cars have been using the better radiator design for ... eerrmmm about 1000 years now...
a car designed and built in 1987...
it's just us bunch of geeks that thinks it's a new thing... that's all
oh and I think Leonardo Da vinci has the patent on the modern day Radiator, as well as the bicycle chain, and a whole stack of other things.... I would not be surprized to find a water-block in his stuff somewhere, either.... that guy is\was a time traveler, I'm sure of it....
