LiFi communication masks

In October 2025, the Republic of Palau will host a world first : the very first underwater conversation broadcast live using Li-Fi technology .

For the first time in history, a head of state will speak under the waves, alongside freediver Merle Liivand , with the participation of Gunter Pauli and Idriss Aberkane .

The message is universal: the ocean is not a barrier, but a bridge between people, innovation and life.

✨ Why this is historic

First presidential underwater conversation
Voice transmission via Li-Fi (light, not radio waves, which do not pass underwater)
Bone conduction masks for a natural and fluid exchange
From Palau to the rest of the world: a strong signal for innovation, biodiversity and the future of the planet

🌍 A global collaboration

This event would not have been possible without cooperation across five continents , bringing together:

The Government and the Presidency of Palau
Blue Education & Blue Innovations
Acer , technology partner
The Palau Visitors Authority (PVA) and the Palau International Coral Reef Center (PICRC)
An international team of engineers, divers, producers and storytellers

⚡ Technology: When light becomes a voice

As early as 1880, Alexander Graham Bell was already experimenting with his "photophone," capable of transmitting voice via a beam of light.
Li-Fi technology allows data to be transmitted through LEDs, faster than 5G , securely, and in a way that is impossible to hack.

In October 2025, for the first time, this innovation will allow human voices to travel underwater – as dolphins and whales have been doing for millions of years.

📅 And then what?

The first production run of 100 Li-Fi underwater communication systems will be launched in 2026, opening up new possibilities for science, exploration, education and ocean protection.
