    Fascism would involve a government being an absolute authority, ruled by the decisions of a select few people without input from the public.

    No, not necessarily fascism, that would be simply despotism/oppressive - other political regimes exposed it as well without being fascist (see the "In Russia..." series). Not that the ideas/principles such regimes make use to justify the oppression would make difference to the life of the ruled.

    Accepting that a government has the authority to investigate threats is not fascism. It's the acceptance of the rule of law.

    I'd rather call it cowardliness. As every human creation, every law has limits - I haven't seen any law that can be applied as it is in all and every situation that the bitch called everyday life would come up with. Put the law above the sky, fail to exercise a proper control on the law (even if challenging it at times, if required) and one will get pretty soon into Pisso's justice.

    30 square kilometers of land for 5 megawatts output? To me that doesn't seem very viable...there's single wind turbines with more output than that.

    30000 sqm does not make 30 sq km. Let's try some computations of achieved efficiency:

    • Input - going maximal here. Solar energy flux - 1.44 kW/sqm (ignore absorption in atmosphere). Thus total input= 43.2 MW. Say it for 10 hours/day = 432 MWh
    • output - 5 MW for 24 hours=120 MWh

    Minimal modelled efficiency: 27%. - I'd say definitely a decent efficiency.

    Can they improve? Keeping into account the last step of energy transformation (thermal->electric) operates between say 825 K (molten salt) and 400 K (water at 120 C - moving the turbines) and assuming a perfect Carnot cycle, the maximum efficiency achievable would be lower than 52%.

    Aren't you confusing two distinct notions here? Like running the show and predicting how the show will evolve (aka modelling)?
    What's the difference between your suggestion and what just happened?

    Yes. The reservoir is currently full - because is has zero capacity. Damn'd cheap to build and maintain too.

    If you know the mean and maximum pump rates as well,

    Yeap. Mean/maximum pump rate: an infinite number of lakes per second (since the lake has zero capacity, I need no time to fill it in)

    then you can set a computer to fan the blades on the windmills,

    I just received the massage "Fan the blades, we can't take any more water in, nor can we transport the entire energy by our grid"

    I guess the above follows your predictions step by step. Isn't it wonderful how predictable everything is? How come this piece of news made it on /.? Everybody know that predictable is boring and boring qualifies for "slownewsday" or just plain "stupid".

    BTW, maybe I'm wrong, but I think that the grid has been modelled before building/laying it, to plan/design it for a certain energy transport capacity. Too bad the unpredictability of the storm passed over the assumption set injected as input in the initial modelling/design.

  13. Re:Store in a water tower on In Oregon, Wind Power Surges Disrupting Grid · · Score: 4, Interesting

    Pumping water with wind energy insures you can use wind energy as a baseline power supply (although it's actually hydro energy that achieves it). You lose some efficiency in raw power output,

    I didn't say that balancing the input/output and buffering is a bad idea.
    I only said that if the energy is needed in the grid, you should deliver it directly instead of storing it in water towers.

    Maybe I took wrong your first post when you say taking this idea a step further for local power generation: Why convert to electricity in the first place?: it looked to me as you suggested to always store it as hydro - if that's indeed what you were saying, my argument was against "always" which should be replaced with "when in excess".

    Mitigating that problem by reducing efficiency is a trade-off that can really help renewable energy become more mainstream and reduce our dependence on fossil fuel

    So, reducing the efficiency plus investing in a hydro buffer does make the energy become mainstream? Something is wrong in my world which, like/agree with it or not, is currently driven by prices. Until the freaking "price on carbon" is not injected into the world's economy (in no matter how: "trade-able emission quota", "penalties for extra emission", etc) I don't think this is going to happen.

    Other than that, even buffering an unpredictable input it is not without technical difficulties:
    a. in your example, to store the excess in Norway lakes, you need a cable that's currently the wonder of submersible cables. And TFA was saying "the grid is the bottleneck, otherwise the CA people would be happy to suck the energy in". If you need to lay a line to the appropriate lake and build a hydro on it, wouldn't it be cheaper to just enhance the current grid which acts as a bottleneck?
    b. what if you don't have enough water around to raise in the tower/lake? The "buffering" solution will still be valid, except that hydro is not the only buffer possible
    c. what if the lake you use doesn't have enough capacity for the excess you record? What makes more economic sense: invest in a "bigger lake" or just let the excess go?

  14. Re:Stop putting it on the grid! on In Oregon, Wind Power Surges Disrupting Grid · · Score: 1

    I thought due to the sporadic nature of renewables that few of them are plugged directly into the power grid and instead the energy is used to, for example, pump water from a lower storage tank/lake into a higher one? That way they know exactly how much power will be generated by the release of the water and it is entirely predictable.

    One thing that you won't be able to predict is when the tank/lake will be so full you can't pump in it any more.
    I guess I'm trying to say that: what is unpredictable will stay unpredictable (no matter how many buffers you use to cushion against values you cannot handle).

    Dutch wind energy is currently being stored in Norwegian lakes (because here it's flat, and they have mountain lakes). Apparently the advantage was worth laying the worlds longest underwater power line between nations.

    With my emphasis on the quote above, I reckon that if the Oregon->California electrical lines would be of the same quality, then we wouldn't see TFA on /., would we?

    But taking this idea a step further for local power generation: Why convert to electricity in the first place? If you pump water to a higher place [etc.]

    Now, as a Dutch you should now that the Dutch windmills were used initially to pump water out, not to generate the electricity.
    Where is this relevant? If your main purpose is to generate electricity, then each step of transforming energy in different forms will cost you at the bottom line (efficiency goes down). I'm not saying that transforming wind (kinetic) energy in water accumulation (potential energy) is stupid if you have excess of wind energy But if you don't have excess, then direct transformation into electric energy will offer you the best return.

    This is where the analogy with the TatsLotto serves. Either way: play always you favourite numbers (keep thye beam in the same position) or change them from one game to the other (sweep the sky), the probability to win is the same if you play a single ticket (using a narrow beam).
    Granted, if you know a region where is more probable to find what you are looking for, the analogy with Lotto stops. But also exploring only in a certain region will make you prone to miss other debris that may knock down a satellite of your customers.
