    Not an option for many renters.

    And at least in the US our economy is still pretty split and divided, with a surprisingly large segment being poor. Here it makes much more financial sense to skip the home theater all together and use the cinema a couple times a year instead.

    Yes.

    Cinemas can give you all that without the space requirement of a large TV.

    You need to find a better pharmacy. Mine is very good about dealing with generics and getting any prescription that can be filled by a generic changed so it can. It doesn't come up often because my primary care doc is also generic-friendly.

    Just for comparison, where I live in Australia, if the doctor has put down the name of a brand rather than a compound or mix of compounds, pharmacists are legally required to ask you if you are okay with a generic if one is available.

    I was about to say, this is a perfectly feasible solution. Pick a partisan outlet (Fox News is one possibility, MSNBC is another), get all your information from there, and you will never have to think again.

    Another option is to read any Internet comment section (even Slashdot works for this). This will want you to go away and hide from all humans for a long time; no information overload there.

    Pumped hydro works at a hydro plant for the simple reason that the infrastructure is probably already there and the geography is probably already suitable.

  14. Re:We should have batteries at every substation. on Tesla Big Battery Outsmarts Lumbering Coal Units After Loy Yang Trips (reneweconomy.com.au) · · Score: 1

    No it wouldn't. The problem is rarely that power can't get to a substation from a generator; if that happens, say because of severe weather, you have bigger problems and batteries will only last so long. The problem is usually that the network as a whole can't cope with demand and the operator needs to quickly turn on some stored energy for a short period of time while a big plant is brought online.

    So a better solution would be to put a storage system at every generator. Battery is only one possibility; pumped hydro may be more appropriate if it's already a hydro plant.

  16. Re:AC frequency on Tesla Big Battery Outsmarts Lumbering Coal Units After Loy Yang Trips (reneweconomy.com.au) · · Score: 4, Informative

    I've worked a little bit with data from the AEMO. I'm not a power distribution engineer, but I did to learn enough to be able to explain it badly. So here goes...

    One way to think of it is that all of the equipment on a given segment of the network synchronises to the frequency of the network, but tries to nudge it ever so slightly closer to 50Hz. If every piece of equipment on the network does this, the network as a whole trends towards the correct frequency. The system can tolerate some drift, so each piece of equipment acting independently can force the network as a whole to keep to 50Hz as long as it isn't overloaded.

    A typical alternator that you may find in a generation plant is designed so that it will produce 50Hz when fully loaded, that is, whenever the amount of power that it's designed to generate is being drawn. When none of the power is being drawn, it physically turns around 4-5% faster, so it might run at 52 Hz if you did nothing. So if the full power output of the generator is not being used, you need to physically slow it down.

    That's easy, but of course the specific technique depends on how the alternator is being physically turned. If you can turn down the amount of fuel (trivial for hydro, almost as easy for a gas turbine), you do that, or you might use a mechanical or electromechanical governor on a coal plant.

    The problem happens when the network is overloaded. When you draw more power from an alternator than it is rated to produce, this acts like an electromechanical brake, and it will run slower than 50Hz. You can't force an overloaded alternator to run faster, so any attempt to increase the frequency won't work. The only fix is to not overload it by adding more power to the system or reducing demand.

    One of the key reasons why the South Australian government wanted to build the Tesla battery was because the AEMO couldn't get a generator turned on in time and so had to shed load by deliberately causing blackouts in South Australia. The amusing thing about TFA is that we may have just discovered that the Tesla big battery may be designed to protect the SA grid from the AEMO.

    Just for completeness, I'm using the word "network" here to refer to a region for which the frequency is synchronised. I believe this is true for most of the NEM; TFA seems to indicate that Hornsdale (SA) and Gladstone (QLD) are synchronised. However, I seem to recall from the data that Tasmania's connection is via a HVDC link which can work in either direction, so presumably Tasmania's frequency doesn't need to be synchronised to that of the mainland.

    The AEMO, by the way, is essentially a big integer linear program plus some human intervention in the case of emergencies. The ILP represents the network constraints (e.g. the capability of every generator, the maximum current of every distribution line, a squillion contract clauses) and tries to minimise dollars per kWh.
