During my college days many years ago, I pondered redesigning my MGB's
heating system. During a chemical engineering course on heat transfer, I
started thinking of a design using a higher rpm blower and possibly altering
the impeller diameter to pump more air over the little heat radiator.
But I never got to putting my thoughts into action, and thus fame and
fortune was once again narrowly averted.
