A compressor free, generator free system production well for accelerated oil and gas removal from a reservoir using a magnetically coupled expander pump assembly, which include an outer expansion turbine that rotates around a pump. A magnetic coupling couples the expansion turbine to the pump. An inner portion of the magnetic coupling can be coupled to a pump shaft that drives the pump. An outer portion of the magnetic coupling can be driven by the expansion turbine, which rotates circumferentially around the pump. The expansion turbine drives the fluid to pump a driven fluid stream through the magnetic coupling. In this manner, flow directions of both driving and driven fluid streams remain separate and coaxial, thereby facilitating a reduction in an overall diameter of the expander pump assembly.

Systems and methods for collecting and processing permafrost gases and for cooling permafrost are disclosed herein. A method for processing gas in a permafrost region includes obtaining a gas from a sacrificial area of a thawing permafrost region, dissociating the gas in a non-combustive chemical process, and circulating a constituent of the gas through a savable area of the thawing permafrost region to cool the savable area. This process can be used to cool selected areas of permafrost and/or create clean-burning fuels and/or other products from permafrost gases.

According to one embodiment, a circulatory osmotic pressure electricity generation system configured to generate electricity by using a working medium, which includes an osmotic pressure generator, a turbine, a tank, a separating tower, a heat source and the working medium. The working medium has a critical temperature which separates a first temperature zone and a second temperature zone from each other and has a phase transition to a first phase or a second phase which occurs at the critical temperature. The osmotic pressure generator is placed under a temperature of the working medium within the first temperature zone, and comprises (i) a container, (ii) an osmosis membrane, (iii) a first inlet, (iv) a second inlet, and (v) an outlet.
摘要:
A power generation system in which a thermally expandable fluid, e.g., R134a, CO2, is circulated in a loop between a first location and a second location, the second location being at a higher elevation than the first location. The fluid is heated at the first location to expand it, so that it rises to the second location where it is cooled and contracted. The cooled fluid, being denser, then falls back to the first location under hydrostatic pressure, causing a circular fluid flow. This flow is used to generate power in a power transfer system. The system is regulated so that the fluid does not flash to a vapor, i.e., the fluid does not change state, which improves the efficiency of the system. The system is suitable for use in any situation where a height difference exists, and is particularly suited for geothermal heating sources.
