Nanotech Yields Major Advance in Heat Transfer, Cooling Technologies

In these experiments, water was used, but other liquids with different or even better cooling characteristics could be used as well, the researchers said. The coating of zinc oxide on aluminum and copper substrates is inexpensive and could affordably be applied to large areas.

Because of that, this technology has the potential not only to address cooling problems in advanced electronics, the scientists said, but also could be used in more conventional heating, cooling and air conditioning applications. It could eventually find its way into everything from a short-pulse laser to a home air conditioner or more efficient heat pump systems. Military electronic applications that use large amounts of power are also likely, researchers said.

My first post so please excuse any infelicities.

This is a boiling enhancer; it will be effective if that's the phase change you want. Other heat exchanges are also working on nanoscale experiments; see http://www.faqs.org/patents/app/20080245512

the guys from Reaction Engines Ltd (the ones from the Skylon project) claim to have created the best heat transfer ever, which is to be used on their SABRE Engine, which is the thing that would make Skylon possible. Of course... their system is ultra-secret.

Thanks everyone. For Polywell, I'm mostly interested in non-boiling water heat exchange to protect the superconducting loops. I'm hoping we will not need to use boiling water for power production, but hoping doesn't get us much...
