The average laptop is 65W. So the 40 amp solar battery station I built with a 100w panel could run a laptop 7 hours a day without any issues at all. Plenty of time to get actionable information out of it.

Sure, solar works. And batteries work - for about 3000 charge-discharge cycles.

That’s… a lot of cycles. That’s almost a decade. Plenty of time to build an electric generator from scratch by traveling on foot to a copper mine and smelting the wire yourself. Unless you manage to pull an alternator from a car that can’t find gasoline and save yourself the trip. From that you could make a gravity battery or any number of other options.

Point being, after 3000 cycles, it’s toast and there’s no fresh bread available.
Yes, you could construct something, but I think you’d be pretty amazed at how maintenance intensive a 1kWh gravity battery is.
