More consumption than a city
AN ARTICLE about the worldâs top 500 supercomputers on website informed reader George Neil: âThe Chinese National University of Defence Technology houses the 3.12 million core Tianhe-2 cluster, which has 1 petabyte of RAM, uses a proprietary interconnect dubbed the TH Express 2 and consumes 17.8 GWatt [gigawatts] of electricity.â It was still saying this at the time of writing.
âWow! Thatâs a computer!â George comments.
Readers puzzled by his reaction may like to know that, in round numbers, the total UK peak electricity demand is 60GW on behalf of a population of 60 million people â so London, with 8 million, could be expected to have a peak demand of 8GW, less than half of the stated consumption of the Tianhe-2 cluster.

Or, to put it another way, a European electric kettle uses a shade over 3kW, so 17.8 GW would be the equivalent of 6 million kettles. We do not have the figures for the equivalent in blue whales.
Georgina Seaman sends us a photo, taken on a road near Newbury in the English countryside, of a sign that says: âAccess to Wasingâs secret walled garden 350 yardsâ
Carrot dream comes true
THE spirit of âartisticâ product reviews is spreading more widely than websites offering gadgets like banana slicers and books about âhuge shipsâ (11 May). Clint Blight stumbled across a site where you can download the app for the companyâs mobile devices that run the Android operating system. When we looked there were 42,935 reviews of the app, giving an average rating of 4.3 stars out of 5.
Clintâs favourite, beyond those asserting the obvious benefits of the app in helping achieve world peace, is the one that states that it made a userâs dreams of becoming a carrot come true. And here we were at the curmudgeonly, unimaginative Feedback desk, thinking it was merely the most mundane of apps, allowing messages to pop up on a screen.
Make the parcel fit the sack
WITHIN days of our item about a one-dimensional parcel appearing online, six readers wrote to chastise us (8 June).
Tim Walker had been puzzled at specifying ââ â but the readers point out that it is traditional for postal services to specify an âindexâ of maximum volume in units of length. You take the longest dimension of the parcel and add to it double the width and the height. Mark Dowson suggests this is a measure of âthe difficulty of handling and packing the parcelâ and River Att has a plausible detailed explanation: it âoriginates with the need to fit the parcel into a standard sized postal sackâ.
We still find it a bit odd and pedantic. We are reminded of a very, very boring afternoon reading the old UK Post Office Guide and wondering why it was forbidden to send âquinine coloured pinkâ to India.
Beesâ âinfinite life forceâ
THE title of the sign William Pedder photographed at the Caledonian hotel in Edinburgh, UK, is âAbeille Royale Wrinkle Correcting Facialâ. The sign invites hotel guests to âInitiate your face to the high performance of this âexpertâ lifting and firming treatment that distils its infinite life force within the skin for a smoother and firmer face. ÂŁ150.â
Williamâs internet investigations revealed that Abeille Royale is royal jelly from bees, but he failed to find anything to explain the mysterious claims made for it on the sign.
Pickpocket training courses
SPURRED on by Feedbackâs reference to announcements by disembodied voices on Londonâs Underground (8 June), Jonathan Singer tells us of one he heard at the cityâs Victoria main-line station:
âCustomers,â the voice began (âwe were once called âpassengersâ,â Jonathan laments) âare warned that unofficial pickpockets are operating on the station.â
âDoes this mean thereâs a course they can take to legitimise the profession?â Jonathan wonders.
Wandering hyphens
CONGRATULATIONS to Ben Buckton for achieving a truly stupendous performance while training for the recent London Revolution cycle ride. His son Sam sends a screen-shot from a smartphone app that records Ben cycling 2.4 kilometres at 882.3 kilometres per hour. Feedback is wondering whether the app would work for buses. Sam is more concerned that the device will be âconsidered as illegal as performance-enhancing drugsâ.
Masterful design
OUR item about missing hyphens, featuring âAnti-skin ageing sun creamâ (15 June), reminded Peter Groome of a conference advertised on the UK Ministry of Justice intranet recently on the subject of âAnti-people traffickingâ.
FINALLY, Bob Seymour sends us a picture of a notice on a hydrofoil sailing between Sorrento and Capri. The notice details the âAssistant Procedures for persons of reduced mobilityâ travelling on the boat. It assures passengers that âthe persons with reduced mobility will be received by personnel designed by the masterâ.
âArenât we all?â Bob muses.       Â
