5G from Space: How Constellation Is Connecting the Disconnected

What if you could stream Netflix from the middle of the Sahara—thanks to 5G from space? In this episode, we explore the bold vision of Constellation Technologies, a Paris-based startup building a low-orbit satellite network to deliver fiber-like 5G speeds anywhere on Earth.

Founded by former World Black engineer Charles Delfieux, Constellation is launching tiny satellites in very low Earth orbit (VLEO) to bring fast, reliable, and sustainable internet to remote villages, ships, farms, and more. Their satellites offer speeds up to 150 Mbps down, 50 Mbps up, and under 30ms latency—all while reducing space junk and using recycled 5G components to cut costs.

What’s revolutionary is their telco-friendly model: instead of competing with telecom giants, Constellation partners with them—offering bandwidth and terminals that carriers like Orange or AT&T can resell, turning space into an extension of existing networks.

Tune in to hear how this sci-fi sounding mission is becoming a reality, and why space might just be the key to true global connectivity.

Drones That Defy Physics: Inside Aerix’s Omnidirectional Revolution

What if a drone could flip upside down, spin in place, and hold steady in a 100 km/h storm? In this episode, we explore the mind-blowing innovation of Aerix Systems, a French deep tech startup founded in 2020 by two engineering students in Gironde.

Aerix has developed the world’s first omnidirectional propulsion system—think drone engines mounted on gimbals that let it thrust in any direction. Their modular platform, the M1, can reach 200 km/h in 2.5 seconds, carry up to 10 kg, and maintain stability even in extreme weather. It's not just for aerial stunts—Aerix is targeting real-world applications in energy, construction, and defense, like inspecting wind turbines during storms or intercepting rogue drones from kilometers away.

Co-founders Clément Picaud and Hugo Mayounove have built not just drones, but plug-and-play aerial robots with full computing, sensor payloads, and autonomous navigation—making Aerix a true leap forward in drone agility and versatility.

Tune in to discover how Aerix is pushing the boundaries of flight and redefining what drones can do.

In this episode, we dive into the story of e-Taranis, a French cleantech startup based in the Basque Country that's aiming to democratize wind power for everyday households. Their innovation, Alaé, is a compact, ultra-quiet, and eco-friendly wind turbine designed specifically for urban and suburban homes.

Unlike traditional turbines, Alaé starts producing clean energy at wind speeds as low as 10 km/h, making it practical even in less windy regions. It’s built with 97% recyclable materials, blends into the environment with minimal visual impact, and is a big step forward in sustainable, local energy production.

e-Taranis isn’t just selling wind turbines—they’re promoting a personal energy revolution, empowering individuals to reduce their carbon footprint while gaining energy independence.

Tune in to hear how design, sustainability, and local innovation come together in this inspiring deep tech story.
