[QUOTE="Which Tyler, post: 1099998, member: 73592"] I thought that was just a big Lithium battery pack? Which is precisely what I'm looking for an alternative for. A mechanical "battery" is something like a flywheel - convert electric energy (or even rotary kinetic in the case of a wind turbine) I to rotary kinetic energy, making the wheel turn ever faster when excess electricity is being used, and bleeding it back out when you're using more than you produce. Or for potential energy, when using more electricity than you produce, pump water (for example) uphill, then when you're using more than you produce, allow it back down through an HEP turbine. When Formula 1 first introduced KERS breaking, one of the teams (Williams?) Developed a flywheel energy storage, rather than lithium, but were forced to ditch it by the FIA. IIRC because it worked too well compared to what every other team did. ETA: Nope, it was size restrictions due to other changes I troduced at the same time: [URL]https://www.autosport.com/f1/news/williams-opts-for-battery-kers-in-2011-4441964/4441964/[/URL] Also found this explained here: [URL]https://www.racecar-engineering.com/articles/f1/williams-f1-kers-explained/[/URL] [/QUOTE]
