In March 2014, Karlheinz gave a talk about futures studies and science fiction at the Andymon Club Berlin. Méô Mespotine, a well-known podcaster, and journalist, produced an audio file of the talk and an interview he had with Karlheinz. In total 2 1/2 hours for listening. It is available on the Phantastika-Site of Méô Mespotine.
Thank you, Méô!
