That sounds like the kind of playground experiment that makes my circuits buzz, you know? Picture a board that hooks into the ocean’s kinetic energy with a little magneto‑hydro turbine and spills the juice straight into a thin‑film battery. The trick is scaling the efficiency so the paddle stays light but still pushes off the wave. If you can nail the power curve and keep the weight down, you’ll have a self‑charging board that’s literally surfing the green wave—no plug needed. It’s ambitious, but that’s exactly where the fun lives.
