The hyper loop would reduce travel time from Mumbai to Pune to about 30 minutes from 3 hours; i.e., speeds of around 600 mph
The essence of this tech is: create a low pressure tunnel so that air friction is reduced and a special pod or coach then zooms within this tunnel; just like books / mails used to be chute through vacuumed pipes in a library.
don't think will travel through any window less tube like a book.
