Wow a device that gives out wireless power! nice too bad the transmitter and receiver unit should be in synch so the power transfer can happen, my guess is that device is sort of universal, but the scientist lady did power her computer by plugging that device in.. That scene just got me nuts for a while..
In the sniper scenario, so did I miss somthing and that house had a mountain behind it? and why didn't the militia surrounded the place and only came from the front and be easy targets?
I don't remember the scene exactly, but I thought she just hung it on peg above the desk and the devices started to power up, she may have hit a power switch on the computer?
The shelf above the computer had a whole bunch of lead-acid car batteries hooked together with what looked like jumper cables.. She activated the pendant and then the computer came up, powered by the batteries. Likewise, when the pendant came up in the living room, the CD player turned on with its own batteries, and the Iphone, the same.
I suspect they are trying to suggest that the power is off because of some kind of dampening field, and the pendant cancels out that dampening field.
In the opening, have you noticed that they show only the western hemisphere going dark, never Europe, Asia, Africa or Australia. Did the power go out there or not?
