1MW Solar Powered Laser Made in Uzbekistan

Uzbek researchers want to make a 40-meter tower, tapped with 62 electronically controllable mirrors, arranged in a concave form that focus the Sun's power onto a solar furnace. 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.
