat.
According to a Borobotics co-founder, the drill will enable geothermal energy extraction in previously unimaginable locations, such as small gardens, parking lots, and even basements. This breakthrough could revolutionize how geothermal energy is harnessed for everyday use.
The drill, named “Grabowski” after a famous cartoon mole, measures just 5.3 inches (13.5 centimeters) in diameter and 9 feet (2.8 meters) in length. Its small size allows it to operate efficiently in tight spaces, such as residential backyards. Unlike traditional drills, the Grabowski is fully autonomous, requiring no human intervention during operation.
Equipped with advanced sensors, the drill can identify the materials it encounters underground. If it detects water or gas reservoirs, it can automatically adjust its direction or halt drilling entirely. Additionally, it can seal off potential hazards on its own. Another key feature is its electric power source, which sets it apart from conventional fuel-powered drills.
Despite its advantages, the Grabowski has some limitations. It operates at a slower pace compared to traditional drills and can only reach a maximum depth of 1,640 feet (500 meters). However, Borobotics believes these constraints are manageable for its target market. The company is focusing on shallow geothermal energy rather than deep drilling.
“In many European countries, the average temperature at 250 meters underground is around 14 degrees Celsius,” explained a Borobotics representative. “This makes it ideal for efficient heating in winter and cooling in summer.”
Shallow geothermal systems typically use a network of underground pipes to transfer heat between the ground and surface buildings. These systems are connected to specialized heat pumps, which use the ground’s stable temperature to regulate building temperatures year-round. By leveraging this technology, Borobotics aims to make geothermal energy a practical solution for more households and businesses.
The Grabowski drill represents a significant step forward in making geothermal energy more accessible, particularly in urban and residential settings. While it may not replace traditional deep-drilling methods, its compact design and autonomous capabilities could open new doors for sustainable energy solutions.
