It would be interesting to see how that would work if you made bigger versions. It was a lot smaller than the others, and I'm curious if it would have to be as big as them to match them or if it would match them somewhere between its current size and their size. Also, I wonder how much details matter? That certainly looks quite a bit different from the Sandia unit. Sandia was claiming a large increase in efficiency over other units, and usually you only get that kind of increase with either a fundamental breakthrough or by using known methods but getting it all tweaked and tuned just right. I think Sandia's is the second kind.

The conclusion of the video is that it does work, but the performance is not as good as the larger, traditional designs.

  The performance is below low profile traditional coolers like the noctua too, it doesn’t work as in live up to it’s promise.

    The Noctua was 37mm, the Sandia was 27mm. I don't have performance per unit volume stats, but I suspect the Sandia would perform well there. Performance per dollar, though... maybe not.

It looks like that design has diverged significantly from the Sandia one, probably because they couldn't manage the tolerances the Sandia design needs. Given that it's a first attempt to bring the concept to market, and that it appears to be significantly compromised, I don't think "it doesn't work" is a fair characterization of the actual Sandia design. It might well be completely impractical for the commercial CPU cooler market, but it also might be the case that a bit more R&D and tooling up could get us a really effective new cooler design. Improvements could include [perceived] noise reduction as well as better efficacy.
