As a corollary, I have done some unique stuff with charcoal. If I were 20 years younger, I'd turn the market on its ear. But, I really can't devote the time and energy it would take. I have a patent pending in an entirely different field which is taking a lot of money and time, but, if it is issued, will take care of more than retirement. It is not my first, but, it is, by far, the most expensive.
Lawyers value their time to an unbelievable degree.
It gripes me, chaps my ass, even, that manufacturers and purveyors of grills have no idea how to use them. Even the instructions are as stupid as the Japanese translations of computer manuals.
