  1. Seriously 47? I call bullshit, there have to be more Russian trolls on twitter at any given second. And Americans, and Germans, and Australians, and Indians. Trolling is a world wide passtime.

    No. The battery wasn't close to big enough.

    Where spinning reserve is required is determined by the physical layout of the grid. Transmission areas (parts of the grid well enough interconnected that they can be treated like one spot when looking at the overall system) 'must' maintain reserves, but the spin can be a line with available capacity and generators in the next area. Truth is that all areas are in spinning reserve violation at least a few hours/year.

    It gets really complicated, really fast. You can have one plant supplying power to distant load and acting as reserve for local load. The distant load will have to have plants on standby to account for the non-firm power contract. Which can still save everybody involved money (the standby plants are inefficient, but cheap/obsolete).

  3. My point is, nobody is going to launch anything until...never. It's just cheaper and easier on earth.

  4. What were the specs for expected input power you got? Switchers don't care, but you started the design process with a power spec, the same spec every other power supply was designed against.

  5. Electric motors. If switching power supplies ever become a majority of load, the grid will have a reactance problem

  6. To really fuck things up, shutdown one phase while you leave the other 2 running. That's how you get bent generator shafts.

  7. No atmosphere. That's about 50% right there. But...

    Launch cost has to be less than the cost of just building more on earth. Which means it will have to wait until we have orbital tethers or can make the photovoltaics on orbit from material we find in space.

    LEO spends almost half its time in earth's shadow.

    The grid worked as designed. News at 11.

    Steam plants don't come online in 6 seconds, they just don't.

    First the UPSs, then load curtailment, hydro and combustion turbines, finally the steam plants and steam parts of combined cycle plants.

    The real point (beyond the usual /. 'Ol Musky' blowing) is that apparently Australia was in spinning reserve violation when this happened. Your supposed to have enough power spinning to cover you single biggest unit/transmission line falling over (as they say in Australia).

    They are both affected. But power companies will let the voltage drop while holding frequency as close to theoretical as they can. They even run 0.1 Hz high or low at the end of the day to get the correct number of cycles for the period.

    If you've ever designed a power supply, you'd see that you must accept low/high voltages, but should expect the frequency to be fairly steady.

    Like I say, the Ds have lost control of their lunatic fringe. Which is what makes this post plausible.

    As the lunatic Ds run out of energy, Rs will fill the gap. Just as Ds pretend to be clansmen to push their agenda, Rs pretend to be neoStalinists/Antifa. Which doesn't mean that real clansmen and commies don't exist, just that they aren't THAT stupid...granting some are, like you say Waters.

    These people are obviously just fakes, making Democrats look unhinged.

    But it's believable because the Ds _have_ lost control of their loonies. Unless the Ds check their lunatic fringe, Trump is good for two terms.

    At this point NN supporters have lost their feeble fucking minds. A law that was never implemented is _needed_ and a necessary practice should be banned because 'rights'.
