Soil nailing
Soil nailing is a geotechnical construction method that reinforces in-place soil with steel bars drilled and grouted into a slope or excavation face, stabilizing cuts built from the top down.
Soil stabilization
Soil stabilization is a geotechnical method that improves the strength and durability of weak soils by blending soil gradations or mixing in additives like lime, cement, fly ash, or bitumen.
Soil–structure interaction analysis
Soil–structure interaction (SSI) analysis is an engineering method modeling how soil deformation and stiffness modify a structure's seismic response, using direct or substructure methods, notably for nuclear power plants.
Solar chimney
A solar chimney heats air with sunlight so it rises through a vertical channel, ventilating a building or, at large scale, driving turbines to generate electricity.
Solar still
A solar still, a form of solar distillation, is a device that purifies saline or contaminated water using only sunlight, collecting condensed vapor as fresh water.
Solar water disinfection
Solar water disinfection (SODIS) is a household water treatment method in which contaminated water in transparent PET bottles is exposed to sunlight for at least 6 hours, inactivating pathogens.
