The prototype has been thoroughly tested and the underlying principles proven. That's what the 2009 report is about.
"It's also pretty tiny. Even if it had wonderful thermal transfer, it's a tiny assed heatsink, and would be beaten by a "low tech" big assed heatsink every time" This is the...
The delay was not due to to any flaw in the technology. The cooler was hung up in DOE technology transfer red tape for much of the three years you're referring to. Licenses were finally granted to commercial partners in mid-2012. For manufactured products (i.e., physical things, not software)...
You can review the basic science and the prototype technology here:

The prototype was not on a chip because it was mounted to testing equipment. The prototype's purpose was not to demonstrate commercial applicability...
I wrote a magazine article about the Sandia Cooler and its inventor last year. Having seen the technology first-hand in prototype form, I can (I hope) disabuse some misconceptions about what I saw and the retail technology I hope comes to pass. First, while the prototype fan may have been...
