Heating, electricity and transportation are the three components of urban systems final energy consumption. Geothermal energy and biomass are two promising renewable energy resources that can be used for the production of heat, electricity and biofuels, thus allowing a reduction of fossil fuel consumption and of the associated greenhouse gas emissions. The goal of this paper is to assess the po...
BACKGROUND The combination of seawater baths and narrowband ultraviolet B (NB-UVB) is a known treatment for psoriasis. This study evaluates two treatment regimens that combine bathing in geothermal seawater and NB-UVB therapy in comparison with NB-UVB monotherapy. METHODS Sixty-eight psoriasis patients were randomly assigned to outpatient bathing in geothermal seawater combined with NB-UVB th...
Perfect compatibility between geothermal plants and the development of the other resources of the territory (tourism, quality agriculture, etc.) is a key issue for the sustainability of the geothermal energy and its acceptance by the communities hosting the plants. Third Millennium geothermal projects are able to win this challenge. Integration in the landscape of power plants and related infra...
The geochemical energy sources for microbial primary productivity in the >70°C geothermal springs of Yellowstone National Park have not been understood. Results from phylogenetic studies of geothermal communities indicate, unexpectedly, that hydrogen-metabolizing organisms, both known and novel, dominate these communities. Hydrogen (H2) is the basis of diverse microbial metabolisms, yet little ...
Urban systems account for about two-thirds of global primary energy consumption and energy-related greenhouse gas emissions, with a projected increasing trend. Deep geothermal energy and woody biomass can be used for the production of heat, electricity and biofuels, thus constituting a renewable alternative to fossil fuels for all end-uses in cities: heating, cooling, electricity and mobility. ...
Heterogeneous hydrologic, lithologic, and geologic basal boundary conditions can exert strong control on the evolution, stability, and sea level contribution of marine ice sheets. Geothermal flux is one of the most dynamically critical ice sheet boundary conditions but is extremely difficult to constrain at the scale required to understand and predict the behavior of rapidly changing glaciers. ...
Recent national focus on the value of increasing US supplies of indigenous renewable energy underscores the need for re-evaluating all alternatives, particularly those that are large and well distributed nationally. A panel was assembled in September 2005 to evaluate the technical and economic feasibility of geothermal becoming a major supplier of primary energy for US base-load generation capa...
BACKGROUND Geothermal waters contain, among other components, soluble radon gas. Alpha radioactive radon is a health hazard to humans, especially when it gets into the respiratory tract. SPA facilities that use geothermal water can be a source of an increased radiation dose to people who stay there. Based on the available literature concerning radon concentrations, we assessed exposure to radon...
In NE Iceland there are ample geothermal resources both high temperature and low temperature geothermal fields as well as boiling low-temperature or medium enthalpy resources. It is of utmost importance not to waste the energy even where the resources are ample and cascade use of the energy is desirable. Many of the high-temperature fields in the area are now being harnessed for electricity pro...
