Eight hundred cores of any type is TINY as far as supercomputers go. Most large US universities generally have at least one (if not several) supercomputers that are multiple times (if not an order of magnitude) larger than this. Never mind that most research projects on supercomputers NEVER use the whole system at once - it's more of a timeshare thing where you book however many threads for a certain length of time. Yes, the prospect of the research is interesting. That being said, other than that there isn't any impressive or really useful information in the article. What might be more intriguing is listing how long they plan on running the simulation and how many threads it's using.

There's already been lots of experiments with powering implants, but the issue (as with mobile electronics) is size. Efficiency drops severely when you make the coils small, and then you still need the powered coil very close to the device coil. The fact that targeted magnetic pulses can have an effect on brain function puts a damper on the options as well. I think that cellphones and laptops should be in the same category as 'waterproof equipment', though as far as exposed power couplings go, it isn't that difficult to have a smart plug that will not allow an electric short (e.g. from water) across the terminals to drain the battery. For example, a lot of electric razors have this.
