This seems like the right kind of idea, but I’m unclear about how it charges a car fast. I understand the storage idea: if these kinetic batteries work, they could be very useful. I don’t know how efficient they are. I think in terms of potential and kinetic mechanical energy like an old-time cartoon, so it’s like the flywheel has been spun to a point where it can return energy, which takes energy to get there, which I assume comes from the power grid and/or solar cells, and then that energy has to be suspended, which could be a mechanical stop (which takes some energy to put in place and remove, but that’s true in equipment generally), and then it has to flow out, which means it has to be converted into power.
