DIY Flywheel Energy Storage on a small scale? : r/AskEngineers

For reference, I use a lead-acid battery as laptop/modem/general power backup in my home office. It''s 12V 36Ah, weighs 12kg and can deliver just over 350Wh of energy via an inverter over an 8-hour period. How big and heavy would a flywheel-energy-storage system to do the same thing be? (Max continuous power of my inverter setup is 500W).
