Obviously written by a true fan, trying to put a forgotten down under "Genius" in the spotlight, unfortunately the article leaves quite a few questions unanswered: 1.: Alright, I guess it's my mistake if I've never heard of a "spiral hairpin" before, and obviously there are pictures available via websearch, but if it's that important to the man's history a picture in the article would be nice. Also: the hairpin link should be fixed so it doesn't lead to a disambiguation page. 2.: What the hell is an "economiser"? What does it do? How does it work? Does it work?? 3.: What the hell is this "vaporizer" mentioned quite out of the blue in one of the last sentences? --BjKa (talk) 20:10, 8 November 2009 (UTC)[reply]
