Water flows uphill

Clever use of water vapor mechanics

You make scratches on a surface in a certain way, and heat the surface, and water flows across the surface in one direction.  It’s a curious effect.  I’m not sure exactly what I find so appealing about this - maybe that it could have been done in ancient times if anybody had tried it?

BBC News: Scientists make water flow uphill (be sure to watch the video).

They’re thinking of it as a way to move coolant through computer chips, but I can also imagine it being used in sensor technologies, solar heat collection panels, novel chemical processes (like a kind of high-speed thermophoresis? )... Lots of possibilities come to mind.
