Automated water heater control for optimizing hot water cost

As the price of electricity can vary by a few hundred percent within a 24 hour period, and the water heater is basically a large insulated kettle, it makes some sense to only run it when the price is at its lowest. Right? Makes you think though, this thing, electricity, our way of living is completely reliant on having this available absolutely all the time with very little margin for error. 0.2 Hz is the acceptable normal deviation, 0.5 Hz deviation is a systems failure. Very few businesses, services etc have fall back procedures not reliant on electricity to still be able to operate at all. Even if it could be done with pen, paper and cash, it's very difficult, if not impossible to do so and still be compliant with all regulations and requirements set forth by the tax and book keeping laws. When the power goes out, what's more important, that people can still buy food with legitimate paper currency, or that the ant f--kery is followed to every last letter? We'd rather have people go hungry and sick for not being able to trace very single cent in every single transaction. With price fluctuations like what we're seeing now, what does that say about the supply and demand for this essential service, and the health of the system as a whole? Imagine any other commodity, the price of fuel e.g, being 10's of cents per litre one hour, and a euro or two 12 hours later. Difference being of course that fuel can be stored, electricity can not on a system wide scale. Forget about batteries being used for that, it's just sillyness. It is a really silly idea to replace reliable predictable electricity production with weather dependent, unreliable, polluting wind mills and made from/with toxic materials solar panels.. Don't get me wrong, for something small scale, an island operation, not tied to a grid, solar panels, a little wind mill and some 10s of kWhs of battery storage is both interesting, fun and useful. But it's not the solution for the grid. Like it or not, for our grid to work, we need large heavy generators spinning with enormous inertial mass, what they are powered by doesn't matter from the grids perspective. Pick your poison - coal, gas, oil or atom. My choice would be atom power. Or we could go back to pen, paper, kerosene lamps and so on. Oh right, kerosene is fossil, how about whale oil? Wales are renewable. Or bees wax candles maybe? Oh right weren't the bees dying in many parts of the world? In either case, as it stands, when the wind is blowing, the price of electricity plummets to basically nothing. This should be as clear as can be that we already have enough, too many even, of these here windmills. How can the politicians actually be arguing for more of them? We clearly do not need more power when the wind is strong. A windy day and the price plummets to nothing. If the following day is a still day, the price can differ by a factor in the multiple of hundreds. Obviously there's enough wind power with these effects as is. To me it's farcical to even suggest we should build more.
