First, I have to say: "goddammit Adam and Jamie, HOW MANY FUCKING TIMES DO YOU HAVE TO BUST THIS MYTH?????"
good point they did it whit old type mirrors, new mirrors who came up whit a new argument that it could work. The concept sonuds good on paper though it fails in practice the best they got it to do was singe the wood and the boat would only haveto move a few inches and it would be good for a few hours before one could set up the mirrors aggain.
