San Francisco-based startup Earthgrid is developing a plasma boring robot that is capable of digging tunnels 100 times faster, and up to 98 percent cheaper than existing boring systems, a report from New Atlas reveals.
The company plans to use its technology to rewire energy, internet, and utility grids in the U.S.
Unlike conventional boring machines, which typically use massive cutting wheels to slowly excavate tunnels, Earthgrid's robot blasts rocks with high temperatures to break and even vaporize them via a process called spallation.
The machine can run on electricity, meaning it can also be emissions-free, depending on how energy is sourced. Earthgrid also claims that its system, which doesn't need to come into contact with the rocks directly as it excavates, is so fast and cheap it will open up a whole host of possibilities.
In other words, projects that were once deemed economically unfeasible will now be possible.
