  1. I wonder if thinking about this concept (especially the speed of electrons) affects one's speculations about how bodily damage is done by lightning. I lazily assumed that a cascade of electron motion along the electric field induced by lightning can lead to collisional energy losses and heat generation within the human body hit by the lightning. So how is that damage created? I've never really known. Once again, I am surprised by lacking a certain knowledge I assumed I possess. While I feel embarrassed at hubris leading to simply assume I understood, I am excited at the prospect of learning about another area of knowledge regarding the magical universe around us.

  2. Argh! I just realized something I have not seen in the tens of comments I read. (Sorry, but I can't read the nearly 50k written!) Lots of folks focus on the energy that would be directly transferred to the light bulb. However, the wires also transfer energy to the parallel wires connected to the lamp. So, the process of transfer is really growing continuously, not just acting like a spike. The two parallel parts of the circuit are going to have inductive effects that spread linearly at the speed of light. This will have perhaps sufficient energy to really light up the lamp, depending on the energy needed. I am far too unwilling to apply math to what looks like to me to be a rather non-linear problem more appropriate for specialists to simplify rather than a wannabe like me.
