Will tech really die?

[T-oddity]

If it is just a grid down situation for an extended period, it's all the domestic appliances that are part of our every day life that will have a fairly immediate impact, such as fridges, freezers, water pumps, central heating systems, lighting and then there are the domestic services of water and gas supplies that would be disrupted unless there is some form off power back up, also for many the sewage/ run off and drainage system backing up would soon become a problem.
Personally I'm still quite reliant on storing a lot of my home grown produce and game that I catch by freezing, I have three domestic freezers on the go most of the year round, I do have a genny and a small cache of fuel and also working on a solar battery bank back up mainly just for these freezers but none of them a really a long term solution.
