The wiki says it's 484 megajoules, delivered in 3 seconds. That is equivalent to 134 mega-watthours,
For a potentially more useful arbitrary metric, that's a bit less than two Model S batteries. Except it delivers all the energy in seconds, and charges in 45 seconds, and isn't limited to a few hundred charge cycles. It's a kinetic flywheel storage system, but I wonder if it would be built today using a giant lithium-ion pack (many Tesla PowerWalls, basically) or a supercap array.
- maxerickson 9y ago134 kilowatt-hours. 1 megawatt-hour is 3600 megajoules.
- LeifCarrotson 9y agoThank you for the correction. It seems like this sort of energy could be very feasible with supercaps, lithium-ion, or lead acid, at that level.
- maxerickson 9y agoLike you said in your other comment, the energy is a couple Tesla batteries. It's the power and cycling requirements that are hard.
- NikolaeVarius 9y agoDoubt it. A large purpose of this kind of system is to make it non explosive,
- Robotbeat 9y agoFlywheels fail by basically exploding.
