While trying to research who Capt Warren was, I ran into this statement:
"Leonardo Da Vinci invented a double-walled briar pipe, cooled by the air that circulated in the air space."

Anyone know if this is true? They weren't using briar then (that I know of) but he invented so much neat stuff, maybe there's a basis? Was Leo a pipe smoker (kinda early)?
