Neopentyl glycol can be used for thermal energy storage by virtue of its soHd-phase transition, which occurs at 39—41°C, a temperate range useful for solar heating and cooling (28—31). 

Aragonite. Calcium carbonate is a common deposit in shallow tropical waters as a constituent of muds, or in the upper part of coral reefs where it precipitates from carbon dioxide-rich waters supersaturated with carbonate from intense biological photosynthesis and solar heating. Deposits of ooHtic aragonite, CaCO, extending over 250,000 km in water less than 5 m deep ate mined for industrial purposes in the Bahamas for export to the United States (19). 

Relative humidity, percent = 50 Wind velocity, mi/h = 5 Dry-bulb air temperature, °F = 68 Solar heat gain, Btu/(h-ft ) = 100 Water quantity, gal/min = 10,000... 

The effect of solar radiation must be considered in the outdoor part of a bus enclosure exposed to solar heat. This effect ma be observed for all LT and HT bus enclosures, as all are influenced equally by such radiations, particularly IPB enclosures, as discussed in Section. 3 1.4.4. 

Does your house have air conditioning, or a heat pump Do you have solar he,- ig, a Jacu22i bath, swimming pool, aquarium, solar heating, a roof mounted water storage tank, a well, a power assisted commode, a motorboat, a jet ski, ATV or camper Then you have even more mechanical sealed pumps. We have mechanical sealed pumps in practically all facets of our everyday life, and these pump seals last for years wii problems. 

Another applieation for turboexpanders is in power reeovery from various heat sourees utilizing the Rankine eyele. The heat sourees presently being eonsidered for large seale power plants inelude geothermal and oeean-thermal energy, while small systems are direeted at solar heat, waste heat from reaetor proeesses, gas turbine exhaust and many other industrial waste heat sourees. Some of these systems are diseussed below in greater detail. 

Much attention is also being given to solar energy. It does not appear that direct solar heat is economically feasible as a large power plant energy source however, this resource has great potential for a number of process and heating applications. 

One form of solar heat does offer interesting possibilities and is refeiTcd to as OTEC (Ocean-Thermal Energy Conversion). The OTEC power plant principle uses the solar heat of ocean surface water to vaporize ammonia as a working fluid in a Rankine cycle. After the fluid is expanded in the turbine, it is condensed by the 22°C colder...

The distribution of solar radiation, including surface radiation exchange, can account for solar heat source variations in time and local space.
