The Appropriateness of Snowmobiling in National Parks: An Investigation of the Meanings of Snowmobiling Experiences in Yellowstone National Park
The debate over snowmobiling and other types of motorized recreation in US national parks signals the need for a better understanding of the meanings of these experiences. The fundamental issue facing many parks is whether snowmobiling is an appropriate activity. The matter of appropriateness is anchored in two questions: (1) Does snowmobiling in national parks cause unacceptable biophysical and ...

Direct Air Capture - Let`s reverse climate change!
The Swiss company Climeworks fights the climate change and removes carbon dioxide from the air by capturing it and storing it safely and permanently underground. It is not a futuristic vision from another planet - this is happening now in Iceland. It might seem futuristic or like images from another planet, but it is real and the Direct Air Capture plant in Iceland, where the geothermal ...

CETCO TC Booster used on Blatchford Dess Energy Centre #1 - Edmonton Municipal Airport Geothermal Project - Case Study
In May 2018, a drilling contractor started the installation of 570 (6” diameter x 500ft deep) geothermal boreholes in Edmonton, AB, Canada. The project at the former Edmonton Municipal Airport started with 2-rigs drilling in a formation of clay, silt, and coal seams. It increased to multiple rigs before the successful completion in October 2018. The grout development started prior to the ...

Feasibility investigation of coupling a desalination prototype functioning by Aero-Evapo-Condensation with solar units
The rural regions of south Mediterranean countries suffer from problems of drinking water supply. However, the majority of these regions have important resources of brackish salt water. Thus, brackish water desalination on a small scale presents a potential solution to this problem. For this reason, a number of small desalination prototypes are being developed worldwide. Bourouni et al. have ...

Geodrilling: Managing Water Supply in Italy
In recent years there has been significant reorganisation in the Italian water sector to conform to the rules set out in the European Union Water Directive concerning the control of water pollution and the consistency of water tariffs. There have been some successes, particularly where companies in the industrial and commercial sectors, who manage their own water supplies, have had some ...

H2S Emissions Control at Geothermal Plants
The LO-CAT® II process is used to control H2S emissions and reduce odors at geothermal power plants. Geothermal steam, considered to be a clean and environmentally friendly source of energy, is produced when water seeps into high temperature, high pressure formations below the earth's surface. The steam is brought to the surface through production wells and then expanded through a ...

CO
2hydrates as a climate change mitigation strategy: definition of stability zones in the Portuguese deep offshoreStorage of CO2 as hydrates in sub–seabed sediments has been indicated as an alternative solution for the geological storage of CO2, suitable for offshore areas where large ocean depths and low temperatures exist at short distance from the shore. This paper presents the works conducted to identify the CO2 hydrates stability zone, i.e., the areas where CO2 hydrates may form and remain stable, in ...

Physical, chemical, bacteriological and radioisotopic parameters from springs and wells around Jocotitlan volcano, Mexico
Samples from seven springs and two wells around Jocotitlan volcano (Mexico), mainly used as drinking water supplies, were studied for physical, chemical, bacteriological and radioisotopic parameters. The temperature of the majority of the water was 5°C higher than the average atmospheric temperature of the zone, indicating a geothermal potential. The water type was bicarbonated mixed, related to ...

Efficiency of a Biodegradable Antiscalant against Barite under Geothermal Plant Conditions
In geothermal power plants, various types of scales can occur. Barite (BaSO4, barium sulfate) is the dominating mineral species of the scales in a region in middle Europe, acting as isolation material and leading to a reduction of the heat transfer and clogging of installations. Further, sulphide minerals like galena (PbS, lead sulfide) may be part of the scaling. As a consequence, cleaning for ...
