Now, the application of this technology has been extend to ground, and the solar simulator has been popular with people as the controllable source in laboratory.

Hydro energy for the production of electricity is the next most efficient energy source (after nuclear) and has advantages over direct wind systems in being storable and controllable.

With its controllable solidifying velocity and vast raw material source, cement-water glass(CS)two-shot grouting has found wide applications in many geotechnical projects.
