Fusion is one of the research fields presented by the interactive exhibition “Ideas 2020 – A Tour of Tomorrow’s World”. German Federal Minister of Education and Research, Prof. Dr. Johanna Wanka, opened the exhibition of the Helmholtz Association in March 2013 in Berlin. Now the show is touring the country, highlighting some of the major scientific research projects being carried out in Germany. Visitors encounter seven pillars; each representing a great challenge society faces today. Multi-touch screens provide fascinating insights into the work of scientists and allow visitors to ask questions about the future. One of those challenges – represented by an ice block – is the question how to organise a climate-friendly energy supply. It also showcases IPP’s research towards a future fusion power plant.
