Does the math, math if you get enough Batteries so that you can use a lot of it at night, without much buyback? Or does the high cost of storage not make the math quite math.

I'm currently paying 10c/kwh off peak, and most of our power is used off peak, I doubt a battery would pay for itself any time soon. Besides, they're not the most environmentally friendly option.

Just totally random, but I suddenly thought of when they first introduced hybrid power into F1, and kept it quite open for the manufacturers to come up with their own solution, and at least one team (from memory) tested flywheels.

Wondered if someones done a residential scale flywheel, and it seems like there's been at least some research into it.

Those systems more or less completely charged and discharged in each corner from memory, there wasn't all that much energy in the system.

The only realistic use case I can think of would be keeping power on long enough for a generator to spin up. Otherwise you'd have a moving part with a scary amount of inertia that needs routine maintenance, and otherwise just sits there.

True. Does sound like a lot of maintenance and dangerr
