Plasma Thermal Spallation Contactless Rock Boring Model

Underwrite 10,000°C high-enthalpy plasma arc torches fracturing ultra-hard crystalline granite and basalt via micro-thermal shock spallation without mechanical bit wear (achieving 50 meters/day drilling speeds at 10km super-deep geothermal depths). Model deep borehole excavation contracts ($2,800/meter drilled), and 15-yr IRR.
