use powered electric coils to send small vacuum tube sized
mail containers with permanent magnets attached around
individual buildings and eventually around a city. Inspired
by see link [https://www.youtube.com/watch?
except powering the coils rather than the vehicle so you
have to lug the batteries around with the vehicles
(just use permanent magnets instead) and can just send a
canister of standard vacuum tube size. You could run the
coils around irrigation pvc pipe for an initial like prototype
model, because its got holes to prevent air cushions (rather
than going airtight, which was the main issue with vacuum
tube systems, maintaining a vacuum over long distances is
hard so it never scaled). The pvc would provide a smooth
surface for the cannister to move through and the coils
could be outside of that. You'd want to then protect the
coils thermally and electrically from melting the pvc and
from melting / conducting through anything outside. and
then your issues are, supplying power (easy, get it from
building or municipal power), switching (harder. I'd try and
do most of it through y-junctions and use electromagnets
to pull the 'packets' one way or another) and routing
packets (harder. I'd start with something inspired by how
packets are routed on the internet, so they can route
around blocked places).
Curb Side Blow Job

OP's misplaced and therefore unfortunately broken link, fixed
It's a YouTube video called "World's Simplest Electric Train", showing how to make a motor that is both homopolar and linear out of a battery, magnets, and a wire. [notexactly, Jan 15 2020]

||Aah! Some-one has stolen the paragraph breaks and most of
the punctuation! But welcome to the halfbakery.
||We've done and redone and re-re-redone variants on this
theme, so let me baptize you with your first bone. Welcome
to the Halfbakery and may your ideas all be more original
and/or researched than this one.
||and have capital letters.
||I would however be delighted at receiving (electronic) valves via a pneumatic tube.
||Nice category choice, though.
||yeah, ok, but not an inspired idea title like the one linked :)
||Well, indeed, welcome to the HB!
||Not much of a welcome - ie a bone for the first
idea. I'm cancelling that out with a +
||Kindness costs nothing (but cruelty is more fun) - however, this is just a smaller version of Herr Doktor Professor Musk's Hyperloop idea.
||Not to worry, have 4 paragraph breaks
||Welcome, [keira]! I fixed your link, which you should now see in clickable form below your
idea text. For future reference, you can add a proper link by clicking the [link] button down
there or in the left sidebar after submitting the idea. That will make it clickable with a title
and description, and also keep the link from being ruined by the halfbakery server putting a
space in the middle of it. (That's another thing to note: When you're writing or editing an
idea or an annotation, make sure you don't have any words joined by punctuation (like
hyphens or slashes) being broken by the soft wrap in the text area. Before you submit it,
just resize the text area so the joined words aren't broken across two lines, or manually add
a line break before the joined words. Otherwise, the server will put a space where the soft
wrap occurred. (I don't even know how it's possible for the server to know where the soft
wrap occurs, but apparently it does.))

||This implies that you intend this system to be used on scales larger than large cities, which
