Water Cannons
Tempress Technologies has developed a range of ultra-high-pressure water cannons. Energy is stored in these devices by
compressing water to ultra-high pressure; 30,000 to 40,000 psi (200 to 400 MPa). A
fast-opening valve discharges the compressed-water resulting
in a high-power impulse.
The water slug impact pressures can exceed 800,000 psi (5.5 GPa). The high-power, water jet impulse generated by a water cannon can be used for a variety of mining and construction
applications including non-explosive excavation of hard rock, heavy concrete demolition, foundation soil improvement and soil perforation for environmental
remediation.
