Abstract: A system and method for harnessing geothermal energy using fracturing of hot rock. The system has at least a first well and a second well. The method involves introducing an alkali metal downhole in a first well. A solution is also introduced into the first well. The solution produces an exothermic reaction with the alkali metal. The gas and heat fracture the hot rock producing fractures. The fractures fluidly connects the first well to the second well. A solution, such as water, can be pumped through the first well, through the fractures, and into the second well. The hot rock passes geothermal energy to the water which can then be utilized.

Abstract: An oil production system and method. The system includes a system for heating unrecovered oil. The system includes a chemical injection well having at least one subterranean outlet. The system also includes an oil production well with at least one subterranean inlet. The subterranean outlet is lower in elevation than the at least one inlet. The chemical injection well is coupled to an injected reactant source, and wherein said injected reactant source reacts with a second reactant in an exothermic reaction.

Abstract: A historical marker content transmission unit for transmitting first historical marker content associated with a first historical marker according to an acceptance message sent to the historical content marker request platform and second historical marker content associated with the first historical marker according to predefined parameters selected by the user and stored in a database associated with historical marker content request processing platform.

Abstract: A system and method for a pump. The pump has a pump cover which has an upstream end and a downstream end. An inlet valve is coupled to the pump. An outlet valve is also coupled to the pump. There is an expanding element housed within the pump cover, creating an annulus between the expanding element and the pump cover. The annulus has a volume which can be filled with a fluid. The expanding element has a non-expanded state and an expanded state. The volume of the annulus changes between states of the expanding element. When a pressure is applied to the expanding element, fluid which was drawn into the pump is expelled due to the closing annulus. Therefore, fluid is pumped from the inlet valve through the pump and out of the outlet valve via pressure applied to the expanding element.

Abstract: The tool includes a rotatable shank having a guide member releasably mounted upon its lower portion and adapted to be closely received within the muzzle portion of a gun barrel, and further includes a file member projecting radially outwardly from a medial portion of the shank and rotatable in unison with it. The file member overlies and engages the muzzle end surfaces of the barrel and, upon rotation of the shank of the tool, it "squares" and otherwise finishes such surfaces. The means by which the file member is mounted preferably is of a releasable type that includes a supportive backing member. The extent of the radial projection of the file member from the shank preferably is such that when the tool is used in association with a double-barreled firearm, it simultaneously finishes all of the muzzle end surfaces thereof.

Abstract: Sliding movement of the trigger guard of the firearm controls desired aspects of the operation of its firing and breech-locking mechanisms. Improvements are provided in a firing mechanism of the type that is maintained in a cocked condition by a toggle linkage; and in the breech-mounting, shell-extracting, cocking and breech-locking mechanisms of a firearm of the side-opening type.
