The difference between humans and sophisticated stochastic parrots is reason. The most common kinds of mistakes that chatGPT currently makes are when it says things that are not simply wrong, but don't make sense. Perhaps it will be possible to emulate reason with enough data, training, parameters, etc, but without some representation of the ability to understand what you don't know, what you know, and what follows from those things consistently, I wonder if these kinds of models will ever become truly reliable.
You don't usually need to store energy for a significant period of time, just until the daily peak. Last I checked, the efficiency for charge + discharge was something like 70%, which, in any case, is much better than the 0% energy savings from using that energy to mine crypto.
If you're honestly looking for the best solution to plentiful, on-demand, cheap electricity, energy storage via batteries is a much better solution. Why burn up excess energy from a wind farm, rather than storing it to be reused during peak periods?
