He is talking about tubes like this: https://en.wikipedia.org/wiki/Pneumatic_tube
Interested in Language
Hello, everybody who's browsing this topic!
(The conversation is about a new high speed train Hyperloop).
- Is this around the evacuated tubes? The vacuum tubes. Like the old bank...
Why did he say the old bank here? Is he reffereing to a shore of the ocean/sea etc? What does a shore have to do with a vacuum tube?
Could you give me a hand with this, please?
A vacuum tube is AmE for a mostly-obsolete electronic component. The same thing is called a valve in BrE. I don't think Elon Musk would describe his evacuated pneumatic tubes as vacuum tubes because the term would be ambiguous and archaic-sounding.
I am not a teacher.
Yes, I see your point, but I just can't understand what's the deal with "the old bank".
The article bhai provided a link to tells us that pneumatic tube systems were commonly used in banks.
Thank you for the clarification!
