GREIFSWALD, GERMANY - FEBRUARY 03: German Chancellor Angela Merkel (CDU) speaks during a visit to the site of the new Wendelstein 7-X nuclear fusion experiment during an initial hydrogen plasma test at the Max-Planck-Institut fuer Plasmaphysik (Max Planck Institute of Plasma Physics, or IPP)on February 3, 2016 in Greifswald, Germany. The experimental device, which cost one billion USD (908 million EUR) and is comprised of 20 million components, was completed in October 2015 and was built to test the potential of a future reactor built using the technology of nuclear fusion, in a reactor known as a stellarator. The purpose of the institute is to research plasma physics to ultimately create a method of obtaining fusion power, the generation of energy by nuclear fusion as seen in the sun, to obtain clean, cheap and limitless energy, as opposed to that obtained by splitting atoms, the latter method employed by current nuclear power plants.
