A turbine that has a runner with attached blades similar to a propeller used to drive a ship. As water passes over the curved propeller blades, it causes rotation of the shaft.

An interior or exterior movable panel that operates on hinges or slides into place, used to protect windows or provide privacy.

The quantity of heat that a cooling appliance is capable of removing from a room in one hour.

Pounds/force per square inch absolute.

A construction element applied to the outermost surface of an exterior wall.

A solar power station investigated by NASA that entailed a satellite in geosynchronous orbit that would consist of a very large array of solar photovoltaic modules that would convert solar generated electricity to microwaves and beam them to a fixed point ...

A coating applied to the surface of the glazing of a window to reduce heat transfer through the window.

Thermal energy that is used in agricultural and industrial operations.

A chemical element, of atomic number 14, that is semi-metallic, and an excellent semiconductor material used in solar photovoltaic devices; commonly found in sand.

A commonly used analysis for reporting fuel properties; may be on a dry (moisture free) basis, as "fired", or on an ash and moisture free basis. Fractions usually reported include: volatile matter, fixed carbon, moisture, ash, and heating value (higher he ...

A general term applied to the energy that is converted to a form that can not be effectively used (lost) during the operation of an energy producing, conducting, or consuming system.

A steady-state fermentation process.

The difference between the brightness of an object compared to that of its immediate background.

A method of financial and economic analysis used to determine present and future values of investments or expenses.

A type of insulation that is molded or expanded to produce coarse, closed cells containing air. The rigid cellular structure provides thermal and acoustical insulation, strength with low weight, and coverage with few heat loss paths. Often used to insulat ...

A solar thermal technology that uses a modular mirror system that approximates a parabola and incorporates two-axis tracking to focus the sunlight onto receivers located at the focal point of each dish. The mirror system typically is made from a number of ...

An electromechanical device composed of a coil of wire wound around a cylinder containing a bar or plunger, that when a current is applied to the coil, the electromotive force causes the plunger to move; a series of coils or wires used to produce a magnet ...

The use of solar thermal energy or solar electricity to power a cooling appliance. There are five basic types of solar cooling technologies: absorption cooling, which can use solar thermal energy to vaporize the refrigerant; desiccant cooling, which can u ...

That amount of cooling energy to be supplied (or heat and humidity removed) based on the sensible and latent loads.

Usually refers to ethanol to 160 to 200 proof.
