"As I understand it, this technology is more suited to providing lesser coolants with thermal characteristics closer to that of water without many of water's inherant problems, corrosion for example."

I believe this refers to the thermal conductivity of straight water with nanoparticles. It references paticals of both Al and Cu.

"For example, the use of A12O3particles ≈13nm in diameter at 4.3% volume fraction increased the thermal conductivity of water under stationary conditions by 30% [6].Use of somewhat larger particles (≈40 nm in diameter) only led to an increase of less than ≈10% at the same particle volume fraction [5]; more in accord with theoretical predictions[7]. An even greater enhancement was recently reported for Cu nanofluids, where just a 0.3% volume fraction of 10 nm Cu nanopar-ticles led to an increase of up to 40% in thermal conductivity [8], a result that is more than an order of magnitude above the increase predicted by macroscopic theory. Currently, the origin of such remarkable increases in the thermal conductivity of nanofluids eludes theoretical understanding."

It doesnt mention water in motion
