Welcome to the new episode of the TNW Podcast — the show where we discuss the latest developments in the European technology ecosystem and feature interviews with some of the most interesting people in the industry.

In today’s episode, Linnea and Andrii talk about energy use at data centres, the state of Northvolt, submarine communications, and a few things in between.

You will also hear an interview with Chiara Petrioli, CEO and founder of Wsense, a company that’s created what it calls the underwater Wi-Fi to help preserve cultural heritage, monitor critical infrastructure, and do a lot of other things. Andrii sat down with Chiara last week in Rome, during the Rome Startup Week, to learn more about the company, the technology it’s developed, and the future the founder has envisioned.

Here are the stories and things mentioned in the episode:
