I've watched the videos and read a lot of posts on here about compressed air storage. I read that a filled scuba tank has over a million joules? I'm trying to visualize what happens if you suddenly release all the energy from that tank, it should be enough to move or brake/stop a sizable car? example I had read was a 1200 kg car going 20 m/s needs 24000 newtons to stop? so, a scuba tank has enough energy stored to stop this 1200kg multiple times ? if that same 1200kg car is at rest, and you wanted to vent the tank to try to move it if you vent it slow enough, you wont overcome resistance and will empty the tank without it even moving? If I vent the tank in an instant how do I calculate how far the vehicle is pushed? If I vent slower, say 5 or 20 seconds, how do I calculate how that effects the distance a vehicle is pushed. Thanks for any explanations, I've been reading and not really understanding.
