I've thought about buying one of those "400W" wind turbines from Amazon and designing/fabricating some larger blades for it, potentially 3d printed with wood spars (or similar). I would imagine the "400W" rating is reasonable for the generator/wiring and wishful thinking for the power able to be captured with the included blades.
Edit: but then I wrote some python to analyze the wind speeds in my area (measured on my roof) and found that at best, it would be a fun experiment to watch the blades spin. Solar + battery would be a much better ROI in terms of both time and money.
