"As an ex-silversmith, I'd love to be beating out a nice copper bottom for a car, but for the weight, aluminum gives even more heat transfer, and you can solder it easily with zinc based rod."

I totally believe you could easily solder aluminum. I'm not totally convinced it would be easy for me. In my (admittedly very limited) experience, conditions have to be imaculately perfect for that to work. I'd also be worried about long term galvanic problems if I stick copper tubing to aluminum plate, and/or I'm not crazy about aluminum tubing in an environment with a lot of vibration.
