Although you're being funny, morebeer.com does sell conical fermenters for fermenting beer that are temperature controlled using peltiers. They are capable of getting the beer 30-40 degrees below ambient. So, I guess the answer to your question is kinda "yes".
This might be useful for concentrating the heat in one place. However, what about using that heat by attaching micro-sized stirling engines to generate electricity which could recharge the batteries of a laptop? That would be kinda like a hybrid laptop: recapturing the wasted energy from the inefficiencies of the processor. That's something I'd like to see.
