本报告描述了一种新的方法，能量转换为动能，用于从混合物的膨胀产生电力，通过热盐水沉积物中储存的能量。缩放喷嘴高的三种形式的地热能，速度输出是用来驱动一个修改的热盐水资源具有最大的水力脉冲涡轮机运行潜力的发展一个可行的长-3.5英寸。Hg（120 'F）。从理论上讲，地热能供应范围广。这是一个这种方法应该产生60%以上的大型能源与回收和电力比其他系统，无论是operconversion只需要适度extional或建议，为热盐水紧张局势的现有技术的基本优势是，建议的方法是开发-d使用，允许回收专门应用于盐水的能量在液体中，否则，索尔顿海地热区，哪里会迷路。使用水力不足够的能量被存储以提供脉冲涡轮机概念是有吸引力的，因为至少100，000 MW发电所需的大部分技术存在，容量超过20年。这些设备本身是坚固的，并且可以用耐腐蚀-侵蚀材料制造。我们估计，采用这一概念的发电站将资本投资约200美元/千瓦，在电力销售价格为8米尔斯/千瓦时的成本下，肯定是一个较低的成本，我们估计内部回报率在10%到2070年之间，这取决于税收方法，3包含约20%的蒸汽特许权使用费。
This report describes a new method energy is converted to kinetic energy by for producing electrical power from the expansion of the mixture through a energy stored in hot brine deposits. converging-diverging nozzle. The high the three forms of geothermal energy, velocity output is used to drive a modithe hot brine resource has the greatest fied hydraulic impulse turbine operating potential for development of a viable longat -3.5 in. Hg (120'F). Theoretically, range geothermal energy supply. It is a this method should produce 60% more large energy source with recovery and power than other systems, either operaconversion requiring only moderate extional or proposed, for the hot brine tensions of existing technologies The basic advantage is that The proposed method is develope-d is used, allowing recovery specifically for application to the brines of energy in the-liquid that otherwise , of the Salton Sea geothermal area, where would be lost. The use of hydraulic imenough energy is stored to provide at pulse turbine concepts is attractive since least 100,000 MW electrical generation much of the needed technology exists, the capacity for more than 20 yr. These devices are inherently rugged, and fabrication with corrosion-erosion resistant materials is possible. We estimate that an electrical power neration station using this concept will capital investment of -$200/kW ill certainly be a ower at a cost of power sales price of 8 mills/kWh, we estimate the internal rate of return to be between 10% and 2070, depending on the method of taxation and 3 contains ~ 2 0 % vapor by v royalty charges.
