Home > Parabolic trough

A parabolic trough is a type of solar thermal collector. It is constructed as a long parabolic mirror with a Dewar tube running its length at the focal point. Sunlight is reflected by the mirror and concentrated on the Dewar tube. Heat transfer fluid runs through the tube to absorb heat from the concentrated sunlight. It is the most widely used type of solar power. It is usually aligned on a north south axis.

Parabolic microphoneA parabolic microphone uses a parabolic reflector to collect and focus sound waves onto a microphone receiver, in much the same way that a parabolic antenna (e. satellite dish) does with radio waves. Typical uses of this microphone, which has unusually fo	Parabolic reflectorA parabolic reflector (also known as a parabolic dish or a parabolic mirror is a reflective device formed in the shape of a paraboloid of revolution. Parabolic reflectors can either collect or distribute energy such as light, sound, or radio waves.
