Abstract: Systems and methods are disclosed for storing energy and generating power and/or heat within a subsea environment. The systems and methods utilize stored compressed air within an air storage chamber to drive an engine/generator system in order to generate power. The engine may or may not utilize combustion. Alternatively, the systems and methods utilize stored compressed air to supply air to a combustor to generate heat. The heat generated can be used for variety of purposes, including to generate steam and to heat heavy oil.

Abstract: A vacuum system is disclosed for reducing heat loss within the annular chamber of a steam injection well. The apparatus includes elements for drawing vapor within the annular chamber outside the well, elements for condensing the vapor and elements for discharging the fluid. In addition, the apparatus incorporates elements to isolate and bypass the vacuum and condensing means in the event of high-steam leakage that may damage any components thereof.

Abstract: Hitherto, efficient combined solar heating and passive cooling has not been available in a convenient, modular, relatively simple to install, reasonably priced apparatus. A reservoir (12) has a cover (32) having upper (42) and lower (44) reflective surfaces. Liquid (26) fills the reservoir (12) to a desired level (28). The cover (46) is positionable in either closing relation over the open top (24) of the reservoir (12) with the upper surface (42) reflecting sunlight away from the reservoir (12) or in open relation with the lower surface (44) aligned generally to reflect sunlight towards liquid (26). A normally floating raft (68) substantially covers the top surface (30) of the liquid (26) to retard cool weather daytime evaporation and other heat losses from the liquid (26). The raft (68) may be removed at night during warm weather to provide efficient evaporative and radiative cooling.
