Powerful laser
One of the most powerful lasers is used in geothermal energy. It has an output power of 30,000 watts. Laser beams used in industry are more than ten times less powerful with output powers ranging between 2,000 and 3,000 watts. These lasers are used to weld and liquefy steel. In geothermal drilling, the laser beams loosen the crystals in the stone. This creates cracks in the rock. The porous material can then be broken more easily and quickly with a mechanical drill.
