MSI Develops a Heat-Driven Cooler

Posted by Soulskill on from the it's-not-easy-being-green dept.

V!NCENT tips us to a write-up about an addition to MSI's Ecolution motherboard which harvests heat from the chipset to power a fan. The device is based on a Stirling engine. The heat from the chipset expands a trapped gas, which pushes against a piston to generate power. The article contains a YouTube video of how the device works. According to MSI, the device has 70% efficiency.

    That being said I'd be surprised if they were as high as 70%
    Prepare to keep those eyebrows exactly where they are- The 70% refers to the transfer of heat energy to air pressure 'power' within the piston. It's still impressive, but the +70% claim relates only to one step of the process.
