The Search For The Zone blog
I feel like the Reading Links probably contain a bunch of information which will be helpful to understanding what's happening in the story with parallel universes, electricity, etc.
One excerpt I found in the Tesla link on electricity seems maybe pertinent:
"We are coming gradually, but surely, to the fusion of bodies and reduction of all kinds of ores--even of iron ores--by the use of electricity, and in each of these departments great realizations are probable."
I wonder if maybe this is a hint to what happened with Dougie and the black box in Argentina?
