TIL at the largest flywheel energy storage in the world, Each 775-ton flywheel can spin up to 225 rpm and store 3.75 GJ, roughly the same amount of kinetic energy as a train weighing 5,000 tons traveling at 140 kilometres per hour (87 mph). by whatilearned November 19, 2021, 12:52 am Read more: https://en.wikipedia.org/wiki/Joint_European_Torus What do you think? 12 Points Upvote Downvote 775tonamountEnergyflywheelGJ44hourkilometreskineticlargestmphroughlyRPMspinstoragestoreTILToday I learnedtonstraintravelingWeighingWorld See more Previous article When you die what part of the body dies last?

Log in to Reply You know they had a plan to power cars with flywheels abut 20 some years ago; I remember reading about it in Discover magazine. Electric and magnetically powered and made out of carbon and iron, no chemical batteries at all. But the big automakers decides gasoline/battery was the way to go so a potentially game changing innovation never happened. Log in to Reply Am i going to the wrong article? This link takes me to a wikipedia page talking about a fusion reactor and plasma storage, magnetic fields….not one thing about a flywheel that i saw.
