So, if these can be networked together to perform massive calculations related to gravity, something tells me that they can do the same for modeling nuclear weapons detonations. Is the PS3 banned from export to Iran or North Korea???
I believe (though I am nowhere near certain), that the PS3 is manufactured in Japan. Our exports controls have no jurisdiction over it.
Somehow I don’t think the question is if they’re banned from export to those countries, but rather if the countries in question allow them to be imported... could you imagine a ‘good’ Muslim’s reaction to female video game characters?
Honestly, I wouldn’t really worry - if whoever wanted to simulate a nuclear explosion, sure they could wire a bunch of PS3’s together, but they could just buy computer parts off the internet and assemble them by hand, or wire a bunch of ‘normal’ computers together, the only real difference being the cost, and something tells me that if you have the money to build nuclear weapons, you have the money not to need to be cheap about how you get your computing power.
