Thomas Edison invented the gas pressure regulator that we still use, initially for this specific gas. To think that carbonated beverages, medical gas and welding all come from this is kind of cool, even more so due to the design being mostly unchanged to this day. He used to 'study break' with laughing gas. I think that might be the most interesting of his inventions and it may be one of the few still in use in the same form.
