It's @nyrath 's fault I think about cooling fins.

@thisnorthernboy @nyrath you need fewer fins, fins rotated 90 degrees, or fins divided into at least three rings. The surface of each fin should be pointed directly out to space, otherwise the fins are heating each other.
@SkipHuffman @nyrath Dammit. Good point. There will be another ring of fins, so I'll adjust when I add those. Thanks.

I'll just mention that some historical radiator designs tried to cram in lots of radiators by interspersed-reflectors preventing radiator-cross-heating. See image. Feel free to totally ignore this comment.

For inspiration, you can go to the link and admire the pictures. Do not bother with the pesky equations.

@nyrath @thisnorthernboy @SkipHuffman I’m so glad I was able to make myself not mention this part of the physics šŸ˜†
