so this is more than just a concept...
Thank you for the example. It is good to know. From the URL, it seems
as if they did with that truck something that magnetic backup tapes did
before. Last time I checked, magnetic backup tapes still had higher
capacity than hard disk drives at a same dimension, but I dont know now.
In a similar vein, there is also a demo of IP-over-avian-carriers RFC
(pigeons). It is just half fun, and useful in some sense.
This aspect of using object things (trucks, planes, pigeons) to transmit
data, rather than electromagnetic waves, is also very relevant in a
satcom discussion. They talk about these ballons, cubesats, disksats,
sails, and more. They too might offer higher bandwidths but with huge
latencies. They might be useful for some application, too.
I think the original version was 'never underestimate the bandwidth of a station
wagon filled with tapes driving down the freeway' :-)
tape may have a higher density, but once you include the fact that tape is more
fragile when transported, and the time it takes to read/write the data on each
end, the value of RAID arrays of spinning rust compared to tape is very
attractive.
