If they were really stupid or just unsafe and working with a live transformer, it could have shorted out with a dropped tool or something. Might have had an arc flash over in the transformer which could have vaporized the oil. I don't work on transformers, but I do work on electric motors, which are transformers with rotating secondary's.
Of course, if none of that is true, then i have no idea.
2 weeks? Wow! I wish I lived in your country. Here in Ohio, US, I had to work 2 years to get 2 weeks. my third week comes in 10 years. Course my company probably underpays everyone but the division manager.
After glancing at the article, this idea came to mind: For field use, a sort of Vertical Typewriter in three pieces. The "writer" itself would be a vertical tube with little pushers filled with an amount of powder. Attaching to this tube at the bottom would be the message holder, where the bits of powder would rest. The third piece would be a tamper to tighten the whole thing up so it doesn't spill out. The message holders would have to be strong enough to hold the compressed power, but be "inconsequential" enough to burn with little to no light output of interest, or just have the reader calibrated to subtract what it itself puts out. Powder amount Vs letter frequencies and numbers aside, it seems like it would work.
Something perhaps the federal government needs. A pool of IT professionals that are available to all federal agencies, with the full range of clearances to keep critical, and not so critical, networked government information and hardware safe from ill-intentioned eyes.
Furthermore: "One U.S. hospital was recently hit with a denial-of-service attack that knocked its critical services offline temporarily. "There have been several close calls" including that one, notes Perimeter eSecurity's Prince, who couldn't reveal details about the attack on the hospital. Prince says the hospital was able to deploy some redundant power sources to keep its operations going during the attack on its network."
Many of your newer "and not so new" engineering controls are network-able and web enabled. All of your mechanical engineering's PLS's, HMI's, various sensors, are all pulled into one panel for convenience and productivity. Someone gets into the network, finds the address of the industrial power switching controls and faults it out, at the same time faults out the PLC's controlling the generators. Now the maintenance staff is power cycling control hardware as fast as they can because the hospital no longer has power.
Perhaps a useful diplomatic solution would be to offer coal stack scrubbers (?) and various mass pollution control technologies at reduced or less cost in exchange for the US easing up on whatever we could ease up on.
I'm not trolling, I'm advertising! Besides, this discussion might have the kind of people reading it that my friends company is looking for. However, being score 0, I doubt many will see it.
Speaking of that, some friends of mine are developing a low cost Point of Sale system, built on an open source operating system. Among many features, it will be a cash register, time clock, inventory management, take credit cards, etc. They already have all the hardware they need, and is in use in several locations. If anyone was interested, I could point interested parties toward them. (Full Disclosure: I'm an investor)
For those that make their own setups, do any of you use 3 Phase AC Servos? Add a propeller to the shaft and you've already got a generator. One could also use DC Servos, but then you'd have to replace brushes and hope the commutator bars don't wear out (good luck with that). With the AC servos, the only thing you really have to worry about wearing out is the bearings, and those are cheap.
Unless you want all three phases, I imagine one could hook up 3 identical transformers to the power pins in a Y setup for balance, then either series or parallel the secondaries to have the motor output as AC 1 phase. OR, yank apart a frequency drive and run the power leads to the diode block, and the output to the bus capacitors, and have some really smooth DC.
Most servos I've worked on are IP65 totally enclosed non-ventilated, so no worries about anything getting in the motor, water or critters.
As for getting a servo, try to get one without a feedback option;IE an encoder, because unless you want to know how fast the servo is spinning/which direction/how many times, you won't need one. Try looking on ebay for ones with bad feedbacks, and hope they don't have problems with the windings.

Vaporizing until Yuma = Arizona Bay...

Someone either sounds nervous, or a poor loser.

one of my friends had something like this, his had DOS to XP or something, was on a DVD though. He lost it or something.
