Sugestion for External Link[edit]

To whoever is "managing" this page, may I suggest an external link to the "Heath Robinson Rube Goldberg (HRRG) Mixed Technology Computer" project at http://www.diycalculator.com/sp-hrrgcomp.shtml. The idea is to create a computer out of a mixture of implementation technologies, including relays, vacuum tubes, transistors, simple integrated circuits, pneumatic logic, magnetic logic, and so forth.

Interesting, but a far stretch from being related to the topic of this article. Femto 13:11, 22 February 2007 (UTC)

Pneumatique[edit]

I am astonished that Wikipedia has no article describing the history of the pneumatique, or pneumatic postal/ telegraph service in Europe. It was the "Express Mail" of its day. I can't write it because I don't know enough about the technical end without drawing heavily on this article:

http://www.compulink.co.uk/~mhayhurst/jdhayhurst/pneumatic/book1.html

and I don't want to make a Wikipedia article that just looks like I transcribed a website. --Bluejay Young 06:19, 31 August 2006 (UTC)

There's a brief mention at pneumatic tube. It could also be expanded with information from the German de:Rohrpost article which looks very detailed, if someone wants to translate. Femto 11:50, 31 August 2006 (UTC)

Cleanup Of Main Section[edit]

I had a go at cleaning up the head section.

I also put a bit more info to the Advantages of Pneumatics section using info from class notes.

Energy Density[edit]

The article claims that hydraulics have a "higher energy density". When I think energy density, I think stored energy. I can store energy via pneumatics by compressing the gas. Since hydraulic fluid doesn't compress (appreciably), there is no energy storage.

I'm going to change "higher energy density" to "Fluid doesn't absorb energy".

Also, I'm not quite sure what the previous author had in mind when he/she said "the slightest motion of the load releases the pressure". That doesn't make any sense to me.

Since fluid doesn't compress, moving the load away from the fluid a small distance depressurizes the liquid. The hydraulic system therefore doesn't keep pushing on the load like a pneumatic system would. 75.167.39.8 (talk) 20:34, 25 March 2008 (UTC)

Pianos[edit]

I was working in a piano rebuilding shop when several player pianos and reproducing pianos came in. Surely they represent the apotheosis of pneumatic engineering. 172.56.26.137 (talk) 20:13, 3 May 2014 (UTC)

No history section.[edit]

Just a vaguely-relevant picture of a type of locomotive from the 1920s.Landroo (talk) 11:53, 29 June 2014 (UTC)
