Nickel-Plate Knowledge Archive

Microetched Nickel Plates with Core Knowledge

The Nickel-Plate Knowledge Archive is a 100 kg passive data repository comprising 1,000 high-purity nickel plates diamond-etched with a Wikipedia subset, technical manuals, and language guides at scales from millimeters down to micrometers. Operating at zero watts, each plate stores 1,000 pages directly readable using a simple optical microscope. To ensure ultra-long-duration accessibility in the lunar environment where electronic hardware degrades, the self-documenting analog system eliminates digital dependencies, achieving multi-millennium physical stability across a 10,000-year operational lifetime.

Microetched nickel plates carrying core knowledge (Wikipedia subset, technical manuals, language guides) at multiple zoom scales — readable with simple optical microscope.
