After all, there are now examples of crematorium furnaces linked to swimming pool heating systems so as not to lose the heat....a bus pass in to the centre and we have even better vertical integration, or is that horizontal in this case....
Reminds me of the Private Eye cover with the burning of Princess Margaret in her "stake" - a photo of Slough Crematorium and the chimney saying "One last smoke" - the building with a bubble "It's what she would have wanted."
