Petra is a deep-tech developer of tunneling robots intended to efficiently and safely bore utility conduits through any geology. The company's technology will be faster and cost less than conventional tunneling methods, thereby enabling industries to make small-diameter utility infrastructure economically viable. By easily, quickly, and cost-effectively burying all utilities, Petra allows existing cities to move their utilities underground -- a current cost, safety, and technology prohibitive option -- removing the life and property risk in the Western U.S. as a result of urban wildfires caused by above-ground utilities.
