Abstract: Highly radioactive material is permanently disposed of by first forming a borehole by a metal fusion drilling method with a metal lining from a casting continuously formed from a metal melt and then depositing the highly radioactive material for final storage in a lower area of the lined borehole. This lining is melted locally immediately above this lower area after deposition of the material to separate the lower area holding the material from the rest of the lining and permit this lower area and the material held therein to migrate automatically downward toward the center of the earth. To promote this downward migration, the wall thickness of the metallic lining of the lower borehole region has a wall thickness that increases from the top downward and on the lower area is formed with a downwardly directed conical tip.

Abstract: A method and system are disclosed for recovering fossil fuel from a carbon deposit site, the method comprising (a) driving several boreholes through the earth's crust to depths below the surface at which supercritical conditions predominate, so that they are spaced from one another in a lower borehole region, and connected there to one another through to form a geo-heat exchanger resulting in creation of a supercritical geo-steam system; (b) injecting fluid into at least one of the boreholes, to convert the injected fluid into a supercritical fluid, and extracting the supercritical fluid through other of the boreholes; and (c) injecting the extracted supercritical fluid into the carbon deposit site to dissolve hydrocarbons contained therein, and transporting the supercritical fluid containing the hydrocarbons to the surface for recovery.

Abstract: The invention relates to a method for fusion drilling and to a fusion drilling device for producing dimensionally accurate bores, manholes rock and tunnels in the ground, particularly in rock. A drill hole bottom is molten by a melt and the overburden melt is pressed into the surroundings, particularly the surrounding rock which has cracked open under the effects of the temperature and pressure, and wherein during drilling, a drill hole lagging (9) is produced around piping formed by line elements (1, 2, 3). In a recess (5) of at least one lower line element (1) of the piping, said recess being particularly centric and open towards the top, metal (7) in a solid state of aggregation is fed from the top thereof, particularly through line elements (2, 3) arranged on the top thereof.

Abstract: Disclosed are a method and a device for utilizing supercritical subsurface steam as combined supercritical thermal and hydraulic power stations at an efficiency of 50 percent, using molten bath superdeep drilling technology, a hydrofrac process, and the special properties of the supercritical subsurface steam, such as the drastic increase in the thermal capacity, reduced viscosity, and inorganic solubility. The multifunctional use of said technologies and physical properties of supercritical subsurface steam in the inventive method allows a supercritical subsurface boiler to be tapped rapidly and at a low cost at a great depth while making it possible to produce electricity, power, process steam, and heat almost anywhere at one tenth of the cost of conventional fuel technologies and comparable expenses.

Abstract: The invention relates to a procedure and device for the use of SC(supercritical)-GeoSteam for a possible complete exploitation of coal- and hydrocarbon deposits, preferably insitu, by means of “SC-GeoSteam Injection” well as the use of CO2 as the element for CO2 resource management within a closed system, with the necessary primary energy harvested in the form of SC-GeoSteam from a Supercritical Subsurface Boiler (SSB), also called a Geo heat exchanger, by means of super-deep drilled mine shafts. The SSB as the primary energy provider for SC-GeoSteam Injection can, at the same time, be used as a natural SCW* reactor. Because of the low viscosity of SC-GeoSteam and its high solubility in hydrocarbon, the hydrocarbons dissolve 100% in the supercritical fluid and are catalyzed in the presence of catalysts into high-grade hydrocarbons which can be separated via simple pressure reduction without complicated refining methods.

Abstract: In order to provide a method with apparatuses for safe final storage of highly radioactive waste products while safely coping with a reactor core melt, and final storage of the highly radioactive as well as slightly radioactive and medium-radioactive inventory when dismantling the nuclear power station itself in situ, it is proposed that a metal-shell drilled shaft composed of a casting be used as the final storage shaft at the nuclear power station location to which the material to be finally stored is supplied via a bomb-proof transport tunnel, which is hermetically isolated from the biosphere, from the reactor building or temporary stored by means of a magnetic sliding trans-port system for introduction to store, with filled final store sections migrating into the earth's mantel after separation from the remaining shaft, with residual heat being produced and under the influence of the force of gravity.

Abstract: A fusion drilling process and device for the placement of dimensionally accurate borings, particularly those of large diameter, in rock, in which the waste melt is pressed into the surrounding rock, which is cracked due to the effect of temperature and pressure, and in which a borehole lining is produced by solidifying melting during boring, with a melt containing metal supplied through pipeline elements as a boring medium to the base of the borehole to be removed through melting. For this purpose a melt made of magnetic metal is preferably used.

Abstract: The invention relates to a method for actuating nonsystem-connected vehicles by means of high-temperature accumulators and for the operation of stationary energy storage using material with high evaporation enthalpy as storage media for high-temperature heat. Said high-temperature heat is generated by means of current transfer and can be stored for a sufficient length of time by means of super isolation and high-temperature resistant carbon materials. On demand, the stored high-temperature heat can be converted directly into electric operating energy, specifically pressure energy, for actuating hydraulic motors by means of a thermionic generator or a Stirling motor.

Abstract: The hot-weak-rock process for overcoming the technical limitation inherent to the Hot-Dry-Rock Process, of not being able to overcome the shear strength of the rock beyond a certain depth in order to create heating surfaces through HYDRAFRAC. The hot-weak-rock process creates a heating zone in an area of the continental lithosphere in which the shear strength of the hot rock suddenly decreases with increasing overburden and the HYDRFRAC necessary to create heating surfaces is effectuated under the hydrostatic pressure of a water column in a correspondingly deep and lined boring. A technically easily generated additional pressure component is applied to the water column in the boring to create the initial cracks in the lower, unlined section of the boring.

Abstract: Only a gap defining the outer profile of the tunnel or borehole is melted down in a peripheral heat drilling process for tunnels, deep-well and exploration boreholes. The drill core, surrounded by the generated gap, initially remains and is then extracted at intervals via a tube. It is expedient for the drill core to be sheared off and extracted continuously after it has passed a cooling zone. The height of the drill core, which first remains in the borehole, is determined such that the molten rock can be pressed into the drill core, whereby the necessary pressure for this pressing in is maintained essentially constant, independently of the depth of the borehole concerned.

Abstract: A high pressure pipe string for continuous fusion drilling of deep wells which houses supply lines, measurement instrumentation and control wiring of the drilling device. It has at least two shell elements forming two halves of a pipe, and these parts are assembled into a smooth, tight, and compression and tension resistant pipe. In a process for assembling, propelling and subsequently dismantling a high-pressure pipe string for continuous fusion drilling of deep wells, the supply lines, the measurement instrumentation and the control wiring are fed to the boring head in a continuous manner. The supply lines, the measurement instrumentation and the control wiring are encased in a tight, compression and tension resistant high-pressure pipe string having several parts, the assembled pipe string being continuously propelled downward into the boring. The device for the execution of one of these processes has one storage carrousel for each of the supply lines, on which the supply lines are wound.
