Hi there, Rob That thread led to an extensive discussion into the depths of "vacuum storage". It would appear that storing compressed air is no problem but 'the whole concept of "storing vacuum" is a little disturbing.' Well, you can certainly pump (...)

(...) Now things get a little philosophical :) The air tank itself has no idea about vacuum or pressure. The only thing the tank stores is a pressure difference. The difference between the outer pressure and the inner presure. This difference might (...) (23 years ago, 2-Mar-02, to lugnet.technic, lugnet.robotics)

(...) You cold use the "stylish" hard plastic tubing that came with a lot of Technic sets in late '90ies and also act's as outer hose for flexi cables. Of course you'll still need small portions of pneumatic hoses but at least the amount is limited. (...) (23 years ago, 2-Mar-02, to lugnet.technic)

(...) Exactly! (...) That's right! (...) Oh oh!

As was carefully explained in my earlier post at (URL) is, you can store compressed air in a blue air tank (or as many of them as you have in your possession) and then release it for use later on. Then you charge it up again. (...) (23 years ago, 5-Mar-02, to lugnet.technic, lugnet.robotics)
