The "2nd burn" on this commercial fire pit made me think of rocket mass heaters.
They both have an initial burn, a heat riser of sorts, a secondary burn, temperatures well over 1000, and a very clean burn with much less smoke than their competitors.
This clearly shows that good ideas can be used more than one way.
It also shows that sound use of scientific principles can take more than one path and be arrived at by more than one person.
I know you believe you understand what you think I said, but, I'm not sure you realize that what you heard is not what I meant.
