This method uses heat to pump liquid, and could therefore be used in pumps for coolants, for instance to cool microprocessors. Such a pump would need no additional power (it's run by the heat that needs to be removed anyway), it would have no moving parts, and it wouldn't require a thermostat. Whether this method will actually be powerful enough for applications in, say, a laptop, is not yet known. Pending funding, we will explore this in collaboration with Prof. Vinod Narayanan at Oregon State University.
