Microwave and fibre repeaters do the forwarding without waiting for the whole packet. They typically work bit-by-bit.

There may well be a little latency, but only a few bits at most, which at these speeds is inconsequential. There's no point in buffering when you're in the middle of a point-to-point link; that's only done when you may make routing decisions, but in a point-to-point link there's no decisions to be made.

Yes, stuff like that can happen. That's partly why they don't put wind turbines close to residential areas; also they are somewhat noisy in high winds at close range.

But if you mean, the tornado could carry the blades for miles, well yeah, but a tornado that big is going to fuck up so much other shit than the wind turbines that that's the least of your troubles.

> The other issue with wind power is that it can vary uncontrollably minute by minute. This is the kind of instability that needs to be leveled out by more storage.

You are wrong.

While wind power in any individual turbine can do that, the total power generated across a reasonably large grid, cannot. The power variations average out.

What happens is that the weather systems move across the grid, and this massively smooths out the changes at the short time scales (minutes). At the longer time scales, like hours-days - this doesn't help, but the kinds of instabilities you're referring to, these disappear.

The hours-days variations are usually proposed to be dealt with by using a mix of power sources,such as using solar and other renewables, particularly, if available, some hydroelectricity and (perhaps) batteries for any remaining.

Car key, house key, mailbox key, office key and my parents house key and a token for shopping karts. There is a USB key on it too, but I never think of it when I need a USB key... That's about it, it's already too heavy with all that crap.

I don't agree, aluminium is not easy to ignite at all in any kind of sustained way, unless you melt it and turn it into a spray, or you powder it (but then a lot of powders are pretty damn flammable), or you use high oxygen partial pressures.

Whereas, magnesium is not that hard to ignite, and it self sustains at normal atmospheric oxygen partial pressures.
