Will tech really die?

[bigpaul]

at some point your technology(even if it can still function without mains power) will need spare parts, if the power grid is down it is unlikely that any spares will be manufactured, you are then down to "jury rigging" something from any scrap bits you can find-which might work for a while, but unless there is a huge "die off" millions of other people are doing the same so how long do you think this "pool" of spares is likely to last? not long probably." solar panels might work for up to 3 decades but the invertor, batteries and electronics you plug into wont, anything that relies on batteries (even rechargeable ones)is going to be worthless once the battery chemicals wear out and there is no more to be had."
