21Water heating — is a thermodynamic process using an energy source to heat water above its initial temperature. Typical domestic uses of hot water are for cooking, cleaning, bathing, and space heating. In industry, both hot water and water heated to steam have… …
22Molten carbonate fuel cell — Scheme of a molten carbonate fuel cell Molten carbonate fuel cells (MCFCs) are high temperature fuel cells, that operate at temperatures of 600°C and above. Molten carbonate fuel cells (MCFCs) are currently being developed for natural gas, biogas …
23Landslide mitigation — Landslides can be triggered by many often concomitant causes. In addition to shallow erosion or reduction of shear strength caused by seasonal rainfall, causes triggered by anthropic activities such as adding excessive weight above the slope,… …
