- SketchySeaBeast 3y agoIt seems an impractical solution for a car, and better used as a massive and immobile mechanism where you can trade out a lot of that velocity for mass, and where your housing isn't actively fighting the storage the whole time. I would love for someone to do the math on how much kinetic energy you'd need to store in a wheel that can fit in the engine compartment to allow a 2 ton vehicle to go 200 miles in stop and go traffic. Not all energy storage solutions can work in every problem. We won't be using hydroelectric for cars either.

- cman1444 3y agoI've wondered in the past if a giant flywheel the size of, say, a building and filled with a heavy material like concrete could store enough energy to make a difference in intra-day grid loads.

- aitchnyu 3y agoI was amazed at flywheel UPS 20 years back. Why arent they more popular by now? https://en.wikipedia.org/wiki/Flywheel_energy_storage#Comparison_to_electric_batteries https://en.wikipedia.org/wiki/Flywheel_energy_storage#Compar...
