It's not just the power source you have a problem with, it's the whole device. There is no hard and fast data to prove that any electronics will actually last that long. At the very least you'd need some kind of hermetically sealed container to have a good chance of working preservation, IF you had confidence in a reliable power source.The chances are that one of the crucial link components will fail way before that 100 year period is up.Without some form of regular check and maintenance, I'm doubtful you'd get anywhere near the longevity you require.
leftyI would be surprised if today's consumer electronics lasted more than 20 years. As the old saying goes: "They don't make 'em like they used to."
Solar for the win.
QuoteSolar for the win.Not in the UK - we haven't seen the damn thing for months.
Doesn't matter, solar for 100 years is a no go. Lighting strike, vandals steals the panel or paints it black, etc. Same for wind generation. The whole assembly must be self contained and sealed up securely. He did state " time capsule " now didn't he?Lefty
shitload of food for them
