it’s here! Instant coolness.. almost instant coolness (which is the est most of us can hope for)

V-Tex was developed as a low energy use, low cost rapid cooling technology that enables pre-packed beverages to be stored at ambient temperature and then, if required, rapidly chilled at the point of sale or consumption
The team found that by rotating the beverage at a certain speed to create a Rankine vortex the carbonated liquid could be mixed without disruption to the bubbles of carbon dioxide. The team also discovered that by simply rotating the beverage the vortex behaved like a solid, with the outer liquid cooling faster than the inner liquid. Tests showed that cooling rates could be improved by collapsing the vortex and then recreating it; this was achieved by a stop start rotational sequence. This pulsed rotation is the essence of the first patent filed by Enviro-Cool (UK) Limited.

Further tests revealed that it was possible to interrupt the vortex without stopping the rotation. This was achieved by rotating the beverage around twin axes. Cooling rates improved even further with this method, and a second patent was filed by Enviro-Cool (UK) Limited to cover this process.

the news sites are calling it ‘the reverse microwave’

Very interesting. Reminds me of the transitional phasing alluded to with the EZ water stuff

This is something my colleagues at CSIRO could have created, but didn’t. They are experts in using interrupted rotation to enhance convection and hence greatly speed up heat transfer rates. They’ve even got a patent on an enhanced mixing device using a similar process. The key is to set it up the external motion to produce flow that is chaotic rather than periodic.

PS, I know what a Rankine vortex is.

They didn’t apply themselves to it because they had their beer in the fridge,.

go straight to the payoff!!!
