There's undoubtedly a trade-off between rounder and longer. I was
thinking of a typical more or less rectangular backpack, which would
have a circumference much larger than a 12 inch circle. A typical
backpacking pack could accommodate a circumference of about 88 inches,
more than twice that of a 12 inch round loop. Granted, such a large pack
wouldn't exactly be inconspicuous on an urban hiking trail, but you
could always put some rocks in it, and pretend you're training for a
Grand Canyon hike.

Yes, it does not have to be round. The actual measurement of interest
is Circumference of whatever shape it is (e.g, the total length of the
radiator). A 12” loop or square, or whatever, is still going to have
a very low efficiency at this size point. But closer to rounder is
better …

The problem is loop diameter.
It doesn't have to be round.
