Sustainability 500 years
Despite stringent techniques, it is impossible to preserve the jewels of our history. It is estimated that 99% of academic materials produced in the last 2,000 years have disappeared.
Sustainability 20 years
Information technology is subject to a high degree of obsolescence. For example, the average lifespan of a USB key is 10 years, that of a hard disk is 34.
The Natinsa medium
Sustainability 2 million years
Natinsa’s ingenious team has created a medium that makes it possible to preserve knowledge, with a lifespan of more than 2 million years, and without the need for any additional technology to read it. This is why the Natinsa support was chosen to be sent to the moon in the SANCTUARY time capsule.
On a daily basis, we work with an unalterable medium: the sapphire disc; to a rare degree of precision: on the scale of the nanometer. Just how small is “nano”? One nanometer is 25 million times smaller than an inch. A sheet of paper is about 100,000 nm thick. One nanometer is about as long as your fingernail grows in one second.
The sapphire disc
Natinsa’s sapphire disc is 4 inches diameter and 1/25 of an inch thick. It is resistant to fire, salt water, scratches, x-rays and all chemicals. The lifespan of a sapphire disc is over 2 million years.
Nano-engraving is achieved by depositing a metallic film on the sapphire disc, applying a stencil with microscopic openings reproducing the text, and removing part of this film through the stencil with the help of a plasma.
To view our disc, we provide a nanoscope, which is connected by wifi to your smartphone and/or tablet. It also offers the possibility to take High Definition pictures.
