High induced votlages in open wires are a problem, but they're not the big one.

The biggie is common-mode currents in long high-voltage transmission lines adding a strong DC component to the current in the substation transformer windings - high enough that when the same-direction peak of the AC's cycle adds to it, the core saturates. Then the inductance of the transformer drops to the air-core value and no longer substantially impeeds the current.

The current skyrockets. The resistive heating of the windings (and the force on the wires from the magnetic fields) goes up with the SQUARE of the current. The windings quickly soften, distort, form shorted turns, melt, open, short out to the frame, etc. The transformer is destroyed, or committed to a self-destructive progressive failure, in just a handful of such cycles - too fast for the circuit breakers to save them (even if they DO manage to extinguish the arcs with the substantial DC component to the current.) Even if the transformer doesn't explode and throw molten metal, gigawatt sustained arcs, and burning oil (or burning-hot oil replacement) all over the substation area, it's still dead.

This happens to MANY of the giant transformers in the power grid. Each set of three transformers that has one or more failed members means a high-voltage transmission line that is shut down until the transformer is replaced.

There are essentially no spares - these are built to order. Building one takes weeks, and there are few "production lines" so little parallelism is available. What is destroyed overnight will take years to replace, while each intercity power transmission line is not functioning until the transformers at its end ARE replaced.

The current occurs because the transformers are organized in a "Y" arrangement, and the center of the Y is grounded at each end (to prevent OTHER problems). The transformers have enough extra current handling capacity to avoid saturation from the DC through that center connection to/from ground from ordinary electrical and solar storms - just not a giant one like we get every couple centuries.

The solution is to put a resistor in that ground connection, to limit the DC in the lines (and dissipate the energy it represents). Indeed, a few lines have such resistors already.

But a suitable resistor is a box about the size of one of the transformers. It's very expensive. And it only makes a substantial difference to the operation of the lines in such a once-in-centuries event. So most executives don't spend the money (and get dinged for costing the company millions) to put them in, to prevent a failure mode that hasn't happened in the generations since Tesla and Westinghouse invented the three-phase long-line power grid.

Or at least they don't until the regulators or their stockholders require it. Which means said decision-makers need a little educational push to decide it's worth the cost and get it done.

Thus articles like this. B-)

Of hosts, we could even call the file 'hosts'. Then, periodically, you pull a copy from the master to have locally. Simply set up a governing body to arbitrate name clashes (like 'mailserver') and you're good to go!

They can't do everything, which is going to lead them to doing a lot of things suckily.

How do they actually make money to keep those bazillions of servers running? Does anyone ever actually click on those ads?

It started when it became ok to simply "hate" GWB. You never needed a reason.

How are you going to create the atmosphere ON a human timescale?

That's the sound of you missing the point. TFS goes into great detail about facts of whats happened, then says "which makes the point" - but it never MAKES the point. It's just a groupthink argument that everyone must somehow naturally arrive at the same conclusion.

"Don't build anything, ever, and don't eat any animals, ever" ?

They can probably get really good deals on student versions of those products. AutoDesk, certainly, would like as many young people to grow up using their software as possible, so when they're out in industry as adults they can tell their boss to buy big-boy AutoCAD.

The F-35 is not an air superiority craft. I imagine the F-22s will clear the way, absolutely obliterating anything in front of them. There is nothing today that even approaches the air-to-air lethality of the F-22.

I live in Florida. Yesterday I had to call the Florida Department of Highway Safety and Motor Vehicles. All I had to do was wait for the option to press '1' for spanish to expire and I was connected immediately to a real person who answered my slightly complicated question easily, clearly and quickly.

I also own a business (and have owned two) in Florida, and every time I've had to deal with the Florida Department of Revenue (sometimes I got busy and forgot to pay my sales taxes) they have been friendly and helpful.

I wish, wish Cox Cable had the kind of friendly and expedient service Florida's government entities do.

Look for a hybrid apnea mask. Has nasal pillows and a lower portion that covers the mouth.

Too bad the solar wind will ionize and rip away any atmosphere that accumulates due to 1000s of comet impacts. Mars has no deflector shield like Earth has.

Did the study attempt to cope with the underreporting issue?

I'm wondering a little differently. I wonder how plugged in that gate representative must of been to find and successfully identify the source of the tweet and call the family off the plane before it left.

I say this because I don't see some SWA social media monitoring department demanding the tweet be removed in that fashion. I figure it was the 'dissed' gate rep herself that did it.

I'd have told SWA "Go ahead and call the cops. You'll hear from my lawyer."
