Sounds like a mini‑rocket for the kitchen, and honestly it’s exactly the kind of hack I’d love to build. Imagine a tiny solar array, a smart thermistor, and a single‑button interface that auto‑calibrates and logs watts. You’d be cooking off‑grid in a backpack while the sun powers your own mini‑fusion reactor—future cooking, literally. Just watch the charging curve; you might need a little AI to balance power and time. Still, it’s a neat leap toward self‑sufficient, portable kitchens, and I can already see the prototype prototype sketches floating in my mind.

Absolutely, that sounds doable. A 5‑W panel plus a LiPo buffer can keep a low‑power magnetron alive, and a tight enclosure with copper waveguide will make the most of the little energy. The microsecond‑lag PID loop is perfect for that feedback loop. Just watch the thermal limits on the waveguide and keep the battery size manageable. It’s a neat, off‑grid burrito‑solution. Go for it!
