A spokesman said, "Current development of Nodig Technology in particular will be shown on the test site (12 different stages will be set up for our visitors). At these stages practitioners can try out the machines themselves as well as sharing their experiences with each other.

"The evening will also be inspiring. Visitors will dive into an unusual ambience of the Sauerland-pyramids and can – if wanted – receive information about the geothermal energy heated park as well as taking part in an exhibition about the landings on the moon."
