Provided here is an architectural plan (the solution) for the restoration of the terminal lake, the Salton Sea, an area of prevalent geothermal sources. It includes division of the Lake into three sections, preventing pollution of the Lake from nearby farmlands and importing seawater in central section with pipeline system; providing condition for tourism, and wildlife sanctuary; generating electricity by harnessing hydro, solar, and geothermal energy; and producing potable water and lithium as byproducts. Also includes a system and method for harnessing geothermal energy for generation of electricity by using complete closed loop heat exchange systems combined with onboard drilling apparatus. The system includes several devices operating separately in many different applications in energy sectors, Also, included is alternative use for the In-Line-Pump for marine crafts propulsion.
