Knowledge engineering techniques are becoming useful and popular components of hybrid integrated systems used to solve complicated practical problems in different fields. Knowledge engineering techniques offer the following features: learning from experience; handling noisy and incomplete data; dealing with non-linear problems; and predicting. This paper presents a knowledge engineering case st...

Nowadays more and more attention is given to energy development problems. Modern ways of producing energy are bounded by planet’s resources of coal, natural gas and petroleum, and harmful effects of waste produced by energy industry forced the increasing growth of alternate ways of energy development, such as wind farms, geothermal and solar energy, etc. The article considers a solution the pro...

Fluorescent nanocrystals are promising candidates for a range of applications, ranging from biomedical imaging and sensing to solar energy conversion and lighting. Recently, these nanometer-sized semiconductor crystals (also referred to as “quantum dots”) have shown potential to be used as novel geothermal reservoir tracer particles. Quantum dots have size-dependent, tunable electronic and opti...

Italy has a strong geothermal potential for power generation, although, at present, the only two geothermal fields being exploited are Larderello-Travale/Radicondoli and Mt. Amiata in the Tyrrhenian pre-Apennine volcanic district of Southern Tuscany. A new target for geothermal exploration and exploitation in Italy is represented by the Southern Tyrrhenian submarine volcanic district, a geologi...

Geothermal energy production In C&Hfomla has been Identified as a major source of arsenic by the California Air Resources Board. New regulations have been Implemented by the State of California, which require Information on ambient levels and emissions of inorganic arsenic. However ,these laws consider only total arsenic and do not lake Into account the potential diHerences In toxicily and perh...

Geothermal energy has been harnessed for recreational uses for millennia, but only for electricity generation for a little over a century. Although geothermal is unique amongst renewables for its baseload and renewable heat provision capabilities, uptake continues to lag far behind that of solar and wind. This is mainly attributable to (i) uncertainties over resource availability in poorly-expl...

Editorial Topic 4 of the Renewable Energy Program of the Helmholtz Association focusses inter alia on the sustainable and cost-efficient use of geothermal reservoirs for base-load supply of heat and electricity by EGS. Current EGS projects show the limitations of such systems. Firstly, the localization of a potential reservoir prior to drilling still remains a major challenge. Secondly, the min...

The exploitation of shallow geothermal energy through a groundwater heat pump (GWHP) is always limited to thick and deep aquifers containing abundant water with a relatively stable temperature. Unfortunately, aquifers in hilly regions which occupy two thirds of China are usually thin and shallow. The boundary conditions in those hilly areas affect the groundwater flow that is used for geotherma...
