Default massive yet tiny engine



Hopefully it wasn't patented. Because that construction is about 80
years old!
And when you look at the "cylinders" you know why it was given up.


They will have had to make some serious advances in cylinder ring sealing
technology for this to work. That many sets of rings traveling on the same
circular path without the benefit of oil (from below in a conventional
engine) will be a real challenge.
