KedricThanks to comments from Josh Starnes, I learned that there is a better component that could replace the peltier modules which would help generate more electricity. I am going to try to obtain TEG thermo electric generators to apply in a future prototype. I am also going to paint the top heatsink aluminum plates black to help absorb more heat.

A project log for SEBS (Seebeck Effect Buoy System)
This Buoy, with peltier modules attached, will use the Seebeck Effect to generate electricity using the ocean and the sun.

It was Flat Black, I used a small spray gun and it had been thinned down quite a bit compared to what it should have been. You could actually still see the silverish colour of the aluminium.

Don't just paint them black. I spent about a month doing some test for a solar water heating system. We were trying to work out the best way to capture the heat from the sun using thin formed aluminium plates.
The best performance was with Aluminium that had the surface sanded (using an obital sander and from memory some 240 grit wet and dry) then coated with a thin layer of black. we had made a special solution for this. It was more of a mat black wash sprayed on to the surface.
Other interesting things we found was Annealed aluminium seemed to perform almost as well. We also tested Copper and the results of that were stunning. IIRC the treated aluminum performed just as well as the untreated copper.

Thank you, I will try your sanded surface method. Also, did you use metal spray paint or did you make a new solution all together for the thin layer of black?
