Who heats the sand to 1700C in your house? -Read the bloody post. I specially put a bit in it to make sure you would not get confused and you still did. OK. Who heats the sand at all? Anyway, your topic was electricity storage. You can't. |

You brain has gone wobbly again. Let us know when you sober up enough to track the flow of debate. Lets take a step back and work on this accounting business to work out how affordable it is.
I was doing it on a per household basis, a bit like you often cost a manufacturing scheme on the basis of the product price. It's just an easier format to work with.

And you continue to be so bloody rude. And you still haven't grasp that electricity is rate. It's kW, not kWh. |

And you continue to be so bloody rude. And you still haven't grasp that electricity is rate. It's kW, not kWh. I'm talking about energy, not power. The system needs to store enough energy and return it to the grid at a power that supplies demand. The problem with your potential energy storage solutions is for a given mass, it does not acquire a lot of energy vs height, so we try an alternative where we store it as vibrational states in the lattice of the material. Molecules have several degrees of freedom and each one is a store of energy, e.g. they have two rotational degrees, three translational degrees and where you get say like a pair of atoms you also get one where they oscillate closer and further apart from one another as if they were connected via spring. All this happens where you energy stays in the same place, which is convenient. So what is not to like? Lets try and have a reply for once that does not include 'you' in it. I'm sick of hearing about myself. This is about energy storage. |

I would build a system that would be say a million tons of sand which is electrically heated and has a heat exchanger that carries the energy to the heat engine. I understand in power stations they have a multi-phase turbine system that efficiently removes as much energy from the heat as possible where your loss in the first stage is used by the second, and so on, all stages tuned to work optimally under a steady state. |

In addition, push any cooling water / fluid through the pile until the temperature rises to a point where the it is no longer useful as cooling.

Take your pile of sand and bury electric coils throughout it. Run current through the coils. (obviously this is just a sketch)
When demand exceeds supply, use the hot sand to generate electricity

Organic materials have a complicated chemistry. |

Yeh, I was aware that "biofuel" is an trendy thing these days to the scientifically illiterate. We ban smoking, but there isn't a lot of difference between burning wood and tobacco. Tobacco for sale reckons it has millions of harmful chemicals. The proles know that, but fail on the corollary. |
