    California's PG&E says to expect blackouts for the next decade

    This is what happens when you don't maintain your infrastructure.

    It's simply another refusal of socialism, leading to greed and indolence.
  3.  
    That's the power of labeling.

    Labelling ?

    Maybe a minor second cousin?

    Britain’s cheapest “virtual battery” could be created by hoisting and dropping 12,000-tonne weights – half the weight of the Statue of Liberty – down disused mine shafts, according to Imperial College London.

    Told ya!

    You don't want just to hang them passively and lower and raise them. The weights should be giant yo-yos and be spun up to high speed for the flywheel effect. That way the energy to hoist the yoyo is stored in the spin angular momentum. During idle times the yoyo could just "sleep", spinning at the bottom until the power is needed. Then the axle clutch engages and the angular momentum is tapped to raise the yoyo to the top of the shaft.
    So you don't need a big reel of cable at the top. The yoyo itself carries the cable up and down, adding to the KE-PE exchange.

    Hmmm. That's flawed logic you know.

    Hmmm...that's very good!

    It's a cost benefit analysis and intuitively I'll state that all the extra gubbins you need to support extra energy storage via angular momentum is better spent ($/KWh) on more weights eeyore depth.

    ETA And the cable weight consideration is in the noise.

    If you have a high water table, you could use giant pendulums and have the whole thing above ground. Pendula? Solar powered, self-starting, giant pendula. I have a prototype sitting on my workbench, perpendupetulizing away as I type.

    The sun shines, the pendulum starts to swing, the amplitude increases with each swing until you have a bunch of energy stored and you can extract it at will.

    Bonus points for making the pendulum bob a yo-yo.

    Inefficient compared with straight weights.
  10.  
    Is not.

    I meant the "Hmmmm..." was very good. Appropriate, don't you think?
