treasure in a tube

I have spent some time researching pneumatic tubes now, and they always seem to be found in American and European places. But a recent ABC podcast from Canberra, has revealed where these tubes are hidden in Australia too.  In the walls and ceilings of Old Parliament!

Michael Evans, the manager of visitor experience at the Museum of Australian Democracy in Old Parliament House, spoke to Louise Maher on the radio recently, to talk about this treasure in the museum.

He describes how there were several sets of tubes, one to the Postoffice and another 3km line to the government printers for sending out the Hansards.

For those curious to see the tubes at the museum, you can see them in the downstairs gallery, at the old post office and in the Attendant's Booth in the House of Representative's Chamber. Not all the tubes are there, but there are "some ends of it you can see" (see photo). Michael exclaims, that it is "really an untapped project to go and map what is there and what isn't there".

There is one section that still works but is not in action at the moment in order to preserve the technology - however Michael says that they want to get this working so that their visitors can see and hear the tubes (the thunk!).

Listen to the Treasure Trove podcast here.

you can't fax a blood sample

Save space, save money, save time, and what's more, better patient care ... A new development at the University of Pittsburgh Medical Centre ticks off all of the reasons to install pneumatic tubes between their network of hospitals, and extend upon the existing lines. Pneumatic tubes are described this time, in the Pittsburgh Post-Gazette, as an "age-old technology that has disappeared from much of the business world", but one needed in hospitals because "you can't fax a blood sample". These Swisslog tubes extend far - almost two city blocks. The journalist describes the 3D plans for the installation as like a page from a Dr. Seuss book, interviewing a number of developers, including representatives at Swisslog and Pevco about the tubes. One states "as hospitals expand, they're rarely one building anymore", the new hospital one that requires a centralised lab connected easily to the different buildings. Space is about patient care, and the more you can hide away the better - pneumatic tubes are perfect for this, their metal pipes invisible to most who visit a hospital. It is not so invisible to many hospital designers and engineers however, who are designing the tubes in more and more hospitals, nor to the many lab staff whose positions now become redundant as the tubes do their work.

lost letter experiments

It seems that the lost letter has not lost its place in the world of research. Recently, anthropologists from UCL published an article in PlosOne where they used the lost letter technique to measure altruism. 300 hand addressed, stamped letters were dropped on London pavements, on rain-free days (hmm, not often then!). Their results showed that the wealthier the neighbourhood the more likely the letter would be returned. This is a finding which does of course have the potential to lead to negative stereotypes about kindness towards strangers, but can also be argued to point to some of the complex circumstances shaping everyday life in these neighbourhoods.

What does posting a lost letter show? The lost letter technique was first used in the 1960s by the social psychologist Stanley Milgram (of six-degrees-of-separation fame), as a perfect way to examine altruistic behaviour. His initial experiments involved leaving letters addressed to  favourable organisations and stigmatised organisations, finding that the former received more returned letters. The UCL experimenters were more controlled in the handwritten address, with the same gender neutral name on every letter, but it is interesting that the method itself is still used in research, despite the decline in posting letters.

the small world of pneumatics

As weird geographical chance would have it, I just happened to be two offices down from Christine, whose family owns a pneumatic tube system company in Germany.

The company is called HÖRTIG rohrpost, and is based in Bayreuth. They have been installing pneumatic tubes since the 1960s, into a variety of places such as hospitals, supermarkets, pharmacies and cinemas. Each system is tailor-made for its location, using innovative technologies. One of their latest developments is the CargoPlus model which has a diameter of 500mm and can take material up to 50kg. The company are also taking part in a project regarding the underground movement of cargo, while also expanding their horizons to China and other Asian countries.


The company showcases their work at various trade fairs, which Christine told me she remembered attending when she was younger, where they have elaborate displays, with tubing hanging from scaffolding. I hope to speak with other members of this family-run business in the future, find out more about how their systems are being tailored for hospitals and other buildings, in Europe and in Asia, and maybe even attend a trade fair to see this stall and learn more about this fascinating industry.

cfp edited book on steampunk

Brian Croxall and Rachel Bowser are seeking abstracts for inclusion in a proposal for an edited volume on steampunk. From their advertisement:

The anthology will present a varied look at steampunk culture and criticism, presenting a comprehensive look at the genre’s impact and development in the fields of art and material cultural. Accordingly, we seek proposals that explore any of a range of iterations of the genre. These may include, for example, analysis of:

• Steampunk fiction
• Steampunk film
• Steampunk visual art
• Steampunk fashion
• Steampunk performance
• Steampunk fan culture
• Steampunk in relationship to preceding science fiction and -punk genres
• Steampunk and feminism
• Steampunk and postcolonial paradigms
• Steampunk and Victorian studies
• Steampunk and technology studies

We hope to present this collection as of interest to both steampunk enthusiasts and non-specialists in the genre, as well as both academic and generalist readers. With this in mind, please submit proposals that are steeped in steampunk culture and criticism, that could be of interest to a generalist audience and that have a strong sense of the stakes of steampunk analysis for broader cultural studies.

Submit 500 word proposals to Brian Croxall (b [dot] croxall [at] gmail [dot] com) and Rachel Bowser (rachel [dot] bowser [at] gmail [dot] com) by 1 October 2012.

meet me in the st louis postal system

There is another nice essay about pneumatic tubes online, this time about the St Louis postal system, which you can find at the RiverFront Times blog.

Those interested in technological assessment may be interested the quoted list of advantages and disadvantages of running the system:

Advantages: 
1. High rate of speed between stations for limited quantities of mail. 2. Freedom from surface congestion. 

Limitation and disadvantages: 
1. Only five pounds of mail could by carried in each container; and all classes of mail could not be carried. 2. The minimum time between dispatches is 15 seconds allowing only 20 pounds of letter mail each minute. Therefore, vehicle service would be required to carry mail during heavy volume times. 3. The inability to carry special delivery parcels due to the size of the carriers. 4. The relays at station are built in delays but they are unavoidable requiring all stations to be manned and open during operation. 5. The inability to dispatch between intermediate stations during continuous transmission between any two points.6. Inability to dispatch to railroad companies without additional handling. 7. Complaints resulting from careless locking and accidental opening of container in transit causing damaged mail. 8. Dampness and oil damage to mail. 9. Service interruptions block an entire line. 10. Congestion from heavy mail volumes. 11. Equipment takes up rented building space. 12. Excessive costs.

medicine and literature

A new issue of Granta is out which may interest some readers of this blog. It not only has a beautiful cover - evoking, amongst many things, Carl Zimmer's science ink - but also a wonderful range of fiction, non-fiction, poetry and photoessays.

Depending on where you live, there are a festival of events to coincide with the issue, such as "A Spoonful of Fiction" at The Last Tuesday Society (admission price includes the Granta issue and a Hendrick's gin and tonic - see also other lectures in this series, including Sam Alberti's upcoming history of medical museum and the field trip to St Bart's pathology museum) and other events in London at the Wellcome Library, The Freud Museum, The Horse Hospital and the Hospital Club.

opening the tubes up to tourists

Pneumatic tube aficionados visiting Prague in the near future should be interested to know that the pneumatic post system there has recently been purchased by Zdenek Drazil from Windcom, who plans, according to the Prague Daily Monitor, to "revitalise it and use it in education as well as a tourist attraction at Prague Castle".

And it seems that those longing to send their mail by pneumatic post may have a chance to relive this experience if the venture goes ahead. Drazil says, "I would like the principles (of the pneumatic post) to be used in teaching the physical principles to students. I am also sure that the terminal at Prague Castle in the spaces of Ceska posta could be successful. Tourists could inspect it and send a postcard or a letter through it". Reason enough indeed for a visit!
