k I finally read the article. I think the article pretty much says what the usage will be:

The US scientists did the experiment to demonstrate how the random motion of water molecules in hot steam could be channelled into a directed force.
But the team, writing in Physical Review Letters, believes the effect may be useful in driving coolants through overheating computer microchips. ....................


.......The electrical currents now passing through microprocessors are so large the heat they generate can limit computing performance.
Many chips have cooling circuits nowadays, but these require pumps to drive the coolant, which in turn generate even more heat.
Suitably micro-patterned channels, argues Dr Linke, would make the coolant flow automatically. "It would be very neat if we could use the heat from the chip to be the pump, because you would not need any additional power, but also because the pumping only happens when the thing is warm; it would also be a thermostat at the same time. So it would all be in one package

Happy?
