This guy has the worst translated articles ever. It's even hard to understand what's the main idea of what they want to say. Ridiculously long sentences. Obviously he's not quite good at writing and directly translates word by word from his own language. When I see an article from this author I just skip it even though I love Tesla. Shame Notebookcheck don't care about it. Just ask a friend of yours to read any of Daniel's articles translated in English
