Certain example embodiments of this invention relate to articles including anticondensation coatings that are exposed to an external environment, and / or methods of making the same. In certain example embodiments, the anticondensation coatings may be survivable in an outside environment. The coatings also may have a sufficiently low sheet resistance and hemispherical emissivity such that the glass surface is more likely to retain heat from the interior area, thereby reducing (and sometimes completely eliminating) the presence condensation thereon. The articles of certain example embodiments may be, for example, skylights, vehicle windows or windshields, IG units, VIG units, refrigerator / freezer doors, and / or the like.

A well treating composition containing a polysaccharide-based water-superabsorbent material has particularly applicability as a thermal insulating, fracturing or acid stimulation fluid. The water-superabsorbent material is capable of absorbing, at a minimum, its own weight. Particularly effective are biodegradable materials containing guar gum and carrageenan. The composition may further contain a crosslinking agent, brine and / or a viscosifying polymer or a gelling agent. As an oil-based fluid, the crosslinking agent is absorbed onto the water-superabsorbent material and serves to effectively delay crosslinking.

Providing: quickly brining a vapor cell 119 to a desired temperature when retaining the heat of the vapor cell 119 to enhance the magnetic field detection performance of an optically pumped magnetometer; preventing adherence of atoms in the vapor cell 119 to a laser irradiation light passing-through part of the vapor cell 119; downsizing the periphery of the vapor cell 119; and suppressing the effect of a magnetic field from a heater used to retain the heat of the vapor cell 119. The present invention includes: a transparent film heater 118 provided to a laser irradiation light passing-through part of a vapor cell 119, the vapor cell 119 being a magnetic detection part of the optically pumped magnetometer; a temperature detector 115 provided at a center part of a side of the vapor cell 119; a temperature regulator 111 that sets a desired temperature for heat retention of the vapor cell 119 and compares the desired temperature and the actual temperature of the vapor cell measured by the temperature detector 115; an operation unit 112 that upon receipt of a PID control signal for temperature control from the temperature regulator 111, performs a temperature adjustment and switches on / off, in a pulsed manner, current applied to the transparent film heater 118 after the desired temperature is reached; and a heater power supply 113 that upon receipt of an operation signal from the operation unit 112, applies current to the transparent film heater 118.

A portable floating hot tub that is easy to assemble and take down and can be used in environments with extremely cold and turbulent water. The hot tub has three main components: a collapsible frame made of connected rigid members, an insulated liner sized and shaped to closely fit against the deployed frame and form a subassembly, and an inflatable pontoon that may have a central aperture for receiving the subassembly. The pontoon is first inflated and placed on the body of water, after which the frame and liner subassembly are placed over the central aperture. Filling the internal volume defined by the insulated liner with water causes the subassembly to descend within the pontoon. Cooperating means on the subassembly and / or pontoon prevent the subassembly from passing completely through the central aperture. A source of heated water such as a portable heater having a heating capacity of at least 30,000 BTUs rapidly heats up the water within the hot tub. The system components can be transported in one or more carry bags of less than 100 pounds and deployed and taken down by one person in an extremely small space, such as on a boat.

A method of conserving energy during a heating event wherein a coolant is heated in a cooling system is disclosed. The method includes establishing a first set point temperature for a first point in the cooling system and establishing a second set point temperature lower than the first set point temperature for a second point in the cooling system. Normally, the coolant is maintained at the second set point temperature at the second set point in the cooling system. During the heating event, the second set point temperature is raised to substantially match the first set point temperature to reduce necessary heating of the coolant at the first point.
