Whoever did that, is my new hero.

gives me a reason to drink more beer

Extra point for the built in insulation/silpad!

Finally! A good use for PBR!  ;D

Ha, cool.  8) I've used aluminium from an old oven, but this one has style, too.

Sir, that heatsink is the copyright of the Coke-Cola corporation  ;D

Very imaginative.

Any more soft drinks jokes to come?

Beer bottle caps are generally steel so not as good thermally as aluminum but +1 for recycling.

R U saing an EE sir shall have the beer canned and not bottled?

> not as good thermally as aluminum

When the metal-to-air resistance exceeds the resistance in the metal, the metal is a secondary factor. Many steel heatsinks work fine. In part because steel is cheaper than aluminum.

Yes (right as usual), for that application the thermal resistance of the steel cap is not significant.

I don't think I've ever seen an aluminum bottle cap, while maybe an aluminum beer can could find some use in DIY heat sinks. Problem there is that the aluminum cans are so thin they might have trouble with heat spreading.

Who hasn't made DIY heatsinks?

I've gotta say, google image searching "DIY Heatsinks" wasn't nearly as interesting as I expected...  ;D

The result of the demise of Radio Shack.

I haven't but only because I hadn't thought of it. I've done my share of equivalent hacks.

We definitely need a pic of the other side, so we can judge the maker by what beverage he (she?) drinks.
