Pyreliophorus

The Pyreliophorus was a device similar to a burning glass, created by the Portuguese priest Manuel António Gomes, also known as padre Himalaya, whose objective was to melt many different types of materials using solar energy.

[1] The device used several reflecting mirrors to concentrate the sunlight into a common point.

With this device, it was possible to reach a temperature of around 3500 °C, enough to melt many types of metals and rocks.

[2] Unlike a common burning glass, the Pyreliophorus uses a concentric parabolic array of mirrors to concentrate the sun light into a common point, instead of a lens.

The device uses a clock system that makes the mirror array concentric axis to rotate along the sun alignment.
