One of my favorite food guys Kenji Lopez-Alt is a mad scientist - MIT-grad-turned-chef.
Recently he pointed out in one of his videos that if you take the ring top off your gas range and manually light it, you get this wicked concentrated flame shooting straight up
Probably not super safe, but it allows you to get your wok far hotter than possible with the tops on distributing the flame out, and that added heat will let you get those scorching hot wok flavors you normally only get in restaurants (which he specifically believes comes from vaporizing oils).
I may burn the house down but I think I have to try it anyways.
