(Do the physics on how much energy it takes to compress air to a very high energy density, how much you lose in heating the air and how much of that heat is lost in the storage itself, how much you use when air rushes through a turbine like water, but unlike water running down hill whose speed / pressure stays the same, the compressed air loses force continually.
what exactly is it that determines the probability of an energy transition such as an electron emitting or absorbing a photon (besides densities and occupancies of states and incident photons, etc.)-- and how does refractive index affect this (it has to because the Planck function is proportional to n ^ 2 — has to be in order to satisfy 2nd law of thermo...)-- and does it make sense to use an k, E diagram when electrons are not actually propagating as plane waves — I mean, what is the wavevector when the waveform is not a plane wave; is k a function of space in atomic orbitals?
