I had the pleasure of meeting him during a a rare inside seminar of the Berliner Unterwelten, where he did a tour of the train track used by his one rail battery car gadget for one of the failed attempts and had a beer with him afterward. He told lots of stories from his exploits which were truly brilliant and funny among others, a remote operated submarine and fake tunnel systems. Also from prison and even some of the social hacking he did in the upper circles inbetween (he was super famous and gave interviews to tabloids at day while still spending time in prison at night). Turns out he‘s a really nice and humble true nerd with a bad childhood and background. He‘s a cartoonist now, but eschews the limelight these days and his brain is pretty damaged from paint fumes when he worked as a car painter.
