Concentrating sunlight with mirrors is a source of power.

The Viking lenses were capable of concentrating enough sunlight to ignite fires.

Also known as Solar thermal, this technology uses various types of mirrors to concentrate sunlight and produce heat.

For this application, the mirror can be concave, so as to concentrate sunlight onto the cooking vessel.

In industrial cases a parabolic mirror can concentrate sunlight on the tube.

High-temperature collectors concentrate sunlight using mirrors or lenses and are generally used for electric power production.

They get the heat by sun mirrors, concentrating sunlight.

By concentrating sunlight current systems can get better efficiency than simple solar cells.

In many such systems, mirrors are employed to concentrate sunlight into a smaller area.

In the tests, devices concentrate sunlight as much as 60-fold.
