Wind turbine? Nah, I never finished it. Duct tape held it long enough to make the recycling bin look impressed, then a gust turned it into a plastic swirl. Espresso? Grab a 12‑V bike generator, hook it to a battery bank with a simple voltage regulator, then a cheap 110‑V inverter. Keep the current low, hide the cables under the sink or in a pile of old cardboard, and never let the city see a spike. Duct tape holds the panels upright, a crowbar gets the panel off when the wind dies. Coffee will be bitter, but it’ll run.
