"The demonstration was performed with a minimum absolute pressure of 30 kPa and achieved a heat sink temperature of 85oC" 85c? Dosent sound like an option.

True the heatsink was hot in that test, but look at what's being used as a radiator.

The cooling coil is just attached (soldered/glued?) to a big flat plate. It is that plate that is getting to 85C. Imagine running that cooling coil inside one of our waterblocks.

I thought it looked interesting as a way to very effectively move the heat from the tiny surface of the CPU to a larger surface where other cooling can move it into the air more effectively.
 
Wouldn't the theoretical lowest temperature on die be above 0 degrees celcius for this, as it's water? They give figures for pressure, although I don't know what 30KPa is in millibar. I mean, you can "boil" water at room temperature in a vacuum, so maybe if it's a low pressure, the water wouldn't be able to freeze. Good to see all these developments though, it's always nice to play with some new technology :)
