The return of pneumatic tubes
(www.technologyreview.com)
This is a most excellent place for technology news and articles.
I want one to get beer from the fridge to the couch. I could move the fridge next to the couch, but if a pneumatic system is an option, I assume I don't have to explain which would be the better choice by a land slide. Cool beers on the couch, in the garden, in the bath tub, etc. I could fire my wife.
Of course I'm joking, I would never exchange my wife for a pneumatic tube system. I don't have a wife.
