This article reminds me of the pervasive university myth: Student requests 'a yard of ale' during an exam, as is apparently his right since time immemorial. Invigilator checks with authorities and eventually supplies said beverage... then when exam is over, student is fined for not wearing his sword! First heard at St Andrews but presumably told and retold around most ancient universities!

Erm, Margery (Thursday letters), to quote from the article you read "Desalination remains a 'very expensive, very power hungry' process" and "Water is 'heavy and incompressible, so if you start pumping it uphill, you pay lots of money', Green adds", That might be the reason?

Someone should tell Margery how much energy you need to get the water out of sea water. It's not cheap. We may be surrounded but without having lots of free electricity (from solar) it'll never happen. It also tastes foul.

Roger, Bookham, UK (Thursday letters), would you consider loaning it to the Titantic Centre in Belfast?
Lovely juxtaposition in Thursday's Magazine of the random stat (4,000 animal attacks on posties) and Dicken's quote ("Who did it? Dog was it you?")
