From Chris Collins
Your article about vat-grown meat (5 July, p 18) prompted a thought: “How about a milk machine?” Put grass and water in at one end and get milk – guaranteed free of tuberculosis – out of the other.
The problems of making an acceptable product would appear, to an ignoramus like me, to be far less than those of animal-free meat production.
