Ten thousand mirrors focus sunlight into one point hotter than 3,000°C. We pushed a 4 cm strip steak into it: charcoal outside, raw inside, in one second. So we half closed the shutters, blurred the focus and seared it on 250°C cast iron instead.

• Solar furnace: 63 sun-tracking mirrors feed a curved wall of about 10,000 mirrors
• About 1 MW at the focus, over 3,000°C
• Too much heat only burns the surface, so: defocus, sear at 250°C, core 55°C (medium rare)

Note: an AI-generated hypothetical experiment, not filmed at a real solar furnace. Don't try this with mirrors or a magnifying glass.
