Muscle pump  Japanese firm Eamex has developed a pump that they
say could form the basis of anything from artificial hearts to
liquid cooling systems for laptop computers. It uses a plastic
that expands or contracts when a small amount of electricity is
passed through it, on the same principle as artificial muscles.
In a laptop, it achieves cooling performance that's 2X-3X better
than conventional pumps, creates no sound or vibration, and can
be made smaller and cheaper than anything around at the moment.
And as the manufacturer notes, the operating frequency of 1Hz is
close to the pulse of the human heart. Despite our status as
willing passengers on technology's heady voyage toward the
future, the idea of our laptop sitting there with its innards
pulsing creeps us out just a bit.  [Via Slashdot Japan]
