The company has debuted its Plasma Excavation System (PES) featuring two plasma torches in a step forward in the viability, efficiency and capabilities of the TBR.
The TBR successfully excavated 40 cubic meters, creating a 10-foot by 12-foot tunnel through greywacke in 30 hours using a single torch. Moreover, the TBR has been used successfully to tunnel through granite, quartzite and basalt – some of the most challenging rock geologies in the world.
EarthGrid has unveiled the successful development and deployment of its proprietary two-torch PES, paving the way for combining additional torches to its TBR, and increasing the speed and efficiency of its operations.
Troy Helming, CEO and Founder of EarthGrid, said:
“These two developments illustrate a clear step in proving our TBR model and its potential to rapidly connect our underground electrical and fiber optic grid safely. No company has ever tried boring through rock with more than one plasma torch – much less through rock like greywacke or granite. We are excited to deploy our two-torch system on several upcoming customer projects.”
