EarthGrid, a San Francisco-based startup, developed plasma tunnel boring technology. Their patented system uses plasma-powered machines that bore through rock by inducing thermal shock resulting in spallation. The post suggests testing channels could potentially resemble Aswan quarry measurements, raising questions about whether such technology patterns could have existed in ancient Egypt or require alternative explanations.
