Interferometric synthetic aperture radar (InSAR) data collected in the Coso geothermal area, eastern California, during 1993-1999 indicate ground subsidence over a ,-•50 km •' region that approximately coincides with the production area of the Coso geothermal plant. The maximum subsidence rate in the peak of the anomaly is •3.5 crn yr -•, and the average volumetric rate of subsidence is of the ...

A Monte-Carlo Simulation using Excel Spreadsheet has been used to determine the reliability of a geothermal power plant. This simulation technique utilizes the powerful mathematical and statistical capabilities of Excel. Simulation time is dependent on the complexity of the system, computer speed and the accuracy desired, so a simulation may range from a few minutes to a few hours.

Background: Small capacity, low temperature, geothermal heat sources provide significant opportunities for distributed, small scale power generation. Project definitions and pre-dimensioning however require advanced thermodynamic engineering at a cost independent of project size. In order to reduce this cost, a new method has been developed to allow basic level engineers to perform pre-optimisa...

Thermus thermophilus TMY (JCM 10668) was isolated from silica scale formed at a geothermal power plant in Japan. Here, we report the complete genome sequence for this strain, which contains a chromosomal DNA of 2,121,526 bp with 2,500 predicted genes and a pTMY plasmid of 19,139 bp, with 28 predicted genes.

The use of geothermal energy and its associated technologies has been increasing worldwide. However, there has been little paradigmatic research conducted in this area. This paper proposes a systematic methodology to research the development trends for the sustainable development of geothermal energy. A novel data analysis system was created to research the geothermal energy utilization trends,...

Geothermal energy has many advantages over solar and other renewables. These advantages include: 1) weather-proof; 2) base-load power; 3) high stability and reliability with a capacity factor over 90% in many cases; 4) less land usage and less ecological effect; 5) high thermal efficiency. The total installed capacity of geothermal electricity, however, is much smaller than those of solar energ...

Siliceous scaling potential of geothermal brines has long been an obstacle to the efficient energy recovery from some geothermal resources. In classical flash geosteam plant the brine for disposal was separated at high enough temperature in order to avoid ((silica oversaturation)) which might lead to scaling on hiher cooling for additional power generation through heat recovery. Recent years bi...
