You’ve got a good eye for this. Start with the big stuff and work your way down. Grab an old car battery or two, strip out the terminals, and bolt a low‑power solar panel in front of it – that gives you a simple battery bank you can hook up to a few LED strip lights or a makeshift lantern. If you’ve got an old radio, you can fry the circuits, replace the tubes with LEDs, and use it as a “solar‑charged light‑up” station for a few nights. Another trick is to find any old wind turbine or even a big fan. Flip it to work as a generator – you’ll need a few extra wires and a small inverter, but you can power a strip of LED’s from it. The trick is to keep the load low; a dozen or so LED’s will be enough to light a kitchen, a communal table, or a small shelter. Finally, gather any aluminum cans or tin cans and paint them with conductive paint to make cheap “circuit boards.” You can connect them to a battery or a small solar panel and use the heat from the metal as a low‑cost light source. Keep everything modular so people can swap parts out if one thing breaks. That way, the community can keep the lights on, learn to fix things, and feel a little less like they’re in a wasteland.
