While cooking a hot dog is "a child's play", melting steel is something you must seriously think about.

As you may know, satellite dishes have a focal point (that is a point in which the electromagnetic energy focuses at its maximum power).

The mirrors almost have half the size of a football field, and the whole system is able to focus 1MW of energy into the furnace. Each mirror tracks the Sun's movement and focuses on it, so to get maximum power out of the received light.
