I know the basic idea; you turn the hand-crank on the torch and it generates electricity for the torch to run on, something like 60 turns of the hand-crank givess you 30 minutes of light. What I'm asking is, in essence, how does the kinetic energy get transformed into electrical energy and then into light energy? Sorry if my vocabulary is a bit sparse, I'm not very science-savvy.

Maybe I should *** some more detail? I don't mean like a glowstick; I mean like when I turn the handcrank it stores the energy into a battery and then when I turn the torch on it runs off the energy from that battery; How does the handcrank put energy into the battery? Thanks?

When turning the handcrank you are turning a generator. The generator then charges a battery. The battery then runs the light.
You are the energy source, the same as the sun solar panel, water turbine or a wind turbine.

The crank pushes and pulls a magenet through cylinrdical coil of wire, the magnetic fields cause the electons in the wire to flow into the battery (sometimes capacitors) and then the electricity is used from there to power the bulb, depending on the number of loops in the wire, its thickness and the strenght of the magnetic field, you get diffrent voltages.

just like a glow stick. you crack them and they release chemicals which togeather are luminescent. i dont know what chemicals exactly, but it is pretty basic stuff.
