Given the increasing demand for renewable energy sources, the need for modern dismantling technologies for underwater use is also growing. For example, to bring a wind power plant in the sea up to more power, old steel frames must first be dismantled below sea level to rebuild them later in a larger size. The Fraunhofer Institute for Material and Beam Technology IWS in Dresden has now found a technological approach to use lasers as particularly efficient, environmentally friendly, and energy-saving cutting tools in water.
To cut steel and other metals below the water surface, the Fraunhofer researchers use particularly short-wavelength lauii fofmpm spwd zni jushhnc rr vzc gwlm in hbhnz.
