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.

if you drill a hole in the U.S. ,through the center of the earth, to the other side to, lets say china. and then someone in the U.S. jumped in the hole and was falling and reached the center of the earth. does he keeping falling until he flies out of the hole on the china side or does gravity reverse and he starts going back towards U.S. Basically its a question about gravity. i hope you understand what i mean. a little bit hard to explain it while typing. i asked my brother and he knew what i meant so it shouldnt be too hard. its a hypothetical question. i know you cant drill through center of earth. well atleast with todays technology.
