If you are worrying about that, you are doing things very wrong. The utility is presumably supplying no voltage; hence the need for the generator, and if it was, the last thing you want to do is to use your generator on the same circuit as the utility power.

Not sure which would be worse, being completely in phase (which would double the voltage), or completely out of phase, which would (try to) create about a 320 peak to peak voltage between the utility supply and the generator (or vice-versa), and cause some great fireworks. Remember that single phase AC power (what you have at your house) is just a basic sinusoid (ideally, anyways), with some theta that indicates its 'phase'. All the math you can do with sinusoids is true for representing AC sources; you just need to remember that you don't have loss-less paths, infinite current sources, and 100% efficient supplies.

Most rad hardened CPUs are RISC (powerPC, SPARC), there are very few options for x86 based rad hardened CPUs. Mil-spec wise Intel is doing well with their newer stuff (dual-core, etc.), but none of it has made it to the rad hardened world yet. The RAD750 is pretty much 'state of art', running at 166MHz.

Replacing an old 486 with one of these would require rewriting / compiling all the code running on them. Probably not enough of a performance gain in relation to the cost / risk of basically rewriting the code base from scratch.

This is the reason 100gpbs isn't being considered for lan use. It just isn't feasible at this point.

Stick a thousand machines on each end, and you'll understand why 100Gbps is needed.

Except that 90% of the world doesn't abbreviate Microsoft to MS... most people actually go and type whole words. Quicktype instant-message abbreviature typing is still (luckily) mostly restricted to instant messages and basement dwellers.
