A heat exchange device for stabilizing the ambient temperature in large spaces is provided. The heat exchange device comprises an inner tube and an outer tube of rigid material. The outer tube is open at its upper part and closed at its lower part, with a diameter approximately sixty percent greater than the diameter of the inner tube and a length of more than ten meters. The inner tube is also open at its upper part and closed at its lower part, and the perimeter of its lower side has a series of holes. The inner tube is inserted into the outer tube and it has several clamps, which have at least three symmetrical legs located in the perpendicular plane of the axes of the tubes and ending in their respective wheels on free axes. In the upper part of the inner tube an air extractor device is located.

A ladder-structural gravity-assisted-heat-pipe geothermal energy recovery system without liquid-accumulation effect, comprises a ladder-structural gravity-assisted heat pipe, a condenser, and a liquid tank. The ladder-structural gravity-assisted heat pipe comprises a return pipe, an outer pipe and an inner pipe. The return pipe is provided in a space between the outer pipe and the inner pipe and communicated with the liquid tank, and the space between the outer pipe and the inner pipe is divided to form a ladder structure. A liquid working medium flows from the liquid tank through the return pipe into each section sequentially, absorbs heat from a high-temperature rock through a wall of the outer pipe, vaporizes into a gaseous working medium, gets into the inner pipe, and rises to the condenser to condense and flows to the liquid tank to circulate. Such design greatly improves the heat transfer efficiency in geothermal energy recovery using ultra-long heat pipes.

Provided here is a system and method for harnessing geothermal energy for generation of electricity by using complete closed loop heat exchange systems combined with onboard drilling apparatus. The system includes several devices operating separately in many different applications in energy sectors, including Self Contained In-Ground Geothermal Generator; the Self Contained Heat Exchanger; the In-Line-Pump/Generator; and preeminent drilling system for drilling wider and deeper wellbores. The system can be used for harnessing heat from accessible lava flows; harnessing the waste heat from the flame on top of flares stacks and similar cases. Also, included is an architectural solution for the restoration of the terminal lake, the Salton Sea, an area of prevalent geothermal sources, including dividing lake in three sections and importing seawater in central section with pipeline system; providing condition for tourism; treating farmland runoff waters; generating electricity including solar energy; and producing potable water and lithium as byproducts.

A method and arrangement for conditioning a building space of a building includes extracting heat energy from the building space to heat pump working fluid with a primary heat exchange connection of a heat pump and releasing heat energy from the heat pump working fluid with a secondary heat exchange connection of the heat pump to geothermal working fluid of a geothermal heat exchanger. The method further includes releasing heat energy from the geothermal working fluid to ground at lower part of the ground hole having depth at least 300 meters, producing solar energy with a solar energy apparatus provided to the building, and supplying the solar energy to the heat pump or to the geothermal heat exchanger.

Connectors may be used for connecting case settings in high temperature wells, such as geothermal or oil wells. The connector is simple in design and is able to take up thermal expansion due to temperature change when high temperature media starts to flow through the casings and when the well needs to be cooled down for maintenance.
