The hot dry rock geothermal energy program [PDF]

open access: yes, 1987
A description of a geothermal energy project in Fenton Hill, New Mexico, known as the Hot Dry Rock Program was presented. As opposed to common geothermal projects where existing hot ground water is trapped, this project utilized deep holes in dry rock. Two vertical holes were drilled and then connected by hydraulic fracturing. Water was pumped into the

Surface friction of rock in terrestrial and simulated lunar environments [PDF]

open access: yes
The conventional probe-on-the rotating-disk concept was used to determine the surface friction in mineral probe/specimen interfaces. Nine rocks or minerals and two stainless steels were tested in both new (NT) and same track (ST) tests under three ...
